Large Diameter Steel Pipe Ssaw Steel Pipe Astm A252 Gr.3 Standard Welded Carbon Steel Pipe

Spiral steel pipe is mainly used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction, is one of 20 key products of our country's development.
For liquid transportation, water supply and drainage.For gas, gas, steam, liquefied petroleum gas.For structure: piling pipe, bridge;Dock, road, building structural tube, etc.

Steel grade can be gr.2,gr.3 Q235A,Q235B,10#,20#,Q345(16Mn),L245(B),L290(X42),L320(X46),L360(X52),L390(X56),L415(X60),L450(X65),L485(X70),L555(X80),L290NB/MB(X42N/M),L360NB/MB(X52N/M),L390NB/MB(X56N/M),L415NB/MB(X60N/M),L450MB(X65),L485MB(X70),L555MB(X80.

While under the influence of economic crisis, but the spiral steel tube company is recovering gradually development, to meet a better tomorrow.Spiral steel pipe in gas transmission, transportation plays a large role.
With several major pipeline engineering planning and construction at home and abroad, the large deformation of pipeline steel, high strength thick low temperature level roasted bend and pipe fittings for high-value-added products, showing good market competition ability and large market demand, and domestic enterprises in the development of this series of products progress slowly.As soon as possible in order to develop suitable for industrial application of high added value of large deformation of pipeline steel, roasted bend pipe steel, pipe yard with low temperature pipes with steel, X100 straight seam submerged arc welding pipe, spiral seam submerged arc welding pipe and roasted bend, spiral steel pipe.
