style="text-indent:25px">薄壁不銹鋼水管的壁厚是管道連接強(qiáng)度的關(guān)鍵。壁厚減少到安全系數(shù)以下，可靠性必然下降幾個(gè)等級(jí)。實(shí)際上管道的壁厚是保證管道連接的強(qiáng)度，同時(shí)，壁厚還具有在各種環(huán)境下抗振的功能、管道耐外力沖撞的性能、及隱蔽工程中的使用壽命和抗腐蝕等能力。這里著重介紹不銹鋼管件的壁厚對(duì)連接與使用壽命的關(guān)系。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(duì)管件的壁厚會(huì)產(chǎn)生較大影響。彎管對(duì)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(shí)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 style="text-indent:25px">在管材彎曲設(shè)計(jì)和選用材料壁厚時(shí)，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(shí)，彎管半徑的大小，也會(huì)對(duì)壁厚產(chǎn)生較大影響。脹形對(duì)管件壁厚的影響。管件脹形是在壓力作用下使管材沿徑向擴(kuò)張的成形，脹形既可以完成管坯的局部擴(kuò)張，也可完成管坯的整體擴(kuò)張。脹形過程可分為："軸向無收縮"和"軸向有收縮"變形方式。軸向無收縮變形：脹形部位完全靠管坯壁厚的局部變薄而成形，變形性質(zhì)是在管材毛坯上端的局部成形，管材下端壁厚不變?。ㄒ妶D1)。如管件三通的脹形是"軸向無收縮變形"。軸向有收縮變形：在脹形部位管坯壁厚局部變薄的同時(shí)，還伴有一定的管坯軸向的自由收縮(見圖2)。如管件U形槽的形成是靠局部變薄成形，是"軸向有收縮的變形"。不銹鋼材料吊運(yùn)，不能與其他金屬直接接觸，應(yīng)加墊木板或橡膠板等非金屬材料。</p><div

傳統(tǒng)的焊接和法蘭連接的管道連接方式，不但需要有相應(yīng)技能的焊接工人，而且費(fèi)時(shí)，工人的操作難度大，并存在焊接煙塵的污染。由于操作空間和焊接技能的差異，焊接質(zhì)量和外觀都難以達(dá)到滿意的結(jié)果，從而影響工程的整體質(zhì)量。304不銹鋼管件生銹的原因是表面膜被破壞。在不銹鋼的表面含有很多其他金屬元素的粉塵或者是異類金屬顆粒的附著物，在潮濕的空氣中，當(dāng)附著物與不銹鋼之間的冷凝水將兩者連成了一個(gè)微電池，就會(huì)發(fā)生電化學(xué)反應(yīng)，終破壞保護(hù)膜，這一類是電化學(xué)腐蝕。位于內(nèi)層的橡膠密封圈置于被連接管道的外側(cè)，并與預(yù)先滾制的溝槽相吻合，再在橡膠圈的外部扣上卡箍，然后用二顆螺栓緊固即可。由于其橡膠密封圈和卡箍采用特有的可密封的結(jié)構(gòu)設(shè)計(jì)，使得溝槽連接件具有良好的密封性，并且隨管內(nèi)流體壓力的增高，其密封性相應(yīng)增強(qiáng)。
