Line Pipe

What is natural gas pipe line seamless line pipe X52NS?

Seamless line pipe X52NS is one kind of natural gas pipe line pipes which are connected by welding, coupling, socket and spigot, etc. The line pipe X52NS produced by domestic steel manufacturers are used to pump oil, steam and water from the ground to oil and natural gas industrial enterprises through pipeline pipes. Line pipes include seamless pipe and welded steel pipe, with flat end, threaded end and socket end at the pipe ends. API 5L pipeline seamless steel pipe, the material refers to GR. B, X42, X46, 52, X56, X60, X65, X70 and so on. The connection methods are welding, coupling connection, socket connection, etc.

The material analysis you should know about line pipe

The material of line pipe belongs to low carbon or ultra-low carbon microalloyed steel, which is a product with high technology and high added value. The production of line pipe has almost applied all the new technological achievements in the metallurgical field in the past 20 years. The development trend of line pipe engineering is large pipe diameter, high pressure rich gas transmission, high cooling and corrosive service environment, and thickening of submarine pipelines. Therefore, the line pipes should have high strength, low bauschinger effect, high toughness and resistance to brittle fracture, low carbon content and good weldability, as well as resistance to HIC and H2S corrosion. The production strategy is to improve the cleanliness and structure uniformity of steel, C ≤ 0.09%, S ≤ 0.005%, P ≤ 0.01%, O ≤ 0.002%, and to adopt microalloying, vacuum degassing+CaSi, light reduction in continuous casting process, multi-stage thermo mechanical rolling and multi-functional intermittent accelerated cooling processes.

Natural gas pipe line seamless line pipe X52NS is just such line pipe has good performance of anti-corrosion and mechanical property which can be used for sour environment. Since the low contents of sulphur and phosphorous, line pipe X52NS can pass HIC ans SSC tests. Only the pipes are qualified if passed the two tests, otherwise they should not be agreed to use in the sour environment.
