Material selection and use of expansion device

In Telescopic device In the process of increasingly extensive application, because of the different environmental location, the conditions to be met are also different, the use of expansion joint in drainage pipeline and supply pipe is different, and the use of expansion joint in high temperature pipeline and high pressure pipeline is also different. Therefore, when using the expansion device, we should consider it in detail. A suitable expansion device is good for the pipeline, such as displacement compensation, anti vibration and noise reduction, but the application of an inappropriate expansion device in the pipeline will burden the pipeline. So what are the advantages and disadvantages of different telescopic materials? How to choose?

A good kind is carbon steel. The expansion joint produced is commonly used. It is very convenient to use, and it is very convenient to use as the accessories of pump valve. Strength, heat resistance is commonly used in several materials in a good one.

The second is the expansion device made of stainless steel. The price of this kind of expansion device is not so high. The material of stainless steel is extensive, so it is widely used. There are many kinds of stainless steel materials, which have different advantages and disadvantages, so the price varies from high to low. However, it is recommended not to buy inferior stainless steel expansion device, which is not good for the pipeline, but has a burden on the pipeline.

Another is ball milling Cast iron expansion joint This kind of expansion joint is also commonly used. However, due to the sand turning process, it is easy to have sand holes and water leakage. If conditions permit, it is better to use steel expansion or stainless steel expansion, after all, the comprehensive performance and cost performance are good.

    Shanghai Huanjing pipeline equipment factory has strong technical force, excellent production equipment and sound quality inspection means. On the basis of widely absorbing the advantages of similar products at home and abroad, we boldly adopt new technology and new technology to make the products more suitable for the installation under different environments in various regions of China, which brings great convenience and benefits to the design, construction and maintenance of the project, and with its high quality and real price Reputation is welcomed and trusted by users.
