The Industrial UPVC Pipe Socket (Straight Coupling) is engineered for joining two straight runs of industrial UPVC pipe with absolute joint integrity. Built to handle continuous working pressures and aggressive chemical media, this high-performance socket creates a permanent, monolithic bridge using standard industrial solvent welding techniques.
Technical & Design Advantages:
Deep-Socket Bonding Depth: Engineered with full-depth socket insertion zones that maximize solvent cement contact area for high longitudinal pull-out resistance.
High Hydrostatic Strength: Thick-walled industrial design ensures high safety margins against unexpected line pressure surges and thermal stress.
Non-Toxic & Chemically Pure: Formulated without heavy-metal stabilizers, ensuring chemical purity and preventing fluid contamination during chemical transfer.
Seamless Alignment Center Stop: Features a molded internal center stop ring that ensures exact pipe alignment and balanced insertion depth during field assembly.
