TP304 304L 316 Stainless Seamless Steel pipe

Short Description:

Stainless steel seamless steel pipes are made from steel ingots or solid tube billets through perforation and then made by hot rolling, cold rolling or cold drawing. Stainless steel seamless steel pipes are mostly used as pipelines for transporting fluids, and are widely used to make structural and mechanical parts, such as oil drill pipes, car drive shafts, bicycle frames, and steel scaffolding for construction roofs, etc.

Stainless steel seamless pipes are steel pipes that are resistant to weak corrosive media such as air, steam, and water, and chemically corrosive media such as acids, alkalis, and salts, also known as stainless acid-resistant steel pipes.

The corrosion resistance of stainless steel seamless pipes depends on the alloying elements contained in the steel. Chromium is the basic element for the corrosion resistance of stainless steel. When the chromium content in the steel reaches about 12%, the chromium interacts with the oxygen in the corrosive medium to form a very thin oxide film (self-passivation film) on the surface of the steel. , Can prevent further corrosion of the steel matrix.

Stainless steel seamless pipe production steps: 1. Round steel preparation; 2. Heating; 3. Hot rolled piercing; 4. Cut the head; 5. Pickling; 6. Grinding; 7. Lubrication; 8. Cold rolling processing; 9. Degreasing; 10. Solution heat treatment; 11. Straightening; 12. Cut the tube; 13. Pickling; 14. Product testing.

The main stainless steel materials are: 201, 202, 209, 301, 304, 304L, 310, 321, 316 316L, 309S, 310S, 904L, 1Cr17, 1Cr13, 2Cr13, 3Cr13.
