Steel Pipe For Atmospheric And Lower Temperatures

Low & Ambient Temperature Service JCOE LSAW Steel Pipe

Product Brief Introduction

This series pipe belongs to LSAW longitudinal submerged arc welded pipe, which is the core material for constructing high-strength long-distance oil & gas transmission pipelines with strict quality standards. For large-scale oil and gas transmission projects passing through alpine cold zones, seabed laying sections and densely populated urban areas, this low-temperature resistant LSAW pipe is the exclusive matching pipe grade specified by API industrial standards.

Core Product Advantages

The pipe adopts full longitudinal weld design, with both inner and outer weld seams finished by double-sided submerged arc welding process. Every finished pipe goes through integral mechanical expanding calibration after welding molding, which minimizes residual internal stress inside tube bodies and distributes stress evenly across the whole wall, effectively inhibiting stress corrosion cracking risk under low-temperature complex service environments. The production line supports an extremely wide specification range, capable of manufacturing both thin outer diameter heavy wall pipes and large-diameter thick-wall pipes to meet diversified engineering demands.
