When we buy soft rubber expansion joints, and how we can get superior quality rubber joint products?
Liwei flexible rubber joints manufacturers to tell the user four reference factors:
1, status.
Press Flexing state rubber joints when used with reference to the proper use of rubber joints rubber joint best installation method and length of time of the settlement of compensation, the length of the hose to calculate the minimum number of bends and various hoses and minimum bending motion state factors radius, select the correct length parameter rubber joints, and correctly installed.
2 medium.
When the medium rubber joints in the transport of corrosive chemicals when, according to the corrosion resistance of the rubber material parameter table, determine the type of rubber used in rubber joints.
3, the pressure.
The actual working pressure flexible rubber joints according to the song, and then check the connector nominal diameter and pressure gauges to determine whether the use of stainless steel mesh cover types.
4, the temperature.
Flexing the operating temperature range and medium rubber joints; When high temperatures are required Flexing temperature correction factor working pressure rubber joints under high temperature, pressure and temperature corrected to determine to determine the selection of the correct pressure level.
