What is the surface finish of sanitary seamless pipes?
The surface finish of sanitary seamless pipes refers to the microscopic smoothness of the pipe inner surface, typically expressed as surface roughness Ra (μm). In modern engineering standards, “surface finish” is formally replaced by surface roughness, which is a measurable parameter used to evaluate hygiene-grade piping quality.

What are specifications of mechanical tube?
Mechanical tubing refers to steel tubing used primarily for mechanical structures, load-bearing systems, power transmission components, and precision engineering applications. Unlike standard pressure piping, mechanical tubes focus more on dimensional accuracy, surface finish, machinability, and mechanical performance rather than internal pressure resistance alone. This guide explains mechanical tube standards, dimensions, manufacturing methods, tolerances, materials, and real-world industrial applications.

Why is 316L stainless steel pipe resistant to chloride ion corrosion?
316L Stainless Steel Pipe resists chloride ion corrosion mainly because it contains molybdenum (Mo) and low carbon content, which improve the stability of the passive oxide film on the steel surface. This protective film helps reduce oxidation, pitting corrosion, and stress corrosion cracking in many industrial environments.

What to do if 316L thick-walled stainless steel pipes corrode?
Although 316L thick-walled stainless steel pipes are known for their excellent corrosion resistance, high-temperature stability, and impact strength, corrosion can still occur under certain service conditions. These pipes are widely used in pharmaceuticals, food processing, chemical plants, industrial piping systems, exhaust systems, and mechanical manufacturing. However, long-term exposure to chlorides, moisture, acidic media, or electrochemical reactions may gradually damage the protective passive layer on the pipe surface. Once corrosion appears, timely anti-corrosion measures are essential to prevent pipeline failure and extend service life.
