Shandong Kuaima  Steel Co., Ltd.



Electrical Resistance Welding Stainless Steel Tube Dealer


Product introduction

Product characteristics

ERW stainless steel pipe due to the use of hot rolled coils as raw material, wall thickness can be uniformly controlled to ± 0.2mm, steel pipe according to the maintenance end of the beveled fixed length delivery. US APl standard or GB/T9711.1 standard at the second end.
Used for the transport of oil, natural gas and other steam, liquid objects, can meet a variety of high and low pressure requirements, in the world of pipeline transport occupies a pivotal position.

Stainless steel welded pipe, referred to as welded pipe, commonly used steel or steel strip after the unit and mold curling forming welded steel pipe. Welded steel pipe production process is simple, high production efficiency, a variety of specifications, less investment in equipment, but the strength is generally lower than seamless steel pipe.

Since the 1930s, with the rapid development of high-quality strip steel continuous rolling production and the progress of welding and inspection technology, the quality of the welded seam continues to improve, the increasing variety of welded steel pipe specifications, and in more and more areas, especially in the heat transfer equipment, decorative tubes, low-pressure fluid tubes instead of seamless steel tubes.

Product characteristics:

One, small diameter stainless steel welded pipe is continuous online production, the thicker the wall thickness, the greater 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; secondly, the process of the product determines its advantages and disadvantages, general welded 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 reflects its economy and beauty in high-precision, low and medium pressure fluid applications.

Welding Characteristics:

According to the welding process can be divided into automatic welding welding, manual welding. Automatic welding generally uses submerged arc welding, plasma welding, manual welding generally uses argon arc welding.

According to the form of welding seam is divided into straight seam welded pipe and spiral welded pipe.

According to the use is divided into ordinary welded tube, heat exchanger tube, condenser tube, galvanized welded tube, oxygen blowing welded tube, wire casing, metric welded tube, roller tube, deep well pump tube, automobile tube, transformer tube, electric welding thin wall tube, electric welding shaped tube and spiral welded tube.

GB/T12770-2002 (stainless steel welded steel pipe for mechanical structures) is mainly used for mechanical parts and structural parts of machinery, automobiles, bicycles, furniture, hotel and restaurant decoration. Its representative materials are 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, etc.

GB/T12771-2008 (stainless steel welded steel pipe for fluid transportation) Mainly used for the transportation of low pressure corrosive media. Representative materials are 06Cr19Ni10, 022Cr19Ni10, 06Cr19Ni110Ti, 00Cr17, 0Cr18Ni11Nb, 06Cr17Ni12Mo2, etc.

Weight calculation formula.
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
