PPR Electrofusion 90 Degree Elbow

The DN160 PPR Electrofusion 90° Elbow, made from Borealis RA140E/PPB4228 raw material, is rated for a pressure of 20 kg/cm². This gray fitting is designed for 90-degree directional changes in hot water piping systems. Its streamlined internal geometry ensures smooth water flow, minimizing hydraulic losses and preventing the formation of harmful vortices. With a height of 261 mm, a socket depth of 88 mm, and a fusion zone width of 47 mm, its reinforced construction guarantees resistance to softening or deformation under maximum operating temperatures. This PPR Electrofusion 90° Elbow plays a critical role in connecting vertical risers to horizontal pipes and facilitating right-angle turns within building internal hot water systems. The electrofusion joint provides a sealed connection with a service life and strength comparable to the pipe itself.

Compared to standard PPR butt fusion fittings, PPR electrofusion fittings offer several key advantages. Standard butt fusion requires relatively long heating times and specific operator skill for proper alignment. In contrast, PPR Electrofusion 90° Elbow fittings do not require manual control over alignment time or distance. They use an integrated heating coil to generate heat automatically, ensuring consistent weld time and more reliable joint quality. The electrofusion process creates a superior molecular bond at the joint, resulting in higher strength and greater resistance to pull-out and bending compared to standard fused joints. The service life of electrofusion fittings also typically exceeds that of standard butt-fused joints.

Our company is certified under the ISO9001 International Quality Management System. We implement standardized quality control measures across all stages-from incoming inspection and raw material storage to production processes, final inspection, and customer service. This ensures that every product leaving our factory is of high and consistent quality, with uniform dimensions and performance that meet global standards.

When using electrofusion fittings, after scraping the pipe end to remove oxidation and contaminants, apply the special lubricant provided by the electrofusion welder manufacturer. Then, insert the prepared pipe into the fitting socket up to the marked insertion depth, ensuring proper contact. Connect the welder leads to the fitting's terminals, power on the welder, input the correct welding parameters, and initiate the welding cycle. Avoid moving the fitting or pipe during cooling; allow it to cool naturally. The critical points are thorough surface preparation and strict adherence to the specified welding parameters (time, voltage) marked on the fitting. Failure to do so can result in either insufficient or excessive welding, compromising joint performance.
