Stainless steel corrugated compensator is a flexible structure installed on the vessel shell or pipeline to compensate for the additional stress caused by temperature difference and mechanical vibration.
Scope of application
◆ Copper valve series
Gate valve, ball valve, globe valve, check valve, float valve, filter and other products
◆ Universal valve series
Gate valve, ball valve, butterfly valve, stop valve, check valve, safety valve, exhaust valve, pool bottom valve, pressure reducing valve, hydraulic control valve, electric valve, pneumatic valve and other products
◆ Shock absorber series
ZD and DFG damping spring composite shock absorbers, ZTA and ZDG damping spring shock absorbers, YZD, DZD and DZTA heavy load damping spring vibration isolators, stainless steel bellows are divided into several types: bellows compensator, sleeve compensator, rotary compensator, square natural compensator, etc., of which the bellows compensator is more commonly used, mainly to ensure the safe operation of the pipeline, with the following functions:
1. Compensate the axial, transverse and angular thermal deformation of the absorption pipe.
2. The expansion capacity of the corrugated compensator is convenient for the installation and disassembly of the valve pipe.
3. Absorb equipment vibration and reduce the impact of equipment vibration on the pipeline.
4. Absorb the deformation of pipeline caused by earthquake and ground subsidence.
Advantages and Characteristics
1. Reduce project cost
According to the estimation of relevant departments, polyurethane insulated steel pipes can generally reduce the project cost by about 25% (using fiberglass as the protective layer) and 10% (using high-density polyethylene as the protective layer).
2. Low heat loss and energy saving
The thermal conductivity of polyurethane is: λ= 0.013-0.03kcal/m · h · oC, which is much lower than other commonly used pipeline insulation materials in the past, and the insulation effect is improved by 4~9 times.
3. Anticorrosion, good insulation and long service life
As the polyurethane rigid foam insulation layer is closely bonded to the outer skin of the steel pipe, it can isolate the infiltration of air and water and play a good anti-corrosion role. At the same time, its foam holes are closed, and its water absorption is very small.
