Welded Steel Pipe Ssaw Steel Pipe Hollow Steel Pipe Gr.B X42 X52 Api5l Psl1

Spiral steel pipe is a steel strip coil plate of raw materials, often warm extrusion molding, with automatic double wire welding double-sided submerged arc welding technology with the spiral seam pipe.Spiral steel pipe will strip into welded pipe unit, the multichannel roll rolling, strip steel rolled up gradually, there is an open space form of round billet, adjust the quantity of the squeezing roller, make the weld gap control in 1 ~ 3 mm, and make joint flush on both ends.

Ssaw Steel Pipe Hollow Steel Pipe main technical characteristics:
A. forming process, the steel plate uniform deformation, residual stress is small, the surface does not produce scratches.Processing spiral steel pipe on the scope of the size of diameter and wall thickness is more flexibility, especially in the production of high grade thick wall tube, especially small and medium caliber thick wall tube has incomparable advantage over other techniques, can meet the requirements of users in the aspect of spiral steel pipe specifications more.
B. using advanced double-sided submerged arc welding process, can be in the best position for welding, is not easy to appear the wrong side and defects such as lack of penetration, welding, welding quality easy to control.
C. 100% quality inspections for steel pipe, make the whole process of steel pipe production are under effective detection, monitoring, effectively guaranteed the product quality.
D. the whole production line all equipment with the function of the computer data acquisition system networking, realize the data real-time transmission, by the central control room of the technical parameters in the process of production.

Steel grade can be 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.
