Spiral pipe was widely used, and still has its unique advantages. Generally, the bending properties of the helical tube is very good, because in the production process, at least to be bent 180 degrees, and the surface of the spiral tube can not produce cracks.steel tubing clamps

Not only better bending performance the reverse bending performance is also good. Reverse bending test the apex diameter than bending test should be to add a bar diameter. This experiment steps are: first bent 45 degrees forward, after the reverse bend 23 degrees, 23 degrees after reverse bending. After reverse bending experiments, spiral pipe surface is still no cracks.stainless steel tube clamps

Surfaces are generally put into use spiral cracks, scars or signs of folding. Although the surface of the spiral tube to allow a convex blocks, but can not exceed the height of the transverse ribs, and the spiral on the surface of the depth and height of the other defects nor greater than the size of the site where the allowable deviation.

Since the helical coil is used in the transport of gas or oil, so in industrial the above requirements is also relatively high.
