Ruisongbuild High-Pressure PPR 90 Degree Bend PN20 PN25 ISO Certified

Description

Ruisongbuild PPR 90° Elbows: The Cornerstone of Secure Piping Layouts

The 90-degree elbow (also known as a right-angle bend or L-fitting) is the most essential fitting for creating directional changes in any rigid PPR pipeline. At Ruisongbuild, our PPR 90° elbows are manufactured from 100% virgin Random Copolymer Polypropylene, specifically designed to handle the hydraulic stress at critical junction points. By creating a monolithic joint via thermal socket fusion, our fittings ensure the corner is as strong as the pipe itself.

Technical Specifications & Industrial Standards

• Material: 100% Virgin Random Copolymer Polypropylene (PPR).

• Standard Compliance: DIN 8077, DIN 8078, ISO 15874.

• Pressure Ratings: PN25 (SDR6) – Suitable for high-pressure surges.

• Temperature Range: Constant performance up to 95°C (203°F).

• Jointing Method: Socket Heat Fusion (Creates a permanent molecular bond).

• Color Identification: Available in Green, White, Gray, or custom colors.

• Safety Certification: Lead-free, BPA-free, certified for potable water.

Why Ruisongbuild PPR 90° Elbows?

• 100% Leak-Proof Integrity: Thermal fusion eliminates the need for gaskets or threads, creating a single, continuous piece of material that is immune to joint separation.

• Superior Thermal Insulation: Low thermal conductivity minimizes heat loss in hot water lines, making it more energy-efficient than metallic elbows.

• Acoustic Comfort: The smooth internal bore and elastic material properties dampen the noise of flowing water, providing a quieter environment in residential buildings.

• Total Corrosion Resistance: Unlike copper or galvanized bends, our PPR elbows will never rust, pit, or experience galvanic corrosion, even in aggressive water conditions.

Global Applications

• Residential Plumbing: Hot and cold water house connections.

• Commercial Infrastructure: High-rise water risers and distribution networks.

• Central Heating & HVAC: Radiator connections and chilled water loops.

• Industrial Fluids: Transporting compressed air and non-corrosive industrial liquids.

Frequently Asked Questions

Q1: What is the benefit of a socket fusion joint over a threaded joint?
A: Socket fusion creates a homogeneous molecular bond between the fitting and the pipe, effectively turning them into one single piece. Threaded joints rely on mechanical friction and seals, which can degrade and leak over time due to thermal expansion.

Q2: Can I use Ruisongbuild PPR 90° elbows for drinking water?
A: Yes. Our fittings are made from food-grade, non-toxic resins. They do not leach chemicals or metals into the water, ensuring it remains safe, odorless, and tasteless for potable use.

Q3: What temperature should the PPR welding machine be?
A: The standard temperature for PPR heat fusion is 260°C (500°F). Both the pipe end and the elbow socket must be heated for the specified number of seconds before joining.

Q4: How long will a PPR 90° elbow last?
A: When operated within its rated pressure and temperature (up to 70°C for most applications), our PPR fittings have a design life of over 50 years.

Q5: Are these elbows compatible with standard PPR pipes?
A: Yes. Our elbows follow the metric DIN 8077/8078 standard, making them fully compatible with any standard PPR pipe of the same nominal diameter (e.g., 20mm, 25mm, 32mm).
