product description
Non -Metal Compensator] The basic structure of non -metal expansion joint
It is mainly composed of leather, stainless steel wire mesh, insulation cotton, insulation filler layer, rack, baffle, etc.
1. Skin is the main telescopic body of the non -metal expansion joint. It is composed of multi -layer composite such as silicone rubber or high -silicon polytesilittin tetrafluoroethylene and alkali glass filament.
It is a high -density seal composite material.Its effect is to absorb the amount of expansion and prevent leakage and rainwater leakage.
2. The stainless steel wire mesh is the inner lining of non -metal expansion joints to prevent the miscellaneous objects in the circulating medium from entering the expansion and preventing the insulation materials from the expansion joint.
3. Insulation cotton is a dual effect of insulating and gas tightness that takes into account the non -metal expansion joint. It is a glass fiber cloth,
High silicon oxygen cloth and various types of insulation cotton felt. The length and width of the width are consistent with the skin of the outer layer.
4. The thermal insulation filler layer is the main guarantee of non -metal expansion.
Its thickness can be determined according to heat transfer calculations based on the temperature and thermal conductivity of the circulation medium and the heating coefficient of high temperature resistance.
5. The rack is the contour support of the non -metal expansion joint, which guarantees that there is sufficient strength and stiffness. The material of the rack should be compatible with the medium temperature.
Generally at 400.Use Q235-A? 600 below C.Made of stainless steel or heat -resistant steel above C.The frame generally has a flange that matches the connected smoke wind channel.
6. Brokers are the role of booting and protective thermal protection layer.The material should be consistent with the temperature of the medium.The materials should be anti -corrosion and wear resistance.The baffle should not affect the displacement of the expansion.
Compensator
Angle -oriented compensator should be used in two or three sets of supporting sets to absorb the horizontal displacement of the pipeline. Between the two fixed pipe racks of the Z -shaped and L -shaped pipe segments, only one horizontal compensator or one is allowed to install a horizontal compensator or one one.Corner -type compensator.At this time, the axis of the plane hinge selling must be vertically in the plane formed by the bending pipe section (the universal hinge compensator is not subject to this restriction).Install a set of hinge compensator tube segments, and the gap between the flat guide rackεCan also be calculated by the above formula.However, the length of L should be the distance between the two compensator hinge shafts, and △ X is the thermal expansion volume of the entire vertical pipe section.effect
1. Compensation to absorb the axis, horizontal, and corners of the pipeline.
2. Robe compensator expansion, convenient for installation and disassembly of the valve pipeline.
3. Absorb the vibration of the equipment and reduce the impact of equipment vibration on the pipeline.
4. Absorb the deformation of earthquakes and land to pipelines.
