双金属复合管
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 HV1100 to1500, as high as that of tungste-cobalt hard alloys, and the abrasion resistance is 20 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 -50 to 800 degrees Celsius.
3.Convenient installation:
It is much lighter than any other types of composite pipes, and can be welded or connected through flanges.
4. Low conveying resistance.
