你好!很高兴为你解答，C-PVC塑料管材是PVC-C材质。
　　PVC-C材质机械强度高，适于受压场合。使用温度高达90摄氏度左右，寿命可达50年.安全简便，连接方法为熔剂粘接，螺纹连接，法兰连接和焊条连接。阻燃、防火、导热性低，管道热损少，安装费用低，但要注意使用的胶水有毒性。
　　PVC-C树脂为母料，加入抗冲剂，稳定剂等辅料经高速挤出而成的新型埋地式高压电力电缆保护管。
　　该产品具有高强度、柔韧性好、耐高温、耐腐蚀、阻燃、绝缘性能良好、无污染、不易老化、质轻、施工方便等特点，其各项性能指标经国家级、省检测、鉴定和认证，均已达到或超过国内的同类产品水平。产品性能大优于传统的石棉电缆排管及普通PVC管材，是传统电力电缆护套管的理想替代品。

你好，在制作和安装时，应注意事项:
(1)支架制作时，应依照国标图集上规定的型钢规格，不得随意变更。
(2)凡风道支架上的螺栓孔一律采用钻孔，不得采用气焊割孔。
(3)带有斜支撑的托架，焊缝应为满焊。
(4)吊架中吊杆下料应准确，吊杆中间不宜出现搭接焊缝。
(5)当风道断面较小时，风道吊杆可采用膨胀螺栓固定在楼板上，当风道较大时，应采用钻孔因定的方式。
(6)支架在安装前，应在墙休、柱体和楼板面上弹出风道的中心线，然后再确定支架的水平位置及标高，可保证安装后的风道的水平度和平面中心位置。
(7)支架安装前，应对外露部分进行除锈、刷防锈漆处理。
(8)凡低温风道，为了防止产生冷桥，在风管与支架的接触面上应垫木方或木块。
(9)墙体上安装的支架，安装调平后，应采用C20混凝土堵洞并捣实与结构面平。
(10)当采用在墙、柱体上预理钢构件时，在土建浇注混凝土
前，应复核钢构件的位置和标高。
(11)无特殊要求时，风道支架的间距一般为3m,但在不足3m的风道应在两端各安装一支架，在三通或弯头处官加设支架。
(13)在风道支架上不得安装其他专业的管道或线缆。

1)胶水使用中要注意足量使用(但也不可过量，防止污染管材/管件/阀门)，溢出的胶水圈要完整/无气泡。 2”以上管道应使用清洁剂预处理，清洁剂在使管道表面软化之目的,切勿残留在管道内部.
2)胶水涂胶前要先对管材/管件检查配合恰当，涂胶面注意清洁无杂物、灰尘、水渍、油污等，并对涂胶深度作标记。管道涂胶后应能使管道表面充分软化，切记要在胶水保持湿润时粘结管材/管件；
3)管材/管件接合时要注意确保承插到底，6”以上管道黏结时要使用牵引器操作，防止管道回退；
4)球阀粘结时应先水平粘结好球阀/管路，再将连接组合连接到管路上，球阀连接时注意球体打开；
5)注意固化时间充分(冬季要延长时间)，管道在胶水的固化过程中不要承压/受力。
希望对你有帮助！

1.   材料规格选择：DN100150以上的管道，角钢为L40X40X4;DN100以下的管道，固定支角钢为L30X30X3。    　　
2.   支架类型选择：DN150以上的管道，固定支架为龙门架;DN100以下的管道，固定支架为吊架。    　　
3.   安装位置位置选择：DN100以上的管道，固定支架安装于次梁底部。    　　
4.   长度确定：贴梁的长度(约25cm)加上管道的水平中心垂直的距离。然后减去管道的半径。    　　
5.   支架安装方法：拉一支线作为支架安装的水平线，随后，沿着这支线按规定的间距安装若干个支架。　　
6.   固定螺栓规格选择：膨胀螺栓选用12#。    　　
7.   安装间距确定：同一支主管的支架间距≤3米;
