The introduction of non-metallic expansion joint
Non-metallic expansion joint compensator, non-metallic compensator, also known as the fabric is one of the expansion joint. Can compensate the vibration of the fan, air duct operation and pipeline deformation. Simple structure, light weight, easy maintenance.
Expansion has taken to utilize the bellows compensator of the elastic element of effective telescopic deformation to absorb piping, conduit or vessel from such sources of heat bilges cold shrink the size change of a kind of compensation device, belonging to a compensation element. For axial, lateral and Angle to the displacement of the absorption compensation, used in pipeline, equipment and system of heating displacement, mechanical displacement to absorb vibration and reduce noise, etc.

Non-metallic expansion joint of special materials
1, special super austenitic stainless steel: 254 smo, 904 l, AL6XN
2, duplex stainless steel: 2205 dual phase steel (S31803)
3, nickel-based alloy steel: INCOLOY800 / ht 800 h / 800/840/825, INCONEL600/601/690/625 / hartz alloy C - 276 - X - 750 / C - 22 / X, MONEL400 / K500
4, pure nickel: N4 interchange, N6 (Ni200, Ni201)
5, stamping with titanium plate: GR1, GR2, TA1, TA2
6, austenitic stainless steel SUS304, SUS304L, SUS316, SUS316L and SUS310S, SUS321, SUS316Ti
The expansion joint on the container, there are a variety of forms, as for the corrugated shape, with u-shaped expansion joint used most widely, followed by Ω shape, C shape, etc. And used in the line of the expansion joint in terms of compensation structure, and can be divided into axial, angular, horizontal type, pressure balance type, hinge and buried type, etc. In terms of material, can be divided into the metal expansion joint and expansion joint non-metallic expansion joint.
1) metal expansion joint to compensate for the additional stress caused by temperature difference and mechanical vibration, and set up on the vessel or pipe of a flexible structure. As it as a freely adjustable elastic compensation components, reliable operation, good performance, and the advantages of compact structure, has ?
Rubber expansion joint (1) air duct is divided into FDZ, FVB, FUB, XB, four kinds of models, from rubber and rubber fabric composite material, steel flange, socket, thermal insulation materials, mainly used for a variety of flexible connection between fan, air duct, its function is to shock absorption, noise reduction, displacement and sealing, medium resistance, easy installation, is a kind of very ideal environmental protection field shock absorption, noise reduction, the best accessories and smoke prevention and dust control.
(2) the fabric material for the expansion joint is mainly for the fabric, high temperature resistant materials. Fabrics expansion joints can compensate the axial, lateral and angular product, with no thrust bearing design, simplify sound vibration, corrosion resistance, high temperature resistant, etc., especially suitable for power plant hot blast pipe and soot pipe.

The structure characteristics of non-metallic expansion joint
Thermal expansion: 1, compensation can compensate the direction, much better than that of unitary compensation only metal compensator.
2, compensation installation error, because in the process of the pipe connection, system error is inevitable, fiber better eliminate installation error compensator.
3, sound isolation: fabrics, heat preservation cotton itself has the function of sound absorption, vibration insulation transmission can effectively reduce boiler, fan noise and vibration of the system.
4, no reverse thrust: as the main materials for fabrics, unable to pass. With fibre compensator can simplify the design, avoid using large bearings, save a lot of materials and Labour.
5, good high temperature resistance, corrosion resistance; Selection of fluorine plastics, organic silicon material has good resistance to high temperature and ?
6, light weight, simple structure, easy installation and maintenance.
7, sealed performance is good: there is a perfect system of production, assembly, fiber compensator can ensure no leakage.
8, the price is lower than metal compensator, the quality is not lower than the imported products.
Non-metallic expansion joint connection mode: 1, 2, to take over the connection flange connection
Non-metallic expansion joint type: 1, straight type 2, type Angle to the compound 3, 4, square (BHJFD type)
