Application Scenarios

Applications 

Indoor Sanitary Routing for Buildings 
Perfect for navigating the complex architecture of modern buildings. These fittings are the crucial linking components for indoor drainage networks, safely routing wastewater from sinks, toilets, and laundry rooms through the walls and floors of apartments and commercial offices.
 
Urban Stormwater & Rainwater Junctions 
Build a resilient defense against flooding. Our durable fittings are essential for municipal engineering, seamlessly connecting the vast network of underground rainwater drainage pipes that safely channel heavy storm runoff away from city streets and public infrastructure.
 
Harsh Sewage & Effluent Transport Networks 
Rely on connections that will not fail under pressure or chemical exposure. These PVC joints are heavily utilized in industrial and agricultural sectors to securely route highly polluted sewage and wastewater to treatment plants without the risk of toxic leaks.
 
Complete Custom Drainage Frameworks 
No matter the complexity of the layout, these fittings bring the system together. Available in a variety of shapes, they provide the flexibility needed to construct comprehensive, custom-tailored drainage pipeline systems for any landscape or architectural design.

Core Products

Common Connection Methods for PVC Pipes & Fittings

1. Solvent Welding (Solvent Cement Joint) 
Main application: UPVC drain pipe, UPVC pressure water supply pipe
Main application: Large-diameter sewer PVC-U pipe, buried drainage pipeline
 
3. Flange Connection 
Main application: Pump connection, valve joint, industrial PVC pipeline
 
4. Threaded Connection,avoid high-pressure service
Note: Not preferred for pure PVC pipe; mostly for transition to metal components
 
5. Push-Fit / Expanded Socket Joint 
Main application: Agricultural irrigation, low-pressure non-buried pipelines
 
6. Hot-Air Welding 
Use hot-air welding gun with PVC welding rod. 
Important Note: PVC-U rigid pipes shall NOT adopt PPR hot-melt fusion welding. It will lead to material carbonization, crack and leakage risk.
