In the pipeline project, due to changes in environmental temperature changes, the temperature of medium and pipeline, usually caused by expansion or contraction of the pipeline, especially in the length direction, the deformation of the contraction or expansion of the pipeline will affect the serious function leading to local crack, so you need to set up some position in pipeline compensator the pipeline is used to eliminate shrinkage or swelling deformation of the bad effect, so that the normal work of pipeline. The spherical compensator is to solve the thermal compensation problem of the pipeline by using the random bending of the spherical tube. It is most suitable for the three direction displacement steam and hot water pipeline. The spherical expansion device can be installed in any position, and the working medium can enter or leave at any end. The drawback is the presence of lateral displacement, leakage, maintenance, installation should be blocked at both ends, stored in dry and ventilated room. In the long term, it should be checked regularly to prevent corrosion. The scope of application of spherical compensator:
Spherical compensator is a device to solve the thermal expansion and contraction of pipelines. It can be widely used in metallurgy, petroleum, chemical industry, electric power, light industry, textile, architecture and national defense construction.
1, for heat pipe, thermal expansion compensation, 5-10 times its ability to compensate for the "n" compensator.
2. It is used for the rocket launcher and the aircraft exhaust facilities to compensate for the impact expansion.
3. Used in the vaporized cooling system of metallurgical equipment, such as blast furnace, converter, electric furnace, heating furnace, etc., for universal joints.
4. In all kinds of pipes used in buildings, the damage to the pipes is prevented because of the uneven subsidence of the foundation, or the earthquake.
The scope of application of spherical compensator:
1. The bend of the pipe network.
2. The mountainous or urban network of complex terrain.
3. Pipe network that causes pipeline deformation due to ground subsidence or earthquake.
4. A pipe network with large compensation and limited space position.
5, the pipeline is long, and the pressure loss is small.
6, crossing the road or bridge and other special requirements of the pipe network.
7, the inlet pipe of the sensitive equipment which needs to limit the load of the takeover.
8, in the pipeline need to use the active joint (universal joint) pipe network.
