4 Standard Connection Methods
Our φ110mm PP pipes support four reliable connection methods to suit different installation requirements:
1. Hot Melt Welding (Recommended for Permanent Connections)
- Best for: Underground installations, high-pressure systems and permanent ductwork
- Process: Heat both pipe ends to 260℃, then press together to form a seamless joint
- Advantages: Joint strength exceeds pipe body strength, 100% leak-proof
- Compatible with: All standard φ110mm PP pipes and fittings
2. Socket Connection (Quick Installation)
- Best for: Above-ground installations, temporary systems and easy disassembly
- Process: Insert pipe into pre-molded socket fitting and secure with solvent cement
- Advantages: Fast installation, no special tools required
- Compatible with: φ110mm socket fittings
3. Flanged Connection (Removable Sections)
- Best for: Equipment connections, sections requiring regular maintenance
- Process: Weld PP flanges to pipe ends, then bolt together with gasket
- Advantages: Easy to disconnect and reassemble
- Compatible with: Fans, scrubbers and other equipment
4. Flexible Hose Connection (Vibration Isolation)
- Best for: Connecting to vibrating equipment, compensating for thermal expansion
- Process: Use PP flexible connectors to join pipe sections
- Advantages: Absorbs vibration and noise, allows for minor misalignment
Step-by-Step Installation Guide for φ110mm PP Pipe
General Installation Requirements
- Support Spacing: Install hangers every 1.5m for horizontal pipes and every 2m for vertical pipes
- Expansion Joints: Add an expansion joint every 20m to accommodate thermal expansion
- Fixed Brackets: Install fixed brackets at both ends of each straight section and at all elbows
- Clearance: Maintain 30mm clearance between hangers and pipe insulation
Hot Melt Welding Procedure
- Cut pipe to length with a fine-tooth saw, ensuring a square cut
- Remove all burrs and sharp edges from the pipe end
- Clean both pipe and fitting surfaces with isopropyl alcohol
- Set welding machine to 260℃ and allow to warm up
- Simultaneously heat pipe and fitting for 15-20 seconds
- Remove from heater and immediately press together firmly
- Hold for 30 seconds until joint cools completely
- Inspect weld bead for uniformity and absence of defects
Hanger Installation Specifications
- Boom distance from cross arm end: 30mm
- Boom distance from pipe outer edge: 30mm
- Add fixed brackets at both ends of all elbows
- Main duct hangers should be at least 200mm away from branch pipes
- Use insulated wooden supports for air conditioning ducts
Typical Application Scenarios for φ110mm PP Pipe
The 110mm diameter is the most versatile size, ideal for:
- Laboratory Fume Hoods: Standard size for connecting individual fume hoods to main ductwork
- Small Industrial Workstations: Local exhaust for etching stations, plating tanks and chemical benches
- Pharmaceutical Clean Rooms: Ventilation for production areas and laboratory spaces
- Chemical Storage Rooms: Exhaust systems for storing acids, alkalis and solvents
- Wastewater Treatment Plants: Ventilation for pump rooms and chemical dosing areas
- Educational Institutions: School and university laboratory ventilation systems

Frequently Asked Questions (FAQ)
Q: What is the difference between SN4 and SN8 wall thickness?
A: SN4 (4.2mm) is the standard thickness suitable for most general ventilation applications. SN8 (6.3mm) is heavy-duty thickness recommended for high-pressure systems, outdoor installations and applications requiring extra mechanical strength.
Q: Can I connect φ110mm PP pipe to other sizes?
A: Yes, we offer PP pipe reducers that allow you to connect φ110mm pipe to other standard sizes including φ75mm, φ90mm, φ160mm and φ200mm.
Q: What is the maximum airflow for φ110mm PP pipe?
A: The recommended maximum airflow is 2,000 m³/h at a velocity of 20 m/s. For systems carrying abrasive particles, we recommend a maximum velocity of 15 m/s.
Q: Can φ110mm PP pipe be used outdoors?
A: Yes, our standard PP pipes are UV-stabilized and can be used outdoors. For prolonged exposure to direct sunlight in harsh climates, we recommend our special UV-resistant PP grade.
Q: How do I cut φ110mm PP pipe?
A: You can cut PP pipe with a fine-tooth saw, pipe cutter or reciprocating saw. Always ensure a clean, square cut for proper connection.
Q: What is the minimum order quantity for φ110mm PP pipe?
A: We accept orders as small as 1 piece for standard sizes. Bulk discounts are available for orders of 100 meters or more.
