不銹鋼管是一種中空的長(zhǎng)條鋼材，大量用作輸送流體的管道，如石油、天燃?xì)狻⑺⒚簹狻⒄魵獾龋硗猓诟銖潯⒖古?qiáng)度相同時(shí)，重量較輕，所以也廣泛用于制造機(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、槍管、炮彈等。</span></div> <div align="left"><span

align="left"><span style="font-size: 14px">不銹鋼管的應(yīng)用 </span></div> <div align="left"><span style="font-size: 14px">　　隨著我國(guó)改革開(kāi)放政策的實(shí)施，國(guó)民經(jīng)濟(jì)獲得快速增長(zhǎng)，城鎮(zhèn)住宅、公共建筑和旅游設(shè)施大量興建，對(duì)熱水供應(yīng)和生活用水供給提出了新的要求。特別是水質(zhì)問(wèn)題，人們?cè)絹?lái)越重視，要求也不斷提高。鍍鋅鋼管這一常用管材因其易腐蝕性，在國(guó)家相關(guān)政策的影響下，將逐漸退出歷史舞臺(tái)，塑料管、復(fù)合管及銅管成了管道系統(tǒng)的常用管材。但在許多情況下，不銹鋼管更有優(yōu)越性，特別是壁厚僅為0.6～1.2mm的薄壁不銹鋼管在上等飲用水系統(tǒng)、熱水系統(tǒng)及將**、衛(wèi)生放在首位的給水系統(tǒng)，具有**可靠、衛(wèi)生環(huán)保、經(jīng)濟(jì)適用等特點(diǎn)。已被國(guó)內(nèi)外工程實(shí)踐證明是給水系統(tǒng)綜合性能*好的、新型、節(jié)能和環(huán)保型的管材之一，也是一種很有競(jìng)爭(zhēng)力的給水管材，必將對(duì)改善水質(zhì)、提高人們生活水平發(fā)揮無(wú)可比擬的作用。</span></div> <div align="left"><span style="font-size: 14px">　　在建筑給水管系中，由于鍍鋅鋼管已經(jīng)結(jié)束了百年輝煌的歷史，各種新型塑料管及復(fù)合管得到迅速發(fā)展，但各種管材還不同程度地存在著一些不足，遠(yuǎn)不能完全適應(yīng)供水管系的需要和國(guó)家對(duì)飲用水及有關(guān)水品質(zhì)的要求。因此，有關(guān)專(zhuān)家預(yù)言：建筑給水管材*終將恢復(fù)到金屬管的時(shí)代。根據(jù)國(guó)外的應(yīng)用經(jīng)驗(yàn)，在金屬管中認(rèn)定薄壁不銹鋼管為綜合性能*好的管材之一。不銹鋼管材質(zhì)

不銹鋼管的概念不銹鋼管是一種中空的長(zhǎng)條鋼材，大量用作輸送流體的管道，如石油、天燃?xì)狻⑺⒚簹狻⒄魵獾龋硗猓诟銖潯⒖古?qiáng)度相同時(shí)，重量較輕，所以也廣泛用于制造機(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、槍管、炮彈等。

不銹鋼管的應(yīng)用

　　不銹鋼管**可靠、衛(wèi)生環(huán)保、經(jīng)濟(jì)適用，管道的薄壁化以及新型可靠、簡(jiǎn)單方便的連接方法的開(kāi)發(fā)成功，使其具有更多其他管材不可替代的優(yōu)點(diǎn)，工程中的應(yīng)用會(huì)越來(lái)越多，使用會(huì)越來(lái)越普及，前景看好。

不銹鋼管的應(yīng)用

　　隨著我國(guó)改革開(kāi)放政策的實(shí)施，國(guó)民經(jīng)濟(jì)獲得快速增長(zhǎng)，城鎮(zhèn)住宅、公共建筑和旅游設(shè)施大量興建，對(duì)熱水供應(yīng)和生活用水供給提出了新的要求。特別是水質(zhì)問(wèn)題，人們?cè)絹?lái)越重視，要求也不斷提高。鍍鋅鋼管這一常用管材因其易腐蝕性，在國(guó)家相關(guān)政策的影響下，將逐漸退出歷史舞臺(tái)，塑料管、復(fù)合管及銅管成了管道系統(tǒng)的常用管材。但在許多情況下，不銹鋼管更有優(yōu)越性，特別是壁厚僅為0.6～1.2mm的薄壁不銹鋼管在上等飲用水系統(tǒng)、熱水系統(tǒng)及將**、衛(wèi)生放在首位的給水系統(tǒng)，具有**可靠、衛(wèi)生環(huán)保、經(jīng)濟(jì)適用等特點(diǎn)。已被國(guó)內(nèi)外工程實(shí)踐證明是給水系統(tǒng)綜合性能*好的、新型、節(jié)能和環(huán)保型的管材之一，也是一種很有競(jìng)爭(zhēng)力的給水管材，必將對(duì)改善水質(zhì)、提高人們生活水平發(fā)揮無(wú)可比擬的作用。

