Flat flange for pressure level is relatively low, the pressure fluctuation of.Bs10 T/D Flange flange pipe system vibration and shock are not serious in the category of flat flange, we mainly based BS10:1962 series of flange, we also do the United States, Japan, Britain, Germany, a series of products. We have strict quality management system, won a lot of customers, the company obtained three national patents. Wish our customers came to negotiate.
