1.What is the media of rubber expansion joint?
Common type used to transport -15 to 120 centigrade, of air, compressed air, water, sea water, oil,
acid and alkali. Special type used to transport -30 to 250 centigrade of the medium contain oil, strong
alkali acid concentration, solid-state materials
2.What is the function of rubber expansion joint?
Rubber (or elastomeric) expansion joints provide a wide range of elastomers (rubbers) and reinforcements depending on the pressure required. They isolate noise and vibration and are sometimes lined with
Teflon for extra chemical resistance. Rubber expansion joints protect piping systems from damage
caused by vibration and movement.
3.How to Measure a Rubber Expansion Joint?
Heating and cooling causes many materials to expand and contract, often with a noticeable effect. This
expansion and contraction can cause damage to a system; for instance, if a pipe system in a factory
transporting hot materials were to expand too much, it could crack the pipes. Rubber expansion joints
are flexible pieces that allow materials, like pipes, to expand and contract safely without damage.
When these joints tear or deteriorate, you need to measure for a new joint.
4.How to Install Rubber Expansion Joints?
Rubber expansion joints are installed in piping systems to reduce stress caused by thermal expansion
and contraction that would otherwise rupture the pipe joints. Rubber expansion joints ease the
pressure of misaligned connections, which occurs after parts begin wearing, when pipes settle, and
from mechanical operations of equipment in the system. Installing expansion joints saves companies
money on annual repairs. They are an integral part of any major pipe system, and require a team
of professional to install, especially when the pipe system is very large.
5.How to design expansion joint?
Geographic and climatic conditions play a vital role in the preliminary design decisions. Intelligent
use of raw materials is also a key consideration. Expansion joints must also withstand pipeline
shift variations caused by physical displacement during the manufacturing process, or through
natural phenomenon such as earthquakes or severe weather. Construction must also resist
pressure, vacuum, thermal and chemical reactions to internal fluids or gas, as well as external
corrosive influences. Before our engineers touch pencil to paper, these factors are meticulously
reviewed and evaluated.
6.How many types does rubber joint has?
1)Single sphere rubber expansion joint
2) double sphere rubber expansion joint
3) threaded rubber expansion joint
4) reduced rubber expansion joint
5) rubber bending joint
