TPU Tubing Application
Problem Phenomenon
TPU pneumatic tubing is oil-resistant and wear-resistant, but softens in high-temperature environments, and hydraulic tubing fails under pulsation
Cause Analysis
TPU tubing is oil-resistant and wear-resistant, suitable for pneumatics and hydraulics; but high-temperature softening limits application; pulsating working conditions require high-elasticity grades; too small a bending radius produces stress concentration; when troubleshooting on site, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience
Solution
①Select tubing grade according to temperature and pressure; ②Select high-elasticity grades for pulsating conditions; ③Design bending radius according to specifications; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
TPU tubing selection is a three-dimensional check of temperature, pressure and pulsation; bending radius is an installation red line; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
