由表 1-2 可知,五年來,鋼管產量和表觀消費量平均以 22.46% 和 19.77% 的幅度高速增長。2003 年以后,鋼管自給率逐漸呈供大于求的局面,即自給率大于百分之百進口管。中國鋼鐵工業協會指出:管材在鋼材表觀消費總量中的比例,2000 年為 6.61%,2005 年為 6.42%,變化不大。其中,無縫鋼管由 2000 年的凈出口 3×104t,轉為 2005 年凈出口 71.4×104t;焊接鋼管由 2000 年的凈出口 3×104t,轉為 2005 年凈出口 124.5×104苹果彩票app下载t。管材在國內市場的國產化率已達 95.5%。

十一五期間規劃經濟發展的態勢是又好又快,其著力點是創新、節能和環保。至于 GDP 增長率,十一五前兩年(2006 年和 2007年)預計分別是 10.7% 和 8%。平均為 9% 左右。預計后三年可能是 7.5%~8%。十一五期間 GDP 增長率平均約為 8%。中國鋼鐵協會預測 2010 年我國粗鋼消費達到 4.9×108t,鋼材消費達到 4.7×108t。這個預測是在總結十五期間預測的經驗教訓基礎上得出的。

2)十一五期間鋼管市場的需求評價:十一五期間,中國能源需求強勁是中國鋼管行業發展的直接動力。預測 2010 年將消費(25~33)×108t 標煤,十一五期間能源建設將投資 3.5 萬億元。到 2020 年,我國能源工業累計投資將達到 10 萬億元,從 2005 年起,每年投資 7000 多億元。其中 2020 年煤炭生產能力將達到 28×108t,年均投資 700 億元;2010年石油產量將達到 1.8×108t,年均投資 500 億元;2010 年天然氣產量達到 1100×108m³,年均投資 300 億元;2010 年電力裝機,包括火電、水電、喝點、天然氣發電、風電等新能源發電達到 7×108Kw,年均投資 5000 多億元。

①煤炭用鋼管。煤炭用鋼管的數量比較大,用途也比較廣。按鋼管占 20% 來估計,支護用鋼管 2006~2010 年共用 990×104t;礦用帶式輸送機拖輥等設備和排水、通風用鋼管 130×104t。由此可見,煤炭用鋼管共計約 1120×104t。

2006~2010 年共計需油井管 1800×104t。石油行業十一五期間油井管和管線鋼管用量之和約 3800×104t。

③化工用鋼管。十一五期間無縫鋼管、焊管等共計 900×104t。

④電力用鋼管,包括火電用鋼管(蒸汽管、高壓給水管等)、核電用管(傳熱管)、水電用鋼管(焊接鋼管、壓力管)、風電用鋼管(焊管)、電網用鋼管(輸電塔一般用角鋼改為用焊管)。以上電力用鋼管 2006~2010 年總計需求量 575×104t。

⑤鋼結構用鋼管。鋼結構的發展同城市化有密切的關系。華東、中南仍是我國鋼結構消費的主要區域,西北、西南地區的消費比重呈增長勢頭。十一五期間,中國城鎮化率將由 2005 年的 43%,上升到 2010 年的 47%,農村人口轉移到城鎮約 8545×104 人,年需建筑用鋼約 2655×104t。其中,東南部 844×104t,中部 1046×104t,西部 765×104t。五年共需建筑用鋼材約 1.3275×108t。

國內一般以上的鋼材用于建筑行業,推算出 2006~2010 年,鋼結構用鋼管需要 600~700×104t。

⑥房地產用鋼管。房地產用鋼管包括三個方面:一是鋼結構,見⑤中分析;二是城市地下給排水、熱力、通風管道;三是住宅用來水鍍鋅鋼管。十一五期間城市地下水及熱力管網,年需鋼管平均約為 50×104t;地面房屋用鍍鋅鋼管平均約需 800×104t;十一五期間房地產用鋼管量約 4250×104t。

⑦汽車工業用鋼管。2005 年我國汽車產量為 500×104 輛,2006 年達到 650×104 輛,2007 年可達 850×104 輛,2010 年將超過 900×104 輛。關于汽車用剛量的評估,按 2005 年汽車用鋼管 24×104t(其中無縫管 16.91×104t,焊管 7.09×104t)來推算,十一五期間汽車用鋼管量約 160×104t。

