Method for avoiding leakage of rubber expansion joint
Method for avoiding leakage of rubber joint：Please use the butterfly valve special flange!
The selection of the peer to peer flange is to give the perfect, durable and safe connection method;
Please use the following selection of pipe silp on flange standard .
1, the inner diameter of the pipe crossing joints must be the same with the inner diameter of the rubber expansion joint.
2, the flange contact surfaces must be smooth and flat in order to ensure maximum sealed space. (Shown below), when the rubber expansion joints do not close engagement with the pipe crossing the contact surface, there will be noise generated, and there will be less pressure, and water leakage phenomenon.