　　在建筑給水管系中，由于鍍鋅鋼管已經(jīng)結(jié)束了百年輝煌的歷史，各種新型塑料管及復(fù)合管得到迅速發(fā)展，但各種管材還不同程度地存在著一些不足，遠(yuǎn)不能完全適應(yīng)供水管系的需要和國(guó)家對(duì)飲用水及有關(guān)水品質(zhì)的要求。因此，有關(guān)專(zhuān)家預(yù)言：建筑給水管材*終將恢復(fù)到金屬管的時(shí)代。根據(jù)國(guó)外的應(yīng)用經(jīng)驗(yàn)，在金屬管中認(rèn)定薄壁不銹鋼管為綜合性能*好的管材之一。不銹鋼管材質(zhì) 材質(zhì)：

不銹鋼管分類(lèi) 1、按生產(chǎn)方法分類(lèi) （1）無(wú)縫管——冷拔管、擠壓管、冷軋管

不銹鋼無(wú)縫鋼管不銹鋼無(wú)縫鋼管是一種具有中空截面、周邊沒(méi)有接縫的長(zhǎng)條鋼材。

◆ 無(wú)縫鋼管的制造工藝及流程

冶煉＞鋼錠＞軋鋼＞鋸切＞剝皮＞穿孔＞退火＞酸洗＞上灰＞冷拔＞切頭＞酸洗＞入庫(kù)

◆ 無(wú)縫鋼管的特點(diǎn)

從上面的工藝流程我們不難看出：其一、該產(chǎn)品的壁厚越厚,它就越具有經(jīng)濟(jì)性和實(shí)用性,壁厚越薄,它的加工成本就會(huì)大幅度的上升；其次、該產(chǎn)品的工藝決定它的局限性，一般無(wú)縫鋼管精度低：壁厚不均勻、管內(nèi)外表光亮度低、定尺成本高，且內(nèi)外表還有麻點(diǎn)、黑點(diǎn)不易去除；其三、它的檢測(cè)及整形必須離線(xiàn)處理。因此，它在高壓、高強(qiáng)度、機(jī)械結(jié)構(gòu)用材方面體現(xiàn)了它的優(yōu)越性。

（2）焊管；（a）按工藝分類(lèi)——氣體保護(hù)焊管、電弧焊管、電阻焊管（高頻、低頻）

（b）按焊縫分——直縫焊管、螺旋焊管

不銹鋼焊接鋼管

焊接鋼管簡(jiǎn)稱(chēng)焊管，是用鋼板或鋼帶經(jīng)過(guò)機(jī)組和模具卷曲成型后焊接制成的鋼管。

◆ 焊接鋼管的制造工藝及流程

鋼板＞分條＞成型＞溶接＞感應(yīng)光亮熱處理＞內(nèi)外焊道處理＞整形＞定徑＞渦流檢測(cè)＞激光測(cè)徑＞酸洗＞入庫(kù)

◆ 焊接鋼管的特點(diǎn)

從上面的工藝流程我們不難看出：其一、該產(chǎn)品是連續(xù)在線(xiàn)生產(chǎn),壁厚越厚,機(jī)組及溶接設(shè)備的投資就越大,它就越不具有經(jīng)濟(jì)性和實(shí)用性。壁厚越薄,它的投入產(chǎn)出比就會(huì)相應(yīng)下降；其次該產(chǎn)品的工藝決定它的優(yōu)缺點(diǎn)，一般焊接鋼管精度高、壁厚均勻、管內(nèi)外表光亮度高（鋼板的表面等級(jí)決定的鋼管表面亮度）、可任意定尺。因此，它在高精度、中低壓流體應(yīng)用方面體現(xiàn)了它的經(jīng)濟(jì)性及美觀(guān)性。

2、按斷面形狀分類(lèi)（1）圓形鋼管；（2）矩形管； 3、按壁厚分類(lèi)；（1）薄壁鋼管

（2）厚壁鋼管 4、按用途分類(lèi)（1）民用管：分圓管、矩管、花管，一般用于裝飾、建筑、結(jié)構(gòu)等方面；

（2）工業(yè)管：工業(yè)配管用鋼管、一般配管用鋼管（飲用水管）、機(jī)械構(gòu)造／流體輸送管、鍋爐熱交換管、食品衛(wèi)生管等。一般應(yīng)用于工業(yè)的各個(gè)領(lǐng)域如：石油化工、造紙、核能、食品、飲料、醫(yī)藥等行業(yè)對(duì)流體介質(zhì)要求較高管道。不銹鋼管重量計(jì)算公式

不銹鋼管價(jià)格計(jì)算公式

（管坯價(jià)格/折率+加工費(fèi)+利潤(rùn)）*稅收
