1. Preparation before welding 1. Equipment inspection Check whether the power cord of the butt welding machine is connected correctly and without damage, ensure good grounding, and

1. Leak detection First, you need to determine the location of the leak. You can locate the leak by observing the wet marks on the surface of the pipe, listening to the sound of th

1. Choose high-quality materials Select high-quality, standard HDPE pipes and fittings to ensure that the raw materials have good corrosion resistance, aging resistance and mechani

1. Soil properties Acidity: Overly acidic or alkaline soil environments may accelerate the corrosion of pipes. Resistivity: When the soil resistivity is low, electrochemical corros

1. Preparation Make sure the pipe ends are flat, clean, and free of oil, dust, and debris. Select a suitable welding machine and check its performance and status. 2. Fix the pipe U

1. Preparation Check whether all parts of the welding machine are intact and whether there is any damage or looseness. Prepare the pipes to be welded and ensure that their surfaces

When preparing for welding, place the two workpieces to be welded (usually metal pipes, bars, etc.) in the fixed fixture of the welding machine to ensure that their butt joints are

The temperature and pressure calibration cycle of the socket welding machine usually does not have a fixed standard, but is affected by many factors. Generally speaking, if the soc

Temperature calibration: 1. Preheating time: Before measuring the temperature, make sure that the heating plate has enough preheating time to reach a stable working temperature. 2.
