2、按外形分類有圓形管、異形管之分。異形管除方形管和矩形管外，還有橢圓管、半圓管、三角形管、六角形管、凸字形管、梅花形管等。 3、按材質(zhì)的不同，分為普通碳素結(jié)構(gòu)管、低合金結(jié)構(gòu)管、優(yōu)良碳素結(jié)構(gòu)管、合金結(jié)構(gòu)管、不銹管等。 4、按專門用途分，有鍋爐管、地質(zhì)管、石油管等。無(wú)縫管規(guī)格：無(wú)縫管按GB/T8162-87規(guī)定 1、規(guī)格：熱軋管外徑32～630mm。壁厚2.5～75mm。冷軋(冷拔)管外徑5～200mm。壁厚2.5～12mm。 2、外觀質(zhì)量：圓管的內(nèi)外表面不得有裂縫、折疊、軋折、離層、發(fā)紋和結(jié)疤缺陷存在。這些缺陷應(yīng)完全清理掉，清理后不得使壁厚和外徑超過(guò)負(fù)偏差。 3、圓管的兩端應(yīng)切成直角，并清理毛刺。壁厚大于20mm的圓管允許氣割和熱鋸切割。經(jīng)供需雙方協(xié)議也可不切頭。 4、冷拔或冷軋精密無(wú)縫圓管《表面質(zhì)量》參照GB3639-83。</p><p style="text-indent:25px">熱軋（擠壓無(wú)縫圓管）：圓管坯→加熱→穿孔→三輥斜軋、連軋或擠壓→脫管→定徑（或減徑）→冷卻→矯直→水壓試驗(yàn)（或探傷）→標(biāo)記→入庫(kù)軋制無(wú)縫管的原料是圓管坯，圓管胚要經(jīng)過(guò)切割機(jī)的切割加工成長(zhǎng)度約為1米的坯料，并經(jīng)傳送帶送到熔爐內(nèi)加熱。鋼坯被送入熔爐內(nèi)加熱，溫度大約為1200攝氏度。燃料為氫氣或乙炔。爐內(nèi)溫度控制是關(guān)鍵性的問(wèn)題.圓管坯出爐后要經(jīng)過(guò)壓力穿孔機(jī)進(jìn)行穿空。一般較常見(jiàn)的穿孔機(jī)是錐形輥穿孔機(jī)，這種穿孔機(jī)生產(chǎn)效率高，產(chǎn)品質(zhì)量好，穿孔擴(kuò)徑量大，可穿多種鋼種。穿孔后，圓管坯就先后被三輥斜軋、連軋或擠壓。擠壓后要脫管定徑。定徑機(jī)通過(guò)錐形鉆頭高速旋轉(zhuǎn)入鋼胚打孔，形成圓管。圓管內(nèi)徑由定徑機(jī)鉆頭的外徑長(zhǎng)度來(lái)確定。圓管經(jīng)定徑后，進(jìn)入冷卻塔中，通過(guò)噴水冷卻，圓管經(jīng)冷卻后，就要被矯直。圓管可用于管道、熱工設(shè)備、機(jī)械工業(yè)、石油地質(zhì)鉆探、容器、化學(xué)工業(yè)和特殊用途。</p><div

不定尺:（通常長(zhǎng)度）鍍鋅無(wú)縫管長(zhǎng)度一般都是長(zhǎng)短不一，這種在標(biāo)準(zhǔn)規(guī)定范圍內(nèi)的叫不定尺。不定尺長(zhǎng)度又叫通常長(zhǎng)度（通尺）。例如，159*4.5鍍鋅無(wú)縫管其通常長(zhǎng)度規(guī)定為8～12.5m。 2. 定尺:按訂貨要求切成固定尺寸的稱為定尺。按定尺長(zhǎng)度交貨時(shí)，所交鍍鋅無(wú)縫管必須具有需方在訂貨合同中指定的長(zhǎng)度。例如，合同上注明按定尺長(zhǎng)度6m 交貨，則所交貨的材料必須都是6m 長(zhǎng)的，短于6m 或長(zhǎng)于6m 均為不合格。但實(shí)際上交貨不可能都是6m 長(zhǎng)，因此規(guī)定了允許有正偏差，而不允許有負(fù)偏差。（定尺長(zhǎng)度不大于6m時(shí)，其允許偏差擴(kuò)大到+30mm；定尺長(zhǎng)度大于6m時(shí)，其允許偏差擴(kuò)大到+50mm）無(wú)縫管理論計(jì)算公式： (外徑–壁厚 )×壁厚 ×0.02466= 無(wú)縫管每米的重量{公斤}。廣東熱軋無(wú)縫管供應(yīng)</p><p style="text-indent:25px">受國(guó)際油價(jià)走高影響，近幾年原油表觀消費(fèi)量持續(xù)增長(zhǎng)，油套管用量增加，無(wú)縫管廠目標(biāo)市場(chǎng)分化。廣東熱軋無(wú)縫管供應(yīng)</p><p style="text-indent:25px">鍍鋅無(wú)縫管長(zhǎng)度尺寸的知識(shí)： 1、倍尺:按訂貨要求的固定尺寸切成整倍數(shù)的稱為倍尺。按倍尺長(zhǎng)度交貨時(shí)，所交鍍鋅無(wú)縫管的長(zhǎng)度必須為需方在訂貨合同中指定的長(zhǎng)度（叫單倍尺）的整數(shù)倍數(shù)（另加鋸口）。例如，需方在訂貨合同中要求單倍尺長(zhǎng)度為2m ，那么，切成雙倍尺時(shí)長(zhǎng)度即為4m ，切成3 倍尺時(shí)即為6m ，并分別加上一個(gè)或兩個(gè)鋸口量。鋸口量在標(biāo)準(zhǔn)中有規(guī)定。倍尺交貨時(shí)，只允許有正偏差，不允許出現(xiàn)負(fù)偏值。 2、短尺:長(zhǎng)度小于標(biāo)準(zhǔn)規(guī)定的不定尺長(zhǎng)度下限，但不小于允許的較短長(zhǎng)度的叫短尺。例如，流體輸送圓管標(biāo)準(zhǔn)中規(guī)定，允許每批有10% 的（按根數(shù)計(jì)算） 2-4m長(zhǎng)的短尺圓管。4m即為不定尺長(zhǎng)度的下限，允許的較短長(zhǎng)度為2m。廣東熱軋無(wú)縫管供應(yīng)</p></p><br /><p>文章來(lái)源地址: http://www.cdcfah.com/cp/3167887.html</p></div></div></div></div></div><div id="nvlj7rx"
