管線管規(guī)格:10.3-2032×1.7-39.7mm 執(zhí)行標(biāo)準(zhǔn): GB/T9711.1/API SPEC 5L
用途:用于石油、天然氣工業(yè)中的氣、水、油輸送
API SPEC 5L-2011(管線管規(guī)范),是美國石油學(xué)會編制并發(fā)布的,在世界各地通用。 管線管:是把抽出地面的油、氣或水,通過管線管輸送到石油和天然氣工業(yè)企業(yè)。管線管包括無縫和焊接管兩種,其管端有平端、帶螺紋端和承口端;其連接方式為端頭焊接、接箍連接、承插連接等。該管主要材質(zhì)為L245、L290、L360、L418、L480、G.R B、X42、X46、X56、X65、X70、X80、X100等鋼級。[1]
根據(jù)GB/T9711.1管線鋼管性能要求的不同,按其回火溫度的不同,可將回火分為以下幾種:
【一】低溫回火(150-250度)
低溫回火所得組織為回火馬氏體。其目的是在保持淬火鋼的高硬度和高耐磨性的前提下,降低其淬火內(nèi)應(yīng)力和脆性,以免使用時崩裂或過早損壞。它主要用于各種高碳的切削刃具,量具,GB/T9711.1管線鋼管,滾動軸承以及滲碳件等,回火后硬度一般為HRC58-64。
【二】中溫回火(250-500度)
中溫回火所得組織為回火屈氏體。其目的是獲得高的屈服強度,彈性極限和較高的韌性。因此,它主要用于各種GB/T9711.1管線鋼管和熱作模具的處理,回火后硬度一般為HRC35-50。
【三】高溫回火(500-650度)
高溫回火所得組織為回火索氏體。習(xí)慣上將淬火加高溫回火相結(jié)合的熱處理稱為調(diào)質(zhì)處理,其目的是獲得強度,硬度和塑性,韌性都較好的綜合機械性能。因此,廣泛用于汽車,GB/T9711.1管線鋼管,機床等的重要結(jié)構(gòu)零件,如連桿,螺栓,齒輪及軸類。回火后硬度一般為HB200-330。
