質(zhì)量管理并不是質(zhì)量越好，使用就好。一定本著質(zhì)量管理的精髓：“適合而持續(xù)”。“適合”是指滿足自己的要求，本來用0.4mpa的管道就行，選1.0mpa的就是浪費(fèi)，本來自己施工不可能達(dá)到國標(biāo)要求，而選用國標(biāo)管，***還不如選用沖擊提高1.5倍，壓力略降的管道。造成投資大，使用風(fēng)險(xiǎn)高。（國標(biāo)安裝中暗傷要多于沖擊好的管材）?！俺掷m(xù)”是指每批產(chǎn)品的質(zhì)量相同，要按照ＩＳＯ9000的標(biāo)準(zhǔn)持續(xù)穩(wěn)定。這主要看廠家的管理。特別是質(zhì)量管理，這與設(shè)備、與模具無關(guān)。與企業(yè)質(zhì)量管理與意識相關(guān)。企業(yè)的存活年限與企業(yè)的質(zhì)量意識有關(guān)。對于抗沖擊達(dá)不到國標(biāo)，壓力試驗(yàn)達(dá)不到1.5倍使用壓力的管道，不能選用。特別是抗沖擊指標(biāo)，否則會(huì)引起使用者很多煩惱。</p><div
