Operation process and key points: Use an angle grinder to clean out the burrs, welding slag, rust, residual coating, sludge, etc. on the exposed steel pipes at the pipe joints. Be sure to clean them so that the surface is smooth and up to grade. The bevels on both sides of the joint are roughened. The width of the roughening of the polyethylene layer on each side is controlled to ~ including the bevel. When roughening the coating, the coating must not be damaged to expose the substrate. Use a brush to clean away the cleaned debris. Be sure to clean it thoroughly, otherwise it will affect the bonding force of the repair layer. If the repair area is damp or contains moisture, measures must be taken to dry it before pre-treatment. The time interval between pre-treatment and priming shall not exceed 1 minute. If the pre-treated area is contaminated twice during the interval, pre-treatment must be carried out again. Apply the primer according to the instructions for use of the primer, mix the two components and thinner in proportion, and stir evenly. Dip a brush into primer and apply to the exposed areas of the pipe connections. The thickness of brushing should just cover the base material. The general thickness is ~~, and the base material is not allowed to be exposed or exceed the thickness. The exposed epoxy coating at the groove should be primed, but the polyethylene layer should not be primed. After the primer is dry, the heat shrink sleeve can be wrapped. If the primer is slow to dry, you can use electric heating bulbs to accelerate the drying. Do not use fire or other methods to speed up the drying, otherwise the paint film will be damaged and the bonding force will be affected. It is recommended to carry out external repairs immediately after welding. Using the residual heat of welding can ensure that the pre-treatment is above the dew point and speed up the surface drying of the primer. However, the temperature at the welding point should be lowered below 10°C before construction. After applying the primer, clean the brush with thinner and prepare it for next use. Wrap the heat shrinkable sleeve. Wrap the heat shrinkable sleeve immediately after the paint film is dry. The interval should not exceed 1 minute. The width of the heat shrink sleeve should ensure that it can completely cover the roughened parts on both sides after wrapping. Generally speaking, the thickness should be greater than the width of the exposed part of the steel pipe + the width of the roughened parts on both sides~. Remove the film or kraft paper on the heat shrink sleeve, and heat the hot melt adhesive surface within the length of one end of the heat shrink sleeve with the flame of a baking gun to ensure that the edges and corners are evenly heated. Stop heating immediately when the hot melt glue becomes soft and shiny, and then quickly press one side of the melted hot melt glue onto the joint. The heat shrink sleeve should completely cover the roughened areas on both sides, and use a roller to roll from the center line to both sides. , drive away the bubbles in the bonding area and fix it. When heating, avoid overheating, otherwise it will destroy the hot melt adhesive layer and affect the adhesion. Wrap the heat shrink sleeve around the circumference of the pipe. Be sure to tighten it when wrapping, and keep the center line of the heat shrink sleeve parallel to the pipe connection gap. Then bake the hot melt adhesive layer on the other end of the heat shrink sleeve until it becomes soft and shiny, and then quickly attach it to the front end. Overlap length requirements exceeded. Quality requirements require that the surface of the heat shrink sleeve should be smooth, wrinkle-free, bubble-free, and have no charring or carbonization on the surface. The heat shrink sleeve fits closely with the anti-corrosion layer of the original groove of the circumferential weld without any gaps. The overlap between the heat shrink sleeve and the coating should be no less than 1, and the circumferential overlap of the heat shrink sleeve should be no less than 1. After cooling, the hot melt adhesive should overflow evenly on both edges of the heat shrink sleeve. For other requirements, please refer to B
