| Main Grades | 20, 20-PV, 15GS, 15ChM / 15CrMo, 12Ch1MF / 12Cr1MoV, 15H1M1F |
| Outside Diameter | Cold-formed: 10-76 mm; hot-formed: 57-219 mm |
| Wall Thickness | Cold-formed: 2-12 mm; hot-formed: 3.5-40 mm |
| Length | 1-12 m, customizable; TU 14-3-460-75 commonly lists length up to 9 m by agreement |
| OD Tolerance | Hot-rolled 57-219 mm: ±1%; cold-drawn 10-30 mm: ±0.30 mm; 32-50 mm: ±0.40 mm; 51-76 mm: ±0.8% |
| Wall Thickness Tolerance | Hot-rolled OD ≤108 mm: +15% / -10%; OD >108 mm: +20% / -5%; cold-drawn 2-12 mm: ±10% |
| Straightness | Controlled for boiler installation and tube-bank assembly; tighter straightness available by agreement |
| Surface Condition | Pickled, shot-blasted, polished, oiled, or as-heat-treated |
| Heat Treatment | Normalizing; normalizing + tempering for alloy heat-resistant grades |
| Inspection | 100% non-destructive testing, dimensional inspection, hydrostatic or equivalent testing by order requirement |
| Feature | Technical Value |
|---|---|
| High-pressure boiler service | Designed for steam boilers and pipelines with high and supercritical steam parameters |
| Seamless structure | No weld seam, suitable for pressure-bearing boiler circuits |
| Wide size coverage | Cold-formed 10-76 mm OD; hot-formed 57-219 mm OD |
| Heat-resistant alloy options | 12Ch1MF / 12Cr1MoV contains Cr 0.90-1.20%, Mo 0.25-0.35%, V 0.15-0.30% |
| Strength range | 20 / 20-PV: 412-549 MPa tensile strength; 12Cr1MoV and 15CrMo: 441-637 MPa tensile strength |
| Ductility control | Minimum elongation commonly 21-24% for 20-PV, 15CrMo, and 12Cr1MoV grades |
| NDT requirement | TU 14-3-460-75 product references specify 100% non-destructive testing |
| Buyer Concern | Our Solution |
|---|---|
| Grade selection for temperature and pressure | We help match 20-PV, 15GS, 15CrMo, 12Cr1MoV, or 15H1M1F according to boiler zone, steam temperature, wall thickness, and creep-resistance requirement. |
| Dimensional risk during boiler assembly | We control OD, wall thickness, ovality, straightness, and cut length according to TU 14-3-460 tolerance logic, with additional agreement available for tube-bank fabrication. |
| Material traceability and inspection reliability | Each batch can be supplied with heat number tracking, chemical analysis, mechanical test report, heat-treatment record, NDT record, and EN 10204 3.1-type inspection documentation when required. |
