1. What is the weight of your welded pipes per meter?
The weight per meter depends on the diameter and wall thickness. The formula for calculating the weight is: Weight (kg/m) = 0.02466 × (Outer Diameter - Wall Thickness) × Wall Thickness. For example, a 100mm outer diameter, 5mm wall thickness carbon steel pipe weighs about 11.7kg/m.
2. Do you have any certification for your welded pipes?
Yes. We have ISO 9001 quality management system certification, API 5L certification, CE certification, SGS certification, etc. We can provide relevant certification documents according to your needs.
3. Can welded pipes be cut into small sections according to our requirements?
Yes. We can cut the pipes into small sections (such as 1m, 2m) according to your requirements, and process the ends (such as beveling, threading) for free. You only need to specify the length and end treatment requirements when placing the order.
4. What is the service life of your welded pipes?
The service life depends on the material, surface treatment and use environment. Under normal use conditions: 1) Galvanized carbon steel pipes: 15-20 years; 2) Stainless steel pipes: 30-50 years; 3) Anti-corrosion welded pipes (3PE): 40-50 years.
5. Can you provide technical support for the installation of welded pipes?
Yes. We have a professional technical team that can provide installation guidelines, technical parameters and on-site technical support (if needed). We can also provide video tutorials for pipe installation and welding.
