Metal conduit, also known as metal threading pipe, is a type of protective piping designed to safeguard electrical wiring in harsh environments such as those with strong acids, alkalis, and corrosive substances. It offers excellent resistance to acid, alkali, and corrosion, making it a widely used solution in industrial applications. Understanding the proper installation methods is essential for ensuring both safety and compliance. Here’s a detailed look at how metal conduits are constructed and installed. (1) When cutting JDG pipes, use a hacksaw or a diamond blade saw to ensure a clean, smooth cut without any burrs. This helps maintain the integrity of the pipe and prevents damage to the wires inside. (2) For concealed installation of JDG pipes, the bending radius should not be less than six times the outer diameter of the pipe. In concrete surfaces, this minimum radius increases to ten times the outer diameter. If there's only one bend between two junction boxes, the bending radius should still be at least four times the pipe's outer diameter. (3) When installing JDG conduits in walls or ceilings, the spacing between fixed points should not exceed 1000mm. Additionally, the distance from the fixed point to elbows, junction boxes, or terminal ends should be more than 150mm but less than 300mm to ensure stability and prevent sagging. (4) When burying metal threading pipes in walls or concrete, maintain a clearance of at least 15mm between the pipe and the surrounding surface. This prevents damage during construction and allows for easier maintenance in the future. (5) For suspended installations, if no specific design requirements are provided, the support brackets and hangers must meet certain standards. For example, round steel should be at least 6mm in diameter, flat steel should be 30mm x 3mm, and angle steel should be 25mm x 25mm x 3mm. (6) When connecting pipes to junction boxes, each pipe should enter through a single hole that matches the size of the pipe. Never modify the box by enlarging the hole. The arrangement should be neat, evenly spaced, and the box should sit flush against the wall for a professional finish. (7) After completing the piping, it’s important to seal the open ends of the conduits to prevent dust, moisture, or other foreign materials from entering, which could compromise the wiring system. (8) During concrete pouring, an electrician should be on-site to monitor the installation and prevent the conduits or junction boxes from shifting or becoming misaligned due to vibration. (9) Once the formwork is removed, perform a preliminary inspection to ensure the conduits are properly aligned and secured along the marked lines.
