Product Description
EN 10216-1 P235TR1 Pressure Alloy Steel Seamless Tubes
EN 10216-1 P235TR1 Seamless Steel Tubes for Room-Temperature Pressure Service
EN 10216-1 P235TR1 seamless steel tubes are non-alloy pressure tubes designed for room-temperature pressure service, not elevated-temperature boiler service. P235TR1 / 1.0254 is specified under EN 10216-1 for seamless circular tubes with room-temperature mechanical properties; "P" indicates pressure service, "235" refers to minimum yield strength of 235 MPa for wall thickness up to 16 mm, and "TR1" indicates the basic quality level without mandatory impact testing.
Specifications
| Item | Description |
|---|---|
| Material | Non-alloy quality steel |
| Standard | EN 10216-1 |

| Maximum Manganese | 1.20% |
| Maximum Sulfur | 0.020% |
| Maximum Phosphorus | 0.025% |
| Leak Tightness | Hydrostatic test up to 70 bar / 7 MPa or calculated pressure, whichever is lower |
| Straightness Control | ≤0.15% of total tube length and ≤3 mm per meter |
Our Advantages
| Buyer Concern | Practical Solution |
|---|---|
| "Is P235TR1 suitable for pressure equipment?" | We position P235TR1 correctly as a room-temperature pressure tube. For pressure vessels or pipelines requiring mandatory impact testing, we recommend TR2 grades instead of overselling TR1. |
| "Can the tube pass leak-tightness requirements?" | Each tube can be supplied with hydrostatic or electromagnetic leak-tightness testing according to EN 10216-1 requirements. |
| "How do I avoid dimensional mismatch during installation?" | We confirm OD, wall thickness, exact length tolerance, straightness, bevel end, coating, and certificate type before production, reducing cutting loss and site-fit problems. |
Execution Standards
| Standard System | Reference |
|---|---|
| EN | EN 10216-1, seamless non-alloy steel tubes for pressure purposes at room temperature |
| ASTM | ASTM A53 / ASTM A106 can be discussed as project alternatives, not direct one-to-one replacements |
| JIS | JIS G3454 is commonly used for carbon steel pressure piping applications |
| GB | GB/T 8163 is commonly used for seamless steel tubes for fluid service |
| GOST | GOST 8732 / GOST 8734 may be considered for seamless hot-rolled or cold-drawn tube dimensions |
Application Field
Specific application: compressed-air receiver inlet and outlet piping for industrial air compressor systems.
