Key Features
- Socket-spigot structure: socket end with built-in rubber ring seals against pipe spigot; spigot end inserts into another fitting's socket.
- Standard 90° turn: suitable for vertical-to-horizontal transitions and corner turns.
- Rubber ring seal: quick installation without solvent cement or curing time, can be installed in wet conditions.
- Corrosion resistant: all-UPVC construction, non-rusting, long service life.
Manufacturing Process
Elbow body manufactured via high-precision injection molding. Socket end has machined groove for rubber ring installation. Spigot end is chamfered per standards for easy insertion.
Critical Process Parameters
- Wall thinning in bend ≤10%.
- 90°±1° angle between centerlines.
- Socket rubber ring groove dimensional accuracy.
- Precise spigot OD and chamfer machining.
Raw Material Characteristics
