無(wú)縫鋼管是一種具有中空截面、周邊沒(méi)有接縫的圓形，方形，矩形鋼材。 </p> <p> 無(wú)縫鋼管是用鋼錠或?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。無(wú)縫鋼管大量用作輸送流體的管道。鋼管與圓鋼等實(shí)心鋼材相比，在抗彎抗扭強(qiáng)度相同時(shí)，重量較輕，是一種經(jīng)濟(jì)截面鋼材，寬泛用于制造結(jié)構(gòu)件和機(jī)械零件，如石油鉆桿、汽車(chē)傳動(dòng)軸、自行車(chē)架以及建筑施工中用的鋼腳手架等。無(wú)縫鋼管制造環(huán)形零件，可提高材料利用率，簡(jiǎn)化制造工序，節(jié)約材料和加工工時(shí)，如滾動(dòng)軸承套圈、千斤頂套等，目前已寬泛用鋼管來(lái)制造。 </p> <p> 鋼管還是各種常規(guī)武器不可缺少的材料，炮筒等都要鋼管來(lái)制造。鋼管按橫截面積形狀的不同可分為圓管和異型管。由于在周長(zhǎng)相等的條件下，圓面積較大，用圓形管可以輸送更多的流體。此外，圓環(huán)截面在承受內(nèi)部或外部徑向壓力時(shí)，受力較均勻，因此，絕大多數(shù)鋼管是圓管。 </p> <p> 濟(jì)寧冠翔物資有限公司銷(xiāo)售的鋼材常年庫(kù)存萬(wàn)噸以上，保證供貨的充足與調(diào)整。有利于需求商的不間斷使用。冠翔物資交貨準(zhǔn)時(shí)，絕不拖欠，多年的經(jīng)營(yíng)與銷(xiāo)售已為其贏得了良好的口碑與市場(chǎng)。歡迎有更多的需求商前來(lái)淺談合作。共同發(fā)展！ </p> <p> <br />

</p> <p> 范圍長(zhǎng)度：范圍長(zhǎng)度在通常長(zhǎng)度范圍內(nèi)，當(dāng)用戶(hù)要求其中某一固定范圍長(zhǎng)度時(shí)，需在合同中注明。 </p> <p> 例如：通常長(zhǎng)度為3000～12000mm，而范圍定尺長(zhǎng)度為6000～8000mm或8000～10000mm。 </p> <p> 可見(jiàn)，范圍長(zhǎng)度比定尺和倍尺長(zhǎng)度要求寬松，但比通常長(zhǎng)度加嚴(yán)很多，也會(huì)給生產(chǎn)企業(yè)帶來(lái)成材率的降低。因此生產(chǎn)企業(yè)提出加價(jià)是有道理的，其加價(jià)幅度一般在基價(jià)上加價(jià)4%左右。 </p><p> 無(wú)縫鋼管的規(guī)格及作用 </p> <p>

<br /> 一般用無(wú)縫鋼管要保證強(qiáng)度和壓扁試驗(yàn)。熱軋鋼管以熱軋狀態(tài)或熱處理狀態(tài)交貨；冷軋以熱以熱處理狀態(tài)交貨。低中壓鍋爐用無(wú)縫鋼管：用于制造各種低中壓鍋爐、過(guò)熱蒸汽管、沸水管、水冷壁管及機(jī)車(chē)鍋爐用過(guò)熱蒸汽管、大煙管、小煙管和拱磚管等。這樣就可以使鋼管受力均勻又能保證質(zhì)量。
