1. ALLOY STEEL
T12 SEAMLESS
TUBE
Performance of alloy steel tubes is
greater the other pipes of different
materials. Alloy steel pipes are majorly
used in chemical, petrochemical and
other energy related chemicals.

2. Information
T12 tube materials consist of chemical composition of carbon,
manganese, phosphorus, sulfur, silicon, chromium,
molybdenum. These tubes are produces in various shapes,
sizes, Subject to the chemical ratio and mechanical properties
they have excessively aid in pressure vessels, boiler parts, and
steam boilers.
