Anti-slip Flange

The price of a sliding flange or so flange is usually lower than that of a welded neck flange, so it is a popular choice for our customers. However, customers should keep in mind that the additional cost of properly installing the two angle welds required may reduce initial cost savings.
In addition, the sliding flange under pressure of the welded Farambi has a higher life expectancy. The sliding flange usually has a neck and has a straight hole, and the pipe will pass completely through. The installer slides the flange to the end of the pipe and locates the flange so that the angular weld between the neck and the pipe, as well as the Franconne angle weld between the end and the flange hole, will be fixed and sealed.
The connection to the pipe is done through 2 angular welds, also on the outer side and inside the flange. One drawback of flanges is that, in principle, pipes must always be welded first, and then welded. The combination of flange and elbow or flange and three-way is not possible because the named accessory does not have a straight end and completely slips into the sliding flange.
