Starting from Macaroni sizes up to heavy wall test strings and with different connections we offer a huge range of specifications. What is a Pup Joint? Pup Joints are shorter versions of tubing and casing, used to adjust the length of a string to its" exact requirements. There are many different cases where Pup Joints are necessary: to reach an exact reservoir depth, for setting packers at an exact location within the borehole, to space out your string prior to hanging it and many more. What are the benefits? Pup Joints are a mandatory party of equipment in almost any well. Due to their shorter length, they are typically easier to handle and to use. At the same time, they provide the same performance as the tubing/ casing/drill pipe that they are attached to. TPS Pup Joints have a lot more advantages beyond that.

API Coupling refers to the steel couplings that used in connecting casing pipe and tubing. Also known by OCTG coupling, it is usually manufactured in seamless type, material grade same with the pipe body (API 5CT K55/J55, N80, L80, P110 etc), same PSL or providing higher grades than requested. Same heat treatment also applicable, except there is an special requirements.

With this purpose, API 5CT standard coupling plays an important feature in connecting casing and tubing line pipes. On the contrary, the biggest different with general steel pipe coupling is: API coupling manufacturing processes is more rigorous, requires a precisely control in the different processes as blew listed.

As we told, one of the important figure of API coupling, that it shall be made of seamless, another is the same grade as the casing or tubing pipe body, and these materials are used for manufacturing the blank coupling.

In case purchase order did not specified heat treatment types, J55/K55 casing or tubing coupling shall be furnished either in as rolled, normalized, normalized and tempered, or quenched and tempered.

Mechanical properties of casing or tubing coupling shall comply to the clauses 7 and 10, covers test frequency, retest provision, etc. And this test records could be shown to third party inspector assigned from the client.

There are several types covered in API 5CT standard for coupling specifications, classified in regular couplings, special clearance couplings, combination couplings, reducing couplings, seal ring couplings, and special bevel tubing regular couplings.

In case specified in the contract, special-clearance (reduced outside diameter Wc) couplings for buttress (BTC connection) casing and external upset (EUE connection) tubing shall be furnished. Unless otherwise specified, special-clearance external upset tubing couplings shall have a special bevel on both ends. The inside and outside edges of the bearing face shall be rounded or beveled. The ends (or root face when beveled) of couplings shall be faced at right angles to the axis.

There are couplings for casing and couplings for tubing, the function is the same that to connect the pipe each other. On the other hand, still there are some differences between the two.

Normally tubing coupling OD maximum is 4 1/2”, as the tubing pipe is applied for the drilling activities (Inside the tubing is the sucker rod to drill/pump the oil), couplings type is more various and rigorous than casing, mostly used is thicken type upset coupling (Internal upset and external upset), for short is EUE coupling, it is the most favorable in tubing connections. Tubing with EU end (EUE) coupling connection also called UPTBG. Because of the end of the tubing is thickened (upset), the connecting stress is better than buttress coupling.

The oil tubing coupling can solve the problem of fatigue fracture in the existing coupling due to stress concentration. Oil tubing end is connected to the inside wall of the coupling in a tapered thread. The coupling body end and oil tubing are connected with same thread pitch flat thread. The coupling is not easy to produce fatigue fracture, and has good connection effect. It can prevent the accident of oil well pipe string break effectively.

Casing coupling is for the dimensions more than 4 1/2 inch. Differently than tubing coupling is, casing coupling normally does not need to be thickened (Non-upset), which means no upset casing coupling, so it has following types:

The oil casing coupling is a necessary piece used to connect the two casing. The coupling manufacturing method is the same as seamless pipe. The steel pipe ends with internal thread to connect with the upper and lower casing. In order to ensure the joint tightness, the precision of screw thread is strictly required.

API 5B covers dimensions, tolerances, and marking for API threads and the gauges that control the acceptance criteria for the threads. It includes thread element gauges, instruments, and requirements for the inspection of threads for line pipe, casing and tubing (round threads), and buttress casing connections. Thread dimensions shown without specifications (or shown as NA) are not subject to inspection of diameter, ovality, and addendum. Thread dimensions shown without tolerances are related to the basis for connection design and are not subject to measurement to determine acceptance of product.

Premium connection is a higher class connection type for used to connect casing or tubing pipelines. The reason to use premium connection is due to it’s high seal performances, high strength, and longer durability.

API casing and tubing coupling dimension ranges from OD 1.05 inch to 20 inch (26.7 mm to 508 mm), wall thickness normally ranges from 0.16 inch to 1 inch (4.2 mm to 22 mm).

Tests for making couplings is similar with the casing and tubing, which includes: Tensile test, flattening test, hydrostatic pressure test, sulfide stress corrosion cracking test, grain size determination, transverse impact test and hardness test.
