Premium rectangular compensator with 100% quality

Rectangular corrugated compensators are widely used in the inlets and outlets of central air-conditioning pumps, fire pumps, and daily water supply pumps. They can effectively reduce host vibration, absorb pipeline noise, protect equipment, and extend the service life of equipment. They are durable, resistant to high temperatures, and resistant to high pressure. Anti-corrosion, environmental protection and other advantages. It effectively solves the unsanitary, easy aging, unstable pressure resistance, easy delamination, tearing, explosion and other undesirable factors caused by the old rubber soft joints, and solves the worries of the pump room.
Application scope Various types of pumps, valves, air compressors, various types of fire piping, air distribution piping, steam piping and other general factory piping and mechanical equipment piping in places that require sanitation, need shock absorption and compensation for thermal displacement Places with daily water piping and flexible connections are required.
The rectangular corrugated compensators are placed close to the fixed bracket, and then followed by two guide brackets at separate intervals. The main purpose is to prevent axial instability. The directly buried steam pipeline relies on insulation materials and outer steel pipes. For support or guidance, hot water directly buried pipes are mainly composed of insulation materials and are entirely controlled by soil and sand layers. This installation method has a good starting point, but in practical applications, it is restricted by terrain and there are too many overhead pipe system supports, so the installation is difficult.
There are too many underground obstacles in the directly buried pipe system, and excessive bending may occur. It is required that the rectangular corrugated compensator can only be placed in the straight pipe section. This method of setting up the compensator on the side of the fixed bracket may cause problems due to The displacement of the pipeline causes uneven transmission of the displacement-absorbing capacity of each node of the corrugated compensator, and the performance of the compensation capacity is insufficient. We believe that solving the problem of axial instability of the compensator is not only related to its placement and installation position, but also more importantly depends on the performance and quality of the rectangular corrugated compensator itself. The performance and quality of the rectangular corrugated compensator that is only installed on the fixed bracket side are the same as those of the compensator. The quality requirements should be higher, and the distance between pipeline sections should generally be smaller. When selecting, you must choose a compensator with good self-guidance and strong anti-instability ability. The planning and installation should be based on basic principles, based on the actual situation of the project, and be flexible. For processing, practical conditions have proved that, whether it is overhead or directly buried in the trench, as long as the guide structure is well controlled, the corrugated compensator can be set in either direction of the two fixed brackets.
Rectangular corrugated compensator (type) is also called rectangular compensator, rectangular bellows and rectangular expansion joint. It has axial, transverse and angular compensation functions.
