75mm PPR Electrofusion Flange Fitting

A: There are three core advantages: ① More reliable connection: Electrofusion welding with embedded heating wires ensures full melting of PPR material, forming a gap-free integrated joint-far more stable than traditional flange, hydraulic hose fittings and some stainless steel pipe fittings. It greatly improves fusion tensile strength, avoids leakage, and is suitable for high-pressure fluid transportation. ② Higher efficiency: No complicated bolt fastening (unlike traditional flange and partial stainless steel pipe fittings); welding is completed quickly with a special electrofusion welding machine, saving time and labor costs, more efficient than hydraulic hose fittings installation. ③ Stronger adaptability: Precisely matching 75mm PPR pipes, it can be perfectly paired with hydraulic hose fittings and stainless steel pipe fittings in various projects. PPR's acid-alkali resistance and anti-aging performance enable long-term use in cold/hot water and mild corrosive fluid transportation, with lightweight design for easy handling and installation (more convenient than stainless steel pipe fittings and traditional flange).

A: The high-quality PPR material has three key features, with obvious advantages over stainless steel pipe fittings and hydraulic hose fittings materials: ① Excellent thermoplasticity: It melts quickly under electrofusion welding high temperature and solidifies rapidly, forming a firm bond. No harmful gases are released, meeting drinking water transportation standards-better than some non-environmentally friendly materials in hydraulic hose fittings and traditional flange. ② Stable physical and chemical properties: Withstanding up to 95℃ high temperature and -20℃ low temperature (more durable than some stainless steel pipe fittings in low-temperature environments), it is corrosion-resistant and non-scaling, avoiding pipeline blockage and extending service life-superior to traditional flange and common hydraulic hose fittings. ③ Light weight: Its density is only 1/8 of metal fittings (including stainless steel pipe fittings), reducing handling and construction difficulty, and its non-conductive, non-thermal conductive features ensure safer use than metal-based flange and hydraulic hose fittings.

A: The 75mm specification refers to the nominal outer diameter of the fitting, perfectly matching 75mm PPR pipes. It can also be used with hydraulic hose fittings, stainless steel pipe fittings and traditional flange in mixed pipeline systems. As a medium and large-sized fitting, it is suitable for scenarios requiring certain flow: high-rise residential water supply/drainage main pipes (matching stainless steel pipe fittings for auxiliary connection), villa whole-house pipelines, small chemical and electroplating plant mild corrosive fluid transportation (cooperating with hydraulic hose fittings for flexible connection), campus/hospital/mall central water supply and heating (replacing traditional flange for higher efficiency), and agricultural irrigation main pipelines. It adapts to complex outdoor environments, with longer service life than ordinary hydraulic hose fittings and partial stainless steel pipe fittings.
