【Frequently Asked Questions】

What is spiral welded pipe gost standard?

Spiral welded pipe gost standard is a spiral seam welded steel pipe produced in accordance with the Russian state standard (GOST), which is made by spiral forming and welding of steel strips.

What fields are spiral welded pipe gost standard applicable to?

Spiral welded pipe gost standard is applicable to long-distance oil and gas pipelines, urban water supply and heating pipelines, large steel structure support and other projects.

How does the GOST standard ensure the corrosion resistance of spiral welded pipes?

Spiral welded pipe gost standard requires surface anti-corrosion treatment, such as polyethylene coating, coal tar enamel, etc.

What are the restrictions on the dimensional tolerance of spiral welded pipes in the GOST standard?

The allowable deviation of pipe diameter is ±1%, the wall thickness deviation is ±0.5mm - ±1.2mm, and the length deviation is ±20mm.

What are the requirements for the packaging and transportation of spiral welded pipes in the GOST standard?

Spiral welded pipe gost standard should be packaged by bundling, bracket fixing and other methods to prevent collision and deformation during transportation. Long-distance transportation requires moisture-proof and anti-corrosion protection, and the goods must be stacked according to different specifications, and accompanied by quality certificates and test reports.
