1.8mm ID Polyurethane Air Hose outer diameter (OD) specification
The outer diameter of PU trachea with 8mm ID is usually 12mm, and the wall thickness is about 2mm (calculation method: outer diameter 12mm - inner diameter 8mm=wall thickness 4mm, with 2mm wall thickness on both sides)
The main application scenarios of 2.8mm ID Polyurethane Air Hose
1. Industrial automation and pneumatic systems
Compressed air delivery: used for gas supply pipelines of cylinders, solenoid valves, and pneumatic tools (such as screwdrivers and grinders), with a pressure resistance range of usually 10-12 bar.
Equipment connection: Transmit power in robotic arms, packaging machines, and textile machinery due to its good flexibility (minimum bending radius of 20-30mm) and resistance to twisting.
2). Transportation and Energy
Pneumatic braking systems for rail transit vehicles and door control devices for buses.
The compressed air control system of the hydropower station is weather resistant and suitable for outdoor environments.
3. Precautions for use
1) The ambient temperature should be controlled between -20 ° C and+40 ° C. Both high and low temperatures can affect the performance of the trachea.
2) The working pressure is ≤ 1.2 MPa (approximately 12 kgf/cm ²), and the blasting pressure is generally three times the working pressure
When the temperature rises, the pressure resistance decreases (e.g. the pressure resistance drops to about 0.5 MPa at 60 ° C)
3) Strong acids, strong bases, and polar solvents (such as acetone) are prohibited from causing swelling or cracking of pipes.
4) Avoid environments with chemical gases such as ozone, which may cause cracks.
5) Moist storage can easily cause hydrolysis aging, and the recommended storage period is ≤ 2 years.
6) Bending radius: ≥ 20mm (dynamic application requires ≥ 30mm), excessive bending can easily lead to fatigue fracture.
7) The incision should be flat and vertical. When inserting the joint, ensure it is at the bottom and conduct a tensile test to prevent detachment. Avoid external pulling or contact with sharp objects to prevent scratching the outer wall.
