Huashida 3PE dedicated heat shrink sleeves have gained the trust of customers with their reliable quality. The construction process specification is as follows: Before the pipes are joined, the heat shrinkable sleeve is first inserted. After the welding is qualified, the weld bead is cleaned, the sleeve is moved to the center of the weld bead and the isolation paper is removed to ensure that both ends overlap with the original covering position by more than 80mm. Start heating in a spiral manner from the center of the sleeve to both ends. After the heat shrinkage is completed, gently press and smooth it out with gloves or a roller. Then, reheat the entire sleeve to prevent air residue. Fixed plates are widely used in 3PE wound repair and mouth repair. When applying the solvent-free epoxy primer, rust and dirt removal should be carried out in accordance with the GB/T8923 standard. The components A and B should be mixed evenly in proportion and applied to avoid missed coating and sagging. Construction should be carried out in an environment with a temperature ranging from -5 to +50°C, good ventilation and a humidity of no more than 85%. Protective measures should be taken in rainy, snowy, foggy or windy weather.
