Description Technical Information Packaging More Review

Guangdong Metal Corporation is a professional manufacturer and supplier of Stainless Steel Tube, Stainless Steel Pipe with high quality and reasonable price.

Stainless Steel Pipe is a hollow strip of round steel, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components. 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 structures. Also used as furniture and kitchenware.Steels that are open at both ends and have a hollow section, and whose length is larger than the circumference of the section, can be called steel pipes. When the length is small compared to the perimeter of the section, it can be called a pipe section or a tubular fitting, which are all in the category of pipe products.

Manufacturing Process of Stainless Steel Pipes/Tubes:

The process commences with the formation of welded mother tube on the tube mill from imported and tested prime quality stainless steel strips. The latest TIG multi electrode welding technique is employed for superior weld quality and 100% Fusion, with argon purging, No filler metal added.

The production process of stainless steel tubes and pipes involves several steps, including melting, casting, rolling, welding, annealing, and finishing. Let's take a closer look at each step:


1. Melting: The raw materials, including scrap metal and alloying elements, are melted in an electric arc furnace or induction furnace.


2. Casting: The molten steel is poured into molds to create billets, which are then reheated and rolled into thin sheets.


3. Rolling: The sheets are rolled into tubes and pipes of various sizes and thicknesses using either a seamless or welded process.


4. Welding: For welded tubes and pipes, the edges of the rolled sheets are heated and fused together using a high-frequency welding process.


5. Annealing: The tubes and pipes are heated to a high temperature and then cooled slowly to relieve internal stress and improve ductility.


6. Finishing: The tubes and pipes are cut to size and finished according to customer requirements, such as polishing, buffing, or painting.


Throughout the production process, strict quality control measures are in place to ensure the products meet international standards, such as ASTM, DIN, and JIS.
