Application range of polypropylene anticorrosive tape
Polypropylene anti-corrosion tape is a new type of anti-corrosion tape which is made by laminating a layer of special modified asphalt adhesive with polypropylene woven fiber cloth base material. It represents the high level of international and domestic cold-wrapped anti-corrosion tape today, and has the "crown of anti-corrosion" "Good reputation. Its bonding structure principle is similar to that of polyethylene anticorrosive tape, except that its base material is a fibrous structure, which can effectively resist the creep damage caused by soil stress. The aging test has proved that its corrosion resistance life is more than 50 years, and the price is cheap. , Is an intact pipe anticorrosive material. Today, Xunda Anticorrosive Materials Co., Ltd. will introduce some common occasions of polypropylene anticorrosive tape, so that you can understand this product more intuitively.
Polypropylene reinforced fiber anticorrosive tape can be used as an outer anticorrosive layer with pipes. Generally, petroleum pipelines still have certain corrosive media due to transportation, and the outside is easily polluted by such media. If steel pipelines directly contact these media, they will accelerate the corrosion of steel pipes and even form corrosion perforations. If crude oil pipelines are buried, they will also be affected by soil The environment is corrosive, so the exterior of oil pipelines must be anticorrosive. At present, polypropylene reinforced fiber anticorrosive tape is a commonly used anticorrosive material for petroleum pipelines. The anticorrosive effect is also very good, the price is low, and the construction is simple. It is more popular among designers and constructors.
Many kinds of liquid raw materials in chemical plants are transported by pipelines. Because many materials are actually very corrosive, for steel pipelines, such as pipelines that transport concentrated hydrochloric acid, in order to stop external weather conditions, especially chemical The leakage of raw materials corrodes the steel pipe. If the chemical pipeline has a buried part, it will also be corroded by the soil environment. Effective corrosion protection measures must be taken on the outside of the steel pipe. Polypropylene reinforced fiber anticorrosive tape has become a cheap and effective chemical pipeline anticorrosive material.
一分彩Polypropylene fiber anticorrosive tape has become a popular anticorrosive material for buried pipelines due to its good pipeline anticorrosive effect. However, the quality of its products is currently uneven on the market, and consumers will accidentally buy poor-quality polypropylene fiber anticorrosive tapes. Therefore, in order to avoid the above phenomenon, the technical staff of our company will teach you how to judge the quality of polypropylene fiber anticorrosive tape.
The appearance of the polypropylene fiber anticorrosive tape determines the winding quality of the tape, so the surface should be flat, overlapped uniformly, no wrinkles, no protrusions, and no rupture points are allowed. In addition, the tape sometimes generates bubbles during the winding process. This often occurs when the weather is hot and sunny. Because the tape itself has a certain degree of elasticity and self-repairing ability, these bubbles can disappear on their own, and this type of bubbles may not be a quality problem. If air bubbles are generated, like wrinkles, this is the quality of the tape itself.
一分彩The thickness index has a great effect on the quality of anticorrosion. The increase of the thickness of the polypropylene fiber anticorrosive tape can enhance its anticorrosive ability. When the structure of the tape is determined, its thickness is determined, so the thickness of the tape is measured in advance, and the total thickness can be determined. However, in order to prevent insufficient thickness caused by the use of different batches of tape, the inspector can use a thickness gauge to measure the pipeline after construction.
一分彩The peeling strength refers to the adhesion of the anticorrosive layer to the steel pipe. Its strength directly affects the quality of the anticorrosive layer, and its size directly affects the water permeability. Therefore, when using polypropylene fiber anticorrosive tape, it should ensure that it has sufficient adhesion.
EDM Leak Detection:
一分彩This indicator mainly controls the defects during construction or certain defects in the tape, and the entire pipeline must be inspected. The leak detection voltage is the same as the petroleum asphalt leak detection formula. The leak detector's moving speed does not exceed 0.3m / s. All discharge places should be marked and repaired with tape. Record the test results, including the shape, nature and location of defects, repair processes, etc., as the pipeline completion data.
