是現(xiàn)代試驗硬度常用的方法。常用的試驗法有洛氏硬度試驗洛氏硬度試驗機利用鉆石沖入金屬的深度來測定高壓鍋爐管的硬度, 沖入深度愈大, 硬度愈小。鉆石沖入金屬的深度, 可從指針指出正確的數(shù)字, 該數(shù)字稱為洛氏硬度數(shù)。<br /> 鍛造 - 是用錘擊使金屬成為一定形狀<成型> 的方法, 當高壓鍋爐管加熱達到鍛造溫度時, 可以從事鍛造, 彎屈, 抽拉, 成型等操作。大多數(shù)高壓鍋爐管加熱至鮮明櫻紅色時都很易鍛造。<br /> 脆性 - 表示高壓鍋爐管容易破裂的性質(zhì), 鑄鐵的脆性大, 甚至跌落地上亦會破裂。脆性與硬度有密切關系, 硬度高的20#精密鋼管通常脆性亦大。<br /> 延性 - (又稱柔軟性) 是金屬受外力變形而不碎裂的性質(zhì), 延性的高壓鍋爐管可抽拉成細線。<br /> 彈性 - 是高壓鍋爐管受外力變形, 當外力之後又恢復其原有形狀的一種性質(zhì)。彈簧鋼是極富彈性的一種材料。<br /> 硬度 - 是金屬抵抗外物刺入或切削的一種能增加高壓鍋爐管硬度常用的方法是淬火。<br /> 展性 - 又稱可鍛性, 是金屬延性或柔軟性的另一種表示法。展性是金屬接受錘鍛或滾軋而變形時不致破裂的一種性質(zhì)。<br /> 韌性是高壓鍋爐管抵受震動或沖擊的能力。韌性與脆性剛好相反。</div><p><img

到目前為止，僅僅是以ASTMA333Gr.8和Gr.11鋼管為代表的使用溫度低至-196℃的鐵素體型低溫無縫管成功實現(xiàn)了商業(yè)化，出于考慮，各國對鐵素體型低溫管的生產(chǎn)和使用制定了專門的標準，如EN10216-4和GB/T18984。從用途上看，低溫管主要有低溫管道和低溫熱交換器管，相比于國標和歐標只制定單一標準來說，日本和美國針對用途分別制定了不同的標準，如針對低溫管道的JISG3460和ASTMA333，以及針對低溫換熱器管的JISG3464和ASTMA334。國際上低溫無縫管的生產(chǎn)和驗收多采用美標，國內(nèi)設計也多參照美標，因而按美標生產(chǎn)低溫管是大勢所趨，這不僅有利于適合國內(nèi)采用美標設計需求，實現(xiàn)國產(chǎn)替代，更有利于產(chǎn)品直接出口走向國際市場。 </p> <p> 現(xiàn)實中，隨著石化大型成套裝置國產(chǎn)化水平的持續(xù)提高，尤其是成套裝置的陸續(xù)出口，均需國產(chǎn)化美標低溫管或國標低溫管納入美標的支撐，尤其迫切需要拓展國際低溫無縫管體系。我國鋼鐵裝備和技術(shù)水平的不斷提高也具備國產(chǎn)化美標低溫管的基礎，開展超標極限評估和非標適用性評價，不僅有利于證明國產(chǎn)化美標低溫無縫管的優(yōu)良品質(zhì)，還可探索其極限使用溫度和擴展用途。
