metal bellows is a pipe with a regular wave-like appearance. Commonly used metal bellows are carbon steel, stainless steel, steel lined with plastic, aluminum, and so on. It is mainly used for non-concentric axial transmission with a small bending radius, or irregular turning, expansion, or absorption of thermal deformation of the pipeline, or where it is not convenient to use a fixed elbow to connect the pipeline to the pipeline, or to connect the pipeline to the pipeline. Connected use of equipment. The service life of metal bellows is very long, about 5-7 years, but many people will ask, is there any way to increase the service life of metal bellows and make it last longer? This is of course, as long as you pay attention to use and maintain it carefully, you can extend your life by at least one or two years. Let's take a look at the detailed method!
1. How to extend the service life of metal bellows
1. Correct selection and installation of metal bellows: Whether the installation is proper or not is directly related to the service life of the bellows. There are many products on the market that must be used. The same bellows can not be mixed at will.
2. Use environment: Try to avoid prolonged exposure to the sun and long-term direct exposure, which may cause the bellows to deform and affect its life.
3. Use skills: Do not use overloaded, the greater the load, the service life of the bellows will be reduced, and it must be used within the allowable range of the bellows and should not be exceeded.
4. Learn to see: look at the craftsmanship, choose high-quality bellows, and check for damage when buying.
2. Specification of metal corrugated pipe joint
1. Type A: One end is a circular arc joint stuck in the female head, and one end is a threaded buckle for internal thread connection.
2. Type B: One end is a groove with two pull-tab male heads, and one end is a threaded buckle connected by an external thread.
3. Type C: One end is a groove with two male tabs, and one end is a bamboo-shaped hose connector.
4. Type D: One end is a groove with two male pull tabs, and one end is a threaded buckle with internal thread connection.
5. Type E: One end is a circular arc joint stuck in the female head, and one end is a bamboo-shaped hose joint.
6. Type F: One end is a circular arc connector stuck in the female head, and one end is a threaded connection with an external thread.
7. DC type: It is a groove with two male tabs, which can be inserted into the circular arc pipe cap plug of the male head.
8. DP type: It is a circular arc plug, also called an internal plug.
9. F type with flange: one section is a circular arc joint stuck in the female head, and one end is a flange connected by a flange.
should pay attention to some aspects when choosing, the first is the choice of joint form, generally speaking, there are flange connection, threaded connection, and quick joint connection. Choose according to your actual needs. The second aspect is pressure. Gathering hoses and joints should be selected according to the actual working pressure, so as to ensure smooth work, and the pressure and temperature that the metal pipe joint can withstand, the corrosiveness of the medium, and so on.
