《海鑫鋼鐵》10月13日記者獲悉,Epoxy coal tar pitch anticorrosive steel pipe is mainly used for the external wall anticorrosion of buried or underwater steel pipelines for oil, gas, water supply and heat supply. It is also suitable for anticorrosion of various steel structures, wharfs, ships, sluices, gas storage tanks, petrochemical plant equipment and concrete pipes, sewage tanks, roof waterproof layer, toilets, basements, etc. Waterproof and leakproof structure. It can be said that the application of epoxy coal tar pitch is very extensive, the performance after drying is also very good, but in storage and use, it is easy to deteriorate because of high temperature or humidity, so it should be away from the heat source or open fire before drying, and can not be exposed in a humid environment. It is widely used in underground oil pipelines, such as epoxy coal tar pitch anticorrosive steel pipe, which is a pipeline facility with the main structure of steel pipe and epoxy coal tar pitch coating. Its performance is quite good. It can effectively transport related media in underground environment, has high efficiency, and has good resistance to various corrosion. Commonly used underground pipelines.Appearance of epoxy coal tar pitch anticorrosive steel pipe: Primer A component iron red, B component black, top paint are black. With excellent corrosion resistance of chemical media and good physical and mechanical properties, good adhesion, film toughness, and excellent electrical insulation and anti-permeability, anti-stray current and anti-microbial erosion, film formation, can reduce the number of construction channels. The main implementation standards are "Technical Standards for Epoxy Coal Asphalt Coatings for Buried Steel Pipelines" and "Technical Standards for Liquid Epoxy Coatings for Steel Pipelines". Mainly used for buried or underwater steel oil, gas, water supply, heat supply pipeline wall anticorrosion, but also for all kinds of steel structures, wharfs, ships, sluices, gas storage tanks, petrochemical plant equipment anticorrosion and concrete pipes, sewage tanks, roof waterproof layer, toilets, basements and other concrete structures waterproof and leakage prevention . Epoxy coal tar pitch anticorrosive steel pipe manufacturer - process introduction epoxy coal tar pitch anticorrosive steel pipe manufacturer epoxy coal tar pitch anticorrosive steel pipe using two-component atmospheric temperature curing type of coating, on the surface of the steel pipe by glass cloth as a reinforced coating from the anticorrosive.

中石油綦南輸氣管線正式接入中石化南川頁巖氣開采區(qū)
近日,中石油綦南輸氣線正式接入中石化南川頁巖氣開采區(qū),這是中石油與中石化兩家企業(yè),在川渝地區(qū)頁巖氣上,首次實現(xiàn)互聯(lián)互通。這樣一來,本地生產(chǎn)的清潔能源能更加便捷高效地輸往我市各地,而市民與企業(yè)的用氣也會更有保障。
目前,在中石化南川頁巖氣輸出站與中石油南川配氣站之間,建起了30公里的華南互通線,使用多年的中石油輸氣管線延伸進(jìn)入到中石化開采區(qū)內(nèi)。由此,臨近地區(qū)的用氣,不再因為管道“繞路”,而出現(xiàn)供氣不足的情況。
據(jù)介紹,這是川渝地區(qū)在頁巖氣上,第一條實現(xiàn)互聯(lián)互通的輸氣管線,它能有效整合中石油、中石化各自的區(qū)域管網(wǎng)與產(chǎn)能優(yōu)勢,整體提升我市管網(wǎng)供氣的靈活性。與此同時,我市產(chǎn)出的頁巖氣新能源,也能更加高效利用,更有效地輸出。
