Pressure Resistance Failure of PEEK Oil and Gas Pipe Fittings

The quality defense line of PEEK pressure-bearing parts lies in non-destructive testing; qualified appearance does not mean qualified interior; pores and weld lines are the two major roots of pressure-bearing failure.; After confirming effectiveness, solidify the parameters and practices into the...

Low-Temperature Brittle Cracking of PE Products

PE low-temperature brittle cracking = double insurance of 'grade + structure': HDPE in particular requires vigilance against low-temperature notch sensitivity; passing at room temperature does not mean passing at low temperature — verification must simulate the real use temperature.

PE Film Poor Heat Sealing

For PE heat sealing, first determine the temperature window according to the grade melting point, then check the film surface condition and heat seal layer thickness; slip agent is a double-edged sword, requiring both opening and sealing performance, and the dosage must be weighed.
