How to distinguish the merits and demerits of pipeline expansion device

Pipeline in the market Telescopic device There are various types and uneven quality. It is not easy to choose high-quality professional manufacturers among the various types of expansion devices. Next, Shanghai Huanjing Technology Department will make some specific industry disclosure on this issue.

    Pipe expander After the arrival of pipeline products, customers generally need to conduct on-site inspection, and experienced customers will judge the quality of the expansion joint through sound, appearance, hand feeling and other aspects.

1. Hit the shell of the expansion device by hand. If the sound is dull, generally speaking, the material of the expansion device is better. This is because if the thicker the structure of the expansion device, the heavier the sound will be, and the greater the degree of pressure it will bear.

2. Look at the surface of the expansion device to see if there has been any feeding phenomenon or whether the mortar has been applied. If this situation occurs, it is very likely that the secondary maintenance of the expansion joint is caused. If this situation is installed on the pipeline, there will be many hidden dangers. It is suggested that we should not be greedy for small and cheap, and use similar products that have been repaired.

3. Touch the cutting surface by hand. Generally, the blade pattern of high-quality telescopic device is relatively neat and not uneven. Because the professional production of expansion of the lathe cutter surface cut out of the cross-section is relatively flat, Shanghai Huanjing production of pipeline expansion section is flat, in line with the provisions of ~ standard.

4. Direct measurement of hole spacing is only an intuitive method to see if it meets the installation requirements. Due to the small installation error of the CNC system, the installation of your products will be limited to a large range of equipment, which will be able to meet the actual installation requirements.

Since its establishment, Shanghai Huanjing pipeline equipment Co., Ltd. has always adhered to the business philosophy of "taking science and technology as the guide, regarding quality as life, and regarding users as God", adhering to the product quality policy of striving for improvement, and specializing in R & D and production of various products and equipment. Our company adheres to the enterprise spirit of "innovation, excellence, unity and dedication", casting a batch of high-quality and excellent performance products, which have been unanimously praised by new and old customers.
