IV. Product Advantages
One-piece hot pressing forming provides a smooth arc and low fluid resistance. The seamless structure ensures stable pressure-bearing performance, with regular welding bevels suitable for straight seam pipes, spiral pipes, and seamless pipes. The whole fitting can be coated with an anti-corrosion layer for buried soil corrosion resistance, and on-site welding installation is convenient.
