Introduction of several vacuum pipe fittings


Before installing the clamp, you need to align the pipeline, connect the two pipes together, confirm that the inner seal is in place, and then install the clamp. Do not use brute force at this step. If you find that it is not easy to adjust or draw closer, you can adjust the pipeline bracket or loosen the upstream clamp of the pipeline, and avoid brutal construction.

The installation torque of the clamp nut should be strictly in accordance with the standard, and should not be too heavy. Tighten the nut by hand before installing the nut to ensure that its self-locking function is normal.

The circumferential force of the vertical pipe of the main pipe is used to clamp the main pipe or the flexible connection pipe. It is widely used in air conditioning, bleed air, water system hoses and other fields. This type of clamp is generally used in conjunction with the boss on the pipe to fix the hose between the hard pipe boss and the clamp to prevent the hose from loosening.


Corrugated pipes are made of seamless or welded pipes and are usually short in length. A ring-shaped corrugated pipe metal hose assembly is selected in the pipeline or equipment. The ring-shaped metal bellows has good point elasticity and low rigidity. Stainless corrugated pipes are mainly used to pass pipelines, and have good corrosion resistance, high temperature resistance and high pressure resistance.

The bellows compensator is mainly stable and corrosive.

Through reasonable design, the waveform parameters and fatigue life of the bellows, correct installation and perfect stress analysis of the pipe system, the stability of the bellows can be solved.

Reducer size head

The diameter reduction forming process of the size head is to directly put the tube blank with the same diameter as the large end of the reducer into the forming mold. Bundled along the application axis of the tube blank, the metal moves directly along the mold cavity to shorten the shape. According to the reduced diameter of the small and small heads, it can also be directly divided into one-time restraint forming technology and multiple restraint forming processes. The original data of the size head is stainless steel. At the same time, some standard size heads can use steel plates, so stamping and forming technology is used for processing and production. At the same time, the flexibly used stamping die forming process is based on the appearance of the corresponding reference standard and the size of the head. The stamping die can directly press the steel plate for stretch forming after stamping.
