Rubber Bellows Kits

About Rubber Bellows Kits

Rubber bellows kits usually consist of two main parts: bellows and flange. Bellows are pipe sections made of corrugated structures that are capable of bending and twisting in a piping system to accommodate different installation needs. Flange is the part that connects corrugated pipes and other pipe components. It is usually made of metal materials and has the functions of fixing and sealing.

Main Functions

1. Absorb vibration and noise: Rubber bellows can reduce vibration and noise in the pipeline system, making the system more stable and quiet.

2. Compensate displacement: Due to the flexibility and scalability of rubber bellows, it can compensate for displacement and deviation in the pipeline system to avoid stress concentration and rupture.

3. Withstand pressure and temperature changes: Rubber bellows has good elasticity and high temperature resistance, can withstand pressure and temperature changes in the pipeline system, and maintain the sealing performance of the system.

4. Simplify installation and maintenance: The rubber bellows kits have a simple structure and is easy to install, which can reduce installation time and cost. At the same time, its maintenance and replacement are relatively easy.

Application Areas

1. Industrial pipeline system: Rubber bellows kits are commonly used in industrial pipeline systems, including water supply pipelines, water supply and drainage pipelines, chemical pipelines, oil pipelines, natural gas pipelines, etc. They can be used to connect different pipe elements, compensate for pipe movements, absorb vibrations and noise, and are resistant to corrosion and high temperatures.

2. HVAC system: In HVAC systems, rubber bellows kits are often used to connect equipment such as air ducts, exhaust ducts, and air conditioning units. They reduce vibration and noise in the system and are resistant to high temperatures and corrosion.

3. Automobile industry: In the automobile industry, bellows kits are widely used in exhaust systems, oil supply systems, cooling systems, etc. They can connect different exhaust pipes and fittings, absorb engine vibration and thermal expansion of the exhaust pipe, and are resistant to high temperatures and oil.

4. Food processing industry: In the food processing industry, bellows kits are often used in food handling and conveying systems. Due to its compliance with food safety standards, it can provide sealing and connection functions during the transfer of liquids, powders or gases.

5. Medical equipment: Rubber bellows also have certain applications in medical equipment, such as ventilators, infusion equipment and blood circulation systems. They provide connection and sealing functions while being flexible and durable.

Certification Standards

1. ISO certification: The International Organization for Standardization (ISO) has issued a series of standards related to rubber products, such as ISO 9001 and ISO 14001. Our rubber products have passed ISO14001:2015 and ISO9001:2015 certification, which can ensure that rubber manufacturing meets the requirements of international standards and provides consistent product quality and reliability.

2. IATF certification: The rubber bellows kit has passed the IATF16949:2016 certification. The rubber products under this certification comply with international quality management.

3. FDA certification: FDA certification ensures that products meet food safety and medical device safety requirements to ensure their safety for human health. And obtain formula certifications such as UL/NSF/KIWA/MPA.

How to Ensure Quality for You

Quality control

✭Molding random inspection
In the molding section of the process, the products produced by molding are randomly inspected in a timely manner, and the products in the process are mainly inspected for first article inspection/process inspection/final article inspection. Quality control is carried out in the early stage to prevent defective products from entering the next process to ensure product quality and delivery time.

✭Measurement Center
The measurement center has a strong measurement team, which is responsible for the management of the company’s measurement equipment, including equipment use supervision, annual maintenance, calibration, repair, and measurement personnel ability assessment, etc. Serve the measurement needs of the manufacturing process, use important instruments to measure and provide measurement data in a timely manner, including product appearance/size/physical properties, etc.

The main instruments include:

✭Automatic quality inspection
In order to meet the ppm requirements for appearance and ensure that the dimensions of O-rings and washers are 100% within specification values, the company invested in more than a dozen automatic quality inspection machines imported from Italy to automatically calculate CPK values without human error.

✭Manual quality inspection
We have a group of professional and experienced senior product inspectors with more than ten years of experience. They are mainly responsible for product mold inspection, manual deburring, full inspection, etc. The first-time pass rate of quality inspection is as high as 90%, meeting the requirements of manufacturers in various industries.

Instructions for use

■ Installation preparation
1. Before installation, check the appearance and size of the rubber bellows kit to ensure there is no damage or deformation.
2. Clean and check the flange surface of the connecting pipe to ensure that the surface is smooth, clean and free of any impurities.
3. Check the connecting flanges and bolts of the kit to ensure they fit and comply with relevant standards.

■ Installation process
1. Connect one end of the rubber bellows kit to a flange and secure it to the flange using appropriate bolts.
2. Align the flange at the other end with the flange of the target pipe and tighten it with bolts.
3. According to the recommended torque value provided by the manufacturer, tighten the bolts gradually and alternately to ensure that the flange connection is even and tight.

■ Precautions for use
1. During use, avoid excessive bending, twisting or stretching of the rubber bellows kit to avoid damaging its structure and performance.
2. Ensure that the working pressure and temperature of the piping system do not exceed the rated value range of the bellows kit.
3. Regularly check the appearance and connections of the rubber bellows kit to ensure there are no damages, cracks or loose bolts.
4. Avoid exposing the rubber bellows kit to harmful chemicals, solvents or high temperature environments to avoid affecting its performance and life.
5. If any abnormality or damage is found, repair or replace it in time.
