High Chromium Cast Iron Bimetal Cladding Pipe

High Chromium Cast Iron Bimetal Cladding Pipe, High Chromium Cast Iron pipe, Bimetal Cladding Pipe We are manufacturer of High Chromium Cast Iron Bimetal Cladding Pipe and supply high quality High Chromium Cast Iron Bimetal Cladding Pipe in both large and small quantities worldwide and offer you the best prices in the market. These Steel-high chromium cast iron bimetal cladding pipe is a new type of abrasion proof piping developed by our company. Outer of straight pipe is common steel pepe, cladding realized by forming high chromium lining via centrifugal forming technique. Outer of bend uses hot-bending bend and lining is cast with high-chromium cast iron. Compared with traditional wear-resistant alloy cast iron, wear-resistant alloy cast steel, general cladding steel pipe and cast stone pipe. 1. Good wear-resistance, giving full play to wear-resistance of high chromium cast iron. 2. Withstanding high pressure: It can be used for any pressure rating. Close bonding of outer and lining ...

Laser Welded Finned Tubes process

This line was developed by our engineers combining both our large experience manufacturing extended surface and the most modern laser technology available in the market. The fins (solid or serrated) are helically wound and continuously welded to the tube by a fully automatic laser finning machine. This new laser finning process produces a perfect fin-to-tube bond with lower heat input and improved efficiency in heat flow and resistance to corrosion. Advantages of Finned Tubes Welded by Laser Highest quality product Wider range of products in both geometry and materials Price saving Highest Quality Product The perfect bond between fin and tube improves efficiency in heat transfer and resistance to corrosion resulting in a clean weld fin to tube joint and fully straight fins (no corrugation). Lower energy consumption, reduced cost of consumables and increased efficiency of the process allow us to offer very competitive prices
