SS Tubings are finished in accordance with customer needs regarding dimensional and wall thickness specifications as well as heat treatment for more demanding applications. In general a SS seamless Tubing is manufactured in sizes from 1/8” to 24” according to current standards API, ASTM, and ASME. If required for special projects we can also supply seamless Tubings for large diameter sizes.
