The company specializes in the research and development, production and sales of P295GH equivalent grades seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has p295gh equivalent grades five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,p295gh equivalent grades rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.

The Cr-Mo alloy steel pipe fittings manufactured to ASTM A234 includes the grades of WP1, WP12 CL1, WP12 CL2, WP11 CL1, WP11 CL2, WP11 CL3, WP22 CL1, WP22 CL3, WP24, WP5 CL1, WP5 CL3, WP9 CL1, WP9 CL3, WP91, WP911, WP92. The BW pipe p295gh equivalent grades fittings can be made from either seamless pipes, or fusion-welded pipes which shall be with filler metal added and shall conform to the chemical requirements of the standard specification.

4140 steel is alloy structural steel, and its technical standard is ASTM A29/A29M. It belongs to ultra-high strength steel. p295gh equivalent grades, 4140 steel has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after tempering treatment, and good low temperature impact toughness. 4140 steel is suitable for manufacturing large and medium plastic mould with certain strength and toughness.

The effect of nitrogen (N) on the properties of p295gh equivalent grades and so on steel is similar to that of carbon and phosphorus. With the increase of nitrogen content, the strength of steel can be significantly improved, especially the plasticity, especially toughness, and the weldability will be decreased, and the cold brittleness will be intensified. At the same time, aging tendency, cold brittleness and hot brittleness will be increased, which will damage the weldability and cold bending property of steel. Therefore, the nitrogen content in p295gh equivalent grades and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.
