一分彩Anticorrosion solution of anticorrosive tape on elbow steel pipe
At the present stage in China, many old pipelines are subject to anti-corrosion repair work. For straight pipes, we generally perform the operations of derusting-brushing anti-corrosive primer-winding polyethylene anti-corrosion tape or polypropylene anti-corrosion tape. However, some of the special-shaped pipe fittings, such as French valves and blind plates, may need to use viscoelastic paste, viscoelastic anticorrosive tape, and anticorrosive tape.
For straight pipe corrosion protection, as long as the width of the tape and the diameter of the steel pipe can be matched as required, normal and simple construction can be performed. But for slightly special pipes such as elbows, we need to do the following:
1. If the normal pipe diameter selection tape is 200mm wide, then 100mm or narrower tape should be used when selecting the tape for curved pipes.
2. Due to the special nature of the elbow, when the 55% overlap is overlapped in strict accordance with the requirements during winding, there will be wrinkles on the flat primer above. This requires us to perform artificial repair and use a blade to break the wrinkles. Open and overlap again in the original direction, and also need to take the same width of tape to repair the break, so as to avoid serious leakage problems in the spark detection.
Pay attention to the above two operations, I believe it will bring more convenience to your construction.
一分彩What are the commonly used bent pipe anticorrosive materials?
Due to different design requirements, the requirements for anticorrosive materials are also different. Some designs are 55% overlap of polyethylene anticorrosive tape, and some are made of polyethylene anticorrosive tape with an inner layer of polypropylene reinforced fiber anticorrosive tape. This is convenient for transportation. And easy to hang, some are directly wrapped on the surface of the pipe with viscoelastic anti-corrosion tape, the outer layer is wrapped with polyethylene anti-corrosion tape or polypropylene anti-corrosion tape and other external protective tape. Pipes exposed to the sun for a long time need to use aluminum foil anti-corrosive UV tape. Anticorrosive tape manufacturer
