DIN 17175 St45.8 seamless pipes are mainly used for heating surface pipes of low and medium pressure boilers. Their working conditions are usually working pressure less than or equal to 5.88Mpa and working temperature less than or equal to 450℃.
The manufacturing process of DIN 17175 St45.8 cold drawn pipes supplied by GNEE usually includes raw material selection, heating treatment, perforation, pickling and cold drawing, heat treatment, testing and surface treatment. Cold drawing is a key step. Through multiple drawing passes, the tube blank is gradually thinned to the required size and shape.
