API 5L X70 Pipe
API 5L X70 contains two product specification levels: PSL1 and PSL2. API 5L X70 pipe is known for its non-combustibility and at the same time, it also has high corrosion resistance. API 5L Gr X70 covers both seamless and welded (ERW, SAW) types of fabrication, and the products covered are all suitable for oil and gas transmission.

What’s The Difference Between API X42 And X52 Pipe?
API 5L X52 steel is a steel grade commonly used in the petroleum industry, it is a higher strength steel grade than X42 and is often used in high pressure applications. X42 and X52 pipes are widely used in oil and gas industries. Each grade of API 5L X42 line pipe and API 5L X52 line pipe (seamless and welded) has two product specifications, PSL1 and PSL2. This article will talk about the differences between them.

Differences Between Casing Coupling And Tubing Coupling
Commonly, OCTG couplings can be divided into casing couplings and tubing couplings. The function of casing couplings and tubing couplings is the same that to connect the pipeline each other. However, there are still some differences between the two.

Types of Pipe Couplings
Pipe couplings or couplers are important components that connect pipelines while maintaining the integrity of the pipes. Pipe couplings have socket or female pipe threads at one or both ends, and are used to connect pipe sections of equal or different diameters.
