Description

Its outer of straight pipe is common steel pipe, 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 , it has many strong points: 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 by adopting special process so that cladding interlayer is molten-joint to ensure reliable operation. 3. Good mechanical impact and thermal impact resistance property 4. Convenient in connection for installation:It can be cut and welded as you like. Scope of application Coal powder conveyer system and dry ash conveyer piping in coal-fired power plant Coal refuse system in coal-fired power plant Other powder and grain pneumatic conveying system Hydraulic conveying system and conveyance of slury with large grain size. Features: 1. High abrasion resistant: Vickers hardness of the corundum lining is HV***0 to***0, as high as that of tungste-cobalt hard alloys, and the abrasion resistance is *0 times as carbon steel pipes. Its rigidity is the highest among all oxides. 2. Corrosion resistant: Corundum is a neutral material, and is acid-proof and fouling-free. Heat resistant: The pipe can work under circumstances of **0 to **0 degrees Celsius. ***** installation: It is much lighter than any other types of composite pipes, and can be welded or connected through flanges. 4. Low conveying resistance.
