Need to pay attention to the use of internal pressure is directly buried bellows compensator requires only a ripple compensator is arranged between the two fixed bearing, calculation and single corrugated compensator of the compensator on bearing force calculation of bearing force is the same as that of the internal pressure due to the buried corrugated compensator in the pipeline to achieve free compensation and simple installation, and thus by the engineering design and the installation of users welcome. Thai Billiton is the company's most professional corrugated compensator manufacturers, has achieved a number of well-known brands of OEM purchasing qualifications. Always pay attention to the R & D Chaochuang pipeline always adhere to scientific and technological innovation, to meet the diversified needs of users, perennial with a variety of conventional products, and provide customized solutions for the user terminal customer orientation, sincerely hope to have the strength to our company to negotiate cooperation and also welcome to purchase our products.

Standard number of standard ripple compensator

Standard Name: metal corrugated compensator bellows general technical conditions, the promulgation and implementation of department: People's Republic of China State Administration of Quality Supervision Inspection and quarantine, China national standardization management committee standard metal corrugated compensator pattern definition, requirements, test method, inspection rules, signs and packaging, transportation and storage. This standard is applicable to the flexible parts installed in the pipeline for the overall shape without strengthening U shape, U shape and strengthen the inverted U-shaped bellows circular corrugated pipe compensator design, manufacturing and inspection. The design, fabrication and inspection of expansion joints for pressure vessels may also be used in reference.

Testing

Because of the different compensation forms of different types of ripple compensators, there are mainly axial, transverse, angular and combined compensation methods. For a kind of wave compensator with various displacements at the same time, the total equivalent axial displacement is obtained by synthesizing its various displacements, and the detection is equivalent to the total equivalent axial displacement. That is to say, the detection of nominal displacement of the ripple compensator is to detect the total equivalent axial displacement. The nominal displacement of a general type bellows is in fact the capacity of the nominal displacement deformation given by the bellows. The tube made of corrugated expansion joint (compensator), compensator, commonly referred to as the amount of compensation, reflects the ability to absorb displacement of the corrugated pipe system, that under certain conditions, the product has the ability of compensation. When the bellows work normally, the displacement of the system must be absorbed to produce displacement and deformation. At the same time, a certain number of times of normal safety work and displacement cycles must be guaranteed. The corrugated pipe in the design, according to the displacement of each wave can withstand, there is a certain number of corrugated design, as each wave are uniformly under displacement load, no local overload, the bellows can work normally. When the design is reasonable, the design cycle displacement times can be guaranteed. In the JB/T 6169-92 metal bellows standard, the test of this performance is specified

With the end of the transition period of China's accession to the WTO, the design of the long distance pipeline design market will be further opened and the international competition will be more intense. Therefore, a pipeline management quality is designed, buried corrugated compensator factory design enterprises how to guarantee and improve the quality of design, pipeline construction and enhance the strength and adapt to the market's needs, have become very concerned about the engineering design consulting industry and government departments of the problem.

Bellows compensators are mainly used for connections, largely to compensate for them. Although there is also the role of noise reduction, but the most widely used is the compensation. It requires either anti stress or strength requirements, if the Jia, when the choice of bellows should carefully check the specifications and pipeline configuration, the most important thing is to meet the design requirements. Only in this way can there be no accidents.

Directly buried corrugated compensator industry plays a very important role in the development of national economy as an important part of preparing the manufacturing industry. Because the domestic buried corrugated compensator of China's manufacturing industry level compared with the international advanced level there is still a certain gap, a lot of key buried corrugated compensator with high parameter, high temperature and high pressure, high class original has been dependent on imports, in order to promote the localization of buried corrugated compensator of the "on accelerating the development of the equipment manufacturing industry a number of opinions" after, the relevant departments of the state according to the localization of major equipment made by the country's request, has made a series of major deployment, and led by the national development and Reform Commission, Chinese Machinery Industry Federation and China General Machinery Industry Association, made the deployment of buried corrugated compensator localization scheme for major equipment and related fields, and many coordination the relevant departments, the localization of buried corrugated compensator has formed a consensus in the domestic industry is now buried corrugated compensator.

Universal bellows compensator: the compensator with the inner sleeve shall be noted that the direction of the inner sleeve is consistent with the direction of the medium flow, and the hinge rotation plane of the hinge type compensator shall be in accordance with the displacement rotation plane.

It is strictly prohibited to adjust the installation tolerance of the pipe with the method of distortion of the corrugated compensator so as not to affect the normal function of the compensator, reduce the service life and increase the load of the piping, equipment and supporting components.

Piping installation is completed, should be removed as soon as bellows used as transportation and installation of yellow auxiliary positioning components and fasteners, and according to the design requirements will be transferred to the specified position limiting device, the pipe system has the ability to compensate fully in the environmental conditions.

In hydraulic test, the secondary fixing pipe support with the end of compensator pipe shall be strengthened so that the pipe will not move or rotate. Yes, for gas
