Winding machine: Pipe anti-corrosion tape winding machine is a commonly used machine in anti-corrosion and insulation engineering. The principle is simple: it uses gear rolling to drive the steel pipe to rotate, which facilitates the winding of the tape. At the same time, the frequency of rotation of the steel pipe can be controlled by controlling the speed of gear rotation, thereby controlling the tension and speed of the tape winding.
The anti-corrosion tape manufacturer tells you the specific construction method: After the steel pipe is surface-treated to remove rust, and coated with anti-corrosive primer, after the surface is dry, the starting end of the adhesive tape is attached to the starting point of the steel pipe. During the rotation, according to the requirements of the overlap ratio, the adhesive tape closely adheres to the surface of the steel pipe with the rotation of the steel pipe. It is applicable when the amount of work is relatively large, and it can better keep up with the construction progress. The construction is simple and fast, and the winding quality is uniform.
一分彩Second, matters needing attention
When selecting an adhesive tape winding machine, the construction party needs to choose a winding machine of different power models according to the size of the pipe diameter. Generally, the pipe diameter below 500mm is one grade, and the pipe diameter of 500mm-1000mm is another grade. Pipe diameters above 1000mm are the third grade. If the pipe diameter is more than 2000mmm, the winding machine needs to be customized. Because these models are generally not common, the prices of high-power winding machines are generally relatively high.
一分彩Polyethylene anticorrosive tape manufacturer
Use appropriate mechanical or manual tools to spirally wrap the tape on the primed pipe according to the overlap requirements. The tape should maintain a certain tension to make the tape layers tightly connected. When winding the tape, the seam of the tape should be parallel, and the wrinkles must not be twisted. There should be more than 100 millimeters of overlap between the two ends of the tape. If necessary, apply primer or fully bake the end base film of the previous section of tape. After the surface is dry, overlap the beginning of the other section of tape. The beginning and end should be pressed tightly with a wooden smooth tool to prevent it from tilting.
In the winding construction of polypropylene reinforced fiber anticorrosive tape made by polyethylene anticorrosive tape manufacturers, no matter whether manual winding, manual mechanical winding, manual winding machine winding, and mechanical transmission winding are used, the tape must have a certain tension, that is, there must be Winding construction under a certain tension (in general, the tension is preferably 10-20N / CM).
Third, anti-corrosion pipe protection
一分彩1. The anti-corrosion pipe shall not be transported when the anti-corrosion layer is not dry.
一分彩2. When loading and unloading anti-corrosion pipes, only use soft slings to contact the anti-corrosion layer.
3. When stacking anticorrosive pipes, sand bags or wooden mats should be placed at both ends and in the middle of the pipes to isolate the outer walls of the pipes and the surface of the pipes from the ground.
一分彩4. The anti-corrosion pipe should be buried in time. If it is stored for more than one month, it should be covered with tarpaulin to avoid sun and rain. If it is stored for more than six months, it should be painted with an epoxy coal asphalt topcoat.
