The straight pipe pressure balance expansion joint is divided into three forms: bypass type axial pressure balance type, straight through type axial pressure balance type (collectively referred to as straight pipe pressure balance type), and curved pipe pressure balance type (also known as bent pipe pressure balance type).The bypass type and through type pressure balanced expansion joints are mainly used to absorb axial displacement and balance the pressure thrust of corrugated pipes.The curved tube pressure balanced expansion joint is mainly used to absorb axial and lateral combined displacement and balance the pressure thrust of the corrugated pipe....
The key components for thermal compensation in the heat pipe network and equipment, due to the small axial stiffness of the corrugated expansion joint, the axial force generated by the internal pressure of the pipeline often affects the design and use of the pipeline system. The corrugated expansion joint in the pipeline system, in which axial force is transmitted without any constraints, is called a free type (unbalanced type) corrugated expansion joint; The axial force is constrained by certain mechanisms or devices and cannot be transmitted to the corrugated expansion joint, which is called a balanced corrugated expansion joint....
The high-temperature axial corrugated compensator belongs to the metal corrugated pipe, and the materials used are stainless steel and carbon steel, greatly improving the high-temperature and corrosion resistance characteristics of the corrugated pipe....
The small rod type corrugated compensator, also commonly known as the small rod lateral expansion joint or small rod compensator in the industry, is a type of metal corrugated compensator and one of the best-selling products in the application range of expansion joints. It can not only compensate for the angular and lateral displacement of bent pipelines, but also for axial displacement compensation....
The large pull rod ripple compensator, also known as the compound pull rod ripple compensator or the large pull rod compensator, is a flexible component composed of two identical corrugated pipes and end pipes, end plates, and pull rods. It is a relatively new type of ripple compensator, which has the advantages of large compensation, small rigidity, no medium pressure pushing force, safety, no leakage, and low cost. Getting more and more applications....
Caliber: DN100-DN2500Working pressure: 0.25-2.5MPaPerformance characteristics: This type of expansion joint is actually composed of two angular expansion joints combined with a long middle connecting pipe. It can absorb lateral displacement in a single plane direction. Their hinges can withstand the thrust of internal pressure....
A single type (hinge) expansion joint is composed of a connecting pipe, a corrugated pipe, and a pair of hinges connected to the connecting pipe. It has the ability to withstand internal pressure thrust and is used to absorb angular displacement of a single plane....
Unrestricted welded corrugated pipe axial pressure balanced metal expansion joint is a widely used equipment in pipeline systems. It has the functions of compensating for thermal expansion and contraction caused by temperature changes in pipelines, absorbing vibration of pipeline systems, and reducing fluid pressure....
