Introduction of the manufacturing process and weighing method of stainless steel decorative tube

- Jan 10, 2021-

The stainless steel decorative pipe is a stainless steel pipe made by welding a steel plate or a steel belt through a unit and a die. Let's take a look at the process flow of the stainless steel decorative tube with the small series.

Manufacturing process and process of stainless steel decorative tube: steel plate → slitting → forming → melting → induction bright heat treatment → internal and external weld bead treatment → shaping → sizing → eddy current detection → laser diameter measurement → pickling → storage.

Advantages and disadvantages of stainless steel decorative tubes :
First, the product 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;

Second, the process of the product determines its advantages and disadvantages. Generally, the welded steel 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.

Stainless steel decorative tubes are widely used as pipes for conveying fluids, such as petroleum, natural gas, water, gas, steam, etc. In addition, when the bending and torsional strength are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering. structure. Also used to produce a variety of conventional weapons, barrels, shells and so on.

304, 201 stainless steel decorative tube round tube weight formula:

(outer diameter - thickness) x thickness x0.02491

Such as a 38x2 size round tube:


304, 201 stainless steel decorative pipe square tube weight formula:

(side width x4÷3.14-thickness) x thickness x0.02491

Such as 40x40x2 size square tube:


304, 201 stainless steel decorative tube rectangular tube weight formula:

((length + width) x2 ÷ 3.14-thickness) x thickness x0.02491

For example, a 40x20x2 rectangular tube:
