The stainless steel welded pipe is round, and the stainless steel welded tube can be round, square, rectangular, oval, hexagonal, etc.
Stainless steel welded pipe/tube, referred to as welding pipe/tube, commonly used stainless steel or stainless steel strip through the unit and mold curling and forming after welding made of stainless steel pipe/tube. Welded stainless steel pipe/tube production process is simple, high production efficiency, a variety of specifications, less investment in equipment, but generally lower strength than a seamless steel pipe/tube.
Since the 1930s, with the rapid development of continuous rolling production of high-quality strip steel and the progress of welding and inspection technology, the quality of the welded seam continues to improve, the increasing variety of welded stainless steel pipe/tube specifications, and in more and more areas, especially in the heat transfer equipment, decorative tubes, low-pressure fluid tubes instead of seamless steel pipes/tubes.
Simple production process, high production efficiency.
Small diameter stainless steel welded pipe/tube is continuous online production, the thicker the wall thickness, the larger the investment in the unit and dissolving equipment, the less economical and practical it is. The thinner the wall thickness, its input-output ratio will drop accordingly;
The process of the product determines its advantages and disadvantages, general welded stainless steel pipe with high precision, uniform wall thickness, high brightness of the tube appearance (the surface grade of the steel plate determines the surface brightness of the steel pipe), and can be arbitrarily sized. Therefore, it embodies its economy and beauty in high-precision, low and medium-pressure fluid applications.
According to the welding technology can be divided into automatic welding, manual welding. Automatic welding is generally used argon arc welding, submerged arc welding, plasma welding, manual welding is generally used argon arc welding.
Classification
According to the form of the weld seam is divided into straight seam welded pipe and spiral welded pipe.
According to the use of the general welded pipe, heat exchanger tube, condenser tube, galvanized welded pipe, oxygen blowing welded pipe, wire casing welded pipe, metric welded pipe, roller tube, deep well pump tube, automotive tube, transformer tube, electric welding thin-walled tube, electric welding shaped tube and spiral welded pipe
Stainless steel welded tubes for mechanical structures. It is mainly used for machinery, automobiles, bicycles, furniture, hotel and restaurant decoration, and other mechanical parts and structural parts. Its representative materials 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, etc.
Stainless steel welded steel pipe for fluid transmission. Mainly used for the transport of low-pressure corrosive media. Representative materials are 06Cr19Ni10, 022Cr19Ni10, 06Cr19Ni110Ti, 00Cr17, 0Cr18Ni11Nb, 06Cr17Ni12Mo2, etc.
Stainless steel welded pipe/tube is generally used to measure its hardness by Brinell, Rockwell, and Vickers hardness indicators.
Commonly used:
Material 304/304L (diameter - wall thickness) x wall thickness x 0.02491 x length = weight (kg)
Material 316/316L (diameter - wall thickness) x wall thickness x 0.02513 x length = weight (kg)
Unit: kg/m
