Is it better to use spiral steel pipe or straight seam steel pipe for drainage pipe?

Spiral steel pipe is a spiral seam steel pipe welded by automatic double wire and double submerged arc welding process. The spiral steel pipe sends the strip steel into the welding pipe unit. After the rolling of multiple rollers, the strip steel gradually rolls up to form a circular tube billet with an open gap. The reduction amount of the extrusion roller is adjusted to control the weld seam gap at 1~3mm and level the welding mouth at both ends.

Generally speaking, spiral steel pipe is used in drainage pipes, because the strength of spiral welded pipe is generally higher than that of straight seam steel pipe, and the welded pipe with larger diameter can be produced with narrow blank, and the welded pipe with different diameter can also be produced with the same width of blank. However, compared with the same length of straight seam pipe, the weld length and production speed are lower. Therefore, the smaller diameter welded pipe mostly adopts straight seam welding, while the larger diameter welded pipe mostly adopts spiral welding.

Also has generally DN350 above, the tube diameter is big why USES the spiral tube instead of the straight seam tube? Because the weld of spiral steel pipe is spiral, the pressure of liquid will be distributed on all sides of the pipe to enhance the strength of the pipe. If the use of straight seam steel pipe, the general large pipe is rolled up with steel plate for direct welding, the need for large steel plate, greatly increase the production difficulty, so the larger diameter will use spiral pipe. As a professional spiral pipe manufacturer, we have several spiral pipe production lines, which can produce spiral welded pipes with diameter of 219-2820mm and wall thickness of 6-28mm. The price is affordable and the quantity is large.
