Shrink Band Construction Technology In the construction process of pipes, Shrink Band is an indispensable anti-corrosion product, because of its good anti-corrosion performance, it is widely used in many places, but in order to ensure the construction quality, we need to understand the construction process of heat shrinkable tape. 1. Rust removal a. Referring to the requirements of SY/T0407, clear the oil, grease and other sundries on the anti-corrosion parts of the derusting machine. b. When the weather is humid, preheat the steel pipe to 50 degrees before derusting. Rust removal level: Sa2.5 or St3.0 level. c. Trim the outer anti-corrosion layer at both ends of the weld to a slope, and use emery cloth or wire brush to roughen the overlapping parts. 2. Tube preheating a. Adjust the torch to medium heat to bake and preheat the steel body. The preheating should be uniform, not too fast, and the temperature around the steel pipe should be kept consistent. b. The preheating temperature is controlled and maintained at 60-80 degrees. Generally, the preheating time should not be less than five minutes, and the steel pipe with a large diameter will take longer. c. Use a thermometer to sample and measure the temperature around the steel body. Do not measure the bare steel directly when measuring the temperature. The actual temperature measurement is to paint a little primer on the bare steel to measure the temperature of the primer.
