《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. It can be used for anticorrosion of the outer wall of buried or underwater oil, gas, water and thermal pipelines. It can also be used for anticorrosion of various steel structures, wharfs, ships, sluices, gas storage tanks, equipment in petrochemical plants and leakage prevention of sewage tanks, roof waterproof layers and basement concrete layers.
環氧煤瀝青防腐鋼管主要用于埋地或水下鋼質輸油、輸氣、供水、供熱管道的外壁防腐,也適用于各類鋼結構、碼頭、船舶、水閘、煤氣儲罐、煉油化工廠設備防腐及混凝土管、污水池、樓頂防水層、衛生間、地下室等混凝土結構的防水和防滲漏??梢哉f環氧煤瀝青的應用是非常廣泛的,干燥后的性能也十分優,但是在儲藏和使用時,卻很容易因高溫或潮濕而發生變質,因此在其干燥成型前都要遠離熱源或是明火,也不能在在潮濕的環境中暴露。地下輸油管道中對它的應用十分普遍,比如環氧煤瀝青防腐鋼管,就是鋼管與環氧煤瀝青涂層為主要結構的管道設施,性能相當不錯,在地下環境中能有效運輸相關介質,效率高,對各種腐蝕都有良好的抵抗能力,是一種較為常用的地下輸油管道。環氧煤瀝青防腐鋼管外觀:底漆甲組分鐵紅色,乙組分黑色,面漆均為黑色。具有優異的耐化學介質腐蝕性和良好的物理機械性能,粘結力好,涂膜堅韌,并有優異的電絕緣性和抗滲透性,抗雜散電流和抗微生物侵蝕性,成膜后,可減少施工道數。主要的執行標準《埋地鋼質管道環氧煤瀝青防腐層技術標準》和《鋼質管道液體環氧涂料內防腐層技術標準》。主要用于埋地或水下鋼質輸油、輸氣、供水、供熱管道的外壁防腐,也適用于各類鋼結構、碼頭、船舶、水閘、煤氣儲罐、煉油化工廠設備防腐及混凝土管、污水池、樓頂防水層、衛生間、地下室等混凝土結構的防水和防滲漏。環氧粉末防腐鋼管生產廠家-工藝介紹 環氧煤瀝青防腐廠家環氧煤瀝青防腐鋼管采用雙組分常溫固化型的涂料,在鋼管表面上由玻璃布作為加強涂敷而成的防腐。可用于埋地或水下的輸油、輸氣、輸水、熱力管道的外壁防腐,也適用于各類鋼結構、碼頭、船舶、水閘、煤氣儲罐、煉油化工廠設備防腐及污水池、樓頂防水層、地下室混凝土層的防滲漏。在管道外壁涂刷中,與玻璃纖維布包扎配套使用,成為加強級或特加強級涂層,防腐性能優異。三布四油防腐鋼管是由涂料與玻璃纖維布復合使用,這樣使用可增強防腐層的機械性能。三布四油具有優異的電絕緣性、抗水滲透性、抗微生物侵蝕、抗雜散電流、耐熱、耐溫差驟變等優良性能,供水管線內腐蝕介質種類較多,有酸、堿、鹽、氧化劑及水蒸氣等,涂料必須具有化學惰性、耐酸堿鹽腐蝕,涂膜應結構致密,防水滲透性好,附著力強、堅韌豐滿.該產品屬于“化學反應性”涂料,分雙組份包裝,甲組份為樹脂、引發劑,乙組份為活性單體、催化劑。

中石油綦南輸氣管線正式接入中石化南川頁巖氣開采區
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,這是中石油與中石化兩家企業,在川渝地區頁巖氣上,首次實現互聯互通。這樣一來,本地生產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入到中石化開采區內。由此,臨近地區的用氣,不再因為管道“繞路”,而出現供氣不足的情況。
據介紹,這是川渝地區在頁巖氣上,第一條實現互聯互通的輸氣管線,它能有效整合中石油、中石化各自的區域管網與產能優勢,整體提升我市管網供氣的靈活性。與此同時,我市產出的頁巖氣新能源,也能更加高效利用,更有效地輸出。
