api plan 62 mechanical seal quotation

API Plan 62 delivers an external quench fluid to the atmospheric side of the seal. A typical application in a refinery is the prevention of coking on seal faces in hot hydrocarbon service by employing a steam quench. Nitrogen or clean water may also be used to quench or cool and clean the atmospheric side of the seal.

See page 77 of the Mechanical Seal Support Systems Application Guide for additional details and ordering information. Contact your authorized Swagelok sales and service center for information on optional components.

Seal Support Systems operate to control the fluid in between and around the seal faces whether cleaning, cooling or heating the seal media or providing a separate fluid to the mechanical seal.

Some applications are simply not suitable for mechanical seals e. g applications which are corrosive, abrasive, crystallizing or precipitative. In order for a mechanical seal to operate under these applications with reasonable mean time between failure (MTBF), either the seal fluid requires treatment before coming into contact with the seal faces or an external fluid is required which is compatible with the process. Also double mechanical seals will require some sort of fluid to act as a buffer or barrier fluid andthe system which provides this buffer or barrier fluid are Seal Support Systems.

A seal plan is used in conjunction with the API 682 Standard and it is a way to formalise the different seal support systems into a standard. It consists of seal flush plans, buffer & barrier fluid plans, quench plans and gas supply plans.

The API Plan 53A is a dual seal plan where a barrier fluid is supplied to a double mechanical seal between the 2 sets of faces of the mechanical seal.

Plan 62 is a quench seal plan where a fluid is supplied to the space between the atmospheric side of the mechanical seal and the throttle bushing on the shaft.

Flowserve provides Seal Support Systems for in accordance with API 682 but can also provide systems outside of this standard, if the application dictates.

Our Mechanical Seal specialists can advise you on the appropriate selection of a seal support system which will deliver years of reliable service and operating cost savings in the longer term.

After more than five years of planning, the American Petroleum Institute (API) is preparing to release the 4th edition of API Standard 682 (ISO 21049:2011). The API 682 standard, which dates back to 1994 and is formally known as Shaft Sealing Systems for Centrifugal and Rotary Pumps, offers specifications and best practices for mechanical seals and systems to pump end users.

The standard’s latest edition began to take shape in 2006, when API formed a 4th edition task force to respond to end users’ questions and comments about previous editions. The task force soon realized that major changes, including reorganization and editing, would be necessary. While addressing every aspect of the resulting 4th edition (which is more than 250 pages long) would be impossible, this article summarizes the standard’s main points.

Those who use API 682 should understand the standard’s scope and remember that the standard does not include specifications for equipment outside that scope, such as engineered seals or mixers. Another important but often misunderstood point is that API 682’s figures are illustrative and not normative in their entirety.

For example, one of API 682’s figures shows a fixed throttle bushing combined with a rotating Type A seal, but seal manufacturers do not always have to combine these two components. The standard provides normative details in clauses and tables to help purchasers distinguish between requirements and suggestions.

The 4th edition continues to divide seals into three categories, three types and three arrangements. For all practical purposes, seal manufacturers can combine a seal’s component parts into nearly any orientation or configuration. Each orientation and configuration has advantages and disadvantages with respect to certain applications, performance and system disturbances.

Before the 4th edition, API 682 did not specify a minimum clearance between the inside diameter of a stationary seal part and the outside diameter of a rotating seal part. The 4th edition specifies this minimum clearance—typically the clearance between the sleeve and the mating ring. The specified clearances are representative of standard clearances that end users have used for decades. End users should not consider seal components to be “shaft catchers” to restrict shaft movement. The minimum clearance specified in API 682 also applies only to equipment within the standard’s scope. Equipment outside that scope, such as non-cartridge seals, older pumps, non-API 610 pumps and certain severe services, might benefit from larger clearances.

The new standard also updates the default bushings for the gland plate for the three seal categories. Fixed throttle bushings are now the default for Category 1 only, while floating bushings are the default for Categories 2 and 3.

While the 4th edition features the recommended seal selection procedure from the standard’s first three editions, it adds an alternative selection method in Annex A. Proposed by task force member Michael Goodrich, this alternative method recommends using material data sheet information to select a sealing arrangement.

Plan 65 is now subdivided into 65A and 65B. End users can use Plan 65A to detect an excessive leakage flow rate and Plan 65B to detect a certain amount of cumulative leakage.

Plans 66A and 66B are new to the standard, although end users have used them previously in pipeline applications. These plans detect and restrict excessive leakage rates in case of an Arrangement 1 seal failure.

