產(chǎn)品描述

水泥砂漿防腐鋼管可用于市政工程:適用高層建筑給水、熱網(wǎng)供熱、自來水工程、燃?xì)廨斔?、埋地輸水等管道。石油:石油輸送管道、化工制藥、印染等行業(yè)輸送腐蝕性介質(zhì)的工藝管道。污水處理:污水處理排放管、污水管以及生物池防腐工程農(nóng)業(yè):農(nóng)業(yè)灌溉用管、深井管、排水管等網(wǎng)路,耐腐蝕性能優(yōu)于鋼結(jié)構(gòu)有利于鋼管的抗火和防火。

水泥砂漿防腐鋼管
100號水泥砂漿是指它的強(qiáng)度是100kg/cm2,但是全部改成以MPa為單位了,100號對應(yīng)于M10。配合比根據(jù)原材料不同、砂漿用途不同而不同,以常用的42.5普通硅酸鹽水泥、中砂配100(M10)砌筑砂漿為例:水泥305kg:砂1.10m3:水183kg。  砂漿的標(biāo)號有M3,M5,M7.5,M10,M12.5,M15,M20,M25,M30,M40幾種。砂漿按用途分有砌筑、抹灰、接縫幾種,和標(biāo)號無關(guān)。水泥砂漿工作完成后還有最重要的一道工序,那就是風(fēng)干。就是指在自然狀態(tài)下風(fēng)干2-3天。主要是防止在裝運(yùn)的途中由于顛簸導(dǎo)致水泥砂漿出現(xiàn)裂縫。
由于鋼管內(nèi)填有混凝土,能吸收大量的熱能,因此遭受火災(zāi)時管柱截面溫度場的分布很不均勻,增加了柱子的耐火時間,減慢鋼柱的升溫速度,并且一旦鋼柱屈服,混凝土可以承受大部分的軸向荷載,防止結(jié)構(gòu)倒塌。組合梁的耐火能力也會提高,因?yàn)殇摿旱臏囟葧捻敳恳砭壈褵崃總鬟f給混凝土而降低。經(jīng)實(shí)驗(yàn)統(tǒng)計數(shù)據(jù)表明:達(dá)到一級耐火3小時要求和鋼柱相比可節(jié)約防火涂料1/3一2/3甚至更多,隨著鋼管直徑增大,節(jié)約涂料也越多。

防腐鋼管用于:市政工程:適用高層建筑給水、熱網(wǎng)供熱、自來水工程、燃?xì)廨斔汀⒙竦剌斔裙艿?。石油:石油輸送管道、化工制藥、印染等行業(yè)輸送腐蝕性介質(zhì)的工藝管道。
污水處理:污水處理排放管、污水管以及生物池防腐工程農(nóng)業(yè):農(nóng)業(yè)灌溉用管、深井管、排水管等網(wǎng)路,耐腐蝕性能優(yōu)于鋼結(jié)構(gòu)有利于鋼管的抗火和防火
