Rubber tubing, a versatile and essential component in many industries, is crafted primarily from robust rubber. This tubular product features an inner and outer rubber layer, complemented by a reinforcing skeleton layer, effectively transporting gases, liquids, slurries, or granular materials. Its core function lies in its ability to facilitate media transmission through its remarkable elastic sealing and pressure-bearing capabilities. Widely recognized for its adaptability, rubber tubing is employed across diverse sectors, including industrial, automotive, and medical fields, showcasing its indispensable role in modern technology.
1. Comprehensive Introduction to Rubber Pipe Materials
Crude Rubber: Boasting high elasticity, excellent wear resistance, and the ability to withstand bending and scratching, crude rubber is ideal for use in low-pressure environments.
Protobutadiene Rubber (SBR): Known for its remarkable wear resistance and cost-effectiveness, though it offers limited oil resistance. It is a popular choice where cost is a primary consideration.
Cis-Polybutadiene (BR): Offers superb moisture resistance and outstanding low-temperature resilience, maintaining elasticity even at -50ºC, making it ideal for cold environments.
Nitrile Rubber (NBR): Known for its exceptional resistance to oils, including mineral and lubricating oils, though it has weaker ozone and high-temperature resistance.
Chloroprene Rubber (CR): Offers a balanced profile of oil resistance, ozone protection, and aging resistance, making it a well-rounded option for diverse applications.
EPDM Rubber (EPDM): Withstands high temperatures ranging from -50 to 150ºC and offers robust weather resistance, perfect for prolonged outdoor exposure.
Fluorine Rubber (FKM): Exceptionally resistant to high temperatures (-20~250ºC) and chemical corrosion, making it suitable for extreme environmental conditions.
Silastic (VMQ): Provides impressive high-temperature resistance (-70~300ºC), along with high transparency and excellent electrical performance, ideal for advanced applications.
Chlorinated Sulfated Polyethylene Rubber (CSM): Excels in resisting strong acids and alkalis, including concentrated sulfuric and nitric acids, with superior permeability resistance.
Conductive Rubber: Embedded with conductive fibers or metal mesh, this rubber type effectively prevents static accumulation, ensuring safety in sensitive applications.
Fire Retardant Rubber: Enhanced with flame retardants such as aluminum hydroxide, this rubber has passed the rigorous UL 94 flame retardant certification, ensuring safety.
2. Structural Composition of the Rubber Pipe
The Glue Layer: This layer directly contacts the conveying medium, designed with wear and corrosion resistance properties, including resistance to oil, acid, and alkali.

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. Structural Types of Rubber Pipes: Includes sandwich hoses, braided hoses, winding hoses, and full hoses, each tailored to specific application needs.
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. Vast Application Areas: Explore the extensive range of applications across industries and sectors.
| 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 Assurance: Commitment to quality and security through adherence to stringent standards.
| 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. |
