API N80-1 Seamless Casing Pipe with BTC threads N80 Seamless Casing Pipe includes N80-1 and N80-Q steel grades. These 2 grades are the same in both of chemical composition and mechanical properties. The only difference is the Heat Treatment. The latter one N80-Q steel pipe requires heat treatment before they are to be manufactured into casing pipes.

Plain End Oil Well Seamless Casing Pipes is different from the Threaded & Coupled Seamless Casing Pipes when it comes to ends of the pipes. The former one is plain end, while the latter one is threaded as BTC, STC or LTC with couplings attached. But they are all manufactured according to API 5CT standard. Customers always have their choices based on the specific conditions such as total cost, import policy, processing methods etc Details of Plain End Oil Well Seamless Casing

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,

OCTG --Pup Joints (Casing & Tubing pup joints) A pup joint is a pipe of non-standard length used to adjust the length of tubular strings to its exact requirement. Tubing/Casing Pup Joint 1) Size: 2-3/8 inch to 4-1/2 inch 2) End Type: NU & EU 3) Steel Grade: H40,J55, K55, N80, L80, P110 Q125 4) Specification: API Spec5CT; 5) Feature: Nanoscale Titanlum-containing Compound Coated, high corrosion resistance and long running life. 6) Dimensions and their tolerances of tubing

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.

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. Standard: API SPEC 5CT.

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.

Left Hand Thread is a special connection, which is opposite to Battress Thread Connection.

A thread protector is used to protect the threads of a pipe during transportation and storage. Thread protectors are generally manufactured from plastic or steel and can be applied to the pipe manually or automatically (by machine). Thread protectors are used frequently in the oil and gas industry to protect pipes during transportation to the oil and gas fields. Metal thread protectors can be cleaned and re-used, while plastic thread protectors are often collected and either
