Dry!Do you know the cold knowledge about stainless steel welded pipe?

Stainless steel welded pipe, referred to as welded pipe, commonly used steel or steel strip after the unit and mold crimping forming welded steel pipe. Welded steel pipe has the advantages of simple production process, high production efficiency, many varieties and specifications and less equipment investment, but its general strength is lower than that of seamless steel pipe. According to the welding technology can be divided into automatic welding, manual welding. Automatic welding is generally submerged arc welding, plasma welding, manual welding is generally argon arc welding. First, the small diameter stainless steel welded pipe is continuous online production, the […]

Seamless steel pipe tips

Seamless steel pipe is a kind of long steel with a hollow section and no seams around it. The steel pipe has a hollow section and is widely used as a pipeline for transporting fluids, such as oil, Pipes for natural gas, gas, water and some solid materials, etc. Compared with round steel and other solid steel, steel pipe has the same bending and torsion strength and lighter weight, which is a kind of warp Economic section steel is widely used in the manufacture of structural and mechanical parts, such as oil drill pipe, automobile drive shaft, bicycle frame and […]

Spiral welded pipe

Advantages and disadvantages of spiral steel pipe

 Spiral steel pipe is a spiral steel pipe made of strip steel or coiled plate in a spiral shape, using double-sided submerged arc active welding to weld the inner and outer seams. It can be widely used in water, electricity, and chemical industries for the following reasons In professional production: just by changing the forming viewpoint, steel pipes of various calibers can be produced with the same width of strip steel, which is easy to adjust.   Because it is formed by successive twists and turns, the fixed length of the spiral tube is not restricted, and the length can be set […]

The advantages of seamless steel tube

Seamless steel pipes are pipes with round hollow cross sections that do not have seams. They are generally factory-made using hot working steel. One of the advantages of the pipes is its growing preference. Seamless steel pipes can sustain high pressure. Generally, in welded pipes, the points of welds are the weakest for sustaining pressure, in turn damaging the pressure resistance capability of the pipe. In contrast, seamless pipes are tougher and more pressure resistant.    Seamless steel pipes make it easy to calculate pressure ratings, as there is no need to be concerned about the quality of welding. These […]

Welded vs. seamless steel pipe

Seamless steel tube is made of round billet by hot rolling, cold rolling or cold drawing process. There is no seam on the tube body. The welded steel pipe is made of flat steel plate and has welds on the tube body.Including ERW tube, LSAW tube, SSAW tube. The difference between seamless steel pipe and welded steel pipe: 1. Differences in appearance Seamless steel tube is made of billet.The external surface defects of the billet cannot be eliminated by the hot rolling process and can only be polished after the product is finished.In thinning the wall, only part of the […]
