ASTM JIS Stainless Steel Welded Pipe Large Diameter For Industrial Fluid Conveying
Description
Welded stainless steel pipe referred to as stainless steel welded pipe, commonly used steel or steel band after the unit and mold crimp forming of the steel pipe.Welding steel pipe production process is simple, high production efficiency, variety and specification, equipment investment is less, according to the welding form divided into straight welded pipe and spiral welded pipe.It can be divided into general welded pipe, heat exchanger pipe, condenser pipe, galvanized welded pipe, oxygen-blown welded pipe, wire bushing, metric welded pipe, roller pipe, deep well pump pipe, automobile pipe, transformer pipe, welded thin-wall pipe, welded special-shaped pipe and spiral welded pipe
Large diameter welded pipes generally adopt double-face submerged arc welding process, which can be divided into large-mouth straight seam welded pipes and large-diameter spiral welded pipes according to the different welding seams. The straight seam pipes can be divided into UOE, RBE and JCOE steel pipes.
According to the different forming methods.Mouth straight seam welded pipe production technology is simple, high production efficiency, low cost, and the intensity of large diameter spiral welded pipe generally higher than the straight seam welded pipe, large diameter welded pipe is mainly used in large water conveyance pipeline engineering, gas engineering, urban pipe network construction, municipal engineering, water supply and drainage engineering, large steel structure construction, pile foundation and so on.The main detection method of large diameter welded pipe is flaw detection.
HAOSTEEL is one of the most professional manufacturer and supplier of stainless steel welded pipe. Stainless steel pipe can be divided into seamless pipe and welded pipe. Aaccording to production mode, seamless pipe can be divided into hot rolled pipe, cold rolled pipe, cold drawn pipe and extruded pipe.The welded pipe is divided into straight welded pipe and spiral welded pipe.
