Can PVC glue stick to PE pipes?

PVC pipes and PE pipes are both common pipes. PVC pipes are often used in drainage, wire protection and other scenarios due to their low cost and high hardness. PE pipes are widely used in water supply and drainage, gas transportation and other fields due to their strong flexibility and corrosion resistance. Many people will have questions during pipeline installation or maintenance: Can PVC glue stick PE pipes? The answer is no. Forcibly using PVC glue to bond PE pipes not only fails to achieve the desired effect, but may also leave safety hazards.

PVC glue, the full name of PVC adhesive, is specially developed for bonding polyvinyl chloride (PVC) materials. Its composition and chemical properties determine that it is only suitable for the connection between PVC pipe fittings. The bonding principle of PVC glue is to dissolve the surface of PVC material, so that the two can merge with each other in the dissolved state, and form a firm connection after the glue solidifies. The material of PE pipe is polyethylene, which has a completely different molecular structure and chemical properties from PVC. The surface of PE pipe is relatively smooth, the molecular chain structure is stable, and PVC glue cannot dissolve or penetrate the surface of PE pipe, so it cannot achieve effective bonding. Even if PVC glue is applied to the surface of PE pipe, the glue only adheres to the surface of the pipe after drying, and cannot form a close bond with the pipe. Under the action of external forces such as pressure and temperature changes, it is easy to fall off, resulting in leakage at the pipeline connection.

In addition, from the perspective of material characteristics, PVC belongs to polar materials, and PE belongs to non-polar materials. The physical properties of the two are significantly different. The compatibility between polar and non-polar materials is poor, which makes it difficult to generate sufficient adhesion between PVC glue and PE pipe. Just like oil and water cannot be naturally fused, PVC glue and PE pipe are also difficult to achieve firm bonding by simply applying glue.

For the connection of PE pipe, the correct way is to use the connection method suitable for PE material, such as hot melt connection or electrofusion connection. Hot melt connection is to use special hot melt equipment to heat the connection part of PE pipe and pipe fitting to the molten state, and then quickly butt and apply a certain pressure to make the two fully fused, and form a whole after cooling; electrofusion connection is to use the resistance wire inside the electrofusion pipe to generate electricity and heat, so that the contact surface between the pipe and the pipe is melted, so as to achieve tight connection. These two connection methods are based on the thermoplastic characteristics of PE materials, which can realize the combination of pipe and pipe fittings from the molecular level. The connection strength is high and the sealing is good. It is a reliable way to ensure the stable operation of PE pipe system.
