不銹鋼焊管的生產(chǎn)質(zhì)量受到多方面因素的影響，其中就包括生產(chǎn)場(chǎng)地的環(huán)境因素，不銹鋼焊管廠家在進(jìn)行產(chǎn)品質(zhì)量控制時(shí)不可忽視這一部分的影響。 </p> <p> 1.不銹鋼焊管生產(chǎn)需有**的生產(chǎn)車間或**固定生產(chǎn)場(chǎng)地，不銹鋼原材料要保證單獨(dú)存放，不能與碳鋼混放。 </p> <p> 2.不銹鋼焊管原料和半成品在周轉(zhuǎn)和運(yùn)輸過(guò)程中，應(yīng)配備必要的防鐵離子污染和磕傷、劃傷的運(yùn)輸工裝。 </p> <p> <br /> </p> <p> <br /> </p><p> 不銹鋼焊管： </p> <p> 不銹鋼焊管，簡(jiǎn)稱焊管，常用鋼材或鋼帶經(jīng)過(guò)機(jī)組和模具卷曲成型后焊接制成的鋼管。焊接鋼管生產(chǎn)工藝簡(jiǎn)單，生產(chǎn)效率高，品種規(guī)格多，設(shè)備投資少，但一般強(qiáng)度低于無(wú)縫鋼管。20世紀(jì)30年代以來(lái)，隨著質(zhì)量帶鋼連軋生產(chǎn)的迅速發(fā)展以及焊接和檢驗(yàn)技術(shù)的進(jìn)步，焊縫質(zhì)量不斷提高，焊接鋼管的品種規(guī)格日益增多，并在越來(lái)越多的領(lǐng)域尤其是在換熱設(shè)備用管、裝飾管、中低壓流體管等方面代替了無(wú)縫鋼管。 </p> <p> <p> 特點(diǎn)編輯其一、小口徑不銹鋼焊管是連續(xù)在線生產(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)性及美觀性。
