Ganpat Metal supplies ASTM A192 tubes for boiler and superheater applications requiring seamless carbon steel tubing for high-pressure service. Specified under ASTM A192 / ASME SA192, these tubes are selected according to the required outside diameter, wall thickness, mechanical properties and boiler design.
For procurement enquiries, specify the required tube dimensions, quantity, length and inspection documentation. These details help match the quotation to your boiler equipment specification and project requirements.
ASTM A192 tubes are seamless carbon steel boiler tubes intended for high-pressure service. The specification permits hot-finished and cold-finished manufacturing routes, subject to the applicable requirements.
Ganpat Metal handles enquiries for ASTM A192 / ASME SA192 tubes based on the grade and dimensional details specified by the buyer. When requesting a quotation, include the outside diameter, wall thickness, tube length and any project-specific inspection requirements.

Mechanical properties are used to assess whether the material meets the specified requirements for boiler-tube service.
| Mechanical Property | Reference Value |
|---|---|
| Tensile Strength | 325 MPa minimum |
| Yield Strength | 180 MPa minimum |
| Elongation | 35% minimum |
Outside diameter and wall thickness determine whether a tube matches the equipment drawing, replacement specification or boiler-tube bundle design. ASTM A192 dimensions should be specified using the required diameter and wall thickness rather than relying on a generic pipe schedule designation.
When requesting ASTM A192 tubes, provide:
ASTM A192 tubes are manufactured using the seamless process. The specified finishing route determines the applicable manufacturing and heat-treatment requirements.
| Aspect | Details |
|---|---|
| Hot-finished tubes | Heat treatment is not required by the specification for hot-finished tubes. |
| Cold-finished tubes | Heat treatment is required after the final cold-finishing operation, at a temperature of 1200°F (650°C) or higher. |
| Dimensional inspection | Outside diameter, wall thickness and length should be checked against the applicable requirements. |
| Purchase specification | The required finishing route and supplementary conditions should be identified in the order. |
