& does relevant recommendations: 【 pine set limit expansion, reducing rubber joints, rubber shock absorber 】 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.



One-time corrugated compensator is introduced
One-time corrugated compensator in general use in the thermal duct, and the external pressure compensator principle basic same, but it is in the cold after installation, enter the entire network or part of the networks according to the requirements of construction for preheating, when the wall temperature of preheating temperature of the whole network, the compensator coat at the second welding, put it, the compensator is welded into a whole, then the whole piping system are fixed, there will be no compensation.

One-time corrugated compensator basic parameter of the products
Special features: good elasticity
Shape classification: sleeve compensator

One-time installation requirements of corrugated compensator
1, before installation to check the actual length of the corrugated compensator and the maximum length of installation regulations are consistent, if not practical, adjusting with the adjust screw and corrugated compensator on both ends of the parallelism is not greater than 0.003 DN, and no more than 3 mm.
2, disposable corrugated compensator installation shall be equal to the length of the shortest working length and maximum amount of compensation.
3, the maximum number of compensation one-time corrugated compensator should be too in the pipeline after preheating each corrugated compensator in the expansion of the independent section.
4, the user should be according to the pipe diameter, wall thickness, the highest working temperature, the highest working pressure calculation parameters such as pipe suitable preheating temperature.
5, corrugated compensator installation and welding: one-time installation corrugated compensator is a secondary welding.
(1) corrugated compensator according to adjust the installation specified in article 1 of the length and the pipe welding, the welding for the first time.
(2) corrugated compensator in the pipe, and pipe welding, according to the requirements of construction of the entire network or part of the networks for preheating, when the wall temperature of preheating temperature of the whole network, corrugated compensator coat in build it with dense seam sealing, corrugated compensator is welded into a whole, then the whole piping system are fixed, the second welding.
6, installed with corrugated compensator connected to both ends of center with corrugated compensator is heavy, it is forbidden to use force ripple compensator deformation method and pipe ? at both ends
7, corrugated compensator with under the constraints of the internal pressure reasoning components, prevent damage of field pipe network on its, suppression of qualified, should remove the screw.
8, corrugated compensator installed on the pipeline to crackdown after test, test pressure is 1.5 times of design pressure.
9, corrugated compensator should make overall thermal processing, thermal insulation layer thickness should be close to pipe insulation layer thickness has been or.
