HDPE Electrofusion Coupling Fitting (Size 50mm)

A: The core advantages are focused on three aspects, which are also the key highlights for engineering applications:

• 1.High-Quality & Durable Material: Made of 100% pure HDPE raw materials without any harmful additives, complying with ISO and ASTM standards. It has excellent corrosion resistance and aging resistance, and can be used stably in underground, humid or harsh environments. The service life can reach more than 50 years under reasonable working conditions, reducing long-term maintenance costs.
• 2.Reliable Seamless Connection: The advanced electrofusion technology ensures uniform heating of the built-in resistance wires, realizing molecular-level fusion between the fitting and the pipe. The strength of the joint is not lower than that of the pipe itself, which completely solves the problem of easy leakage, loosening and other defects of traditional connection methods (such as flange connection, thread connection).
• 3.Efficient & Easy Construction: Compatible with universal electrofusion welding machines on the market, and it can also be seamlessly integrated with pipeline systems that use hydraulic hose fittings, an fitting and stainless steel water pipe fittings. No professional senior operators are needed-new operators can master the operation after simple training. It is especially suitable for construction in narrow spaces (such as indoor pipelines, underground trenches), which greatly improves construction efficiency and saves project time. Compared with installation of stainless steel water pipe fittings, it is more convenient, and it can be used together with hydraulic hose fittings and an fitting without additional adaptation parts.

A: The rated pressure of this product is 1.6MPa, which fully meets the requirements of municipal and construction pipeline engineering, and can safely bear the pressure of conventional water supply, gas transmission and other media. It has strong compatibility: it is suitable for 50mm diameter various PE pipes and steel-reinforced PE pipes, and can also be matched with hydraulic hose fittings, an fitting and stainless steel water pipe fittings in mixed pipeline systems. The main application scenarios include:

• Residential indoor and outdoor water supply pipe network connection
• Municipal small-scale water supply and drainage pipeline laying
• Agricultural irrigation pipeline docking and maintenance
• Fire protection pipeline system connection

A: To ensure the stability and leak-proof performance of the joint, please pay attention to the following four key points during construction:

• Material Compatibility: The pipe and the fitting must be the same HDPE material to avoid fusion failure caused by material incompatibility, which will affect the joint strength.
• Pipe Surface Treatment: The insertion area of the pipe should be polished in advance to remove the 0.1-0.3mm oxide layer and surface dirt, and keep it clean and dry. Any oil stain, water stain or oxide layer will lead to false welding and leakage.
• Proper Insertion: The cutting surface of the pipe must be flat and vertical. When inserting, it should be inserted in place according to the marked line on the fitting to ensure sufficient fusion area. Welding must be completed on the same day after assembly to avoid contamination of the insertion area.
