| Parameter | Capability |
| Outer Diameter | Φ219 – Φ3620 mm |
Wall Thickness | 6-25.4mm |
Single Length | Up to 30 m (Asia’s longest) |
Competitive positioning: EN 10217-1 products in the market are predominantly longitudinal welded (EW/HFW/SAWL) with practical OD limits around 508 mm. Cangzhou Group’s SAWH capability extends the applicable diameter range to 3620 mm, addressing large-diameter pressure pipeline applications where longitudinal welding is not economically viable.

EN 10217-1 SAWH Pipe – Frequently Asked Questions (FAQ)
1. What is EN 10217-1 SAWH pipe?
EN 10217-1 SAWH pipe refers to spiral welded (SAWH/HSAW) non-alloy steel pipes manufactured according to the EN 10217-1 standard. It is designed for pressure purposes with specified room-temperature properties, available in TR1 and TR2 quality grades.
2. What is the difference between EN 10217-1 TR1 and TR2?
TR1 is a basic quality grade with non-specific inspection. TR2 has stricter requirements, including specified aluminium content, impact properties, and specific inspection options. TR2 is intended to support the EU Pressure Equipment Directive (PED) 2014/68/EU.
3. Can you supply P235TR1 pipe and P235TR2 spiral pipe?
Yes. We manufacture both P235TR1 pipe and P235TR2 spiral pipe, as well as P195TR1/TR2 and P265TR1/TR2 grades. P235TR2 is commonly requested for PED-compliant pressure applications.
4. What is the maximum size of EN 10217-1 SAWH pipe you can produce?
Our spiral welded pipe EN 10217 capabilities cover an outer diameter range of Φ219 mm to Φ3620 mm, with wall thickness from 6 mm to 30 mm. This far exceeds the typical size range of longitudinally welded EN 10217-1 pipes, which are usually limited to around 508 mm OD.
5. What is the single length of your SAWH pipe EN 10217?
We can produce single lengths up to 30 meters, which is among the longest in Asia. Longer single lengths reduce the number of field girth welds, lowering leakage risk and improving construction efficiency.
6. Is your EN 10217-1 welded pipe PED compliant?
Our TR2 grade EN 10217-1 welded pipe is manufactured to support PED 2014/68/EU essential safety requirements. For PED Categories II, III, and IV, we can supply TR2 pipes with specific inspection and EN 10204-3.1 certification.
7. What manufacturing routes do you use for EN 10217-1 SAWH pipe?
We produce EN 10217-1 SAWH pipe under routes 4a, 4b, 5a, 5b, 8a, and 8b. Routes 4b, 5b, and 8b are suitable for TR2 quality with normalized delivery condition.
8. What tests are performed on EN 10217-1 pressure pipe?
Mandatory tests include cast analysis, room-temperature tensile test on base material, weld bend test for SAW tubes, impact test (TR2), leak-tightness test (hydrostatic or electromagnetic), dimensional inspection, visual examination, and NDT of the weld. For SAWH TR2 pipes, NDT of plate/coil end welds is also required.
9. What is the hydrostatic test pressure for EN 10217-1 pipe?
Test pressure is the lower of 70 bar or calculated by the formula P = 20 × S × T / D, where S = 70% of specified minimum yield strength. Hold time is at least 5 seconds for OD ≤ 457 mm and 10 seconds for OD > 457 mm.
10. What are the typical applications of room temperature pressure pipe EN 10217?
Typical applications include HVAC heating pipelines, fire protection sprinkler systems, industrial plant pressure piping, and power station auxiliary piping.
11. Do you offer EN 10217-1 pipe manufacturer China pricing?
Yes. As a direct EN 10217-1 pipe manufacturer in China, we offer competitive P235TR1 pipe supplier pricing and SAWH pipe price quotes. Contact us with your specifications for a free quotation.
12. What coating options are available for EN 10217-1 welded steel pipe?
We provide in-house coating services including FBE, 3PE, 2PE, 2PP, 3PP, epoxy coal tar, and cement mortar lining. Integrated coating ensures better pipe-coating interface quality.
