Product Introduction

ASME SA249 316L welded tubes are essential components in various industrial applications, known for their excellent corrosion resistance and durability. 316L Stainless Steel Contains 16-18% chromium, 10-14% nickel, and 2-3% molybdenum, with a maximum carbon content of 0.03%. Welded tubes are formed by rolling and welding flat strips or sheets of metal, followed by heat treatment to restore the material's properties. They are cost-effective and can be produced in long lengths without the need for joints, reducing the risk of leaks.

Applications of ASME SA249 316L Welded Tubes:

1. Heat Exchangers
2. Boilers and Superheaters
3. Oil and Gas Industry
