Now everyone's environmental awareness is improving, and the requirements of all aspects are also improving. Our commonly used steel mesh skeleton composite pipe has won public recognition by virtue of its own environmental advantages, and has developed rapidly. However, it is easy to rust when it is stored, which is a very troublesome problem. So today, I would like to introduce the method of composite pipe rust removal.
In order to achieve ideal derusting effect in maintenance, abrasives shall be selected according to the surface hardness, original rust level, required surface roughness, coating type, etc. of the steel mesh skeleton composite pipe. One layer of epoxy, two or three layers of polyethylene coating, the use of steel sand and steel shot mixed abrasive is easier to achieve the ideal derusting effect.
If the pipes used for building water supply and drainage, urban water supply and drainage, gas pipes and other fields are found to be damaged, the pipe lining method in situ can be adopted for repair. The internal throat sticking method is to insert a steel mesh skeleton composite pipe temporarily contracted or stretched into the old pipe, and then restore it to its original size and stick to the existing pipe.
In the blasting method, the old pipes will be blasted by pneumatic or hydraulic tools, and then a conical tool will be used to push the debris inside the pipe into the soil surrounding it. New products will be immediately laid in the tunnel formed by blasting. The above is the introduction of the rust removal of the steel mesh skeleton composite pipe. Once the product is rusted, if it is not handled in time, the product will be seriously damaged. Therefore, we can regularly check and derust the product according to the above methods. Only by removing the product in time can the original performance be restored for our use.
