Jiangsu PVC pipe in the current application of enterprises more and more frequently, is due to compressive strength, stability and fatigue performance and other aspects of relatively good, has been widely used in various enterprises. Such as the most common metal bellows, as a sensitive element, damping components, various automatic control and measurement instrumentation industry production provides a great effect.

Metal bellows is a flexible, thin-walled, horizontal ripple of the shell parts. It has both elastic properties and sealing properties, under the action of external force and torque can produce axial, angular, lateral, and its combination of displacement, sealing performance. The main types of metal bellows metal bellows, corrugated expansion joints and metal corrugated hose three. With the increase in demand, the corresponding also produced a number of methods of manufacturing bellows:

1. Hydroforming, hydroforming can get a better overall performance of the bellows;

2. Rolling forming, roll forming can create large smuggling of the bellows;

3. Welding forming, welding forming can get excellent flexibility of the bellows;

4. Electrodeposition forming, electrodeposition can produce small diameter and high precision of the bellows;

These are the bellows with the popularity of Chengdu, the production of metal bellows production process, can be seen from the metal bellows manufacturing enterprises in addition to the standard production methods for production and processing, but also in the market with the needs of Constantly improve and perfect the mode of production.
