Non-metallic expansion joints
>Overview
>
Non-metallic expansion joints
are composed of flexible compensation flanges or pipe insulation materials and bolt tie rods, etc., and can be used in relatively Provides large axial, angular and lateral displacements within a small size range. The characteristic is that there is no reverse thrust, the main material is fiberglass fabric and its coated products, and the transmission is weak. The use of non-metallic expansion joints can simplify the design, avoid the use of large brackets, and save a lot of materials and labor. Then it plays the role of sound attenuation and shock absorption (the fiber fabric and insulation cotton itself have the function of sound absorption and shock absorption, which can effectively reduce the noise and vibration of boiler fans and other systems). At the same time, it has excellent high temperature resistance, corrosion resistance and sealing performance. It is coated with polymer materials such as organic silicon and fluorine, and has excellent high temperature resistance, corrosion resistance and sealing performance. Easy to install and maintain.
>Two features
> Non-metallic expansion joints are mainly composed of flexible compensation parts (non-metallic materials) two-end connectors (flanges or end pipes) adjustment parts (threaded tie rods) and thermal insulation materials. It is mainly used for displacement compensation of pipeline systems transporting dust gas, flue gas, coal gas and other gases due to temperature changes, mechanical vibration and foundation sinking.
>Compensation for thermal expansion: Non-metallic compensators (non-metallic expansion joints) can provide large multi-dimensional directional compensation within a small size range.
>Compensation for installation errors: Since system errors are inevitable in pipeline connections, non-metallic expansion joints can better eliminate installation errors.
>Sound-silencing and vibration isolation: The fiber fabric thermal insulation cotton itself has the function of absorbing sound and isolating vibration transmission, which can effectively reduce the noise and vibration of boiler fans and other systems.
>No reverse thrust: Since the main material is fiber fabric, it is weakly transmitted. Design can be simplified by using non-metallic expansion joints.
>Good sealing performance: It has good sealing performance under the action of various media. Easy to install and maintain.
>Three materials

Materials are: silicone rubber laminated glass cloth fluorine rubber coated glass cloth PTFE laminated glass cloth EPDM coating Glass pudding, rubber-coated glass cloth, polytetrafluoroethylene film and other single-layer or multi-layer composite materials, ceramic fiber fireproof cloth, aluminum silicate cotton, stainless steel wire fiber cloth, glass fiber cloth, etc.
>Four application scopes
>Gas turbine exhaust duct
>Desulfurization system
>Various industrial flue duct exhaust systems
>Coal-fired boiler circulating vulcanized bed Flue ducts of boilers and waste heat boilers
>Special reminder:
Huitong Pipeline Equipment Factory is a professional repairer of desulfurization skins (non-metallic expansion joints) and the largest skin maintenance manufacturer in China
> Huitong Pipeline Equipment Factory has pre-maintenance survey technicians and construction teams specialized in replacing non-metallic expansion joints (skin), and has replaced damaged air-leaking (gray) non-metallic expansion joints for many manufacturers (power plants, steel plants, cement plants) Device (skin). In particular, the desulfurization flue ducts of thermal power plants deliver primary air ducts, circulating vulcanized bed boilers, cyclone separator inlets and outlets, absorption towers, slag discharge ports and other important parts that affect the operating efficiency of the equipment. Our company has professional installers who can perform construction in multiple locations at the same time. Our factory has very strict requirements on the skin replacement and installation process. If the skin is damaged and leaked or the overlap is cracked, it will have a huge impact on the supply and suction current of the fans before and after the flue duct, which directly affects the efficiency of the motor. Moreover, if the non-metallic expansion joint of the hot primary air desulfurization flue leaks under high pressure, The overall harm to the non-metallic expansion joint is greater, which will directly shorten the service life of the flue duct or cause damage to the equipment. In addition, for the installation and maintenance of non-metallic expansion joints (skin), we have mature experience, construction procedures and quality assurance from making semi-finished products to assembly to on-site maintenance. Our factory produces desulfurization non-metallic expansion joints and skins for power plants. It is mainly composed of silicone rubber composite cloth, fluorine rubber composite cloth, polytetrafluoroethylene membrane, alkali-free glass fiber cloth, centrifugal glass wool roll blanket and other materials. It has the advantages of high temperature resistance, corrosion resistance and aging resistance. Our factory can customize non-metallic expansion joints of various special specifications on site. Moreover, the sealing belt of the primary blower produced by our factory replaced the original sealing belt of the boiler factory.
> Our factory has entered the industry of power plant desulfurization and metallurgical high-temperature air duct expansion joints since 2006. We specialize in rubber air duct compensator, metal air duct compensator, and fabric air duct compensator, including round, square, round and square. Model, size and diameter, etc., complete specifications, short processing cycle, adopting foreign advanced management system, fast delivery, clamp-type flexible pipe joints (pipe joints) Vickers coupling/pipe coupling Rockwell compensation produced by our factory Device/connector (connector) pipe flexible joint non-metallic (fabric) compensator non-metallic expansion joint
