FONT

Aug 04,2021

The Metal Expansion Joint is a flexible structure installed on the container shell or pipeline to compensate for the additional stress caused by the temperature difference and mechanical vibration. Metal Expansion Joint, as an elastic compensation element that can expand and contract freely, has the advantages of reliable work, good performance, and compact structure. Metal Expansion Joint can be divided into elbow expansion joints, bellows expansion joints and casing expansion joints.

When choosing Metal Expansion Joint, please refer to the following:
State - According to the state of the hose when it is used, refer to the correct use and installation method of the metal hose and the length of the hose during settlement compensation. The length calculation of the various motion states of the hose, the number of bending and the bending radius of the hose, etc. Factors, parameters, choose the length of the hose correctly, and install it correctly.
Size - The nominal diameter of the hose, choose the joint type expansion joint (mainly flange connection, threaded connection, quick connector connection), size, and hose length.
Pressure - According to the actual working pressure of the hose, check the nominal diameter and pressure gauge of the corrugation to determine whether to use the stainless steel mesh sleeve type.
Medium-The chemical properties of the medium conveyed in the hose, according to the corrosion resistance parameter table of the hose material, determine the material of each part of the hose.
Temperature-the working temperature and range of the medium in the hose; the ambient temperature when the hose is working. When the temperature is high, the temperature correction coefficient of the working pressure under the high temperature of Metal Expansion Joint must be used to determine the pressure after temperature correction to determine the correct pressure level.
