The rubber joint is a pipe joint installed on the wall. According to its own flexibility, it has the effect of damping and reducing noise on the pipe. Since the role of metal bellows is similar to that of rubber joints, metal bellows are used instead of rubber joints in some areas. But can metal bellows be used as various rubber joints? Let's look at the joints andMetal bellowscommon ground. First of all, the materials are different and do not need to be expressed. The joint is a pipe formed by fusing two carbon steel flanges and a rubber ball, while the metal bellows is a pipe formed by fusing both sides of carbon steel with stainless steel surface and inner layer.
Then there is heat resistance. The key to high temperature resistance of rubber joints lies in the choice of rubber inner layer. So far, fluorine rubber is a very high temperature resistant material for rubber joints, and its high temperature resistance is about 200 ℃, while the high temperature resistance of metal bellows is part of the inner layer of stainless steel bellows, which has good heat resistance and can even exceed rubber joints several times. And their ability to resist pressure. The joint on the pressure layer has a high pressure-resistant joint, but the expected effect is not good. Ordinary corrugated pipe is about 4.0Mpa, while metal corrugated pipe has many pressure resistance, no matter where it is installed, it has good applicability.
The main uses are also different. The rubber joint can only be installed in the pipeline as a simple joint, and the metal bellows can be installed in different parts of the pipeline in addition to being installed in the pipeline as a joint. According to the characteristics of its free rotation, it can transport various materials. However, at the shock absorption level, the rubber joint is made very well. According to the fully utilized materials and their special structure, it has a great effect on the vibration and noise reduction of the pipeline, while the metal bellows can only normally transport cross materials. Their functions are very similar, but the vibration and noise reduction effect of the joint is not achieved by all other pipes.
UseMetal bellowsNote:
1. Due to the long length and large volume of rolled metal corrugated pipes, engineering units usually provide specifications and quantities to manufacturers, and manufacturers will bring equipment and materials to the construction site for processing. This can not only greatly reduce the loss of bellows (short head, bruise, rust, etc.), but also meet the requirements of the demand side and save money.
2. After the metal corrugated pipe is rolled on site, it should be stored in a dry place with a span of 1. The 6-meter thick board is divided into multiple layers of overhead, covered with rainproof tarpaulin and other coverings, and the stacking height should not exceed 7 meters.
3, the handling process should be handled with care, not mixed with other materials and equipment. When the amount of a construction is large, it can be transported by wooden frame, and it is not allowed to be directly tied and hoisted by wire rope.
4. After the metal corrugated pipe is installed, other materials and sundries shall not be piled up on the pipeline to prevent the pipeline from being impacted and deformed.
5. After the pipeline is in place, it should be clearly marked on the specified joint length at both ends of the pipeline to facilitate the connection of the pipeline.
