- High-frequency Electric Resistance Welding (ERW), Straight Seam Welding, And Spiral WeldingIn the manufacturing process of welded steel pipes, welding process is a crucial link. According to different welding methods, welding technology can be divided into several types. The three most common welding methods are high-frequency resistance welding (ERW), straight seam welding and spiral welProduct knowledge December 10, 2024
- Unveiling 3LPE: How To Protect Your Pipelines From CorrosionImagine you own a pipeline, which is like a hardworking employee that tirelessly transports precious liquids or gases every day. But just like any hardworking employee, pipelines also need protection to prevent them from "rusty" or "sick" in harsh environments. This is where 3LPE coating comes in—itProduct knowledge December 02, 2024
- What is 3 LPE Coating?3 LPE coating refers to the multi-layer coating, it has 3 layers in total. A high performance Fusion Bonded Epoxy (FBE) primer, followed by a copolymer adhesive and an outer layer of polyethylene which provides tough, durable protection. Under the moderately high temperature the 3 LPE coating can offer the protection for the small and large diameters pipelines.Product knowledge October 28, 2022
