What exactly should I pay attention to in the installation of flexible rubber flexible joints?

Flexible rubber flexible joints soft connection due to temperature changes caused by the change of material measurement elements. The expansion coefficient is the slope of the expansion-temperature curve, the instantaneous expansion coefficient is the slope at a specific temperature, and the uniform slope between two specified temperatures is the uniform thermal expansion coefficient. The expansion coefficient can be expressed in terms of volume or length, usually in terms of length. The density of a substance is the mass per unit volume of that substance in kg/m3 or 1b/in3. When a force is applied to a flexible rubber joint flexible connection per unit length of prism can cause a unit change in the length of the object, the force required per unit area is called the modulus of elasticity. The unit is 1b/in3 or N/m3. the heat required to change the temperature of a unit mass of material by 1 degree.
The values of specific heat are the same in both the British and CGs systems, since the unit of heat (Biu or cal) depends on the amount of heat required to raise the temperature of a unit mass of water by 1 degree. The value of specific heat in the International System of Units is different from that in the Imperial or CGS systems, because the unit of energy (J) is set according to a different definition. The units of specific heat are Btu (1b-0F) and J/(kg -k). The measurement of the rate of thermal conductivity of flexible rubber joints. In the unit cross-sectional area of the material to establish a temperature gradient of 1 degree per unit length, then the thermal conductivity is defined as the unit moment of heat conduction, the unit of thermal conductivity is Btu/(h-ft-0F) or w/(m -K).
 
Intergranular corrosion resistance than good, with stronger chemical corrosion resistance, compared with conventional stainless steel, with higher ductility, stress corrosion resistance, compressive strength and high temperature resistance. With high resistance to pitting, crevice corrosion, stress corrosion and uniform corrosion ability, flexible rubber soft joints soft connections have high strength and excellent resistance. Flexible rubber joint soft connection can be divided into two categories: flexible rubber joint soft connection and welded flexible rubber joint soft connection. If the shape of the cross-section can be divided into round and shaped tube, the most used is the round flexible rubber joint soft connection, but there are also some square, rectangular, semi-circular, hexagonal, equilateral triangle, octagonal and other shaped flexible rubber joint soft connection. If it is used to receive fluid pressure flexible rubber joint soft connection, before use must be hydraulic pressure test to check its pressure resistance and quality, as long as the specified pressure does not occur under the leakage, wetting or swelling for qualified, part of the flexible rubber joint soft connection also according to the specifications or requirements of the rolled edge test, flare test, flattening test, etc.
