Buried corrugated compensator Model: The company DN32-DN1600, pressure level 0.25Mpa-2.5Mpa Buried corrugated compensator axial compensation: 30mm-500mm a model example: Example: 1.6ZMS200 × 6J, said: Work pressure of 1.6MPa, nominal diameter of 200mm, wave number six waves, take over the connection Buried corrugated compensator. Second, use: Buried corrugated compensator is mainly applied axial compensation, but also has superior resistance to bending, so I do not consider the impact of the pipeline sinking. Achieve free expansion compensation under Buried bellows housing and the guide sleeve to protect other properties with the same ordinary corrugated compensator. Note that when using the internal pressure bellows buried requires between two fixed bearing only install a bellows, his compensation for bearing force calculation and single corrugated compensator for bearing force compute the same, due to internal pressure corrugated compensator Buried compensation and achieve freedom and simple installation, design engineering and installation so popular with users on the pipeline. Second, the 2.1 use: Buried corrugated compensator is mainly applied axial compensation, but also has superior resistance to bending, so I do not consider the impact of the sinking of the pipeline to achieve freedom under Buried bellows covers and guide sleeve protection Telescopic compensation other properties identical with ordinary corrugated compensator. 2.2 thermal deformation: △ L = a · t · L = 0.0133 × 360 × 30 = 143.6mm Note: expansion coefficient of a carbon steel commonly used for temperature t of media channels - Install compensator L at ambient temperature for two length three, installation considerations between fixed bracket: 3.1 In order to play Buried corrugated compensator compensation, compensation must be located at both ends of the bracket fixed to prevent pipeline affected by the internal pressure thrust outward stretch. End 3.2 Buried corrugated compensator (finger-way compensation Buried compensator dead-end) to be close to the end of the mounting bracket, with live head to compensate for pipe compensator. 3.3 Setting the two mounting bracket according to the amount of compensation Buried corrugated compensator distance, the amount of compensation does not exceed the diameter. 3.4 pressure test procedure to Buried corrugated compensator not appear stretch phenomenon.
