& does relevant recommendations: 【 duct compensator, metal compensator, in a flexible rubber joint 】 is gongyi city full state pipeline equipment co., LTD. The main business of our company has been made as a special equipment manufacturing license and ISO quality management system certification of qualified companies, the company management concept: the factory in order to "customer needs is our goal" principle, wholeheartedly for the customers with excellent products, reasonable prices, fast delivery cycle, professional technical support and perfect after-sales service. In the future, full state is full of confidence and hope, was determined in a more high quality brand and good service, sincere cooperation with customers at home and abroad, to do the northern area of the thermal compensation smoke duct equipment industry's first brand.



Circular non-metallic compensator is introduced
Circular non-metallic compensator can be classified according to different working temperature and the amount of compensation, it is mainly used for power plant smoke duct, used to absorb the thermal displacement and (or) shock absorption.
Non-metallic compensator is mainly composed of nonmetal ring round, insulation material and steel structures, including non-metallic ring by fiber fabric, silicone rubber, fluorine adhesive performance of non-metallic materials such as optimization combination and become, its product strength, offsets, sealing, corrosion resistance and performance indexes such as service life can be comparable with similar foreign products.

The material of circular non-metallic compensator
A, metal structure material usually recommend t 400 ℃ or less, use Q235; 400 ℃ (t 450 ℃ or less, selects the material Q235), using other material should be as a special design;
B, non-metallic ring and insulating materials, according to the different work temperature, glass fiber cloth, teflon film, composite rubber fiberglass cloth, aluminum silicate fiber cotton and other materials.

Circular non-metallic compensator installation considerations
1) with a flow to the requirements of the compensator should be installed according to the requirements of the medium flow arrow.
2) install compensator, non-metallic expansion joint, expansion joints of pipeline must be properly oriented and fixed compensator can play a role, thus guide and fixed bracket set must be strictly according to the relevant technical data of the design department. For guidance, the principle of fixed bracket setting, please see detailed "corrugated compensator installation".
3) before installation should remove foreign bodies in corrugated pipe and pipe, ensure the normal movement of bellows.
4) compensator, non-metallic expansion joint, expansion of frugality, corrugated pipe is made of thin stainless steel plate forming, so the transportation and hoisting and be careful not to knock ? during welding
5) compensator, non-metallic expansion joint, the installation of expansion joints shall be in accordance with the requirements for piping construction drawing and compensator installation instructions.
6) in order to make the bellows are in good working condition, cannot be used when installing compensator deformation, including axial, lateral and torsional to reset piping installation error.

Must provide the parameters of the circular non-metallic compensator orders
1, circular pipe diameter (DN);
2, use pressure and length;
3, using occasions and medium temperature;
4, connection mode.
