Tips For Using Steel Pipes

Tips for using steel pipes mainly include the following aspects:

Tips for bending steel pipes: Steel pipe bending is a metal processing process that uses mechanical principles to make steel pipes plastically deform at specific positions to achieve the required bending angle and shape. Common bending methods include manual bending, mechanical bending, flame cutting bending and cold bending. Select appropriate bending methods and tools to ensure that the steel pipe has good plasticity and toughness, and conduct quality inspections on the bent steel pipes to ensure that they meet the use requirements.

Tips for vertical welding: Vertical welding refers to welding along the joint from top to bottom or from bottom to top, with a welding position with a weld angle of 90° or 270°. During vertical welding, the molten pool metal and molten droplets have a tendency to fall due to gravity, and weld nodules are prone to occur, but the slag has a low melting point and strong fluidity, and is not prone to slag inclusions. When welding, attention should be paid to the electrode angle and the operating skills during welding to ensure welding quality.

Installation and use of epoxy coated steel pipes: When installing epoxy coated steel pipes, avoid using high-speed grinding wheel cutters or gas cutting methods to avoid damaging the plastic layer or excessive extrusion. When processing threads, use thread machines, lathes or manual hinges, and ensure that the slotting machine, pipe bending machine and cold pipe bending machine are operated correctly to avoid damage to the plastic coating. In terms of connection methods, pipes with a diameter of 15mm-100mm can be connected by threads, and pipes with a diameter of 100mm or more should be connected by grooves or flanges. Key points of pipeline installation design: When designing pipeline installation, it is necessary to fully understand and master the design requirements, including the material selection, size specifications, layout planning and compatibility with related systems of the pipeline. The pipeline installation of the air conditioning water system must follow the key points such as the lowest and highest point design, valve configuration, support and hanger setting, and compensation expansion joint installation to ensure the safe, stable and efficient operation of the system.
