Understanding of anticorrosive tape in pipeline anticorrosion
With the gradual aging of the domestic petroleum pipeline network, some problems of the anticorrosive layer of petroleum pipelines have also been manifested accordingly, mainly reflected in the damage of the asphalt anticorrosive layer. In some cases, the pipeline will cause corrosion and directly affect the operation of the pipeline. Now we will discuss with Jining Xunda a few points about the work of anticorrosive tape over the years.
1. Civil engineering excavation
一分彩 At present, the general situation is to use mechanical and manual excavation, which can improve work efficiency, but pay attention to the following things: Due to the current piracy activities of oil stealing molecules, first, a line inspector who is familiar with the pipeline must cooperate Guide the excavator to guide and determine the excavation depth, and one person will excavate the pit in advance, especially on both sides of the rural road or where it seems to be hidden but can pass through large vehicles. Manual excavation is required to prevent accidents. accident.
一分彩When the soil is relatively soft and the pipeline is buried deep, it must be excavated above the pipeline when digging. When manually cleaning the bottom of the ditch, there must be 2 or more people, and the position of the personnel should not stand on one side during work. It is strictly forbidden to stand on the soil edges on both sides of the construction.
一分彩During the pipeline's pigging process, it is easy to see that the outer anticorrosive layer is peeled off, and the surface of the pipeline has a thin and sticky asphalt layer. A good method is to soak the part to be removed with diesel rags with diesel oil. After 2 to 3 hours, it can be removed more easily with a small spatula. But don't worry about the excessive waste of oil. In fact, if you clean up the oil layer outside the pipeline once, you can save a lot of fuel oil used for soaking with diesel and gasoline. If there is a lot of sand, you can use a rag dipped in fine sand to clear the pipe. In this way, not only the cloth and oil are saved, but also the pipeline is cleaned. With the above method, the pigging process is fast and saves.
Polypropylene anticorrosive tape degumming is a technical problem often encountered by construction personnel when using anticorrosive tape, which directly affects the use of the product. Polypropylene anticorrosive tape uses butyl rubber modified asphalt as the anticorrosive layer. During its use How should I deal with the degumming of polypropylene anticorrosive tape? The polypropylene anticorrosive tape manufacturers will introduce several methods to everyone.
1. We can change the roller of the polypropylene anticorrosive tape base film equipment to produce a film with a rough substrate surface and a smoother backing surface. We can also increase the roughness of the base surface of the polypropylene anticorrosive tape first. Increase the smoothness of the backing surface.
一分彩2. Before using polypropylene anticorrosive tape, the construction personnel should pre-treat the product. Polypropylene anticorrosive tape manufacturers remind everyone to put a stove in the room where the tape is stored to increase the indoor temperature. Or put the tape in the sun before construction.
