Two common problems in spiral pipe production

Spiral pipes are also called spiral steel pipes or spiral welded pipes. They are made by rolling low carbon structural steel or low alloy structural steel strips into pipe blanks at a certain spiral angle (called forming angle), and then welding the pipe seams. , which can produce large-diameter steel pipes from narrower strips.

1. The thickness, appearance, and length requirements for spiral steel pipes are not very large, but they cannot be too terrible. There are no requirements for the appearance as long as it does not affect the normal use of the spiral steel pipe, but it cannot be said to be round. Make it square.
2. The surface layer is generally inspected for cracks, cracks and expansion. The surface layer of the spiral steel pipe may have bumps, but there are limited standards for these bumps.

Spiral steel pipes have the following advantages in steel structure workshops. The standards of spiral steel pipes are highly adaptable, which means that spiral steel pipes can be produced according to any standard. The length of spiral steel pipes can also be arbitrary, up to 30 meters long. Spiral steel pipes It can also be made into jointed pillars, which have better performance than channel steel and are cheaper.
