What Is a Plastic Expansion Joint?
A plastic expansion joint is a component used for connecting pipes in various construction projects. Commonly used in DIY projects, these joints facilitate the connection of pipes at right angles or for extending lengths. Available in removable and fixed (adhesive-injected) types, plastic expansion joints are lightweight, waterproof, and suitable for outdoor use.
Uses of Plastic Expansion Joints
These joints are instrumental in creating furniture and other items from pipes. They are widely used in DIY projects, including constructing car and motorcycle garages, agricultural greenhouses, and home-use greenhouses. Their ease of assembly and transportability make them ideal for outdoor camping tents and table sets. Plastic expansion joints are also utilized in industrial settings for making hand carts and other factory equipment.
Principle of Plastic Expansion Joints
The pipes connected using plastic expansion joints are known as “erector pipes.” These joints allow for the versatile assembly of these pipes in various directions. Erector pipes, being steel pipes coated with plastic, offer waterproof and rust-resistant properties, making them suitable for outdoor applications. The term “erector” comes from the concept of building or assembling structures.
Erector pipes are available in diameters of 28 mm, 32 mm, and 42 mm, providing options based on the project’s requirements. Plastic expansion joints are tailored to fit these specific diameters and come in a variety of colors. When securing joints to erector pipes, special adhesives may be used. It’s important to clean the joint surface of water, oil, or dust to prevent corrosion or rust over time.
