Corrugated compensator using a molding technology, hydraulic accurate size, surface clean and free of injury, the material of austenitic stainless steel. Products, long service life, compact structure, safe and reliable, good interchangeability, no leakage, corrosion resistance, convenient installation and other advantages in one, according to the usual practice, axial bellows are arranged in close proximity to the fixed bracket, and then followed by two guide bracket, distance were 4Dg, 14Dg. 
The main purpose to prevent axial instability, directly buried steam pipeline by thermal insulation material and outer steel pipe support or guidance, hot water pipe depends mainly on the formation and thermal insulation material, the overall control by the soil, sand. Its main function is used as a temperature compensator, in the engineering construction always cannot do without its shadow. In order to technology on the product to be improved, the industry launched a positive work, through the improvement of material and improving the quality of products, so that it can adapt to the working environment with a greater expansion. 
To solve the problem of compensator axial instability in addition to its layout, location on the outside, more important is the performance and quality depends on the compensator itself, should be more layout compensator performance and quality in the fixed bracket side only, pipeline segment distance should be smaller. Selection must be selected from the group consisting of a good guide, anti loss compensator steady ability strong, layout design in accordance with the basic principles, according to the actual situation of engineering, flexible treatment, practice proves, either overhead or buried trench, as long as the good guide structure control, corrugated compensator can be set to any position in the two fixed bracket. Corrugated compensator has been widely used in various types of pipes and equipment, aerospace, power, petrochemical, iron and steel, cement, construction and other industries.
