Rubber tubing represents an essential innovation in transporting various substances. This remarkable tubular product, crafted primarily from high-quality rubber, features a robust inner and outer layer, coupled with a sturdy skeleton layer. It plays a pivotal role in conveying gases, liquids, slurries, or granular materials, ensuring effortless and efficient media transmission. Leveraging its elastic sealing and pressure-bearing prowess, rubber tubing finds extensive application across diverse sectors, including industry, automotive, and medical fields.
1. Introduction of rubber pipe material
Crude rubber Renowned for its remarkable elasticity, crude rubber offers excellent wear resistance, and adaptability to bending, making it ideal for low-pressure environments.
Protobutadiene rubber (SBR) This cost-effective option boasts exceptional wear resistance, although its oil resistance might not be as robust.
Cis-polybutadiene (BR) Enjoys superior moisture resistance and maintains elasticity even at -50ºC, making it perfect for low-temperature settings.
Nitrile rubber (NBR) Outstanding in oil resistance, particularly against mineral and lubricating oils, though it has limited ozone and high-temperature resistance.
Chloroprene rubber (CR) Known for its well-rounded performance, it offers oil resistance, ozone resistance, and aging resistance.
EPDM Rubber (EPDM) Excels in high-temperature resistance (-50~150ºC) and boasts strong weather resistance, making it ideal for prolonged outdoor exposure.
Fluorine rubber (FKM) Withstands extreme temperatures (-20~250ºC) and resists chemical corrosion, suitable for the harshest environments.
Silastic (VMQ) Offers high temperature resistance (-70~300ºC) and exceptional transparency, alongside superb electrical performance.
Chlorinated sulfated polyethylene rubber (CSM) Resists strong acids and alkalis like concentrated sulfuric and nitric acid, with excellent permeability resistance.
Conductive rubber Specially designed with conductive fibers or metal mesh to effectively prevent static accumulation.
Fire retardant rubber Enhanced with flame retardants such as aluminum hydroxide, this variant has passed UL 94 flame retardant certification.
2. Structural composition of the rubber pipe
The glue layer Crafted for direct interaction with the conveyed medium, it features wear and corrosion resistance, including 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 categorized into versatile 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. |
