Weight Calculation Method

Considering that the components of SS 304 and SS 316 are different, their weights are also different. Here are the computational formulas.

(diameter – wall thickness) * wall thickness * 0.02491 * length = weight (kg)

(diameter – wall thickness) * wall thickness * 0.02513 * length=weight(kg)

If you want to estimate the weight of your cargo, you can calculate it by this formula. Feel free to contact Wanzhi Steel for any other questions.

What Is Stainless Steel Welded Pipe?

Stainless steel welded pipe is a kind of welded pipe, which is made of stainless steel or steel strip that is welded after being rolled and formed by a unit and mold. It has a simple production process, high production efficiency, and many varieties and specifications. However, its general strength is lower than that of seamless steel pipe.

Production Process

Raw material inspection → Splitting → Shaping → Welding → Cutting → Heat treatment → Straightening → Plane end → Eddy current flaw detection → Hydrostatic test → Internal polishing → Outer polishing → Terminal test → Delivery

Benefits of Stainless Steel Welded Tube

1. Anti-rust

Stainless steel welded pipe has nickel, manganese, iron, carbon, and silicon as components. The most critical of these is chromium. Most welded tubes made from stainless steel contain about 10.5% chromium, which is highly resistant to rust and water.

2. Uniform Wall Thickness

Stainless steel welded pipe is welded after being rolled and formed by a machine and a mold and has a uniform wall thickness. In addition, it can be made to any size. This means that it can also meet the different requirements of your project for size.

3. Environmentally Friendly

Stainless steel consists of at least 65% recycled material. Discarded stainless steel welded pipes can be recycled into new steel products. This makes stainless steel welded pipe a very environmentally friendly choice.

4. Long Life Span

Compared to various other types of steel and metal pipes, stainless steel welded pipes have a much longer service life. In general, stainless steel piping can last for about 70 years. That’s why you’ll typically find it in many commercial and domestic kitchens.

5. Beautiful Appearance

Stainless steel welded tube is subjected to uniform extrusion during the production process, and then the solid solution is annealed, the surface becomes very smooth. In addition, it has a high brightness inside the tube. When it is used in urban landscape or architecture, it is very ornamental.

Is It Safe to Weld Stainless Steel Water Pipes?

When it comes to drinking water pipes, we usually consider their safety. So is welded stainless steel plumbing safe?

Obviously, it is safe. Stainless steel welded pipe is a very energy-saving and environmentally friendly product. When it is used for water pipe, it does not become brittle at low temperature and has good heat preservation performance at high temperature, so it does not cause energy waste when conveying hot water. Moreover, the internal surface of stainless steel welded pipe is smooth, clean and hygienic. Compared with other water pipes, such as galvanized pipes and plastic pipes, welded stainless steel water pipes are the best choice for transporting drinking water and general household water.
