Metal compensators are also called metal expansion joints.
One. summary of metal compensators
Mainly used for metal compensator is mainly used for power plant flue, used to absorb the thermal displacement and (or) damping, rectangular fillet compensator (UV waveform) nominal I rectangular pipe size specification, the corrugated pipe fillet limit, remove small caliber specifications, single and double wave wave wave, three wave and four wave each wave number corresponding to the 99 Kinds of specifications.
Two. Performance parameters of metal compensator
1. Use of pressure (P): -30~30kPa
2, the use of temperature (T): less than or equal to 400 DEG C
3, bellows material
High weather resistant steel 09CuCrNi-A (GB4171) and austenitic stainless steel 0Cr19Ni9 (G) are commonly used
B3280) and common carbon steel Q235-A (GB700)
High weatherproof steel has good atmospheric corrosion resistance and high performance price ratio, and is recommended for use.
Three. Characteristics of metal compensator:
1, noise reduction and shock absorption: fiber and insulation cotton itself has a sound absorption and shock absorption function, can effectively reduce the noise and vibration of the boiler and the fan.
2, multidirectional compensation: a non-metallic Compensator can provide a larger axial, angular and lateral displacement in a smaller size range.
3, there is no reverse thrust: the main material is glass fiber fabric and its coated products. It is unable to transfer. The use of non-metallic Compensator can simplify the design, avoid the use of large stents, and save a lot of materials and labor.
Four. Use of metal compensator:
1, iron and steel works: blast furnace, converter, exhaust and other dust removal system.
2, smelter: combustion furnace and other exhaust system.
3, cement plant: kiln, dust collection, smoke and dust treatment system.
4, device category: dust collector, absorption tower, air heater, air blower equipment import and export.
5, thermal power plant: boiler, gas turbine exhaust system, dust removal system.
6, petrochemical enterprises: boiler, industrial furnace flue gas desulphurization device, wet, dry ventilation duct.
Four, metal compensator product picture display
Five. Application scope of metal compensator
Is a new type of power plant flue metal flexible pipe based on generic products in the United States, "CE" and the international standard and the development of China's power plants with special circumstances, this product is a power plant, metallurgy, cement, petrochemical equipment system is an important part of the flue gas price Datong off fluid conveying pipeline safe operation area, the deformation caused by the geometric and material nonlinearity the temperature and load in compared with the similar single angle, double angle, low angle, small wave bellows point pen products showed excellent working angle I Mei excellent quality quality, the domestic design institutes, engineering units, project owners choose more and more high recognition rate and has been widely used.
