Rubber tubing, an engineered marvel primarily crafted from durable rubber, typically includes an inner and outer rubber layer, complemented by a robust skeleton layer. This versatile product is designed to expertly transport gases, liquids, slurries, or granular materials with precision. At the heart of its functionality lies its ability to seamlessly transmit media through its exceptional elastic sealing and pressure-bearing capabilities. Favored across diverse fields such as industry, automotive, and medical treatment, rubber tubing stands as a fundamental component, ensuring efficient and reliable performance in myriad applications.
1. Introduction to Rubber Pipe Material
Crude Rubber - Exhibiting remarkable high elasticity, wear resistance, and exemplary bending and scratching characteristics, this material thrives in low-pressure environments.
Protobutadiene Rubber (SBR) - Known for its outstanding wear resistance and cost-effectiveness, although it offers limited oil resistance.
Cis-Polybutadiene (BR) - Renowned for its superior moisture resistance and exceptional low-temperature resilience, maintaining elasticity even at -50ºC.
Nitrile Rubber (NBR) - Distinguished by its superior 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 oil and ozone resistance along with commendable aging resistance.
EPDM Rubber (EPDM) - This high-performance material withstands high temperatures ranging from -50ºC to 150ºC and exhibits strong weather resistance, making it ideal for prolonged outdoor exposure.
Fluorine Rubber (FKM) - Exceptional for its high-temperature resilience from -20ºC to 250ºC and chemical corrosion resistance, perfectly suited for extreme environments.
Silastic (VMQ) - Celebrated for its wide high-temperature range from -70ºC to 300ºC, coupled with high transparency and excellent electrical performance.
Chlorinated Sulfated Polyethylene Rubber (CSM) - Resilient against strong acids and alkalis, such as concentrated sulfuric and nitric acids, with excellent permeability resistance.
Conductive Rubber - Engineered with built-in conductive fibers or metal mesh, effectively preventing static accumulation.
Fire Retardant Rubber - Enhanced with flame retardants like aluminum hydroxide, earning recognition through UL 94 flame retardant certification.
2. Structural Composition of the Rubber Pipe
The Glue Layer - Acts as a frontline defender, directly contacting the conveyance medium while offering superior wear and corrosion resistance, including oil, acid, and alkali resistance.
| 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, such as sandwich hoses, braided hoses, winding hoses, and full hoses.
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. |
Harness the power of cutting-edge production equipment and extensive technical expertise to craft and customize a wide array of rubber and plastic products, tailored to a variety of specifications and materials.
