Abstract: The development course of the CPE process is outlined here in the assay.This tube-making process is well capable of producing light-wall steel pipes owing to the large elongation coefficient that ensures D/S of the tube above 40.Based on discussion and analysis of the technology parameters and equipment selection data,it is concluded that the CPE pipe mill suits for manufacturing small/medium sized light-wall seamless steel pipes,being a targeted mill type for upgrading of the small/medium sized seamless steel pipe mill with a moderate production capacity.Moreover,for small-sized pipe production,the CPE process and the MPM process would be complementary to each other.
