1. Product specifications:

Diameter of steel pipe: 60-1402 mm

Thickness: 2.5-3.7 mm

Product Standards: SO3183, API 5LI, API 2B, GB/T9711, etc.

Output: annual output of 10,000 tons of large diameter straight submerged arc welded steel pipe

2. Use of multi-purpose straight seam welded steel pipe:

It is mainly used for transportation of oil and gas, coal slurry, ore slurry and other media on land and ocean, as well as for pipes for offshore platforms, power stations, chemical industry and urban building structures.

3. Main characteristics:

1. After the whole mechanical diameter enlargement treatment, the stress inside the steel pipe is small and uniformly distributed, which can effectively prevent stress corrosion cracking, with high dimensional accuracy, and is convenient for field welding construction.

2. The welding process is stable and the quality of welding seam is high by using the pre-welded finish welding process.

3. Weld seam is easy to realize non-destructive inspection in production process and field non-destructive inspection in use process.

4. Compared with non-straight welded pipe, the weld is shorter and the probability of welding defects is smaller.

5. The product specifications range is large. It can produce both small diameter and large wall thickness steel pipes.
