Advantages of Datong Tianzhen Heat Shrink Tape Specifications


</ p> <p> The advantage of Datongtianzhen heat shrinkable tape products is that the use of heat shrinkable tape and heat shrinkable tape is very different in terms of flexibility. The former is generally used before the product is welded. , While the latter is more flexible and can be used at any time. It is mainly used for buried steel pipelines such as oil and gas transportation, chemical industry, urban construction water supply and drainage, gas transmission, etc. It is easy to construct and pollution-free. For more than 60 years, polyethylene tape has been used as an external material in oil and gas steel pipelines for more than 40 years. Due to its excellent performance and convenient construction performance, it occupies a certain position in pipeline materials. With the continuous improvement and improvement of the variety and quality of polyethylene tapes, the application fields of polyethylene tapes have continued to expand. . With the rapid economic development, the application prospect of heat shrinkable belts in oil and gas pipelines is increasing, and there is an increasing demand for long-distance oil pipelines, gas pipeline projects, and urban gas pipeline networks. During the "" period, long-distance oil and gas pipeline projects will exceed 20,000 kilometers. The city gas pipeline network project is nearly 30,000 kilometers. The demand for heat shrinkable belts exceeds 3O, and there are few good domestic qualified companies. The application prospect of heat shrinkable zone in buried oil pipeline is broad. The heat shrinkable tape series products are designed for buried and overhead steel pipeline welding joints and thermal insulation joints of thermal insulation pipes. It is a composite of radiation-crosslinked polyolefin substrate and special sealing hot-melt adhesive. The special sealing hot-melt adhesive can form a good bond with polyolefin substrate, steel pipe surface and solid epoxy coating. In the industry, the heat shrinkable tape is called a loose sleeve. Compared to the heat shrinkable sleeve called a dead sleeve, in addition to the main body of the heat shrinkable tape, it is also equipped with a rubber strip and a fixing sheet. The heat shrinkable tape is convenient for large-scale and convenient construction. a lot of. When the WK-WSS heat shrinkable tape is heated and installed, the base material shrinks in the radial direction, and the internal composite rubber layer is melted, tightly covering the joint, and the base material becomes a solid body in the shape of the pipe. Excellent abrasion resistance, corrosion resistance, impact resistance and good resistance to ultraviolet and light aging. The heat shrinkable zone began to be applied to the long-distance transportation of oil and gas steel pipe joints in the oil and gas industry in the middle and late years. At the beginning of this century, it was widely used in long-distance oil and gas pipe joints, urban gas pipe network joints, heating pipe joints, and tap water Pipe seams and other areas. The meaning of this paragraph is from the meaning of steel pipes. The current status of corrosion of oil and gas pipes Introduction to heat shrink sleeves for oil and gas pipes, requirements for heat shrink bands for oil and gas pipes, and the application prospects of heat shrink bands in the oil and gas industry The aspect describes the application of heat shrinkable tape in steel pipes. Engineering materials commonly used materials such as high-chlorine coatings such as MX53-4 various high-chlorinated polyethylene topcoats (indoor and outdoor type), high-chlorinated polyethylene iron red anti-rust paint, MX53-2 high-chlorinated polyethylene anti-rust iron paint, MX53-3 high chlorinated polyethylene mica iron intermediate paint chlorosulfur coating, such as J52-4 chlorosulfonated polyethylene cooling tower moisture-proof paint (bottom / surface, two-component), J52-5 chlorosulfonated polyethylene gas tank special paint (Bottom / middle / surface, two-component), J52-6 chlorosulfonated polyethylene pipe coating (bottom / surface, two-component silicone coating such as MW-600 silicone high temperature resistant coating (bottom / surface, two-component) ), MW-700 silicone heat-resistant coating (bottom / surface, two-component) Datong Tianzhen Except for the two more important recycling parts we mentioned above, other heat shrinkable belt parts are used as The waste that is disposed of does not need to be recycled and reused. Even if the recycler transports it away, it will not receive the related recycling costs. If you want to find a person who specializes in recycling this kind of heat shrinkable tape, please consult the specific one first. If the given situation is acceptable based on what is said, then there will be a subsequent heat shrink belt recovery process. The repair of this steel pipe is generally required to be cleaned before the repair. The burrs, welding slag, dirt, oil and other debris in the circumferential weld and its vicinity are cleaned up. The surface of the repaired joint is removed. The quality of rust treatment and surface derusting treatment should reach the level of rust and derusting of the steel surface before painting. Hot-melt coated cold-wound tape: Polyethylene film, glass fiber cloth, polypropylene braid or plastic coated non-woven fabric is used. The base material is coated with the modified base material after heating and melting with modified bitumen. Modified bitumen is made by adding a small amount of thermoplastic such as SBS to petroleum bitumen to improve the temperature property of bitumen. Performance and temperature resistance are greatly improved compared with the previous asphalt glass wool cloth, and the bonding strength is great. Because 80% of the adhesive layer material of this tape is asphalt, its construction temperature should be between 5 ℃ and 50 ℃. In the meantime, when the temperature is lower than 5 ℃, the asphalt adhesive layer of such tapes will become hard and lose its tackiness. When it is higher than 50 ℃, the asphalt adhesive layer is liable to overflow and flow. The adhesive layer is isolated from the substrate. When the base material of this type of tape is fabric, because it has grid voids, its electrical insulation strength is only 50% of that of polyethylene-based film tape, so the thickness of the tape is usually more than 1 mm. It should be in good environmental conditions and small temperature changes. The product range Daqing tape is a kind of metal foil or conductive cloth with highly conductive adhesive. The conductive adhesive and conductive substrate form a complete conductor, which can be bonded to any metal surface to complete electrical lapping. Electrical sealing of gaps and gaps. Conductive tape is an economical and easy-to-use material. The advantages of Datongtian heat shrink tape specifications are that the surface of the pipe is difficult to uniformly heat, especially when the pipe diameter is large, which causes uneven shrinkage of the shrinkage band and buried pipes. After the ground, the shrinkage zone is still creeping and losing the adhesion with the pipeline; it is not easy to judge the construction quality from the appearance, and it requires high quality of the operator, it is difficult to guarantee the quality; once the moisture enters the shrinkage zone, because Cathodic protection cannot function due to the current of the shrink band, and corrosion cannot be prevented. Product survey 6 The prefabricated pipes shall be subjected to quality inspection in accordance with the requirements of this standard 8. After the inspection is qualified, a certificate of conformity shall be delivered to the user. Consumption </ p> <p>

