304 stainless steel welded steel pipe referred to as 304 stainless steel welded pipe, commonly used stainless steel plate or steel strip through the unit and die crimped after forming stainless steel welded pipe.

---

Introduction

304 stainless steel welded pipe has simple production process, high production efficiency, many varieties and specifications, and less equipment, but the general compressive strength is lower than stainless steel seamless steel pipe.

 

In recent years, with the rapid development of high-quality stainless steel strip continuous rolling production and the advancement of stainless steel welding and inspection technology, the quality of welded joints has been continuously improved, and the variety specifications of welded stainless steel tubes are increasing, and in more and more fields. It replaces the stainless steel seamless steel pipe in the exchange of heat exchangers, decorative pipes, medium and low pressure fluid pipes.

 

Characteristics

 

1. The small-diameter 304 stainless steel welded pipe is continuously produced online. The thicker the wall thickness, the greater the investment of the unit and the welding equipment, the less economical and practical it is. The thinner the wall thickness, the lower the input-output ratio will be;

 

2. The process of the product determines its advantages and disadvantages. Generally, the 304 stainless steel welded pipe has high precision, uniform wall thickness, high brightness inside and outside the pipe (the surface brightness of the steel pipe determined by the surface grade of the steel plate), and can be arbitrarily fixed. Therefore, it demonstrates its economy and aesthetics in high-precision, medium- and low-pressure fluid applications.

 

Use

 

GB/T12770-2002 (stainless steel welded steel pipe for mechanical structure).

Mainly used in machinery, automobiles, bicycles, furniture, hotel and restaurant decoration and other mechanical parts and structural parts. It represents materials 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, and the like.

 

GB/T12771-2008 (stainless steel welded steel pipe for fluid transportation).

Mainly used to transport low pressure corrosive media. Representative materials are 06Cr19Ni10, 022Cr19Ni10, 06Cr19Ni110Ti, 00Cr17, 0Cr18Ni11Nb, 06Cr17Ni12Mo2 and the like.

 

Calculation formula

 

304 stainless steel welding management theory weight calculation formula per meter weight:

M/kg=(outer diameter-wall thickness)xwall thickness x0.02491
Unit: outer diameter mm, wall thickness mm, weight kg
