What is the performance of the steel expander

Expanders are mainly used for valves, pipelines and other equipment between the pipe system connection parts that provide z for the required pressure retraction when the pipeline is working. Installation, maintenance, pipeline expanders can also be used for expansion, through the pipeline to compensate and expansion of the installation pipeline temperature and displacement changes in the force generated.
The expander is a very important part of the piping system, usually connected together, so it must have good corrosion resistance, which is especially important for the expander. If an expander does not have good corrosion resistance, it will not work properly. When the expander is flushed by liquid or gas, the expansion tube will produce abnormal vibration, which will affect the normal operation of the pipeline and cause great safety hazards. Therefore, in order to avoid the above situation, the expander must have good corrosion resistance and good service life so that it can play a greater role. The expansion performance of the expander refers to the expansion of the pipe when the metal expander expands and contracts. Its size is determined by the expansion volume. When the expansion volume reaches the requirement, the length and shape of the expander can be chosen according to the user's need. In the process of product production, quality control must be carried out at each stage to ensure good product quality and service to meet the needs of customers, so as to improve the competitiveness of products. We also need to choose different types of products according to their performance and meet different usage requirements. When the product quality is not good, it will affect the normal operation in the whole market and cause serious impact to the customers! Therefore, we must choose the good quality of the telescope to improve the use of the product!
