While PVC threaded penetration pipes do not completely surpass metal sleeves in fire resistance, their self-extinguishing properties after flame-retardant modification, excellent synergy with fire-stopping materials, and the low-smoke and low-toxicity cha
As water freezes, its volume expands, exerting enormous pressure on the inner wall of the pipe. Maintaining a slight movement of the water flow can utilize the characteristics of flowing water to reduce the risk of freezing.
As a new type of composite pipe, the core performance of PPR tube with fiber depends on the bonding strength of the interface between fiber and matrix.
Vibration aging treatment can stimulate plastic deformation in the micro-regions inside the material and further reduce residual stress.
Not all PPR tube with fiber interface processing methods are exactly the same, and it needs to be judged in combination with the specific structure of the pipe.
In the hidden vein of modern building safety, CPVC fire protection fittings, with their clever "plastic over fire" approach, quietly build an invisible line of defense against intense flames and high temperatures.