Advantages of Datong Tianzhen Heat Shrink Tape Specifications


</ p> <p> The advantage of Datongtianzhen heat shrinkable belt specifications lies in the current status of folding corrosion. According to statistics, in pipelines, corrosion accounts for about 30%. Corrosion of various types of pipelines in several oil fields in the east reached 20,000 times / year, and the number of pipelines replaced was 400 km / year. Sichuan natural gas pipeline, from May 1971 to May 1986 15 years due to corrosion caused a total of 83, economic losses amounted to more than 600 million yuan. Integrity management 4 The use of machinery is a powerful measure to ensure the quality of tape winding. It is difficult to achieve uniform surface quality and consistent tension with hand-wound tape. Manual winding can only be used in special circumstances when mechanical construction cannot be performed. , But use narrower tape. Customer-oriented types of heat-sealing tapes: PV compound PU, pure PU (TPU), hot-melt film, rubber tape, non-woven tape, layered tape. Anti-rust grease is composed of adding one or more anti-rust additives (also known as oil-soluble corrosion inhibitors) and its auxiliary additives to the basic components of petroleum. It is easy to use, low cost, good effect, simple operation, and fasteners. The industry is using it a lot. Sand blasting and derusting Sa1 level light sand blasting and derusting should be free of visible grease, dirt, loosely attached oxide scale, rust, paint coatings and other impurities.
