Product advantages


Special process steel pipe

External steel pipe material can be customized according to customer requirements, 16 manganese, 20# steel and so on.  The outer wall of the steel pipe is marked with different colors according to different needs of customers. The thickness of the outer layer meets the standard.

The inner wall is lined with stainless steel. Ensure that the stainless steel and the inner wall of the outer steel pipe are completely fitted. Stainless steel can not only ensure the anti-corrosion function of the use process, but also reduce the cost compared with the steel pipe of the same thickness of pure stainless steel.
