90 Degree PPR Elbow

    90 degree PPR elbow, also known as right angle elbow or ppr pipe fittings elbow, is a fitting used in plumbing systems to connect two ppr pipes with the same or different nominal diameters, making the ppr pipe turn 90 degrees. It is mainly used in plumbing installations to change the direction of the pipeline at the corner, ensuring the rationality of energy transportation and construction planning.

Comparison between PPR 90 degree elbow and HDPE 90 degree elbow

Materials and characteristics

A) PPR 90 degree elbow: PPR (Polypropylene Random Copolymer) is a thermoplastic resin material that is odorless, non-toxic, high-temperature resistant, pressure resistant, and corrosion-resistant. PPR pipe and fittings are commonly used in hot water systems because they can withstand higher temperatures without degradation. PPR pipe also have good insulation performance and a long service life.
B) HDPE 90 degree elbow: HDPE (High Density Polyethylene) is a high-density polyethylene material with good chemical resistance, wear resistance, impact resistance, and low temperature resistance. HDPE pipe and fittings are commonly used in cold water systems because they have good corrosion resistance and lower costs. HDPE pipe suitable for transporting drinking water.
application area 
A) PPR 90 degree elbows: Due to the high temperature resistance of PPR pipe, they are commonly used in hot water supply systems for homes and commercial buildings, including water heaters, boilers, and central heating systems.
B) HDPE 90 degree elbow: HDPE pipe used in municipal water supply, irrigation, rainwater discharge, wastewater treatment, and industrial fluid transportation due to their corrosion resistance and cost-effectiveness.

Matters needing attention
1. When selecting a PPR 90 degree elbow, it should be ensured that it complies with relevant standards and specifications to ensure installation quality and safe use.
2. During the installation process, attention should be paid to operating standards to ensure the quality and reliability of hot melt connections.
3. During use, it is necessary to regularly check whether there is any leakage, corrosion or other phenomena at the elbow connection. If there are any abnormalities, they should be dealt with in a timely manner.
