EN 10219/S235 Welded steel pipes
European standard cold-formed welded structural hollow steel, S235 is a low-carbon mild steel grade, cold-formed and welded, with excellent weldability and economical cost.
Spiral submerged arc welded pipe (SSAW)
Made from hot-rolled steel strip coils, spiral-formed and double-sided submerged arc welded, the weld seams are distributed in a spiral pattern, suitable for large-diameter medium and low-pressure pipelines, offering high cost-effectiveness.
Straight seam submerged arc welded pipe (LSAW)
Made from steel plates, formed using UOE/JCOE technology and double-sided submerged arc welding, with a single straight weld seam, and subjected to water pressure and diameter expansion treatments, resulting in high dimensional accuracy and strong pressure resistance.
High-frequency resistance welded straight seam steel pipe utilizes the skin effect to melt the steel strip edge and apply pressure during welding.
The steel pipe surface is treated with hot-dip galvanizing or electro-galvanizing to form a zinc-iron alloy protective layer, which has a dual anti-corrosion effect of physical barrier and electrochemical cathodic protection.
The American Petroleum Institute (API) line pipe standard is the mainstream specification for global oil and gas pipelines.
The American Petroleum Institute Oil and Gas Industry Casing and Tubing Standard (OCTG) is used for oil and gas wellbore construction, and is available in multiple steel grades and thread types to withstand the high-pressure and corrosive environment downhole.
