The installation of copper pipe generally follows the following process:
I. Preparation before installation
1. Material preparation: select the appropriate specifications and quality of copper pipe, as well as supporting fittings, valves, welding materials.
2. Tool preparation: such as pipe cutter, pipe bender, flare, welding equipment.
Measurement and discharging
1. according to the design requirements to measure the length of the required copper pipe, the use of pipe cutters to accurately discharging, to ensure that the kerf is flat, burr-free.
Bending
1. If you need to change the direction of the copper pipe, you can use the bender to bend. When bending, pay attention to control the bending radius to avoid excessive bending resulting in deformation or rupture of the copper pipe.
Flaring
1. For the end of the copper pipe to be connected, carry out the flaring operation. Use a flaring device to expand the mouth into a specific shape, in order to connect with the fittings.
V. Connections
1. Welding connection: adopt the brazing method to weld the copper pipe with the pipe fittings. Before welding, we should clean up the pipe mouth to ensure that the welding part is clean, use suitable solder and welding equipment, control the welding temperature and time to ensure the quality of welding.
2. Threaded connection: For pipe fittings with threads, threaded connection can be used. Wrap sealing tape or apply sealant before connection to prevent leakage.
VI. Fixing and supporting
1. Fix the installed copper pipe, use pipe clamps, hangers and other fixing devices to ensure that the copper pipe will not be shaken or shifted in the process of use.
2. Set up support at appropriate position to reduce the weight and stress of the copper pipe as needed.
VII. Pressure test and leakage detection
1. After the installation is completed, conduct a pressure test on the copper pipe system, generally using nitrogen or compressed air for pressure testing.
2. Check whether there is any leakage in each connection part, if there is any leakage, repair it in time.
Cleaning and protection
1. clean the surface of the copper pipe dust, oil and other impurities, to keep the copper pipe clean and tidy.
2. Anti-corrosion treatment or protective measures can be taken to extend the service life of the copper pipe.
