Spiral steel pipe manufacturing loss rate refers to the spiral pipe in the manufacturing process, the proportion of raw materials, waste, according to professional and technical personnel for many years statistical analysis spiral tube manufacturing loss rate of between 2% -3%.
During the manufacture of spiral steel pipe, the main components of waste are: the first piece of spiral pipe forming the first piece, the tail to tail, the raw material milling, spiral pipe production process necessary steps, if the production can not be normal spiral pipe milling edge, truncated , To the end, the production of steel pipe pass rate is very low.
When spiral steel pipe manufacturing, there are some losses can be avoided, such as spiral pipe weld quality unqualified, can not be repaired, then the spiral pipe quality unqualified, can not be used, resulting in a waste of material. In the manufacturing process, we must strictly control each process, handle the details, so as to improve the spiral tube yield and pass rate, to avoid unnecessary losses, so that can avoid unnecessary cost.
