DIN 17175 Pipe Manufacturing Process
The manufacturing process of DIN 17175 seamless pipe includes the following steps:
Raw material preparation: Select steel ingots or billets that meet the standards.
Heating: Heat the billet to a suitable temperature.
Piercing: Use a piercing machine to make the billet into a hollow rough tube.
Hot rolling and cold rolling: Through multiple hot rolling and cold rolling processes, the rough tube is processed to the required size and wall thickness.
Heat treatment: According to different steel grades, corresponding heat treatment (such as annealing, normalizing or tempering) is carried out to improve the structure and properties of the material.
Inspection: Chemical composition analysis, mechanical property testing, dimensional inspection and non-destructive testing are carried out on the pipe to ensure that the product meets the standard requirements.
