Counterflanges, Sealings, Coupling Material

To ensure complexity of supplies we are offering counterflanges as complementary assortment to all flow meters manufactured by our company. In the supply there are 2 pieces of counterflanges in finish PN40, PN25 and PN16, screws, nuts and sealings. Flanges are made from material grade 11416 or 17248. Standard sealing is of ECONOGRAPH material (water, steam). On request we are able to delivery sealings of TEMAFAST material (for gases), TEMAPLUS (oils), TEFLON (chemicals), or other kinds of sealings (copper etc.)

The table below states standard dimensions of flanges in compliance with EN 1092-1. If the customer wishes to get supply in compliance with other standards (such as ASME, GOST, ČSN, etc.) our company shall send you a precise technical specification of the supply in our offer.
