環球新聞資訊，9月27日報道：涂塑鋼管，涂塑鋼管母材包括無縫鋼管，螺旋鋼管和直縫鋼管。涂層以其良好的抗腐蝕性、抗水氣滲透性以及力學性能等，在石油管道行業得到了廣泛應用。鋼管一防腐層對于埋地管道的壽命來說是至關重要的，同樣材質的管道，有的埋在地下幾十年不腐蝕，有的幾年就發生泄露。就是因為它們采用了不同的外防腐層。涂塑鋼管具有優良的耐腐蝕性和比較小的摩擦阻力。環氧樹脂涂塑鋼管適用于給排水、海水、溫水、油、氣體等介質的輸送，聚氯乙烯涂塑鋼管適用于排水、海水、油、氣體等介質的輸送。 Global News, September 27: Plastic coated steel pipes, coated steel pipes base material including seamless steel pipes, spiral steel pipes and straight seam steel pipes. Coating has been widely used in petroleum pipeline industry because of its good corrosion resistance, water and gas permeability resistance and mechanical properties. The anticorrosive coating of steel pipe is very important for the life of buried pipeline. Some pipelines of the same material are buried underground for decades without corrosion, and some are leaked in a few years. It is because they use different external anticorrosive coatings. The plastic coated steel pipe has excellent corrosion resistance and relatively small friction resistance. Epoxy resin coated steel pipe is suitable for water supply and drainage, seawater, warm water, oil, gas and other media transmission, PVC coated steel pipe is suitable for drainage, seawater, oil, gas and other media transmission. 涂塑鋼管應用于各種形式的循環水系統（民用循環水、工業循環水），性能優良，防腐年限可達50年,消防供水系統,各建筑的給排水輸送（特別適用于賓館、酒店、高檔住宅區的冷、熱水系統）,各種化工流體輸送（耐酸、堿、鹽的腐蝕）,電線電纜的地埋管、過路管,礦山、礦井的通風管、供、排水管。附著力試驗附著力試驗按中7.4.2進行，試驗結果應符合5.6的規定。彎曲試驗DN≤50mm的涂覆鋼管進行彎曲試驗。管段試件長度為(1200±100) mm。在溫度為（20±5） ℃的環境下，以鋼管公稱通徑的8倍為曲率半徑，彎曲角度為30o，在彎管機或模具上進行彎曲。彎曲試驗時管內不帶填充物，焊縫位于彎曲主面的側面。試驗后，從彎曲圓弧的中部將試件剖開，檢查內涂層，試驗結果應符合5.7的規定。三層結構的聚乙烯(3PE)防腐涂層以其良好的抗腐蝕性、抗水氣滲透性以及力學性能等，在石油管道行業得到了廣泛應用。3PE防腐鋼管一防腐層對于埋地管道的壽命來說是至關重要的，同樣材質的管道，有的埋在地下幾十年不腐蝕，有的幾年就發生泄露。就是因為它們采用了不同的外防腐層。 Plastic coated steel pipes are used in various types of circulating water systems (civil circulating water, industrial circulating water). They have excellent performances and can last up to 50 years for corrosion protection. Fire fighting water supply systems, water supply and drainage systems for various buildings (especially for cold and hot water systems in hotels, hotels and high-grade residential areas), and various chemical fluids (acid, alkali, salt resistance) Corrosion, wire and cable buried pipe, crossing pipe, mine, mine ventilation pipe, supply and drainage pipe. Adhesion test adhesion test carried out according to 7.4.2, the test results should meet the requirements of 5.6. Bending test of DN coated steel pipe with a thickness of less than 50mm is carried out. The length of the pipe specimen is (1200 + 100) mm. In the environment of temperature (20 During bending test, there is no filler in the pipe, and the weld is located on the side of the bending main surface. After the test, the specimen is dissected from the middle of the bending arc to check the inner coating. The test results should meet the requirements of 5.7. Three-layer structure polyethylene (3PE) anticorrosive coating has been widely used in oil pipeline industry because of its good corrosion resistance, water and gas permeability resistance and mechanical properties. The 3PE anticorrosive steel pipe - anticorrosive coating is very important for the life of buried pipelines. Some pipelines of the same material are buried underground for decades without corrosion, and some of them are leaked in a few years. It is because they use different external anticorrosive coatings.
帶有螺紋、法蘭、溝槽連接的涂覆鋼管，規定 。內外涂鋼塑復合管是把普通鋼管經過工藝處理，在鋼管內、外表面涂覆一種特質的環氧樹脂材料而制得的鋼塑復合管道，集鋼材的機械性能于塑料涂層的耐腐蝕性能于一體 。表面處理可以提高涂膜對管子的附著力和涂膜的耐久性 。表面處理一般可分為兩大類，一種是機械處理，包括噴砂噴丸、砂紙打磨、鋼刷子刷等幾種，主要去除管子上的毛刺、鐵銹、棱角等；另一種是化學處理，包括洗滌劑除油、堿除油、鹽處理、酸除銹、化學氧化處理等鋼塑復合管放到溝內，逐段碼成直線進行連接，連接好的管道須找好坡度 。首先說到我們所說的*點就是偽劣鋼管易出現折疊 。涂塑管的工藝標準 |
