從技術(shù)方面來看，無縫異型鋼管行業(yè)在調(diào)整產(chǎn)品結(jié)構(gòu)上有了長足的進步，2014年高附加值、高技術(shù)含量產(chǎn)品增長較快。從無縫管領(lǐng)域來看，石油專用管、高壓鍋爐管、氣瓶、無縫異型鋼管液壓支護管產(chǎn)量都有較大程度提高;從焊管領(lǐng)域來看，管線管、J55級表層石油套管、中低壓鍋爐焊管、高強度耐候建筑結(jié)構(gòu)焊管、汽車傳動軸管、鋼塑復(fù)合管以及大口徑方矩形管、精密異型焊管、氣動液壓焊管等都有較大程度的提高或開發(fā)，因而體現(xiàn)在經(jīng)濟效益好轉(zhuǎn)。盡管上游原料價格上漲幅度較大，但異型鋼管各企業(yè)在適應(yīng)市場變化、調(diào)整產(chǎn)品結(jié)構(gòu)和對標(biāo)挖潛方面做了大量的工作，使鋼管市場價格比較穩(wěn)定，企業(yè)效益仍然上升。

From the technical point of view, the seamless special-shaped steel pipe industry has made considerable progress in adjusting the product structure. In 2014, the products with high added value and high technology content grew rapidly. In the field of seamless pipe, the output of special oil pipe, high pressure boiler pipe, gas cylinder and seamless special-shaped steel pipe hydraulic support pipe has been greatly increased; in the field of welded pipe, pipeline pipe, J55 surface oil pipe, welded pipe of medium and low pressure boiler, welded pipe of high strength weatherproof building structure, automobile transmission axle pipe, steel-plastic composite pipe and large caliber square rectangular pipe, precision special-shaped welded pipe, gas pipe. Hydraulic welded pipes and so on have been greatly improved or developed, which is reflected in the improvement of economic benefits. Although the price of raw materials in the upstream has risen considerably, a lot of work has been done by the special-shaped steel pipe enterprises in adapting to market changes, adjusting product structure and tapping potential for tenders, so that the market price of steel pipe is relatively stable and the benefits of enterprises are still rising. 我國無縫異型鋼管行業(yè)生產(chǎn)技術(shù)裝備水平既有世界頂尖的無縫鋼管和焊接鋼管生產(chǎn)機組，無縫異型鋼管又有不斷增加的穿孔+冷拔機組和焊接鋼管熱鍍鋅機組等。異型鋼管后者生產(chǎn)過程涉及到廢酸、廢水的處理和廢氣排放等問題，這些機組大部分裝備水平很低，環(huán)保設(shè)施不完善。無縫異型管初步統(tǒng)計數(shù)據(jù)顯示，穿孔+冷拔機組占我國無縫鋼管機組總數(shù)的比例達60%左右，產(chǎn)量占20%左右，熱鍍鋅機組也占有一定的比例。這些機組中相當(dāng)一部分是屬于須淘汰或改造的產(chǎn)能。

The production technology and equipment level of China's seamless special-shaped steel pipe industry includes the world's top seamless steel pipe and welded steel pipe production units, seamless special-shaped steel pipe production units and the increasing number of perforation+cold drawing units and hot-dip galvanizing units for welded steel pipes. The latter involves waste acid, waste water treatment and exhaust gas discharge. Most of these units have low equipment level and imperfect environmental protection facilities. Preliminary statistical data of seamless special-shaped tubes show that the proportion of perforation and cold drawing units to the total number of seamless steel tube units in China is about 60%, the output is about 20%, and the hot-dip galvanizing units also account for a certain proportion. A considerable part of these units belong to the capacity that needs to be eliminated or revamped.
