Banjo Elbow Suppliers Explains How Expansion Joints Work


    Banjo Elbow Suppliers describes how expansion joints work:

    1. If the expansion joint is leaking, cracked, bulging, the joint card is corroded, the steel wire is broken, and the expansion joint layer is aging and cracked, replace it immediately. When the expansion joint is stored, the two ends of the expansion joint are tightly sealed to prevent debris from entering the expansion joint. The large-diameter expansion joint assembly should not be used at a radius smaller than the expansion joint to a small bending radius to avoid bending or bending near the joint, otherwise it will hinder the hydraulic transmission and conveying of materials or damage the expansion joint assembly.

    2. It is very important to determine the length of the expansion joint you need, and it should also be checked whether the operating conditions of the expansion joint meet the requirements of the selected expansion joint. It should be ensured that the expansion joints you will be using are correct. Working pressure and suction values ​​should be determined carefully. In particular, it should be noted that sudden pressure changes or pressure peaks exceeding the allowable value will greatly shorten the life of the expansion joint. The ends of the expansion joint cannot be continuously submerged in the conveyed substance.

    3. Inspect expansion joints after each use to ensure that there is no structural damage. Hydraulic testing is recommended if the expansion joint is subjected to severe stress during use or if the outer layer of the expansion joint will be in contact with the liquid being conveyed for a prolonged period of time. When the expansion joint is connected straight, ensure that the sub has enough slack so that the expansion joint can adjust itself when the length changes under pressure.
