<p> 管件選用標(biāo)準(zhǔn)中其實是存在的問題，一般國內(nèi)的管件標(biāo)準(zhǔn)不健全、不配套管件標(biāo)準(zhǔn)應(yīng)包括管件的型式參數(shù)標(biāo)準(zhǔn)與管件材料標(biāo)準(zhǔn)。但材料標(biāo)準(zhǔn)中或是規(guī)定不全，或是缺乏諸如汀貨要求、檢驗及組批規(guī)則、質(zhì)量證明等方面的質(zhì)量技術(shù)要求。管件材料標(biāo)準(zhǔn)配套性差，往往從各自的立場、角度，而不是從壓力管道整個標(biāo)準(zhǔn)體系出發(fā)來制訂。工程中的選用，管材標(biāo)準(zhǔn)有，但無相應(yīng)的鍛件或鑄件標(biāo)準(zhǔn)?，F(xiàn)實是管件鍛件標(biāo)準(zhǔn)借用壓力容器的鍛件標(biāo)準(zhǔn)，沒有考慮兩者的差異，如焊接、拍片檢驗等規(guī)定。

不銹鋼管件在工程中的應(yīng)用將越來越普遍，具有廣闊的前景。由于不銹鋼對建筑材料有許多理想的性能要求，可以說是一種獨特的金屬，并在不斷發(fā)展。為了使不銹鋼在傳統(tǒng)應(yīng)用中具有更好的性能，對現(xiàn)有的不銹鋼品種進(jìn)行了改進(jìn)，開發(fā)了新的不銹鋼，以滿足先進(jìn)建筑應(yīng)用的嚴(yán)格要求。由于生產(chǎn)效率和質(zhì)量的不斷提高，不銹鋼已成為建筑師選擇的成本效益高的材料之一。不銹鋼管件集性能，外觀和使用特性，它仍然是挺好的不銹鋼建材的一個。不銹鋼管件的不銹性和耐腐蝕性是由于其表面形成了富鉻氧化膜（鈍化膜）所致。不銹鋼管件和耐腐蝕性是相對的。 </p> <p> <br /> </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> </p> <p> 管件在生產(chǎn)過程中要經(jīng)過下料、彎管、成型（冷擠壓、脹型）等多道工序。首先影響壁厚的主要是彎管、成型等工序。采用的成型工藝不同，對管件的壁厚會產(chǎn)生較大影響。其中之一就是彎管對管件壁厚的影響。管材彎曲成型中，管材彎曲的形狀變化是材料位移，是塑性變形的表面現(xiàn)象，其變形實質(zhì)在于管壁外則伸長減薄、管材內(nèi)則縮短增厚。管壁厚度的減薄量是隨材料硬化指數(shù)增大而增加。 </p> <p> 所以在管材彎曲設(shè)計和選用材料壁厚時，應(yīng)考慮到管材的伸長性能以及彎管外側(cè)變薄的重要因素，采用合理的壁厚管材，否則彎曲拉伸后外側(cè)壁厚很難保證尺寸要求，同時，彎管半徑的大小，也會對壁厚產(chǎn)生較大影響。 </p> <p> <br /> </p> <p> <br /> 鍍鋅管的使用壽命約為10年，而不銹鋼彎管的使用壽命一般為70年。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="連云港管帽管件哪家好,管"
