Overview
Pipeline steel plate are used to fabricate large diameter welded pipes which transport oil and nature gas, also name as pipe steel plate. Now more and more world's people focus on protecting our environment, the new clean energy nature gas is widely used through pipelines. These pipeline steel plates owned ability of resisting high pressure, atmospheric corrosion and lower temperature surroundings. API X120 offered from us had higher mechanical properties than international level.