The 4th edition now requires Plan 52, 53A, 53B and 53C systems to have a sufficient working volume of buffer or barrier fluid for at least 28 days of operation without refilling. As a point of reference, the default reservoir for Plans 52 and 53A has a three-gallon capacity, or pot, for pump shafts smaller than 2.5 inches and a five-gallon pot for larger shaft sizes. Plan 53C must have the same working volume of fluid as Plan 53A. For Plan 53B, the default bladder and accumulator sizes are five gallons and nine gallons, respectively. The design of Plan 53B systems can be complex, especially when ambient temperatures vary widely, and purchasers should become familiar with the calculations and procedures in the 4th edition’s Annex F tutorial. The new edition also discusses the option of adding a pressure gauge and isolation valve to check the accumulator or bladder’s integrity in a Plan 53B system.

The 4th edition has revised the data sheets in Annex C extensively to make them the same for all seal categories. Only two data sheets are included in the 4th edition—one in metric units and one in U.S. customary units. The new edition also folds Annex J into Annex E.

Previous editions of API 682 required metal plugs and anaerobic sealants when shipping new or repaired cartridges. After much debate, the task force decided that threaded connection points should be protected with plastic plugs for shipment. These plastic plugs should be red and have center tabs that operators can pull easily to distinguish the plugs from metal plugs. Shippers should also attach yellow warning tags to the plugs to indicate that end users need to remove the plugs before operation.

Although tutorial notes are scattered throughout API 682, this edition expands the tutorial section, Annex F, from seven pages to 42 pages. The expanded annex includes illustrative calculations. In particular, users interested in systems such as Plan 53B will find Annex F to be useful.

The 4th edition of API 682 is the product of more than 20 years of discussion, debate, usage and peer review. It includes a strong set of defaults and is by far the best and most logical starting point for mechanical seal and systems use. Equipment operators should take the time to familiarize themselves with API 682 to get the most out of this comprehensive standard.

Most pump experts would agree that mechanical seals on a rotating industrial pump are one of the most important components regarding pump performance and longevity.  Rotating industrial pumps are designed with double mechanical seals located at the shaft that connects the impeller or rotor to the motor.  As the motor applies force to the shaft, the shaft spins, which in turn, spins the impeller or rotor which is connected to the far end of the shaft.  This spinning action of the shaft and impeller or rotor is what produces the flow rate of the pump.  The double mechanical seals are a wear component that must be replaced periodically or the pump will not perform as expected, or even worse if these seals fail it can cause a catastrophic failure resulting in substantial cost to repair or replace the pump.

Most often, failure of the mechanical seals is due to being exposed to excessive heat that is generated by the turning or spinning action of the shaft.  This build-up of excessive heat at this area of the pump is also the reason why many rotating industrial pumps cannot operate in a run-dry condition.  When a pump runs dry without fluid circulating through the wetted path, a greater amount of heat is generated at the mechanical seals.  Subjecting the mechanical seals to a greater amount of heat than what they can withstand causes premature failure of the seals.

A solution to avoiding the overheating of mechanical seals in a rotating industrial pump is Seal Support Systems.  Seal Support Systems are designed to flush the mechanical seal area of the pump with fluid. This flushing action reduces the build-up of heat, increases the longevity of the pump, and avoids premature failure of the mechanical seals due to overheating.

There are a number of different Seal Support System designs available on rotating industrial pumps.  Some of the different designs available meet the American Petroleum Institute (API) standards for pumps that are to be used in the Oil and Gas industry.  A couple of the most prevalent API standards for Seal Support Systems API Plan 53A and API Plan 62.  Both of these systems are designed differently; The API Plan 53A Seal Support System is designed with a closed-loop system, and API Plan 62 Seal Support System is designed with an open system where the flushing fluid is immediately discarded from the pump directly after the flushing fluid flows through the mechanical seal area and expels the heat.

Both of these seal support systems are very effective at reducing heat build-up that can destroy mechanical seals.  Although both of the types of seal support systems reduce heat build-up, some environments require the use of a closed-loop seal support system to avoid the flushing fluid from exiting the pump and contaminating the area that the pump is operating.

