Direct buried corrugated compensator can also be called direct buried corrugated pipe and direct buried two-way expansion device. Direct buried internal pressure corrugated compensator is suitable for pipelines with only axial displacement. This product has the ability to compensate transverse displacement and combined axial and transverse displacement, but because the compensation amount is small, it can be used only as axial compensation. Its characteristics, longer service life, more safe and reliable. The direct buried internal pressure compensator is mainly used for the axial compensation of the directly buried pipeline. It has bending resistance, so the effect of pipeline sinking can not be considered. The product has the characteristics of large compensation and long service life. Free expansion compensation can be realized under the protection of shell and guide sleeve. Other performances are the same as common ripple compensation. Notes for installation of JZM type direct-buried internal pressure axial corrugation compensator: In order to make the buried bellows compensator play a better compensation role, fixed brackets must be installed at both ends of the buried bellows compensator, in order to prevent the pipeline from being affected by the internal pressure thrust and pulling out. 2. The dead end of the one-way compensation direct-buried ripple compensator should be close to the fixed bracket at one end and compensate the pipeline with the movable end of the compensator. 3. Set the distance between the two fixing brackets according to the compensation amount, and the compensation amount is generally less than the diameter of the pipe. The compensator should not be stretched during pressure test. 5. Direct buried internal pressure ripple compensator requires a ripple compensator installed between two fixed supports. The calculation of the force acting on the support by the compensator is the same as that of the single ripple compensator. Advantages: Free compensation, simple installation, large amount of compensation and long service life can be realized, so it is welcomed by engineering design and installation users, and also widely used in the construction of heat network pipelines. Design Temperature: - 20 ~400 Design pressure: 0.25 Mpa~2.5 Mpa Direction of displacement: Axial (a little transverse and angular) Path: DN50~DN1000mm Over the past few years, our Gongyi Hongsheng Pipeline Equipment Co., Ltd. has continuously developed new products, improved product quality, done a lot of research and experiments, put forward a new product structure, greatly improved the performance of the products, and won the praise of the vast number of users. If special specifications of products are needed, they can be designed and manufactured according to user's requirements. And sincerely hope that new and old customers, design units recommend the use of our company's products.
