PU Tube OD 10 mm ID 6.5 mm

Yantai Zhengyuan Polyurethane Co., Ltd. was established in 2007 and has been committed to the research and development, production, and sales of polyurethane products since its inception. Our company is located in Yantai, Shandong, the birthplace of polyurethane products in China, and we have unique advantages in technical support. China's large raw material manufacturer Wanhua is also located here, which can save a lot of transportation costs in raw material procurement. After years of development, we have established a branch factory in Linyi, Shandong (a logistics hub) to facilitate the transportation of products to various parts of the country. Our products are sold to more than 20 countries and regions including Brazil, Germany, Italy, Spain, Nigeria, Russia, India, Thailand, Vietnam, etc. The PU Tube OD 10mm ID 6.5mm produced has received unanimous praise from customers for its high-quality and reasonable price. Welcome to visit the factory anytime.
1. PU Tube OD 10mm ID 6.5mm wall thickness
Wall thickness=(outer diameter - inner diameter)/2=(10 mm -6.5 mm)/2=1.75 mm
So, the nominal wall thickness of this PU hose is usually 1.75 millimeters.
2. What is the general pressure resistance of PU Tube OD 10 mm ID 6.5 mm?
PU (polyurethane) gas pipes are known for their high toughness, wear resistance, and bending resistance, but their rated working pressure is usually lower than that of nylon pipes or some high-pressure rubber pipes.
Typical working pressure range: For PU pipes with a wall thickness of 1.75mm, the conventional safe working pressure is generally around 0.8 MPa to 1.0 MPa (approximately 8-10 kg force/cm2).
Blasting pressure: It can usually reach about 3 times the working pressure, which is about 2.4 MPa to 3.0 MPa.
3. What should be noted during use?
To ensure safety, reliability, and extend service life, please pay attention to the following points:
1) Pressure and temperature:
Strictly prohibit overpressure use: Do not exceed the maximum working pressure specified by the manufacturer, and it is recommended to leave a safety margin.
Pay attention to temperature effects: The pressure resistance of PU pipes will vary with temperature. When the temperature rises, its pressure bearing capacity and service life will decrease. The working temperature range of standard PU pipes is usually -20 ° C to+40 ° C. Avoid using them at temperatures that are too high or too low.
2) Media compatibility:
PU pipes have excellent oil and chemical resistance, but are not resistant to strong acids, strong bases, and certain organic solvents such as ketones and esters.
The conveying medium must be compatible with the pipe material. Before transporting special gases or liquids, please confirm their chemical compatibility.
3) Installation and use:
Bending radius: Although PU tubing has good flexibility, it should be avoided to use it for a long time at the minimum bending radius (usually 4-6 times the outer diameter of the tubing), otherwise it may cause buckling, reduced flow rate, or stress cracking.
Avoid external damage: Keep away from sharp objects, friction points, or overheated surfaces (such as engine exhaust pipes). Protective covers or cable trays can be used.
Correct connection: Use PU pipe specific quick plug connectors or clamp type connectors that match the size to ensure a secure connection and reliable sealing. The insertion depth should be sufficient.
4) Inspection and maintenance:
Regularly inspect the pipeline for wear, cuts, aging (hardening, cracking), permanent deformation, or joint leaks.
If any damage is found, it should be replaced immediately and no attempt should be made to repair it.
