1. Can welded pipes be used for underground pipelines?
Yes. We provide anti-corrosion welded pipes (such as 3PE anti-corrosion layer) which are specially designed for underground use. The anti-corrosion layer can effectively prevent soil corrosion and extend the service life of the pipes (up to 50 years under normal conditions).
2. What is the difference between seamless pipes and welded pipes?
Seamless pipes are made by piercing steel billets, with no welds, high pressure-bearing capacity and suitable for high-pressure, high-temperature and high-precision scenarios, but the production cost is high. Welded pipes are made by welding steel plates, with low cost, simple production process and suitable for general pressure and ordinary scenarios.
3. What is the minimum order quantity (MOQ) for your welded pipes?
The MOQ is 1 ton for standard specifications. For customized products, the MOQ is 5 tons. If you need a small quantity (less than 1 ton), please contact us, and we will try our best to meet your needs.
4. How do you test the corrosion resistance of welded pipes?
We adopt various corrosion resistance tests, including salt spray test (for galvanized and stainless steel pipes), acid-base test, immersion test, etc. The test results meet international standards, ensuring that the pipes can work stably in corrosive environments (such as coastal areas, chemical plants).
5. Can welded pipes be used for oil and gas transportation?
Yes. Our API 5L GR.B, X42, X52 and other grade welded pipes are specially designed for oil and gas transportation. They have high strength, good toughness and corrosion resistance, and comply with API 5L standards, which can meet the requirements of oil and gas pipeline transportation.
