Core Product Standards & Classification
- Our pressure purpose steel pipes are strictly manufactured and tested in accordance with international authoritative pressure pipeline standards, with the most widely adopted EN 10216 (Seamless Pressure Pipe) and EN 10217 (Welded Pressure Pipe) as core production specifications, plus full compliance with ASTM A106, ASTM A53, and other global standards.
Main Differences Between EN 10216 & EN 10217
- EN 10216: Seamless Steel Tubes for Pressure Purposes Hot-pierced seamless structure without any welding seam, featuring uniform metal microstructure. It is the first choice for high-pressure, high-temperature, and fatigue-cycle working conditions, including boiler superheater pipes, petrochemical high-pressure process pipes, and cryogenic pressure pipelines.
- EN 10217: Welded Steel Tubes for Pressure Purposes ERW/SAW longitudinal welded structure with standardized weld seam non-destructive testing. It is specialized for medium and low-pressure fluid transmission, large-diameter pipeline engineering, and industrial circulating pipeline systems, with outstanding cost performance for large-scale projects.
| Comparison Item | EN 10216 (Seamless Pressure Tube) | EN 10217 (Welded Pressure Tube) |
|---|---|---|
| Manufacturing | Pierced seamless, no weld seam | ERW/SAW longitudinal welded |
| Core Strength | Uniform wall, high anti-burst & fatigue resistance | Weld seam weak point, limited cyclic load |
| Working Condition | High pressure, high temp, cryogenic, fatigue cycles | Medium & low pressure, stable continuous flow |
| NDT Rules | Basic NDT optional; no weld radiography | Mandatory UT/RT weld inspection |
| Size Feature | Small/medium OD, thick wall available | Large OD, thin & medium wall mass production |
| Unit Cost | High | Low, cost-efficient for big bore |
| Best Use Case | Power, petrochemical, high-pressure energy systems | Municipal pipeline, general industrial fluid transport |
Dimensional Range & Cost Advantage
EN 10216 Seamless
- Advantage: Small-to-medium OD, extra thick wall, high precision heavy-wall tubes.
- Limitation: Large-diameter seamless tubes have extremely high production cost and long lead time.
- Cost: Higher raw material & processing cost, 25%–50% more expensive than equivalent welded tubes.
EN 10217 Welded
- Advantage: Wide large-diameter size range, stable mass production, short delivery cycle.
- Limitation: Super thick wall specification is hard to manufacture.
- Cost: Low production cost, highly cost-effective for large-diameter, medium-low pressure pipeline projects.
Typical Application Scenarios
EN 10216 Seamless Pressure Tubes
-
High-pressure boilers, superheated steam pipelines, power station heat exchangers
-
Petrochemical high-pressure process piping, natural gas high-pressure transmission
-
Cryogenic equipment, hydraulic high-pressure cylinder barrels
-
Offshore high-pressure fluid pipelines, pressure vessel nozzles
EN 10217 Welded Pressure Tubes
- General industrial medium-pressure water, air, oil delivery pipelines
- Low-temperature municipal heating pipelines, general boiler auxiliary piping
- Large-diameter long-distance fluid transmission, underground utility pipelines
- Low-pressure chemical fluid circulation systems
