答:管道分類辦法通常按介質(zhì)的壓力、溫度、性質(zhì)分類,也可按管道材質(zhì)、溫度和壓力分類,以及材質(zhì)狀況等分類辦法。
這里管道按其材質(zhì)可分為鋼管、有色金屬管、鑄鐵管、非金屬管四種。他們的主要用處例舉如下:
(1)鋼管
1)普通無(wú)縫鋼管、用于制造流體介質(zhì)管道或制造構(gòu)造管件等。規(guī)范為 GB/T 8163—1999《保送流體用無(wú)縫鋼管》。常用規(guī)格:構(gòu)造用無(wú)縫鋼管外徑 5~200,壁厚 0.25~14mm,見表 2-1;保送流體用無(wú)縫鋼管外徑 32~630mm。壁厚 2.5~75mm,見表 2-2。
常用無(wú)縫鋼管規(guī)格尺寸及單位長(zhǎng)度理論質(zhì)量(kg/m)見表 2-3。

焊接鋼管用于石油和自然氣長(zhǎng)間隔保送管道較多。我國(guó)出口的鋼管中焊接鋼管比無(wú)縫鋼管多,近年來,美國(guó)進(jìn)口焊接鋼管 1/3 是中國(guó)產(chǎn)品。
(2)有色金屬管
1)銅及銅合金管:管道工程用銅管管材有純銅管(工業(yè)純銅)、黃銅管(銅鋅合金與特殊黃銅)和青銅管(鋁青銅和錫青銅等)。按制造辦法,銅管又可分為拉制管、軋制管和擠制管等,普通中、低壓管道采用拉制管。純銅管和黃銅管大多用于制造換熱設(shè)備、制冷系統(tǒng)、化工管路、以及儀表的測(cè)壓管線或傳送液體的管線上。
純銅管適用于工作壓力在 4MPa 一下、溫度為 -196~250℃ 的管路、黃銅管適用于工作壓力在 22MPa 以下、溫度為 -158~120℃ 的管路。在制冷系統(tǒng)中,銅管適用于工作壓力低于 2MPa、溫度為 -20~150℃,保送制冷劑與光滑油的管路上,近年來已用在室內(nèi)燃?xì)夤苈芳案呒?jí)賓館的冷熱水系統(tǒng)上。
2)鋁及鋁合金管:鋁及鋁合金管只需用于保送脂肪酸、硫化氫、二氧化碳和硝酸、醋酸等管道。它普通采用拉制和擠壓等辦法消費(fèi);其有質(zhì)量輕、不銹蝕等特性,但其機(jī)械強(qiáng)度較差,不能接受較高壓力。
3)鈦管:鈦管常用于其他管材無(wú)法勝任的工藝部位,其主要特性是質(zhì)量輕、強(qiáng)度高、耐腐蝕、耐低溫,適用溫度范圍為 -140~250℃,當(dāng)溫度高于 250℃ 時(shí),其力學(xué)性能降落。
(3)鑄鐵管
1)高硅鑄鐵管:高硅管道是由含碳量在 0.5%~1.2%(質(zhì)量分?jǐn)?shù),下同),含硅量在 10%~17% 的鐵硅合金組成,具有很高的耐腐蝕性能。常用的高硅鑄鐵含硅量為 14.5%,隨著硅含量的增加,耐腐蝕性能增大,但脆性也變大。普通運(yùn)用壓力為 0.25MPa 以下。
2)普通鑄鐵管:普通承插鑄鐵管用于給排水管道,按壓力不同分為低壓管(<0.45MPa)、中壓管(0.45~0.75MPa)和高壓管(0.75~1.0MPa),將管與法蘭鑄成一體的普通法蘭鑄鐵管拆卸便當(dāng),應(yīng)用較普遍。
(4)非金屬管
1)耐酸酚醛塑料管:耐酸酚醛塑料管具有良好的耐腐蝕性能,能抗大局部酸性、有機(jī)溶劑等腐蝕,但不耐堿性及強(qiáng)氧化性的酸腐蝕。由于其沖擊韌性差,較脆,故不宜在有機(jī)械振動(dòng)、溫度變化大的狀況下運(yùn)用,普通用于溫度為 -30~130℃、壓力 <0.6MPa 的工況。
2)硬聚氯乙烯管:硬聚氯乙烯管對(duì)不同濃度的大局部酸堿鹽類的溶液有較好的耐腐蝕性,但在 50%以上的硝酸及發(fā)煙硫酸中則不穩(wěn)定。其傳熱系數(shù)低、塑性好,不過其強(qiáng)度差,且只要在 60℃ 以下時(shí)才干堅(jiān)持恰當(dāng)強(qiáng)度,用于壓力 <0.6MPa 的工況。
3)石墨管:石墨管具有良好的耐腐蝕性,且熱脹系數(shù)小,不污染介質(zhì),但其較脆,強(qiáng)度低,適用于溫度 <150℃、壓力 <0.3MPa 的工況。
4)耐酸陶瓷管:耐酸陶瓷管具有良好的耐腐蝕性、不浸透性。但它耐溫度驟變性差、強(qiáng)度差、強(qiáng)度低、不宜用于劇毒或易燃易爆介質(zhì),普通用于溫度 <120℃、壓力為常壓的工況。
5)玻璃管:玻璃管對(duì)除氫氟酸外的酸類、稀堿及有機(jī)溶劑等具有良好的耐蝕性,但其抗拉強(qiáng)度低、常用于溫度 <120℃、壓力 <2.0MPa 的工況。
6)混凝土管:混凝土管分為預(yù)應(yīng)力和自應(yīng)力鋼筋混凝土管兩種。管口銜接采用承插接口,用圓形截面的橡膠圈密封,適用于長(zhǎng)間隔保送低壓水、氣等,普通用于壓力 <1.0MPa 的工況。
普通無(wú)縫鋼管由 10、20、Q295、Q345 牌號(hào)的鋼制造。按制造辦法分為熱軋無(wú)縫鋼管和冷拔(軋)無(wú)縫管,熱軋鋼管的長(zhǎng)度為 3000~12000mm。冷拔鋼管的長(zhǎng)度為 3000~10500mm。保送流體用無(wú)縫鋼管,常用規(guī)格見表 2-3。
