Rubber tubing is a versatile tubular product crafted predominantly from high-quality rubber, typically comprising an inner rubber layer, an outer rubber layer, and a robust skeleton layer. This essential conduit is designed to efficiently transport gases, liquids, slurries, or granular materials. The primary function of rubber tubing is to facilitate the seamless transmission of media through its remarkable elastic sealing and pressure-bearing capabilities. It enjoys widespread application across a diverse array of fields, including industry, automotive, and medical treatment.
1. Introduction of Rubber Pipe Material
Crude Rubber: Known for its extraordinary elasticity, wear resistance, and excellent bending and scratching characteristics, crude rubber is highly suitable for use in low-pressure environments.
Protobutadiene Rubber (SBR): With its superb wear resistance and economical cost, SBR is an attractive option, though it offers limited oil resistance.
Cis-polybutadiene (BR): Renowned for its exceptional moisture resistance and outstanding low-temperature resilience, remaining flexible and elastic even at temperatures as low as -50ºC.
Nitrile Rubber (NBR): Exhibits remarkable oil resistance, capable of withstanding mineral and lubricating oils; however, it has limited ozone and high-temperature resistance.
Chloroprene Rubber (CR): Balances oil resistance, ozone resistance, and aging resistance, offering a comprehensive performance package.
EPDM Rubber (EPDM): Resilient to high temperatures ranging from -50 to 150ºC and boasts strong weather resistance, making it ideal for prolonged outdoor exposure.
Fluorine Rubber (FKM): Exceptionally resistant to high temperatures (ranging from -20 to 250ºC) and chemical corrosion, making it suitable for extreme environments.
Silastic (VMQ): Designed to withstand high temperatures (from -70 to 300ºC), it features high transparency and outstanding electrical performance.
Chlorinated Sulfated Polyethylene Rubber (CSM): Offers robust resistance to strong acids and alkalis, such as concentrated sulfuric and nitric acids, along with formidable permeability resistance.
Conductive Rubber: Incorporates conductive fibers or metal mesh to effectively prevent static accumulation.
Fire Retardant Rubber: Enhanced with flame retardants like aluminum hydroxide, it has successfully passed the stringent UL 94 flame retardant certification.
2. Structural Composition of the Rubber Pipe
The Glue Layer: This layer is in direct contact with the conveyed medium and is engineered for wear resistance 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 categorized into various types, including 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. |
