本工程污水管道的接口設(shè)計考慮到本工程位于##區(qū)，管道易于沉降所以采用承插式柔性接口，以防管道不均勻沉降和提高管道的密封性能。承插式膠圈柔接口安裝時應(yīng)注意以下事項： </p> <p> ①安裝前應(yīng)徹底清潔接頭內(nèi)的表面、凹槽，止推圈和橡膠圈，應(yīng)確保其無油污灰塵 </p> <p> ②安裝密封圈時應(yīng)確保密封圈與凹槽、管壁均勻貼合，并在安裝前使用潤滑劑封圈。 </p> <p> <br /> 南寧球墨鑄鐵管新報價廣西球墨鑄鐵管廠家。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="南寧DN700球墨鑄鐵管,管"

3、控制原料加入，降低夾渣缺陷 </p> <p> 為解決降低鐵液中的含硫量，減少硫化物的產(chǎn)生，應(yīng)控制W(S)<0.02%;適當(dāng)提高澆鑄溫度，有利于夾渣上浮;球化劑中稀土含量不易過高，稀土含量控制在1-2%為宜;加強鐵液的扒渣和擋渣效果;鐵液中的殘鎂流量不易過高(控制在0.035-0.045%)，以減少鐵液表面氧化。 </p> <p> 通過采取以上相應(yīng)措施，球墨鑄鐵管的質(zhì)量得到明顯改善，裂紋、重皮、夾渣缺陷大為降低，減少了廢品，大幅提高綜合成材率。二、安裝應(yīng)注意的幾個問題 </p> <p> 1．膠圈應(yīng)在承口槽內(nèi)放正，并用手壓實。 </p> <p> <br /> 球墨鑄鐵管-云南球墨鑄鐵管廠-勘仁-生產(chǎn)供應(yīng)。</p><div
