class="khcont5">以ψ表示，單位為%。計算公式如下：式中：S0--試樣原始橫截面積，mm2；S1--試樣拉斷后縮徑處的少橫截面積，mm2。硬度指標(biāo)金屬材料抵抗硬的物體壓陷表面的能力，稱為硬度。根據(jù)試驗方法和適用范圍不同，硬度又可分為布氏硬度、洛氏硬度、維氏硬度、肖氏硬度、顯微硬度和高溫硬度等。對于管材一般常用的有布氏、洛氏、維氏硬度三種。A、布氏硬度（HB）用一定直徑的鋼球或硬質(zhì)合金球，以規(guī)定的試驗力（F）壓入式樣表面，經(jīng)規(guī)定保持時間后卸除試驗力，測量試樣表面的壓痕直徑（L）。布氏硬度值是以試驗力除以壓痕球形表面積所得的商。以HBS（鋼球）表示，單位為N/mm2(MPa)。其計算公式為：式中：F--壓入金屬試樣表面的試驗力，N；D--試驗用鋼球直徑，mm；d--壓痕平均直徑，mm。測定布氏硬度較準(zhǔn)確可靠，但一般HBS只適用于450N/mm2（MPa）以下的金屬材料，對于較硬的鋼或較薄的板材不適用。在鋼管標(biāo)準(zhǔn)中，布氏硬度用途廣，往往以壓痕直徑d來表示該材料的硬度，既直觀，又方便。

class="khcont">4月全國累計生產(chǎn)無縫管875萬噸。焊管產(chǎn)量較去年同期也有所上漲。鋼材整體產(chǎn)量較去年同期上漲。在出口產(chǎn)品中，逾40%為油田專用管，38%為線管、18%為鍋爐管。今年前5個月，我國無縫管出口量增長28%至176萬噸，部分市場人士預(yù)計今年出口總量將達到400萬噸。目前，印度已經(jīng)取代美國成為我國無縫管頭號出口目的國。受貿(mào)易訴訟的影響，美國和歐洲自2009年起甚至連中國的前十大出口目的國榜單也不入。近來由于政治動亂，部分中東和北非在我國的采購量也有所下降，因而在榜單上的名次也有所滑落。 2016年的前5個月，我國無縫管進口量為109117噸，同比增長4%。近年來，經(jīng)過產(chǎn)業(yè)升級，我國95%的產(chǎn)品需求都可以實現(xiàn)自給，進口的無縫管也多為高價值的特級鍋爐管和油井管。當(dāng)前，無縫管業(yè)產(chǎn)能過剩嚴(yán)重，產(chǎn)能利用率低下，惡性競爭加劇，鋼材價格持續(xù)下行，無縫管企業(yè)效益大幅下降，減產(chǎn)停產(chǎn)企業(yè)持續(xù)增多，企業(yè)風(fēng)險在加速集聚。產(chǎn)能過剩對于無縫管行業(yè)的發(fā)展產(chǎn)生持續(xù)的阻力，去產(chǎn)能和供給側(cè)改革成為無縫管行業(yè)主基調(diào)。

class="khcont">實彎的優(yōu)點是反彈小，成型準(zhǔn)確，而且只要輥型準(zhǔn)確，內(nèi)角成型的R比較準(zhǔn)確?？諒澋膬?yōu)點是可以在無法進行實彎時進行邊長的彎折，比如方矩管的上邊/側(cè)邊同步彎折和精整?？諒澾€可以彎折R<0.2t的內(nèi)角而不致管壁發(fā)生斷裂。焊管發(fā)展方向問題的再認(rèn)識但從前面敘述的焊管取代無縫管的論述來講，也只能夠是直縫焊管挑大梁而不是螺旋焊管，這就是西方為什么要大力發(fā)展直縫焊管的原因所在，也是咱們公司之所以選擇直縫焊管的原因所在。無縫鋼管“西氣東輸”工程的實踐已經(jīng)從一個側(cè)面說明螺旋焊管可以用于輸送天然氣(一類地區(qū))；但螺旋焊管的生產(chǎn)工藝要適應(yīng)成批、穩(wěn)定地生產(chǎn)大口徑（l000mm以上)、高鋼級(X70級以上)、厚厚(14mm以上)是頗為艱難的。例如，西氣東輸鋼管技術(shù)標(biāo)準(zhǔn)要求錯邊量小于2mm，由此，要求帶鋼的月牙彎必須小于8mm/5m，但標(biāo)準(zhǔn)和國內(nèi)標(biāo)準(zhǔn)GS/714164-93規(guī)定帶鋼的月牙彎為25mm/m，很難滿足這個要求。無縫鋼管這就是加拿大為什么用鋼板而不用鋼卷來制作螺旋管的原因。何況螺旋焊管用機械擴徑方法來應(yīng)力難度大，外防腐層厚度在螺旋焊縫處的厚度比管體上的要減薄近30％，這些都不能不列入工程考慮范圍之內(nèi)。制管全過程是一個系統(tǒng)工程，不僅僅限于學(xué)術(shù)研究上討論管體力學(xué)分析，不能避開管型制作工藝流程、應(yīng)力方法、無損檢測方式以及防腐效果諸多問題。
