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(yīng)用于各種形式的循環(huán)水系統(tǒng)（民用循環(huán)水、工業(yè)循環(huán)水），性能優(yōu)良，防腐年限可達(dá)50年,消防供水系統(tǒng),各建筑的給排水輸送（特別適用于賓館、酒店、高檔住宅區(qū)的冷、熱水系統(tǒng)）,各種化工流體輸送（耐酸、堿、鹽的腐蝕）,電線電纜的地埋管、過(guò)路管,礦山、礦井的通風(fēng)管、供、排水管。附著力試驗(yàn)附著力試驗(yàn)按中7.4.2進(jìn)行，試驗(yàn)結(jié)果應(yīng)符合5.6的規(guī)定。彎曲試驗(yàn)DN≤50mm的涂覆鋼管進(jìn)行彎曲試驗(yàn)。管段試件長(zhǎng)度為(1200±100) mm。在溫度為（20±5） ℃的環(huán)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(jī)或模具上進(jìn)行彎曲。彎曲試驗(yàn)時(shí)管內(nèi)不帶填充物，焊縫位于彎曲主面的側(cè)面。試驗(yàn)后，從彎曲圓弧的中部將試件剖開(kāi)，檢查內(nèi)涂層，試驗(yàn)結(jié)果應(yīng)符合5.7的規(guī)定。三層結(jié)構(gòu)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(xué)性能等，在石油管道行業(yè)得到了廣泛應(yīng)用。3PE防腐鋼管一防腐層對(duì)于埋地管道的壽命來(lái)說(shuō)是至關(guān)重要的，同樣材質(zhì)的管道，有的埋在地下幾十年不腐蝕，有的幾年就發(fā)生泄露。就是因?yàn)樗鼈儾捎昧瞬煌耐夥栏瘜印?/span> 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(guī)定 。內(nèi)外涂鋼塑復(fù)合管是把普通鋼管經(jīng)過(guò)工藝處理，在鋼管內(nèi)、外表面涂覆一種特質(zhì)的環(huán)氧樹(shù)脂材料而制得的鋼塑復(fù)合管道，集鋼材的機(jī)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(duì)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(jī)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(xué)處理，包括洗滌劑除油、堿除油、鹽處理、酸除銹、化學(xué)氧化處理等鋼塑復(fù)合管放到溝內(nèi)，逐段碼成直線進(jìn)行連接，連接好的管道須找好坡度 。首先說(shuō)到我們所說(shuō)的*點(diǎn)就是偽劣鋼管易出現(xiàn)折疊 。涂塑管的工藝標(biāo)準(zhǔn) |
