What Is A Rubber Telescopic Joint Single Sphere?

Rubber telescopic joints Single  spheres  are flexible connectors made of natural or synthetic elastomers, fabrics and, optionally, metal reinforcements. It is designed to absorb the vibration and noise of the pipeline. Various rubber materials are selected according to the type of fluid and usage conditions.

Expansion Joints and Displacement Absorption Fittings

Expansion joint

Expansion joints are pipe joints used to absorb “expansion and contraction in the pipe axis direction” caused by “temperature changes” in pipes for steam, ventilation, gas, water, oil, etc. 1. Sleeve type expansion joints , 2. Bellows type expansion joint, 3. Bend joint.

 Sleeve Type Expansion Joints:

There are two types of sleeve type pipe joints, “single type” and “double type”, but since the “expansion and contraction amount” can be very large, “single type” is often sufficient. There is a “sleeve type expansion joint (HASS 003)” as a single standard. The “sleeve” is a model that expands and contracts by sliding on the “packing part”, and since it has become possible to produce high-quality “packing”, products with features such as high temperature and high pressure, long life, and robustness are commercially available.

Rubber Displacement Absorption Pipe Fitting

Since this joint can be expected to have “elongation” due to the characteristics of “rubber”, the “retraction amount” is smaller than that of the “metal displacement absorption pipe joint”, and the reaction force is also small.

Since the inner surface is continuously smoothed, it can also be used for drainage of sewage. In addition, a large amount of displacement can be obtained, and it is applied to “seismic isolation buildings” and the like. It is difficult to use in “hot water supply piping” because the deterioration of rubber is promoted by “oxidizing action” and “oxidation” is promoted by heat and stress.
