Rubber types used in Rubber Bellow manufacturing
We use all suitable quality Rubbers type in manufacturing of Rubber Bellow as per it’s specification and applicable area. Here is the list of various Rubber types :
- Neoprene : For applications where moderate oil resistance, weather protection and mechanical strength are important.
- EPDM : This is widely used due to its excellent resistance to environmental exposure, flexibility and cost-effectiveness.
- Natural : Used primarily for its excellent elasticity, tear strength and vibration-damping properties.
- Silicon : Excellent for high-temperature resistance, flexibility, and bio compatibility. Suitable for cleanliness, thermal stability & weather resistance.
- Hypalon : It’s outstanding resistance to weathering, chemicals, heat and ozone – making it ideal for demanding environments.
- Nitrile : Used primarily because of its excellent resistance to oils, fuels and greases, along with good mechanical properties.
- Buna-N : Used because of its excellent resistance to oils, fuels and other petroleum-based fluids, combined with good mechanical strength and durability.
Flange materials used in Rubber Bellow manufacturing
Both side flanges fitted in Rubber Bellow are made from metals or composite materials to provide structural rigidity. Common materials are :
- Mild steel : Offers excellent weldability and strength, making it a popular choice for supporting structures.
- Stainless steel : Known for its corrosion resistance and strength, ensuring longevity in various environmental conditions.
- ASTM A105 : A standard specification for carbon steel forged fittings, providing good mechanical properties and weldability.
- SA516 Gr.70 : This carbon steel plate is known for its excellent weldability and notch toughness, ideal for pressure vessels.
Rubber Expansion Bellows supplier
Royal Engineering Corporation is the OEM supplier of Rubber Expansion Bellows which are typically employed in piping systems for liquid or gas transportation. They are particularly beneficial in systems subject to thermal stress, as they can absorb the expansion caused by temperature fluctuations. We supply Bellow for the following industries :
- Steel plants : Rubber Bellows helps to manage thermal expansion and contraction in piping systems.
- Cement plants : The Bellow ensures flexibility in conveyor systems that deal with heavy loads.
- Boiler plants : Rubber made Bellow provides a solution for thermal expansion in steam systems.
- Thermal power plants : The Bellow made of Rubber absorbs vibrations from machinery to protect piping.
- Petro-Chemical refineries : Bellows allow movement in the complex piping of chemical processes.
- HVAC systems : Bellow facilitates the handling of movement and shock absorption in duct work.
- Environmental systems : A Bellow used in waste management systems to withstand pressure variations.
- Chimneys : Bellows provides flexibility in exhaust systems, accommodating thermal changes.
- Water pipelines : The Bellow reduces stress on joints in high-pressure water systems.
- Fertilizer units : Rubber Bellow assists in the smooth operation of chemical delivery systems.
Optional accessories supplied with Rubber Expansion Bellows
To maximize the effectiveness of Rubber Expansion Bellows, several optional accessories can be supplied as per requirement. Here are some important accessories are :
- Counter flange : It creates a secure joint between the bellows and adjoining pipes, facilitating a tighter seal.
- Matching flange : It designed to align perfectly with the pipework, promoting seamless integration and reducing installation complications.
- Companion flange : These allow for easy connection to adjacent equipment, ensuring that the Bellow can function optimally with various systems.
- Split retaining rings : These rings help maintain the positioning of the Bellow, preventing excess movement that could lead to damage.
- Control units : Tie Rods & Nuts provide additional stability, ensuring that the Bellows can handle the pressures & movements.
- Revolving flange : It allows for easy installation and maintenance, ensuring a secure connection between the Bellow and the adjoining pipeline.
- Loose flange : This type of flange provides flexibility in installation, accommodating various pipe dimensions and alignment issues.
- Gaskets : Essential for preventing leaks, gaskets seal the joints between the Bellow and flanges, enhancing the overall effectiveness of the system.
- Fasteners : Bolts, Nuts & Washers are crucial for securing the entire assembly. Proper fastening ensures the stability and safety.
