Sleeve Pipe Fittings



As for design of thermal pipelines,designers will change the elevation and trends according to geographical environment and municipal layout,so that the thermal pipelines will be divided into pipe sections with different elevation,trends and straight line distance,relying on existing sleeve,bellow or door type compensation of straight pipes.Accordingly our company,borrowing recommendations of experts,has developed successfully ZXA type rotary compensators,which have been tested on pipelines successfully.



Compared with general sleeve,bellow or door type compensators ,the product has the following characteristics


1. The compensators produces no thrust under internal pressure(or thrust from blind plate),so the rigid bearings on two ends of the compensator can be smaller


2.  In order to prevent sleeve and bellow compensators from being damaged,Strict Calibration is provided in requirements of design and installation.Therefore,an additional guide bracket shall be added before each compensator.The compensator needs no calibration,so it is necessary to install additional guide bracket.


3. The compensator needs no thermal expansion for temperature preservation,so the thermal loss is lower.


4. The compensator adopts sealing materials the most advanced at home as well as logical structure of sealing surface so that the abrasion between sealing materials and sealing surface so that the abrasion between sealing materials and sealing surface is extremely smaller,which guarantees no leakage in a long time.


5. Packing ring and aligning beads for friction reduction are designed inside the rotary sleeve of the operation


6. The compensator has two basic combinations,tens of changes,and the capacity of compensation can reach 1800mm.and one compensator can replace a few sleeves or bellow expansion joints.
