1. General non-alloy steel welded pipes
Core American standard: ASTM A53 (seamless and welded steel pipes)
Material benchmark:
| EN10217-1 Material | ASTM A53 Material |
|---|---|
| P235TR1/TR2 | Gr.B3 |
| P265TR1/TR2 | Gr.B |
Application scenarios: building structure support, low-pressure fluid transportation (water/gas)
Process requirements: Both must meet the water pressure test and non-destructive testing standards
2. Dedicated for low-pressure fluid transportation
American standard option: ASTM A135 (resistance welded steel pipe)
Matches water pipes and HVAC pipes in EN10217-1 (such as P235TR2 grade)
Wall thickness range: compatible with European standard S275 grade welded pipe
️
3. Special restrictions
Pressure level difference:
EN10217-1 is applicable to design pressure ≤16bar, while ASTM A53/A135 covers Class A/B (corresponding pressure ≤20bar)
Sectional form:
EN10217-1 is mainly round tubes, and American standard ASTM A53 supports both round tubes and square tubes
High temperature applicability:
Both are not applicable to working conditions of>350℃ (ASTM A106 or EN10217-4)
Selection recommendation: ASTM A53 Gr.B (strength matches P265TR1) is preferred for building structures; ASTM A1355, which is more cost-effective, can be selected for pure fluid transportation scenarios. When it comes to corrosive environments, anti-corrosion coating treatment is required. GNEE Group provides anti-corrosion coating processing services.
