How Many Types Of Seamless Pipe Are There?
1. By Material
| Type | Description | Common Use |
|---|---|---|
| Carbon Steel Seamless Pipe | Made from carbon steel; strong and cost-effective. | Oil & gas, water transport, structural use. |
| Alloy Steel Seamless Pipe | Contains alloying elements (Cr, Mo, Ni, etc.) for high strength and temperature resistance. | Power plants, chemical industries, high-pressure systems. |
| Stainless Steel Seamless Pipe | Corrosion-resistant, smooth inner surface. | Food, pharmaceutical, chemical, and marine industries. |
| Nickel Alloy Seamless Pipe | Excellent corrosion and heat resistance. | Aerospace, petrochemical, and marine environments. |
| Copper / Brass Seamless Pipe | High thermal and electrical conductivity. | HVAC, plumbing, heat exchangers. |
| Titanium Seamless Pipe | Lightweight, strong, and corrosion-resistant. | Aerospace, medical, and seawater applications. |
2. By Manufacturing Process
| Type | Description |
|---|---|
| Hot Rolled Seamless Pipe | Produced through hot piercing and rolling; suitable for high-temperature or high-pressure use. |
| Cold Drawn Seamless Pipe | Further processed from hot rolled pipes; better surface finish, tighter tolerances. |
| Hot Expanded Seamless Pipe | Made by expanding smaller pipes to larger diameters; used for large-size seamless pipes. |
3. By Application / Standard
| Type | Standard Example | Application |
|---|---|---|
| Boiler Tube | ASTM A192, A210 | High-pressure steam boilers. |
| Oil & Gas Line Pipe | API 5L | Transporting oil, gas, and fluids. |
| Mechanical Tube | ASTM A519 | Machinery, automotive parts. |
| Structural Seamless Pipe | EN 10210 | Building structures and frames. |
| Hydraulic & Precision Tube | DIN 2391 | Hydraulic systems, instrumentation. |
