Mixed acid and hydrofluoric acid can be used for pickling of cold drawn tube blanks. Carbon structural steel pipe billets and alloy structural seamless steel pipe billets are pickled with pickling, high-quality carbon structural steel and high-quality alloy structural steel precision seamless pipe billets, high-alloy seamless steel pipes with high chromium and nickel content are pickled with mixed acid and nitric acid, austenitic Body stainless steel pipes shall be pickled with hydrofluoric acid.
The cold-drawn tube is a precision cold-drawn seamless steel tube with high dimensional accuracy and good surface finish, which is suitable for mechanical structures and hydraulic equipment. Choosing precision seamless pipes to manufacture mechanical structures or hydraulic equipment can greatly save processing time, improve material utilization, and improve product quality.
