THE basic function of pneumatic hose is to convey pressurized air to actuators, valves, tools and other devices. But there are countless types and sizes of pipes and hoses on the market, so engineers should consider many important factors in order to choose the right pneumatic pipes and pneumatic hoses for a given task.
Thermoplastic hose is made of several common materials. But manufacturers offer countless polymer formulations to meet specific needs. Typical materials used in pneumatic applications include: Polyurethane tubing is strong, flexible, kink and abrasion resistant, and it withstands contact with fuels and oils, and can be in contact with fuel and oil. It is commonly used in pneumatic execution and logic systems, robotics and vacuum equipment, as well as various semiconductor manufacturing, medical and laboratory applications.
Nylon hose is tough, light and dimensionally stable. It can be formulated for higher-pressure pneumatics, flexibility for routing in tight spaces, high flexural-fatigue resistance and low water absorption.
Polyethylene hose is often used in low pressure pneumatic and pneumatic control. It has good chemical resistance and solvent resistance, good flexibility and relatively low cost.
Finally, hose and tubing sometimes must meet regulations or standards from agencies like FDA, DoT, UL and ISO. When questions arise regarding product compliance, experts always recommend seeking advice from application engineers from reputable manufacturers.
