Spiral pipe production of two common problems

Spiral pipe, also known as spiral steel pipe or spiral welded pipe, is a low carbon structural steel or low alloy structural steel steel strip according to a certain helix angle (called forming angle) rolled into a billet, and then welded up the pipe seam made, it can be used to produce a narrower strip with a large diameter of steel pipe.

1, on the spiral steel pipe thickness and design, the length of the upper side of the provisions is not quite large, but can not be too bad too scary, for the appearance of the design is not to jeopardize the normal application of all the basis of the provisions, but can not be said to be round you get into a square.

2, the surface layer of the general inspection of the gap bump and expansion, spiral steel pipe surface layer is able to have a bump, but for this bump is a limited specification.

Spiral steel pipe in the steel structure workshop has the following advantages, spiral steel pipe standard customary strong, that is to say, any standard, spiral steel pipe can be produced, spiral steel pipe length can be arbitrary, the longest can be 30 meters, spiral steel pipe can also be made into a joint pillar, the role of the channel steel than the better, the price is cheaper.
