Shanghai Metal Corporation is a leading welded stainless steel pipe manufacturer and supplier.

  • Stainless steel welded pipe, referred to as welded pipe, commonly used steel or steel strip is welded by the unit and the mold after crimp forming. The welded steel pipe has simple production process, high production efficiency, many varieties and specifications, and low equipment investment, but the general strength is lower than that of seamless steel pipe.

  • Since the 1930s, with the rapid development of high-quality strip continuous rolling production and the advancement of welding and inspection technology, the quality of welded joints has been continuously improved, and the variety specifications of welded steel pipes are increasing, and in more and more fields, especially in The seamless steel pipe was replaced by tubes for heat exchange equipment, decorative tubes, and medium and low pressure fluid tubes.

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.


Packaging of Stainless Steel Tubes/Pipes:

All our products are guaranteed to be packed, stored and transported according to the highest international regulations. We care deeply about the quality of our products down to even the smallest detail. We wrap all stainless steel products with anti-rust paper and steel rings to prevent damage. Our storage racks are made of wood and other kinds of metals are placed in other places, far from the stainless steel. Any unwanted chemical reaction can be prevented. Identification labels are tagged according to standard specification or customer's instructions. Special packing is also available as per customer's requirement.


Applications of Welded Stainless Steel Pipes/Tubes:

1. Petroleum, Chemical enterprise, super heater of boiler, heat exchanger

2. High temperature resistant transmission fluid pipe in power station

3. Ship with pressure pipe

4. The exhaust purification device

5. Construction and ornament



Q: Can you do polished finish for the tubes/pipes?

A: Yes, for welded tubes/pipes, we can do mirror polishing, 600# polishing, 500# polishing, 320# polishing, 240# polishing and so on, brushed finish is also available. For seamless tubes/pipes, normally the surface is pickled finish, while brushed finish is also doable.

Q: What’s your standard package?

A: Our standard package is waterproof plastic bags with wraps. For advanced packing, we can provide round paper tube for each tube, and wooden/metal case for exterior packing.

Q: Where’s your main market?

A: South America, Mid-east, South-east Asia, Europe and so on.

Q: Do you also have the accessories for the tubes?

A: Yes we can provide the accessories too.

Q: What length is your standard length? Can I have the tubes/pipes cut into the length I want?


A: Our standard length is 3meter, 4meter, 5meter, 6meter. If you length is less than 3meter, we will have to run an additional processing for cutting which will bring some more costs. The minimum length is 500mm. For seamless tubes, we can make maximum to 12, 13meters.