⑧造船工業用鋼管。目前世界造船市場處于發展的高峰期。在世界海運貿易增長的推動下,尤其是在中國,石油、礦石進口持續快速增長和集裝箱貨運增速上升的推動下,2005 年我國制船行業產量突破 1222×104t 載重噸,同比增長 41.86%,占世界產量的 18.2%,2006 年造船產量為 1500×104t 載重噸,用鋼材 600×104t,其中管材占 7%,約為 42×104t。2006~2010 年我國造船達到每年平均 830×104t 載重噸,總計為 4152×104t 載重噸。按 2006 年船用鋼管量為基數,推算十一五期間我國造船工業用鋼管量為 250×104t。

⑨集裝箱行業用鋼管。我國集裝箱行業在產銷上已連續 14 年居世界第 1 位,生產集裝箱所用鋼材為耐候鋼,主要有熱軋薄板(1.6~6.0mm)、型鋼和焊管。預計 十一五期間集裝箱需求焊管將達 105×104t。

據不完全統計,機械行業 2004 年消耗鋼材 4500×104t,2005 年消耗鋼材 5200×104t。2006 年機械工業產銷同比增長 15%,由此,預測十一五期間機械工業用鋼量為 2200×104t 左右。

機械制造業用管以大中直徑、中厚壁碳結鋼和低合金鋼管、無縫鋼管為主。用無縫鋼管代替實心段坯制造缸、筒、軸、輥、滾筒、軸承、管模等中空體和結構體,可節約鋼材 20%~30%。又如壓力容器、高壓氣瓶年需無縫鋼管約 10×104t。機械用管中,大中直徑無縫鋼管約占 30%。近幾年,年消耗無縫鋼管(150~160)×104t,約占無縫鋼管消費的 15%。美國的機械結構管消費比例,1997 年為 29.4%,2002 年保持在 24%。隨著我國機械裝備業的發展,我國鋼管用于機械結構管的比例還會增加,將達到 20% 左右。

輕工業用鋼管涉及自行車、影劇院、體育場館、會議廳設備(座椅等)、健身器材、家電、家具、醫療機械、小五金、旅游用品等。2005 年自行車用鋼材 185×104t,其中焊管約 110×104t,由此,預測十一五期間輕工業用鋼管約 880×104t。

⑫鐵路(車輛)用鋼管。十一五期間將加大綜合交通運輸體系投資力度投資總額 65219 億元增長 18.6%。盡管如此,與國際交通運輸發達國家相比,仍由較大差距。從路網密度來看,美國每萬平方千米國土面積就有鐵路 200km,印度有 211km。我國 2005 年年底全國鐵路總營業里程為 7.5×104km,每萬平方千米地面積鐵路僅為 78.11km。

十一五期間國家將繼續加大鐵路網建設,將重新線 1.7×104km,相當于八五、九五和十五總和的 1.3 倍。鐵路車輛由于主要干線提速,需要新購機車 7300 臺,到 2010 年需新購貨車 22×104 輛,新購客車 2.6×104 輛。因此,未來幾年的鐵路車輛用鋼市場潛力巨大。

火車車廂用鋼管主要包括三個方面:一是車廂鋼結構件,例如用方矩形鋼管制作箱梁;二是配管;三是為了提速、減重和安全,用鍛軋的空心軸代替實心軸。目前年需低和金鋼車軸(15~20)×104t。

綜上所述,十一五期間鐵路(車輛)用鋼管約 200×104t。

⑬港口建設用鋼管。我國鋼鐵工業正在向沿海地區發展,如鞍鋼、首鋼、唐鋼在沿海地區建設鋼鐵鋼鐵大廠,配套的港口建設正在發展之中。港口建設和跨海大橋都需要大量打樁用鋼管。例如,杭州灣跨海大橋用的打樁規格為 ø1016mm×16mm,管長 72m,鋼管用量很客觀。螺旋焊管用于樁管較合適,一部分直縫埋弧焊管也可用于樁管。同時,鐵路建設中橋梁也很多,以京滬高速鐵路為例,就有 11 座特大橋需要大量打樁用管。預計十一五期間港頭、碼頭、橋梁需要用作樁管的鋼管月 250×104t。

十一五期間我國鋼管出口量預計約 3000×104t。

(2)工作壓力:管子和管路附近在正常運行條件下所承受的壓力用符號 p 表 示,這個運行條件必須是指某一操作溫度,因而說明某制品的壓力工作應注明其工作溫度,通常是在 p 的下角附加數字,該數字是最高工作溫度除 10 所得的正式整數值,如介質的最高強度為 300℃,工作壓力為 10MPa,則記為 p3010MPa。

(3)試驗壓力:管道與管路附件在出廠前,必須進行壓力試驗,檢查其強度和密封性,對制品進行強度試驗的壓力稱為強度試驗壓力,用符號 ps 表示,如試驗壓力為 4MPa,記為 ps4MPa。從安全角度考慮,試驗壓力必須大于公稱壓力。
