class="khcont8">碳鋼管通常采用退火處理，而不銹鋼則采用固溶處理。幾何無縫化—內(nèi)外毛刺技術(shù)通常一個完整的內(nèi)毛刺系統(tǒng)由刀具、支持系統(tǒng)和調(diào)控系統(tǒng)三個部份組成，其技術(shù)關(guān)鍵在于刀具的形狀和壽命。內(nèi)毛刺的余高一般控制在0.2mm以內(nèi)，甚至0.1mm以內(nèi)。外毛刺技術(shù)較為簡單，于管體外裝外毛刺刮刀即可。物理無縫化—焊縫退火處理在高頻焊接過程中，由于趨膚效應(yīng)、臨近效應(yīng)和熱傳導(dǎo)的綜合作用，造成了管坯邊緣附近的溫度分布梯度，形成了熔化區(qū)、部分熔化區(qū)、過熱組織區(qū)、正火區(qū)、不完全正火區(qū)、回火區(qū)等特征區(qū)域。其中過熱區(qū)組織由于焊接的溫度在1100℃以上，奧氏體晶粒急劇長大，冷卻后晶粒粗大，在一定的化學(xué)成分和冷速條件下還會形成硬而脆的晶相。此外，由于溫度梯度的存在也會產(chǎn)生焊接應(yīng)力。其綜合結(jié)果，焊縫區(qū)的綜合機(jī)械性能比母材低。焊管物理無縫化就是通過焊縫熱處理，達(dá)到應(yīng)力、均化和細(xì)化組織、提高焊接熱影響區(qū)綜合機(jī)械性能的目的，而其根本目的是應(yīng)力。直縫電阻焊鋼管與流體輸送用無縫鋼管相比具有相當(dāng)?shù)募夹g(shù)優(yōu)勢，例如焊管壁厚較薄，尺寸精度較高，等等。

class="khcont">焊接鋼管目前根據(jù)焊縫形式不同分為直縫焊接鋼管、螺旋焊接鋼管兩種，直縫焊接鋼管就焊接工藝不同又分為直縫電阻焊鋼管（ERW）和直縫埋弧焊鋼管（LSAW），執(zhí)行標(biāo)準(zhǔn)為《低壓流體輸送用焊接鋼管》(GB/T3091-2001)，焊接鋼管均是利用軋輥等模具將帶鋼延圓形漸開線逐步卷為圓形，再通過埋弧、電阻等不同焊接方式焊接成型生產(chǎn)的鋼管。該成型方式的特點(diǎn)是產(chǎn)品產(chǎn)量高、成本低、耗能小、長度可以達(dá)16米且可以定尺、直徑及壁厚可良好控制，缺點(diǎn)主要是目前國內(nèi)鋼管生產(chǎn)設(shè)備技術(shù)落后，導(dǎo)致焊縫部分強(qiáng)度不足，壁厚一般國內(nèi)無法做厚。目前可以承接美國ASTMA5德國DIN、日本JIS、美國石油學(xué)會APISpec5L等各種標(biāo)準(zhǔn)的焊接鋼管，熱擴(kuò)鋼管是指鋼管中頻加熱后利用模具擴(kuò)徑生產(chǎn)的鋼管，該成形方式母材既可用無縫鋼管，也可用焊接鋼管（需要除去內(nèi)焊縫），特點(diǎn)為母材靈活、產(chǎn)量高、耗能大、成本低。[］目前還沒有熱擴(kuò)鋼管相關(guān)標(biāo)準(zhǔn)，一般執(zhí)行GB/T8163-1999標(biāo)準(zhǔn)。本公司擁有2套熱擴(kuò)生產(chǎn)線，一條為219-325mm生產(chǎn)線，一條為325-630生產(chǎn)線。
