Flange type rubber flexible connection thermal expansion and contraction basic concept

Flange type rubber soft connection goods have high compressive strength and compressive strength, and its soft confinement performance indicators, easy handling and loading and other effects, is widely used in metallurgical industry. Power installation projects. Chemical enterprises. To the pipeline and sewage treatment and other industries, the role of centrifugal water pump in the pipeline and the pipeline is the middle of the connection. Flange type rubber soft connection in the pipeline operation has a certain multi-directional deviation in the pipeline operation due to thermal expansion and cold contraction.
Therefore, the flange type rubber soft connection can relieve the blind driving force in the pipeline operation, a certain amount of maintenance of the pipeline, especially the installation and maintenance of the pipeline, very convenient and fast. In the pipeline connection is to have its a role together, the operation of the pipeline plays a role in the expansion joint compensation offset, because they have this correlation in the pipeline connection, so they can have a close connection in the actual operation of the pipeline connection. Flange type rubber soft connection interchangeable alternative role, only in the unique case selected a certain specification type product series pipe fittings coupling head use. The following will be related to the basic concept of monoflange flange type rubber soft connection Rashen.
 
1 . Flange type rubber soft connection can be axially offset: can be axially smaller or stretch; offset large, can eliminate the pipeline due to seasonal changes or the chemical substances (such as boiling water. Steam) is not the same and the thermal expansion and contraction stress field. Maintenance of machinery and equipment. Shut-off valves. Inner dashboard and piping.
2 . Flange type rubber soft connection can be circumferentially eccentric: flange type rubber soft connection can be eccentrically moved in all directions around, solving the difficulty of different heart when installing the pipeline, avoiding damage caused by basically moving down. In addition, flange type rubber soft connection products in the operation of the pipeline has a certain multi-directional deviation role, the pipeline in operation due to thermal expansion and cold contraction and very important expansion joint compensation role.
3 . The system can transmit the driving force of the blind when starting the pump to all parts of the pump and pipeline based on the force transfer foot screw, avoiding the driving force concentrated in the corner of the pipeline or the far side of the pump, resulting in impact force endangering mechanical equipment, and playing the role of expansion joint compensation deviation for the operation of the pipeline.
