style="text-indent:25px">現(xiàn)在在市面上銷售的封頭大多都有防腐蝕、抗壓能力強(qiáng)、承重量大、密封性能好等特點，更重要的他在制作的過程中選用的材料廉價易得，總的制作成本十分低，封頭沒有鋼鐵結(jié)構(gòu)，整個結(jié)構(gòu)是用新型材料制成，沒有任何回收利用的價值，這樣就較大的避免了封頭被盜走的情況，要知道在使用鋼鑄封口材料的時期，經(jīng)常有報道說某處的這類器材被盜走。封頭擁有非常強(qiáng)的防腐蝕能力，封頭廠中封頭的出廠標(biāo)準(zhǔn)就是在硫酸中浸泡48個小時，質(zhì)量損失不超過百分之一，可想而知它的防腐能力有多么厲害，人們就不用擔(dān)心長久的日曬雨淋會對封頭造成損壞，從而出現(xiàn)井蓋易脆粉碎，以至于造成意外事故。封頭在抗壓承重方面的能力是經(jīng)過專業(yè)軟件測試后而選用新型的高分子材料經(jīng)過高溫高壓鍛造而成的，可以承重40噸以上。常州球冠形封頭生產(chǎn)廠家直銷球形封頭的制造減薄量比橢圓形封頭和碟形封頭都要大一些，約15%。</p><div

style="text-indent:25px">橢圓封頭劃傷主要是在搬運過程中，操作不當(dāng)引起的。例如：吊鉤劃痕，叉車劃痕。解決方法：先在吊鉤和叉車與封頭接觸面墊保護(hù)膜，出現(xiàn)劃傷后，進(jìn)行打磨，嚴(yán)重的進(jìn)行補(bǔ)焊，劃傷面積超過百分之二十五要整體處理。如何增加橢圓封頭減薄率？成型封頭的厚度均勻可以避免應(yīng)力集中，增加封頭的使用周期，根據(jù)制造工藝確定加工裕量，以確保凸形封頭和熱卷筒節(jié)成形后的厚度不小于該部件的名義厚度減去鋼板負(fù)偏差。橢圓封頭大多數(shù)的橘皮現(xiàn)象出于板材本身有分層現(xiàn)象，然而肉眼是觀察不出來的，只能是在沖壓，壓鼓工序中，橘皮現(xiàn)象才能被發(fā)現(xiàn)。</p><p
