Second, we will show you the process of ERW steel pipes.
Production Process for ERW steel pipe:
First step: 1. Uncoiling — 2. Leveling — 3. End cutting — 4. End shearing welding — 5. Supercoil accumulator — 6. Edge cutting — 7. Ultrasonic detection —
Second step: 8. Forming — 9. Electric induction welding — 10. Ultrasonic detection for weld seam — 11. Medium frequency heat treatment — 12. Air cooling — 13. Water cooling — 14. Sizing — 15. Flying cutting — 16. Flush-out — 17. Cropping — 18. Flattening testing — 19. Straightening — 20. End facing and bevelling — 21. Hydrodynamic testing — 22. Ultrasonic detection for weld seam — 23. Ultrasonic detection for pipe end — 24. Visual and dimensions inspection —
Third step: 25.Weighting and measuring — 26. Marking — 27. Coating — 28. Pipe-end protection — 29. Bending — 30. Shipping
Based on the customers requirements we can manufacture ERW pipes and tubes of different size and shape. At the same time, we have a very large production capacity of ERW pipes and tubes.
As can be seen, the ERW pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc.
Packing of 1 1/2-inch ERW Steel Pipe
Packing Styles:
- Plastic plugs in both ends;
- Hexagonal bundles of max. 2,000kg with several steel strips;
- Two tags on each bundle;
- Wrapped in waterproof paper;

Bundled 1 1/2-inch ERW Steel Pipe
In a word, different sizes of pipes have different pieces in one bundle. So please see the photos of 1 1/2-inch ERW steel pipe in Bundle below.
Usually we make small sizes of pipe in bundle like this. It is convient for loading and shiping.
For example, total 61 Pieces ERW steel pipe in one bundle for 1 1/2inch pipes..
All of our factories have certificates, such ISO 9001, ISO 14001, OHSAS 18001 since 2000. Certificates API 5L PSL 1 & PSL 2, API 5CT, PED, CPR certificates. Also we accept 3-party inspection point by clients, such as SGS, BV and etc.
In short, we are assure all our products in good quality and our best services.
