Both offer eight or ten round threads per inch and a non—runout design of round threads. NUE is well suited to light duty, general purpose applications. EUE can be deployed for general purpose drilling and production applications where internal pressures are moderate. Tubing and casing threading services encompass bucking, torque turn, saw cutting, and full-length drift. We provide threading through U. Casing Pipe The shape of the casing section is round, in large diameter pipes and is inserted into the oil well, fixed with cement to protect other equipment that is mostly made of iron and steel.

The oil well must be designed to withstand the force different from the external power, such as crushing, explosion, stress and chemical corruption. API 5CT casing pipe is used to support the oil and gas pipe wall, and to ensure the drilling process and the post-completion wells normal operation. Each well depending on the depth of drilling and geological conditions, to use several layers of casing.

After cementing casing to be used to go down, it different from tubing, drill pipe and can not be reused, a one-time consumable materials. According by usage can be divided into the sleeve pipe, surface casing, casing and production casing. Tubing is the simplest part of OCTG and it is normally found in the segment of 30 ft 9 m , with threaded connection at both ends. The pipe is either used to transport natural gas or crude oil from the producing formation to the facilities where it will be processed after drilling is complete.

The pipe is either used to transport natural gas or crude oil from the producing formation to the facilities where it will be processed after drilling is complete.

Tubing pumping pipe goes inside the casing because it is the pipe through which oil makes its way out. Pipe of production is the simple part of OCTG and it is normally found in the segment of 30 ft 9 m , with threaded connection at both ends.

The API coupling plays an important role in the connection of pipes and casings, since it requires more rigorous manufacturing processes than normal steel couplings. The recommended standard is API 5B. Our advantages Sourcing from all the good API 5CT casing pipe manufacturers in China, Enpro is working on providing high quality casing pipe with most competitive price.

BTC Buttress threading This thread is designed to improve axial tensile or axial compressive load capacity and to provide leakage resistance. Connection strength and tightness are two main coupling technical indicators. Both LTC and STC couplings in generally use lead, zinc, copper, graphite or silicone oil composition to improve seals, but those seals only work under temperature of Celsius. Also for STC coupling, if under huge external pressure and axial tensile stress, when heavy impact or bent happens, the threading will have more chance to slippage.

Both of those two type of threading are not suitable for heavy oil thermal recovery, ultra-deep well and heavy corrosion environment. API standard threading coupling primarily seal the pipe by thread grease, metal plating and thread engagement of interface. STC thread root to tip clearance is 0.
