Oil Tubing is pipe used for the transportation of crude oil and natural gas from an oil or gas layer to the surface after drilling is complete. It is made to withstand the pressure generated from the extraction process. Tubing is manufactured in the same way as casing, except that an additional process known as "upsetting" is applied to thicken the pipes. Descriptions: 1 Production Process: Seamless & ERW 2 Specification: API 5CT /5B 3 Out Diameter: 2 3/8" - 4 1/2" (60.3m

Seamless Casing Pipe is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells, or well bore. It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing and to allow drilling fluid to circulate and extraction to take place. Steel Casing Pipes have smooth wall & minimum yield strength of 35,000 psi. Details: Standard: API 5CT OD: 4-1/2'-----20' Material: H40, J55, K55,

The external upset end (EUE) API tubing uses taper pipe with round thread. It realizes connection and seal through the joint upsetting. After the thickening of both ends, heat treatment, thread processing, and installing of the coupling and thread protector are carried out in order. The EUE API tubing has two main features. Without changing the thread shape, the joint size increases through the upsetting process. This leads to a substantial increase in the connection strength

Perforated screen casings refer to a hole punched in the casing or liner of an oil well to connect it to the reservoir. Creating a channel between the pay zone and the wellbore to cause oil and gas to flow to the wellbore easily.

K55 API seamless casing pipe or tubing pipe is similar to J55 . They stay the same in chemical composition and yield strength; however, the tensile strength of K55 is higher than J55 grade. They are almost the same when it comes the price and applications. Generally, customers prefer to K55 when the casing pipes are to be used in water wells.

N80 Casing Couplings from Borun pipe company : API coupling is an internally threaded cylinder for connecting two threaded pipes. It is an integral part of the tubing and casing. Each tubing or casing should be equipped with an API coupling. The casing with different thread types selects different types of this fitting. Therefore, the product is mainly divided into buttress thread and round thread types, which correspond to buttress and round thread casing respectively.
