A stainless steel seamless pipe is made by piercing a solid round billet and then hot-finishing or cold-drawing it to the final size, so there is no weld seam along its length. Because the wall is uniform all the way round, an SS seamless pipe handles higher pressure, cyclic loads and corrosive media more reliably than a welded pipe of the same size.
Innovative Corporation is a leading stainless steel seamless pipe supplier and dealer in Ahmedabad. We stock SS 304 seamless pipe, SS 316 seamless pipe and SS 316L seamless pipe from ½" to 12" NB, with larger sizes and special grades on order.
| Feature | Seamless Pipe | Welded / ERW Pipe |

Seamless SS pipe is better for high pressure, high temperature and critical applications. Welded pipe is more economical and perfectly suitable for low to medium pressure, water, food and structural use.
SS 304 seamless pipe typically costs 20–40% more than welded pipe of the same size. Visit our SS pipe price list or call for current rates.
