Inox Steel India is a leading supplier of Process Piping Materials used in Refinery, Petrochemical, Chemical, Fertilizer, Oil & Gas, Pharmaceutical, Desalination, and Power Plant projects.
Process piping forms the circulatory system of industrial plants, carrying steam, chemicals, hydrocarbons, water, acids, gases, and process fluids under high temperature, pressure, and corrosive conditions.
The most widely used process piping materials worldwide are:
Each serves a specific function in handling different operating pressures, temperatures, and chemical environments.
Together, they create a complete material matrix for safe, reliable, and efficient plant operation.
Process piping refers to piping systems carrying process fluids in critical industries. These lines must withstand:
Different piping materials are selected based on temperature, media, pressure, corrosion level & industry requirements.
| Pipe Standard | Purpose in Plant | Why It’s Used |
|---|---|---|
| ASTM A106 | Carbon Steel Process Lines | For steam, fuel, oil & high-temp lines |
| ASTM A312 | Stainless Steel Lines | For corrosion, acids, water, chemicals |
| ASTM A335 | Alloy Steel High-Temp Lines | For boilers, heaters, reformers, superheaters |
This combination covers 90% of refinery, petrochemical & chemical piping requirements.
(Matching the format used for Duplex, A335, A312, EN 10216-2, etc.)
