tips for spiral welded steel pipe

Straight seam welded steel pipe has simple processing, high production efficiency, low cost and rapid development. The strength of spiral welded steel pipe is generally higher than straight seam welded pipe. Usually adopting narrow billet can process larger diameter welded pipe. And you can also use the same width of billet to produce different pipe diameter welded pipes. Compared with the straight seam welded steel pipe, the length of welded seam can increase to 30%-100% with low production speed. Therefore, large diameter welded pipe adopts spiral welding; small diameter welded pipe adopts straight seam welding.

Spiral Welded Steel Pipe


The problems you have to pay more attention during the welding.
In the economic benefit, spiral steel pipe fitting can reduce the costs as much as possible as well as to meet the requirements of engineering design. But it is easy to form selected spiral tube appearing small amount with many varieties so that it hinders construction materials management, regulation and design.

In the concrete construction, spiral welded steel pipe is varied in piping engineering pipe institutional form to meet various engineering conditions especially strict demand for special projects. In engineering design and selection, the strength grade of the steel pipe fitting is much higher, the security is much higher. But the cost of project is relatively larger. This will cause unnecessary wastes.

Therefore, when you select spiral welded steel pipe fittings, you need to consider safety and economy completely and reduce the types of pipe fittings.  In additional, you also need to consider construction conditions, level and purchase cycle of pipe fittings.
