PPR Fittings Complete System

1. Connecting Aaccesorios

Tipo	Angle Specifications	Aplicacións
ELBOW	45 °/ 90 ° /180 °	Reroute
EQUAL COUPLING		Equal diameter pipes are connected in straight lines
REDUCING COUPLING	Reducing range ±50%	Different pipe diameters are connected
UNION	Detachable design	Equipment access interface

2. Branch Aaccesorios

• Tee: Equal diameter/reducing diameter, T /Y shunt
• Catro-way Cruz: Cross pipe connection
• Multi-Cruz: Integrated distribution system

3. Control Aaccesorios

• Válvula de bola: DN15-DN100 full flow control
• Válvula de globo: precise flow control
• Temperatura control valve: automatically adjust the medium temperature

4. Special Function Aaccesorios

Types of accessories	Core technology	Functional features
Filter Valve	100 mesh stainless steel strainer	Intercepting pipe impurities
Pressure reducing valve	Diaphragm type pressure regulator	Stabilizing system pressure ±0.05MPa
Silencer tube fitting	Spiral diversion design	Noise reduction 15-20 dB

The complete PPR product family can be grouped into three main categories: pressure-rated pipes, functional pipes, e system fittings (which include connection, branch, control, and special function fittings). Combined, these components provide a comprehensive piping solution for any project — from residential plumbing to industrial systems.

Installation Best Practices — Step-by-Step Checklist

Proper installation is the key to ensuring PPR system performance and longevity. Follow these steps:

Paso	Action	Key Requirement
1. Pipe Cutting	Cut pipe squarely with a pipe cutter	Ensure clean, corte sen rebabas
2. Surface Cleaning	Clean pipe end and fitting socket	Remove dirt, aceite, e humidade
3. Depth Marking	Mark insertion depth on pipe	Match socket depth of fitting
4. Heating	Heat pipe and fitting simultaneously at 260±5°C	Use correct heating time (see formula below)
5. Joining	Insert pipe into fitting with a straight push	No twisting during insertion
6. Cooling	Hold joint in position until fully cooled	Summer: 15 min, Winter: 30 min
7. Visual Inspection	Check for uniform melt ring around joint	Indicates proper fusion

Heating Time Formula: Diámetro de tubo (mm) ÷ 10 × 1.2 segundos

Quick Selection Guide — Choose the Right PPR Pipe for Your Project

Use this table to quickly identify the correct PPR pipe series for different applications:

Application Scenario	Recommended Series	Espesor da parede	Clasificación de presión	Consideración clave
Cold Water Supply	S5 (PN10)	2.0–3.5 mm	1.0 MPa	≤40°C, residential or light commercial
Quente Abastecemento de auga	S3.2 (PN20)	2.8–5.4 mm	2.0 MPa	70–95°C, continuous hot water
Floor Heating System	S3.2 (PN20)	2.8–5.4 mm	2.0 MPa	Use oxygen barrier pipe for heating
High-Rise Main Riser	S2.5 (PN25)	3.5–6.5 mm	2.5 MPa	High pressure requirements in tall buildings
Tubería industrial	S2.5 (PN25)	3.5–6.5 mm	2.5 MPa	High temperature + alta presión
Healthcare / Food Facility	Antibacterial Pipe	Varies by series	Varies by series	>99% taxa antibacteriana, hygiene priority

Pro Tip: For systems with fluctuating pressure, choose one series higher than the calculated requirement. Por exemplo, if your system operates at 1.2 MPa, select PN16 or PN20 rather than PN10 to ensure adequate safety margin.
