The internal weld seam leveling machine is an online processing machine for stainless steel welded pipe welds, which synchronously repeatedly rolls the internal and external welds of the welded pipe to ensure a smooth transition between the weld seam and the wood, highlighting the advantages of seamless welded pipe. The equipment adopts PLC and proportional hydraulic automatic control, with stable performance, high yield, convenient installation, error output setting, and linkage with startup input and pipe production line. It is a necessary production equipment for advanced industrial welded pipes.

Stainless steel welded pipes are superior to stainless steel seamless pipes in terms of material and mechanical properties, but the removal of internal and external weld reinforcement, especially the internal weld reinforcement, has always troubled stainless steel welded pipe production enterprises. Although there are solutions such as built-in scrapers or internal grinding devices, the results are not ideal. This seriously hinders the further expansion of the application field of stainless steel welded pipes. At present, stainless steel seamless pipes are mainly used in industries such as petroleum, chemical, nuclear power, boilers, food, and medicine.
