Incorrect lapping and or the use of the wrong abrasives and lapping tools are the most common reasons for leaking valves after repair, leading to lengthened servicing turnaround times. For time critical plant shutdowns, it’s very important that seats and seals are repaired correctly first time.

Kemet have produced a lapping kit that can be used on Tyco, Crosby, and Anderson Greenwood pressure relief valves. The kit consists of:15 Lapping / Polishing blocks, double sided with Kemet composite (D through T2 orifice sizes)

Safety valves and pressure relief valves protect vessels, piping systems, and equipment from overpressure, which, if unchecked, can not only damage a system but potentially cause an explosion. Because these valves play such an important role, it’s absolutely essential that the right valve is used every time.

The valve size must correspond to the size of the inlet and discharge piping. The National Board specifies that the both the inlet piping and the discharge piping connected to the valve must be at least as large as the inlet/discharge opening on the valve itself.

The connection types are also important. For example, is the connection male or female? Flanged? All of these factors help determine which valve to use.

The set pressure of the valve must not exceed the maximum allowable working pressure (MAWP) of the boiler or other vessel. What this means is that thevalve must open at or below the MAWP of the equipment. In turn, the MAWP of the equipment should be at least 10% greater than the highest expected operating pressure under normal circumstances.

Temperature affects the volume and viscosity of the gas or liquid flowing through the system. Temperature also helps determine the ideal material of construction for the valve. For example, steel valves can handle higher operating temperatures than valves made of either bronze or iron. Both the operating and the relieving temperature must be taken into account.

Back pressure, which may be constant or variable, is pressure on the outlet side of the pressure relief valve as a result of the pressure in the discharge system. It can affect the set pressure of the upstream valve and cause it to pop open repeatedly, which can damage the valve.

For installations with variable back pressure, valves should be selected so that the back pressure doesn’t exceed 10% of the valve set pressure. For installations with high levels of constant back pressure, a bellows-sealed valve or pilot-operated valve may be required.

Different types of service (steam, air, gas, etc.) require different valves. In addition, the valve material of construction needs to be appropriate for the service. For example, valves made of stainless steel are preferable for corrosive media.

Safety valves and relief valves must be able to relieve pressure at a certain capacity. The required capacity is determined by several factors including the geometry of the valve, the temperature of the media, and the relief discharge area.

These are just the basic factors that must be considered when selecting and sizing safety valves and relief valves. You must also consider the physical dimensions of the equipment and the plant, as well as other factors related to the environment in which the valve will operate.

Pressure relief load determination is a common task carry out by process engineer whilst Pressure Relief Valve (PRV) sizing and selection is normally conducted by vendor with the coordination with Instrumentation Engineer (most companies). However, pre-selection and sizing of PRV may need to be carried by process engineer during conceptual and Front End Engineering Design (FEED) stage in order to provide best estimate of information for Flare system design.

Thus, PRV sizing is considered one of the important task for process engineer.There are many Pressure relief valve vendors offer free PRV sizing program. However, a few out there are really good, reliable and impressive. Farris SIZEMASTER, Dresser CONSOLIDATED SRVS and Tyco PRV2SIZE consider one of those. Farris SIZEMASTERNow you can accurately size and select a pressure relief valves for any combination of process applications with SizeMaster™ Mark IV pressure relief valve engineering software.

This program for Windows® (all versions) brings unprecedented integration of standard engineering practice to the task of sizing and selecting pressure relief valves.With SizeMaster Mark IV software, you can define as few as one or as many as 64 different sizing scenarios including blocked flow, fire, thermal and tube rupture, from a scenario matrix grid. Selection of the pressure relief valve is automatically based on the relief area of the worst case scenario. Various Wizards make the most complicated task simple; for instance, the Capacity Wizard allows you to determine accurate vapor generation for vessels of all types. Tyco PRV2SIZETYCO PRV2SIZE Pressure Relief Valve and Vent Sizing & Selection software is the latest innovation in pressure relief sizing software to meet demands for a simple and integrated solution.

It is the first program from Tyco Flow Control to offer integrated sizing, selection, and configuration of Anderson Greenwood, Crosby, and Varec brand pressure relief devices.If you are aware of other PSV sizing software which is considered reliable, why not let us know? OR if you are friend of one of above softwares, why not share your thought with us?Related Post. 10 Comments: said.Great Find. Good Softwares said.Thanks and welcome, Jim.

Maybe can do on PSV/valve database mgmt free software afterward. Thank you said.Good write up and good suggestions for software. First time ot this site.

Click "Download." Anonymous said.Tyco SafetySize is no longer available. The program has retired. A new program has replaced it called "TYCO PRV2SIZE". It is still vendor related cause the vendor wrote it, but it does allow for generic nameplate creation. Said.Good informative post i love to read.

Leaking pumps, valves and seals cause many problems, leading to wastage, poor performance, unnecessary costs, even health hazards. Kemet Portable Lapping Kits enable refurbishment to be carried out on site, reducing expensive downtime. Components manufactured from ceramics, tungsten carbide, stellite, brass, steel, silicon carbide, carbon, ni-resist etc, can be lapped and/or polished by hand in minutes rather than hours. The kits are also ideal for low volume production, where it is not economical to purchase a lapping or polishing machine.
