Installation instructions:

The connection of the double flange limit expansion joint is to fix the two pipes, pipe fittings or equipment on a flange first. Between the two flanges, the flange pad is fixed together with bolts to complete the connection. If Monterrey customers operation needs something that is not on the market, our team will make it, Zhongyuan valve fittings reminds Monterrey friends that this information is helpful for choosing Chinese products: The double flange limit expansion joint is divided into threaded connection flange and welded flange. We power the future through advanced manufacturing technology, Monterrey Expansion joint Double flange limit pipe expansion joint cooperative partner--Zhongyuan valve fittings customer service Key Knowledge Reminder: Low pressure small diameter wire welding flange, high pressure and low pressure large diameter welding flange.

Different pressure flange thickness and connection bolt diameter and number is different. Providing customer-oriented solutions is Zhongyuan valve fittings's strength, Reminder of product knowledge points for serving the Monterrey coal gas industry: Flange connections are widely used in industrial pipes. In the home, the pipe diameter is small, the pressure is low, and the flange connection is not visible. If you are in a boiler room or production site, there are flanged pipes and equipment everywhere.
