45° Elbow

Product Overview

Sikerui PPH 45° Elbow is a high-performance pipe fitting engineered from unplasticized polyvinyl chloride (PPH), designed to provide precise 45-degree directional changes in piping systems. Renowned for its exceptional durability, chemical resistance, and leak-proof performance, this elbow ensures efficient flow redirection while minimizing pressure loss. It complies with international standards such as ISO 4422, DIN 8063, and GB/T 10002.2-2003, making it suitable for demanding applications in plumbing, industrial transport, irrigation, and chemical handling. With a service life exceeding 50 years, it offers a sustainable alternative to metal fittings by combining lightweight design with robust performance .

Features of PPH 45° Elbow

Precise 45-Degree Angle Optimization
- Engineered to redirect fluid flow with minimal turbulence, reducing pressure drop and maintaining consistent flow efficiency in water supply, irrigation, and industrial pipelines .
Superior Corrosion and Chemical Resistance
- Highly resistant to acids, alkalis, salts, and corrosive chemicals, ensuring longevity in aggressive environments like chemical processing plants, mining drainage, and wastewater systems .
Smooth Interior Surface
- The seamless inner wall minimizes friction loss, prevents sediment buildup, and optimizes flow capacity, reducing energy consumption in pumping systems .
Lightweight and Easy Installation
- Up to 50% lighter than metal elbows, enabling faster solvent cement or threaded installations without specialized tools. This cuts transportation and labor costs significantly .
Durable Under Pressure and Temperature
- Rated for pressures up to PN16 (1.6 MPa) and temperatures ranging from -10°C to 60°C (SCH40/SCH80 variants withstand up to 75°C), ensuring reliability in diverse operational conditions .
Eco-Friendly and Safe
- Non-toxic, UV-resistant, and compliant with drinking water standards (e.g., ACS, ISO 4422), making it suitable for potable water systems. The material is recyclable and free from heavy metal additives .

Typical Applications of PPH 45° Elbow

Water Supply Systems: Used in municipal and residential potable water networks for directional changes, ensuring no impact on water taste or quality due to non-corrosive properties .
Industrial Pipelines: Ideal for chemical transport, wastewater treatment, and food processing plants, where resistance to corrosive fluids and ease of maintenance are critical .
Agricultural Irrigation: Facilitates efficient flow redirection in sprinkler and drip irrigation systems, withstanding fertilizers and pesticides without degradation .
Mining and Drainage: Effective in venting corrosive gases and draining acidic liquids in mines, thanks to high chemical resistance and durability .
Electrical Conduits: Serves as a non-conductive, protective elbow for cable management in electrical and telecommunications installations .
