welcome everybody to discuss about the steel pipe knowledge

Textured was caused by worn groove with irregular spiral welded pipe surface uneven defects. The diameter is volatile. In general the whole amount to match the effect will be better, mainly considering the cumulative error and probability theory to this problem. Prone to fold. Easy to crack.Spiral welded steel pipe used in production and will often appear quality problem, affect the normal use, in some aspects need to be in the identification of the spiral welded pipe quality, according to certain way and the performance test, can have important role in practical use, so how to identify counterfeit method of the spiral welded pipe: appearance often have pitted surface phenomenon. Above points if there are any deficiencies, please supplement, welcome everybody to discuss about the steel pipe knowledge, progress in the continuous communication.


Causes of stainless steel shower handrial fold is due to the pursuit of the false and inferior, high efficiency, large reduction, handle, when the next rolling produce folding, folding products will be cracking after bending, thick wall spiral welded pipe strength decreased. Often appeared phenomenon of discontent, because manufacturers to achieve big minus tolerance, finished product quantity of the previous way slants big, small iron type, groove filling. Surface are prone to scarring. Cold shearing machine high tonnage, cutting head end face smooth and neat, and shoddy material because the material is poor, cutting head end face often have meat, or uneven, and no metallic luster.


High quality components uniform spiral welded pipe. Fold is formed on the surface of the spiral welded pipe line, this kind of defect often throughout the entire product longitudinal. Transverse reinforcement and low. And due to low and inferior material manufacturers cut head, end there will be a big handle. Deep scratches to reduce the strength of the seamless steel tube.


Reason is false and inferior material factory equipment simple, easy to produce burr, scratch surface of spiral welded pipe. Because want to pursuit of profit, and inferior spiral HanGuanChang home often appear groove rolling the overweight. Easy to scrape. Because its billet is adobe, adobe air, adobe in the process of cooling due to the effect of thermal stress, cracks, after rolling there is crack.