FLUSH PLANS FOR MECHANICAL SEALS – INTRODUCTIONPumps and seals are being installed into increasingly difficult services. Forsuccessful operation of mechanical seals, the environment and care of the sealsrequire more sophisticated seal chambers and flushing arrangements. This sectionof the Dean Pump Price Book is designed to allow the application and pricing offlush plans suitable to meet the requirements for the mechanical seal.The American Petroleum Institute (API) has defined certain seal flusharrangements known by their plan numbers. Later, the flush plans developed forthe ANSI standard followed suit and placed the digits "73" in front of the API plannumber to achieve some standardization within the process industry. Thus, APIplan 11 becomes and ANSI Plan 7311.Dean Pump has worked with many engineering houses and customers over theyears and has developed a great deal of experience with sealing systems. WhileDean will quote any flush system requirement as requested by a particularcustomer, it has been found that the API/ANSI systems generally meet or exceedmost customer requirements. In addition, Dean Pump developed the Seal GuardEnvironment systems that provide the ultimate mechanical seal flush plan. Forsystems that do not require ANSI/API flush plans, Dean Pump has also includedthe P1200 loop, which is a basic low cost flush plan to satisfy the economyminded customer.The experience of Dean Pump is contained in these price pages. Many of theflush plans are divided into "Toxic/Flammable" and "Non-Toxic/Non-Flammable“services. The information on these plans along with the details described in the"Special Notes" section can be used as a guide in quoting and discussing optionswith customers. The "fine print" in the Special Notes section provides a multitude ofdetails about each flush system. For example, a customer requesting all socketwelded connections can not have every connection welded. Some accommodationmust be made for disconnecting the system. Being aware of the requirements ofthe customer and the manufacturing limitations of the product is extremely helpful.API flush plans are based on the 7 th Edition of API610. Newer versions of the APIspecifications has limited the cooling and flushing options available.Finally, if there are any doubts, questions, or comments, please feel free to call theFactory and the seal vendor.Effective: FEBRUARY 2011 • Replaces: NEWPage 1

SEAL GUARD SYSTEMS – PRODUCT DESCRIPTIONSeal Guard systems are designed to provide a clean liquid for seal flushing thatprovides protection for the mechanical seal in the pump seal chamber. Dean Pumpoffers two basic systems to guard against mechanical seal failure. These systemswill also help to prolong the life of the seal. Both systems are filtration systemsinstalled into the seal flush lines to remove stray abrasive particles which causeseal face wear.Seal Guard A - is designed for filtration only. Particles larger than 10 microns arefiltered from the system using clean-able or replaceable 316SS woven filterelements.Seal Guard B - is designed for high temperature applications and includes a heatexchanger installed ahead of the replaceable filter elements for both filtration andtemperature control.Seal Guard systems are most often used with MIN-FLO Bushings in the pump sealchamber. These bushings restrict the flow from the seal chamber back into thepump during operation and increases the effectiveness of the Seal Guard system.Seal Guards can be used on any pump product line. Their sale is not limited toDean Pump products. Seal Guards are hydrostatically tested but do not meet anyindustrial standard and are not for application to API610 series pumps. Seal Guardapplications must be limited to iron or steel pumps and are not suitable forapplications that require alloy materials.The Seal Guard system is fully described in Bulletin A2000.Effective: FEBRUARY 2011 • Replaces: NEWPage 2

SOME COMMENTS AND RECOMMENDATIONSABOUT API/ANSI FLUSH PLANSThere are two organizations in the United States which have taken the lead in developingacceptable standards for the pump industry. The American Petroleum Institute (API) and AmericanNational Standards Institute (ANSI) have outlined a number of flush plans which encompass themajority of applications. API610 is mainly recognized as a standard which defines the qualityrequirements of a pump and/or system. ANSI-B73.1 is viewed as more of a dimensional and featurestandard. ANSI plans are designated the same as API plans except for the addition of a "73" prefixon the plan number. For example, an API Plan 21 is designated as an ANSI Plan 7321.API and ANSI flush plans are similar and upon initial examination look nearly identical. However,there are definite differences in their construction. Often, API flush plans, which are historicallylocated in refinery environments, are piped and welded. ANSI plans, on the other hand, can utilizetubing. Another notable difference is in the API plan 52/53 and the ANSI plan 7352/7353. APIspecifies Schedule 40 minimum thickness vessels. ANSI allows for the use Schedule 10 vessels. Allof the plans are offered in steel and stainless steel construction. They also have differingconstructions for Toxic/Flammable or Nontoxic/Nonflammable applications.Meeting the customer"s specific requirements is the most important consideration in applying theseplans. Many customers modify their individual requirements from the API and ANSI specifications.Sometimes these are more stringent rules than the API and ANSI specifications. These must takeprecedence over the standard flush plans. There are some limitations as to what the flush plans canor cannot accomplish. The Special Application Notes section on each sheet identifies the particularlimitations of each of the flush plans. For example, a flush loop which requires socket welded jointscan not have all the connections welded some provision must be made to allow for disassembly andrepair.When applying a particular flush plan to a specific job, great care should be taken to insure theneeds of the customer are met. Do not select a plan based solely upon pricing. In general, most APIplans require piping and many require welded joints. Note that these are the most expensive plans.A few API services permit the less expensive plans but, the customer"s requirements takeprecedence. ANSI, on the other hand, is much less specific but still requires close analysis of thecustomer"s specifications and requirements for guidance. However, API plans are often seen onANSI type pumps. Oil companies are very likely to request the more expensive plan and will pay forit. Do not make errors in this area. If there is any doubt, or questions regarding plan selection, sendthe specification/ requirements to the factory for review. The factory will provide any comments,limitations, and pricing that is required.Effective: FEBRUARY 2011 • Replaces: NEWPage 5
