What Is a Stainless Steel Pipe?
A stainless steel pipe is a hollow, cylindrical steel product made of corrosion-resistant stainless steel alloy.
It can be produced by welding (ERW, TIG) or seamless (hot rolling or cold drawing) methods depending on application requirements.

| Seamless Pipe | Hot or cold drawn | High pressure resistance, smooth surface | Petrochemical, boiler, hydraulic |
| Welded Pipe | ERW / TIG welded | Cost-effective, uniform thickness | Construction, furniture, decoration |
| Square & Rectangular Pipe | Formed and welded | Modern appearance | Architecture, furniture, handrails |
| Polished Decorative Tube | Mirror / HL finish | Aesthetic and rust-free | Interior design, railings, frames |
