| Technological process |
Raw material inspection → 2. Tube billet cutting → 3. Forming (hot rolling/cold drawing/coil welding) → 4. Welding (JCOE/ Helical Forming) → 5. Heat treatment (Normalizing/Tempering) → 6 Sizing and straightening → 7. Non-destructive testing (ultrasonic/X-ray) → 8. Surface treatment (sandblasting/galvanizing/spraying) → 9. Water pressure test → 10. Final inspection and warehousing
| Shipping, packaging & transportation |
Q1: What is the minimum order quantity (MOQ) for steel pipes?
A: The regular specification supports a minimum order of 5 tons, while the custom specification MOQ is 10 tons (specific price negotiable).
Q2: How to choose the type of steel pipe (seamless pipe vs. welded pipe)?
A: Seamless pipes are the preferred choice for high-pressure/high-risk scenarios (such as oil and gas, boilers); Structural support/low-pressure fluid priority welded pipe (30-50% lower in cost).
Q3: Can you provide the material certificate?
A: A third-party test report (including chemical composition, mechanical properties, and flaw detection records) will be provided along with each batch of goods.
Q4: How to deal with rust prevention in sea transportation?
A: By default, the outlet pipe fittings are coated with anti-rust oil and stretch film. For special requirements, VCI vapor phase anti-rust packaging can be provided.
Q5: How are non-standard sizes priced?
A: After providing the drawings/parameters, a customized plan and tiered quotations will be issued within 24 hours.
