The steel expander of water pipeline is an important pipe fitting, which is used to compensate and absorb the axial, lateral and angular displacement of the pipeline, and at the same time, it can effectively isolate vibration, reduce noise and ensure the safe operation of the pipeline. So, how to choose and maintain the steel expander of the water pipe?
1. Selection. 1.Material: The material of the steel expander should meet the relevant standards, with sufficient strength and corrosion resistance to ensure its long-term stable operation. When purchasing, you should pay attention to the quality certification documents and material identification of the product.
2.Specifications: According to the diameter, length, working pressure and other parameters of the pipeline, select the appropriate retractor specifications. When purchasing, the operating requirements and working conditions of the pipeline system should be fully considered to ensure that the specifications of the expander match the actual needs.
3.Structure: The steel expander structure should be reasonable, easy to install and maintain. When purchasing, you should pay attention to check whether the structure of the retractor is compact, simple and easy to operate.
4.Brand reputation: Choose products from well-known brands, you can use them with more confidence. When purchasing, you can refer to user evaluations and recommendations from professional organizations to choose a brand with a good reputation and reputation.
