不銹鋼圓管是一種中空的長條圓形鋼材，主要用于石油、化工、醫(yī)療、食品、輕工、機(jī)械儀表等工業(yè)輸送管道以及機(jī)械結(jié)構(gòu)部件等。另外，在折彎、抗扭強(qiáng)度相同時(shí)，重量較輕，所以也用于制造機(jī)械零件和工程結(jié)構(gòu)。也常用作生產(chǎn)各種常規(guī)武器、管、炮彈等。中文名不銹鋼圓管外文名Stainlesssteelroundtube應(yīng)用范圍石油、化工、醫(yī)療、食品、輕工等材質(zhì)金屬形狀管狀目錄1分類2生銹現(xiàn)象原因不銹鋼圓管分類編輯此類鋼管可以分為不銹鋼無縫鋼管和不銹鋼焊接鋼管（有縫管）兩大類。按照制造工藝的不同可以為：熱軋、擠壓、冷拔和冷軋這幾種基本類型，按斷面形狀又可分為圓管和異形管，應(yīng)用的是圓形鋼管，但也有一些方形、矩形、半圓形、六角形、等邊三角形、八角形等異形不銹鋼鋼管。對于承受流體壓力的鋼管都要進(jìn)行液壓試驗(yàn)來檢驗(yàn)其耐壓能力和質(zhì)量，在規(guī)定的壓力下不發(fā)生泄漏、浸濕或膨脹為合格，有些鋼管還要根據(jù)標(biāo)準(zhǔn)或需方要求進(jìn)行卷邊試驗(yàn)、擴(kuò)口試驗(yàn)、壓扁試驗(yàn)。無縫不銹鋼圓管也稱不銹鋼無縫管，是用鋼錠或?qū)嵭墓芘鹘?jīng)穿孔制成毛管，然后經(jīng)熱軋、冷軋或冷撥制成。</p><p> 一般的無縫鋼管的生產(chǎn)工藝可以分為冷拔與熱軋兩種，冷軋無縫鋼管的生產(chǎn)流程一般要比熱軋要復(fù)雜，管坯首先要進(jìn)行三輥連軋，擠壓后要進(jìn)行定徑測試，如果表面沒有響應(yīng)裂紋后圓管要經(jīng)過割機(jī)進(jìn)行切割，切割成長度約一米的坯料。然后進(jìn)入退火流程，退火要用酸性液體進(jìn)行酸洗，酸洗時(shí)要注意表面是否有大量的起泡產(chǎn)生，如果有大量的起泡產(chǎn)生說明鋼管的質(zhì)量達(dá)不到相應(yīng)的標(biāo)準(zhǔn)。外觀上冷軋無縫鋼管要短于熱軋無縫鋼管，冷軋無縫鋼管的壁厚一般比熱軋無縫鋼管要小，但是表面看起來比厚壁無縫鋼管更加明亮，表面沒有太多的粗糙，口徑也沒有太多的毛刺。熱軋無縫鋼管的交貨狀態(tài)一般是熱軋狀態(tài)經(jīng)過熱處理后進(jìn)行交貨。熱軋無縫鋼管在經(jīng)過質(zhì)檢后要經(jīng)過工作人員的嚴(yán)格的手工挑選，在質(zhì)檢后要進(jìn)行表面涂油，然后緊接著是多次的冷拔實(shí)驗(yàn)，熱軋?zhí)幚砗笠M(jìn)行穿孔的實(shí)驗(yàn)，如果穿孔擴(kuò)徑過大就要進(jìn)行矯直矯正。
