What is Elbow 50mm 45* RAKtherm PPRc ?

 

Elbow 50mm 45° RAKtherm PPRc PN 25 is a 45-degree elbow fitting for Polypropylene Random Copolymer (PPR/PPRc) piping systems. It connects two 50mm PPR pipes at a 45° angle, allowing smooth directional changes in plumbing or HVAC lines while minimizing flow resistance compared to a 90° elbow.

RAKtherm, manufactured in Ras Al Khaimah (UAE), produces high-quality PPRc systems for hot and cold water distribution.

Description

• Type: 45° Elbow (socket fusion type, equal diameter).
• Design: Monolithic PPR body with socket ends for heat-fusion welding. The smooth internal bore reduces turbulence and pressure drop. It is part of RAKtherm’s comprehensive range of PPR fittings, which includes 90° elbows, tees, reducers, and more.
• Key Features:
  • Excellent corrosion, scale, and chemical resistance.
  • Hygienic, non-toxic, and food-grade material suitable for potable water.
  • High durability with low thermal conductivity (helps maintain water temperature).
  • Lightweight yet strong, with a homogeneous welded joint that is stronger than the pipe itself.
  • UV-resistant variants available for exposed installations.

Specifications (Typical for RAKtherm PPRc PN 25)

• Size: 50mm (outer diameter, equal sockets).
• Angle: 45°.
• Pressure Rating: PN 25 (nominal pressure up to 25 bar at 20°C; derates with temperature, suitable for hot water systems).
• Material: High-quality Polypropylene Random Copolymer (PP-R Type 3), compliant with DIN 8077/8078 standards.
• Temperature Range: Continuous operation from 0°C to 90°C, with short-term peaks up to 100°C. Designed for a service life of approximately 50 years under normal conditions.
• Pipe Compatibility: Matches RAKtherm PN 25 50mm pipes (wall thickness around 10.1mm for Series 2 PN25, ID ~29.8mm).
• Color: Typically green (standard for PPRc); white or grey options may exist.
• Weight/Dimensions: Refer to the official catalogue for precise values (generally lightweight, e.g., a few hundred grams per fitting). Packing quantities vary (often in boxes for contractors).

These fittings are widely used in UAE-exported systems and available through regional distributors.

Usage

• Primary Applications:
  • Hot and cold potable water supply lines.
  • HVAC systems (chilled water, heating, and air-conditioning networks).
  • Underfloor heating and central heating.
  • Industrial and commercial fluid transport where gentle bends are needed to optimize flow and reduce pressure loss.
• Ideal for routing pipes around obstacles, changing direction in branched networks, or in tight spaces where a sharper 90° turn would cause excessive turbulence or require more space.

Installation

RAKtherm PPR systems primarily use socket heat fusion welding for permanent, leak-proof joints. No glue, threads, or mechanical seals are needed for the PPR-to-PPR connection.

General Steps (Always follow manufacturer’s detailed instructions and use trained personnel):

1. Preparation: Cut the 50mm PPR pipe squarely using a dedicated pipe cutter. Deburr and clean the pipe end and fitting socket thoroughly (dry cloth; no grease or dirt).
2. Heating: Preheat the fusion welding machine to ~260°C. Simultaneously heat the pipe end (on the male mandrel) and the elbow socket (on the female bush) for the recommended time (for 50mm, typically 15–20+ seconds — check exact timing in RAKtherm manual as it depends on size and tool).
3. Joining: Remove from the tool quickly, align the pipe and fitting straight (no twisting), and push the pipe fully into the socket until it bottoms out. Hold firmly in place for 20–30 seconds or until cooled enough to handle.
4. Cooling: Allow the joint to cool naturally before applying pressure or stress. Full system pressure testing should occur only after complete cooling.
5. Support: Use RAKtherm pipe clamps or brackets for proper support and to accommodate thermal expansion.
6. Safety: Work in a well-ventilated area; wear appropriate PPE. Avoid water or moisture during welding.

Key Tips:

• Use genuine RAKtherm welding equipment for best results.
• Do not weld in extreme cold or heat without adjustments.
• Test the entire system hydrostatically after installation.
• For detailed welding parameters, socket depths, and times, consult the official RAKtherm catalogue or installation manual (available on raktherm.com).
