DSAW steel pipe - COSASTEEL

ERW pipes are used to transport water, gas, air, oil, and heating steam, suitable for low and medium pressure fluid pipes, and structural steel pipes. DSAW straight seam steel pipes are used in supporting facilities such as large-span grid engineering, water gas pipelines, construction, power engineering, machinery, bridge beams, steel structures, and foundation piling. LSAW steel pipeLSAW/EFW Structural Pipe. LSAW/EFW steel pipe:Standard:ASTM A139, ASTM A252, JIS G3444 etc. Grades:Q215-345, Grade A-E, Grade 1-3 STK290-540 Used as low pressure liquid delivery pipes,variety of structural parts by the force and pressure as we. LSAW Coating Pipe Spiral Welded Tube Machine - steel pipe machines Spiral welded pipe machine is used to big diameter pipes by spiral welding method. By decoiler to uncoil and level the steel coil, and send the strip to forming machine by certain angle, then bend the pipe by certain angle based on three-roller forming principle, at last weld the spiral welding seam by the submerged arc welder.

Low temperature steel pipe refers to the steel pipe used in low temperature environment below -10. The steel usually used at low temperature of -10~-196 is called low temperature steel, and the steel used at low temperature below -196 is called ultra-low temperature steel, which has enough notch toughness.

Tube Mill, Pipe Mill Machine, Steel Pipe Making Machine

Tube Mill machine main equiment includes double cone decoiler (hydraulic expansion and contraction), automatic cutting & butt welding (pneumatic cutting), horizontal looper, forming and sizing unit, Hot grinding computer saw, Output roller, Roll (optional or prepared by buyer), cutting system, etc.Steel pipe making machine can produce welded tubes of different specifications (pipe diameter Types and process of welding pipe-ERW,LW,CW,SAW pipes ERW including high frequency welded steel pipe(HFW) and low frequency welded steel pipe(LFW).Over time, the welds of low frequency ERW pipe was found to be susceptible to selective seam corrosion,hook cracks,and inadequate bonding of the seams,so low frequency ERW is no longer used to manufacture pipe.The high frequency process is still being used to manufacture pipe for use in new pipeline Welded Pipe & Tube Manufacturer in ChinaSSAW Pipe, SAWH Pipe, Spiral Steel Pipe.
