Constructors, engineers and industrialists have a high demand of tubes. Those hundreds of tubes that can be bought are of various materials like stainless steel, copper, nickel, etc. When you are interested in selecting the one, the best one is Stainless steel 317-317L tube. It is fabricated through a blend of melting, cutting, welding, heat treatment and an array of others that are low in carbon content, with the molybdenum content, which gives the highest erosion protection, 317-317L.
These tubes are protective to welding, sensitization and other thermal processes because of their low carbon. It is also good in erosion which prevents against oxidation. These tubes are also very resistant to corrosion and oxidation. It is rustproof and crackproof and hence can be used in moisture and humid environments. These tubes are loaded at 38degC temperature and can be well guarded against high concentration solutions. Moreover, such tubes are stress bursting and possessing better creep characteristics.
Metinox Overseas is a leading manufacturer and supplier of Stainless Steel 317, 317L Tubes. Our clientele receives an excellent range of quality scope of SS tubes that is manufactured using the high grade stainless steel. The provided range of SS tubes is reputed with power and dimensional accuracy. In addition, due to the national and global character of crude materials, we provide these tubes in variable size and thicknesses following specific orders of our consumers. Such characteristics that are eminent in the SS tubes are high corrosion, abrasion resistance, stress rupture and crevice cracking in heavy loadings at high temperature. The corrosion of the tubes is mostly in the chemical processing. These tubes are, however, used in severe chemical processing plants.
We offer Stainless Steel 317/317L Tubes at an affordable cost, these are also accompanied with varying quality certificates, and you can also demand any specific test according to your requirements.
