HDPE Fabricated Fittings are large-diameter or non-standard pipe connection components manufactured by cutting, processing, and hot-melt welding HDPE pipes. These fittings are primarily used for large-size or complex-structured piping systems that cannot be produced through injection molding.
Puhui Industry specializes in manufacturing PE100 grade HDPE welded pipe fittings, widely used in municipal water supply, drainage projects, mining transportation, industrial fluids, and large-scale infrastructure projects.
Compared to standard Butt Fusion Fittings and Electrofusion Fittings, welded fittings offer greater structural flexibility and customization capabilities, meeting the needs of complex engineering and large-diameter piping systems.
1. Fabricated Elbow: Used for changing direction in large-diameter piping systems, welded elbows can be customized to different angles according to project requirements.
Product Features:
Customizable angles (30° / 45° / 60° / 90°)
Suitable for large-diameter pipes
Stable structure, high strength
2. Fabricated Tee: Used for branch connections between main pipes and branch pipes.
Product Types:
Equal diameter tee
Reducing tee
Product Features:
High pressure resistance
Suitable for complex piping systems
Customizable sizes and structures
3. Fabricated Reducer: Used for connecting pipes of different diameters to achieve flow and pressure transitions.
4. Fabricated Flange: Used for connecting HDPE pipes to valves, equipment, or metal pipes.
5. Fabricated Cross: Used for multi-directional piping systems, suitable for large-scale engineering networks.
6. Large Diameter Special Fittings: Used for ultra-large diameter and non-standard engineering projects, such as large municipal and industrial systems.
Large Diameter Engineering Capability:
Supports DN400mm–DN2000mm and larger sizes, meeting the needs of large-scale municipal and industrial projects.
High-Strength Welded Structure:
Utilizes multi-segment HDPE hot-melt welding technology, resulting in a stable structure and strong pressure resistance.
High Customization Capability:
Angles, dimensions, and structures can be customized according to engineering drawings to meet complex design requirements.
Leak-Free Integrated Connection:
The welded structure forms a unified structure, effectively reducing the risk of leakage and improving system safety.
Cost Optimization Solution:
Compared to injection-molded large pipe fittings, no mold development is required, making it suitable for engineering projects and mass customization.

Puhui Industry - Professional HDPE Welded Pipe Fittings Manufacturer
Q1: What are HDPE Fabricated Fittings?
A: HDPE Fabricated Fittings are large-diameter or non-standard pipe fittings manufactured by cutting and welding HDPE pipes.
Q2: What is the difference between welded pipe fittings and injection-molded pipe fittings?
A: Welded pipe fittings are suitable for large-diameter and non-standard structures, offering greater flexibility; injection-molded pipe fittings are suitable for mass production of standard sizes.
Q3: What is the maximum size that can be produced?
A: We can typically produce large-diameter pipe fittings from DN200mm to DN2000mm and above, depending on project requirements.
Q4: Are welded pipe fittings suitable for high-pressure systems?
A: Yes, they can be designed according to SDR11 or SDR17 and are suitable for medium and high-pressure engineering systems.
Q5: Do you support customization based on drawings?
A: Yes, we can design and produce according to customer engineering drawings.
Q6: What is the service life of welded pipe fittings?
A: Made of PE100 material, the service life under normal operating conditions can reach over 50 years.
