Core Structure & Functions
Socket-Spigot Design One or both ends are expanded into sockets with inner diameter slightly larger than pipe outer diameter. Pipes can be inserted directly. It ensures precise alignment and larger bonding area for firm, leak-proof joints.
Straight Pipe Connection Designed for inline extension and connection of equal-diameter PVC pipes, maintaining good pipe straightness.
Simplified Installation Built-in sockets eliminate additional coupling pieces. It saves fitting cost and installation time for long-distance pipeline projects.
Material & Performance Advantages
· Food-grade Virgin PVC-U Resin:
Lightweight, high strength, corrosion-resistant, anti-aging, non-toxic and hygienic.
· Smooth Inner Wall:
Uniform smooth bore creates low flow resistance, resisting scale buildup and blockages for smooth drainage.
· Leak-tight Sealing:
Forms integrated sealed joints with special PVC solvent cement. Some models are equipped with pure rubber gaskets for enhanced sealing and ageing resistance.
Common Types & Specifications
By Nominal Diameter:
Covers mainstream drainage & water-supply sizes: D50, D75, D110, D160, D200 (D = nominal outer diameter in mm).
By End Type:
· Single-socket coupling: One socket end + one plain end, for pipe-to-fitting connection.
· Socket with shoulder: Socket end with raised shoulder, provides superior sealing for high leak-prevention-demand applications.
