Factors influencing stainless steel pipe prices The brand, material, and manufacturing process are vital, but the steel pipe's surface treatment technique is the most crucial. The internal and external surfaces of the pipe are typically treated in four ways: acid pickling passivation (AP), mechanical polishing (MP), brilliant annealing (BA), and electrolytic polishing (EP) to further enhance the properties of the pipe material. Test results and practical experience have shown that surface treatment reduces the piping material's roughness and weakens surface adsorption. What distinguishes stainless steel pipe of grades AP, MP, BP, and EP?
