AP-Annealing (solid soluble) and Pickling (acid wash), taking two words to start with the letter AP represents two production processes, that is, after the "solid soluble, acid-washed" process of the tube called AP tube. Although the application of BA tube is becoming more and more pipe, the application of AP tube is still the most extensive. Due to the process design and production conditions requirements of the promotion of the pipe cleanliness, tolerance accuracy, inner wall roughness has a certain high requirements, we can meet.
