Rubber tubing is a versatile tubular product expertly crafted from high-quality rubber. It typically features a robust inner and outer rubber layer, along with a reinforcing skeleton layer, ensuring durability and reliability. This tubing is designed to transport gases, liquids, slurries, or granular materials efficiently. The core function of rubber tubing lies in its ability to facilitate the seamless transmission of media through its exceptional elastic sealing and pressure-bearing capabilities. This makes it an essential component widely utilized across various fields such as industry, automotive, and medical treatment.
1. Introduction of rubber pipe material
Crude rubber Known for its exceptional high elasticity and superior wear resistance, crude rubber is adept at handling bending and scratching, making it ideal for low-pressure environments.
Protobutadiene rubber (SBR) This rubber is celebrated for its excellent wear resistance and cost-effectiveness, though it does have limitations in oil resistance.
Cis-polybutadiene (BR) Exhibits impressive moisture resistance and outstanding low-temperature resilience, remaining elastic even at -50ºC.
Nitrile rubber (NBR) Boasts excellent oil resistance, particularly against mineral and lubricating oils, yet it shows weaker ozone and high-temperature resistance.
Chloroprene rubber (CR) Offers a balanced performance with resistance to oil, ozone, and aging.
EPDM Rubber (EPDM) Renowned for high temperature resistance ranging from -50 to 150ºC, along with strong weather resistance, making it suitable for prolonged outdoor exposure.
Fluorinerubber (FKM) Excelling in high temperature resistance from -20 to 250ºC and remarkable chemical corrosion resistance, it is perfect for extreme environments.
Silastic (VMQ) Exceptional high temperature resilience from -70 to 300ºC, high transparency, and excellent electrical properties make it a premium choice.
Chlorinated sulfated polyethylene rubber (CSM) Exhibits robust resistance to strong acids and alkalis, such as concentrated sulfuric and nitric acids, and offers superior permeability resistance.
Conductive rubber Integrates conductive fibers or metal mesh, effectively preventing the accumulation of static electricity.
Fire retardant rubber Enhanced with flame retardants like aluminum hydroxide and compliant with the UL 94 flame retardant certification for added safety.
2. Structural composition of the rubber pipe
The glue layer This crucial component is in direct contact with the conveying medium, providing essential wear, corrosion, and resistance to oils, acids, and alkalis.
| casing pyl |
Enhance the strength of the tube body, including cotton thread, steel wire, synthetic fiber, etc., to determine the pressure bearing capacity (e. g., the steel wire woven layer can withstand 80~600MPa pressure). |
| External glue layer |
Protect the internal structure from the external environment (such as ultraviolet light, mechanical friction). |
3. Structurally, rubber pipes are ingeniously categorized into various types, including sandwich hoses, braided hoses, winding hoses, and full hoses, each designed for specific applications.
4. Working principle of rubber pipe
| Pressure transmission and energy buffer |
The hydraulic hose transfers the force through the fluid pressure, and uses the elastic shape of the rubber to absorb the pressure pulsation, and reduce the vibration of the system. For example, the hydraulic pipe of construction machinery bears high pressure (up to 60MPa or above) through a multi-layer steel wire reinforced layer. |
| Shock absorption and displacement compensation |
Rubber soft connection (e. g., flexible rubber joint) absorbs pipe displacement through the elastic deformation of the curtain layer and wire ring to reduce operating noise, which is suitable for pump valve connection and frequent vibration line. |
| Media isolation and leakage prevention |
The compactness of the inner adhesive layer combines with the protection of the outer adhesive layer to prevent the leakage of water, gas or chemicals. For example, the mobility of the coolant between the car radiator and the engine. |
5. Application areas:
| industrial circle |
Welding gas delivery, hydraulic system, mine ventilation. |
| automotive filed |
Coolant circulation, fuel transmission, air-conditioning system. |
| Medical field |
Infusion tube, surgical instrument catheter. |
| The field of agriculture |
Irrigation system, aquaculture equipment. |
| New energy field |
Automobile battery and wind turbine cooling system, etc. |
6. Standardization and security guarantee:
| high-voltage insulation test |
Burst pressure is 3 times the working pressure (such as hydraulic hose). |
| degradation testing |
Simulated high temperature / UV environment assessment life (theoretical value of more than 15 years). |
| Environmental requirements |
Biological based rubber and low VOC (volatile organic compounds) formula meet the sustainable development needs. |
Leverage state-of-the-art production equipment and rich technical expertise to soak up rubber and plastic products, offering customized specifications and materials for a diverse range of rubber products.
