 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.
