API5LX65Q line pipe is a seamless steel pipe used for gas, water, and oil transportation in the petroleum and natural gas industries.

ASTM A249 TP 304L stainless steel welded pipe is made of 304L stainless steel material. 304L stainless steel is a low-carbon version of 18-8 stainless steel and has good corrosion

ASTM A500 is the standard for welded steel pipes in the American Society for Testing and Materials standards.

Welding galvanized steel pipe is routine but hazardous work: the zinc coating burns off around the joint, can weaken the weld through porosity and releases toxic fumes. This articl

X42 is a low-to-medium pressure line pipe grade, and HFW is an efficient welding route for its production. This article explains the grade, the process, weld integrity and applicat

API 5L Grade B is a carbon steel line pipe grade supplied at PSL1 and PSL2 for low to medium pressure pipelines, water mains and general fluid transport. PSL1 limits carbon to 0.28

Q345A, Q345B, Q345C, Q345D and Q345E are different grades of low-alloy high-strength structural steel. Their main differences lie in some minor differences in chemical composition

A thick-wall longitudinally submerged arc welded (LSAW) pipe is an expensive, precisely manufactured asset, and most of its corrosion protection is decided in the short window betw

Plastic-coated steel pipes are steel-plastic composite steel pipes that use steel pipes as the base and are welded with a plastic anti-corrosion layer on the inner surface of the s

API X42 is one of the steel grades, which means that the steel pipe has certain mechanical properties and chemical composition and is suitable for specific conveying pressure and t

ASTM A252 covers welded and seamless steel pipe piles in three grades defined by minimum yield and tensile strength. This article sets out the grade requirements, the forming and w

S355 J0 spiral seam welded pipe is a steel pipe produced according to European standard EN 10219 or EN 10217 and is mainly used for structural purposes.
