Vibration arresters and rubber pipes are used to repel vibrations resulting from the performance of mechanical equipment such as pumps, fans, compressors, etc. They are being used.In addition, these types of joints have the ability to repel the limited movements caused by contraction and expansion. These rubber grippers have less thermal tolerance than metal accordion resistors. The thermal tolerance of this type of stabilizer reaches about 140 degrees Celsius.
On the other hand, rubber anchor joints are best used for low pressure systems (up to 25 bar). In fact, the use of these connections in high-pressure systems is not recommended at all. Among the most important features of rubber grippers that distinguish them from metallic samples are:
- Requires minimum length for installation
- Ability to withstand pressure shocks and repel ram impacts
- Low weight
- High flexibility and low spring coefficients
- Very low heat dissipation
- No need for gaskets and sealing gaskets
- Easy installation
- High resistance against fatigue
- High resistance to abrasion and chemicals
- Failure to transmit electrical currents (used for cathode protection or to transport explosive gases)
- Inner layer: In the stabilizers and rubber tubes, there is an inner layer that is in direct contact with the fluid. Therefore, according to the fluid passing through the pipe, it must have good abrasion resistance.
- Main body: This section of shock absorbers and rubber tubes is mostly made of natural, synthetic or reinforced elastomers by special fabrics (i.e. the “Majid”). The number of layers of this section indicates the ability to withstand the pressure and the mechanical strength of the stabilizer.
- External layer: This section is responsible for resisting atmospheric factors such as ultraviolet radiation, corrosive atmosphere of the junction, wear, blows and mechanical damages, etc. Protect the connections.
Note that the mentioned rubber pipes and stabilizers, due to the placement of the connection and the supports intended for pipelines, will usually be equipped with a number of harnesses. The use of these harnesses makes it possible to adjust the length and control of movements, resulting in uniform pressure dispersion and also increased resistance of the resistor.
Resistors and rubber pipes are divided into two different groups according to the type of baking they have, which we will introduce to you below.
- Blast arresters: In this type, the stabilizers and rubber pipes are placed inside the mold after the initial form and shape.Then the hyperbaric steam enters into the rubber muscles and causes the desired formation and cooking of the stabilizers. In this type, metal molds play a role in creating the form of rubber stabilizers.In addition, we use common presses in rubber baking. Due to the difficulty and complexity of making the belly molds، if the dimensions of the stabilizer change، we need to create a new mold. As you can see in the table, our company is able to offer Blade Stabilizers up to 12 inches.
- Autoclave Grippers: This type of construction method uses metal muscles. Rubber grippers are placed on the metal muscle after initial formation and are driven into the autoclave boiler and cooked.
- In this method, the molds are placed only on the inner surface of the stabilizer and do not include the external surface. For this reason, autoclave molds are cheaper than the types of bladders, and with a small cost the length of the stabilizers can be changed. As you can see in the table, our company can produce autoclave rubber grippers up to 72 inches.
Shock absorbers and rubber pipes made in our company are tested and tested at different stages of construction. After ensuring the production quality, the product test certificate will be issued. Among the most important tests are the following:
- Hydrostatic pressure test up to 1.5 times the design pressure
- Hardness tests
- Bursting Test
- Tensile strength and maximum flexibility
- Ozone Resistance Test
