鍍鋅鋼管，分熱鍍鋅和冷鍍鋅兩種，熱鍍鋅鍍鋅層厚，具有鍍層均勻，附著力強(qiáng)，使用壽命長(zhǎng)等優(yōu)點(diǎn)。冷鍍鋅成本低，表面不是很光滑，其本身的耐腐蝕性比熱鍍鋅管差很多。熱鍍鋅管是使熔融金屬與鐵基體反應(yīng)而產(chǎn)生合金層，從而使基體和鍍層二者相結(jié)合。熱鍍鋅是先將鋼管進(jìn)行酸洗，為了去除鋼管表面的氧化鐵，酸洗后，通過(guò)氯化銨或氯化鋅水溶液或氯化銨和氯化鋅混合水溶液槽中進(jìn)行清洗，然后送入熱浸鍍槽中。熱鍍鋅具有鍍層均勻，附著力強(qiáng)，使用壽命長(zhǎng)等優(yōu)點(diǎn)。北方大部分工藝采用鍍鋅帶直接卷管補(bǔ)鋅工藝。熱鍍鋅具有鍍層均勻，附著力強(qiáng)，使用壽命長(zhǎng)等優(yōu)點(diǎn)。熱鍍鋅鋼管基體與熔融的鍍液發(fā)生復(fù)雜的物理、化學(xué)反應(yīng)，形成耐腐蝕的結(jié)構(gòu)緊密的鋅一鐵合金層。合金層與純鋅層、鋼管基體融為一體。故其耐腐蝕能力強(qiáng)。冷鍍鋅管冷鍍鋅就是電鍍鋅，鍍鋅量少，只有10－50g/m2，其本身的耐腐蝕性比熱鍍鋅管差很多。鍍鋅管的用途很廣，除作輸水、煤氣、油等一般低壓力流體的管線(xiàn)管外，還用作石油工業(yè)特別是海洋油田的油井管、輸油管，化工焦化設(shè)備的油加熱器、冷凝冷卻器、煤餾洗油交換器用管，以及棧橋管樁、礦山坑道的支撐架用管等。懷遠(yuǎn)鍍鋅鋼管便宜將橡膠密封圈套在另一根鋼管頂端，使橡膠密封圈位于接口中間部位，并在其周邊涂抹潤(rùn)滑劑。</p><div

涂塑鋼管，又名涂塑管、鋼塑復(fù)合管、涂塑復(fù)合鋼管，是以鋼管為基體，通過(guò)噴、滾、浸、吸工藝在鋼管（底管）內(nèi)表面熔接一層塑料防腐層或在內(nèi)外表面熔接塑料防腐層的鋼塑復(fù)合鋼管。涂塑鋼管具有優(yōu)良的耐腐蝕性和比較小的阻力。環(huán)氧樹(shù)脂涂塑鋼管適用于給排水、海水、溫水、油、氣體等介質(zhì)的輸送，聚氯涂塑鋼管適用于排水、海水、油、氣體等介質(zhì)的輸送。涂塑鋼管是國(guó)內(nèi)新發(fā)展的一種新型管道材料，采用內(nèi)外均有涂塑保護(hù)層，中間為增強(qiáng)焊接鋼管或無(wú)縫承壓鋼管的復(fù)合結(jié)構(gòu)，克服了鋼管本身存在的易生銹、腐蝕、高污染、及塑料管強(qiáng)度低、易變形的缺點(diǎn)，整合了鋼管和塑料產(chǎn)品的共同優(yōu)點(diǎn)，屬于推廣使用的環(huán)保產(chǎn)品。涂塑復(fù)合鋼管是在鋼管融溶一層厚度為~的聚(PE)樹(shù)脂、-共聚物(EAA)、環(huán)氧(EP)粉末、聚丙烯(PP)或聚氯(PVC)等有機(jī)物而構(gòu)成的鋼塑復(fù)合型管材，它不但具有鋼管的度、易連接、耐水流沖擊等優(yōu)點(diǎn)，還克服了鋼管遇水易腐蝕、污染、結(jié)垢及塑料管強(qiáng)度不高、消防性能差等缺點(diǎn)，設(shè)計(jì)壽命可達(dá)50年。主要缺點(diǎn)是安裝時(shí)不得進(jìn)行彎曲，熱加工和電焊切割等作業(yè)時(shí)，切割面應(yīng)用生產(chǎn)廠(chǎng)家配有的常溫固化膠涂刷。主要規(guī)格有DN15-DN300。提出**治理基礎(chǔ)制度，建立覆蓋所有固定污染源。</p><p>
