Instructions for using winding machine equipment for polyethylene adhesive tape

Winding machine: Pipe anti-corrosion tape winding machine is a commonly used machine in anti-corrosion and insulation projects. The principle is very 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 the steel pipe rotation can be controlled by controlling the speed of the gear rotation, thereby controlling the tension and speed of the tape winding.

How to use winding machines in construction

The anti-corrosion tape manufacturer tells you how to use winding machines in construction: After the steel pipe is surface treated and rust-free, and painted with anti-corrosion primer, after the surface is dry, the starting end of the adhesive tape is attached to the starting point of the steel pipe. The constructor tightens the tape and the pipe is driven mechanically As it rotates, according to the requirements of the overlap ratio, the adhesive tape follows the rotation of the steel pipe and the adhesive tape adheres tightly to the surface of the steel pipe. It is suitable for when the project volume is relatively large and can better keep up with the construction progress. The construction is simple and fast, and the winding quality is uniform.

Precautions

When selecting an adhesive tape wrapping machine, the construction party needs to choose wrapping machines of different power models according to the size of the pipe diameter. Generally speaking, pipe diameters below 500mm are one grade, and pipe diameters between 500mm and 1000mm are another grade. Pipe diameters above 1000mm are the third level. If the pipe diameter is above 2000mm, the winding machine needs to be customized. Because these models are generally uncommon, the price of high-power winding machines is generally relatively high.

Use appropriate machinery or hand tools to spirally wrap the tape on the primed pipe according to the overlap requirements. The tape should maintain a certain tension so that the tape layers are tightly connected. When wrapping the tape, the edges of the tape should be parallel and should not be twisted or wrinkled. There should be an overlap of more than 100 mm at the junction of the tapes at both ends. If necessary, apply primer or fully bake on the base film at the end of the previous section of tape. After the surface is dry, overlap the starting end of the other section of tape. The beginning and end should be pressed tightly with a wooden round tool to prevent them from warping.

During the winding construction of the polypropylene reinforced fiber anti-corrosion tape produced by the polyethylene anti-corrosion tape manufacturer, whether manual winding, manual mechanical winding, manual winding machine winding or mechanical transmission winding is used, the tape must have a certain tension, that is, it must have Winding construction is carried out under a certain tightening force (generally, the tightening force is 10-20N/CM).

三. Anti-corrosion pipe protection

1. Anti-corrosion pipes must not be handled until the anti-corrosion layer is fully dry.

2. When loading and unloading anti-corrosion pipes, only soft slings should be used to contact the anti-corrosion layer.

3. When stacking anti-corrosion pipes, sandbags or wooden pads should be placed at both ends and in the middle of the pipes to isolate the outer walls of the pipes and the pipe surface from the ground.

4. Anti-corrosion pipes should be buried in the ground in time for use. If they are stored for more than one month, they should be covered with tarpaulin to avoid sunlight and rain. If they are stored for more than half a year, they should be painted with a layer of epoxy coal tar topcoat before use.
