Rubber joint length is not enough when installation?Often appear in the process of site construction, the standard length of rubber joint length is not enough, from the pipeline on both sides of the interface short 20 mm to 50 mm, less than 20 mm can through the rubber joint of tensile elastic characteristics, but there is a limit of the length of the stretching, the limit length is used to pull the rubber joint bad completely, or rato.In this case?
Rubber joint on both sides of each have two pieces of the flange, flange is normal in the middle of the two pieces of rubber joint when installation, must be included in the two flange is outside in order to expand the rubber joint length and add up to the edge of the rubber joint between the two flanges, ACTS as the rubber gasket, but the rubber gasket is very cow, two pieces of flange length can according to need to adopt the appropriate thickness, if add two slices after or not long enough, or is there a way to, can be in the end or ends plus flange, flange and flange can be used in a rubber gasket to fill, to prevent leakage.
