安装规程
Installation Instruction
管吊、管托、管墩
管吊为环形,管托和管墩(混凝土)为U形,两端应配固定螺栓。管吊、管托、管墩与管面的接触面至少为180°
在支架上垫3-5mm厚的橡皮并用螺栓固定。凡安装阀门处都应有支托固定。
管架和间距
管架的布置和类型应满足荷重、位移和补偿的要求。管架间距的设计以内装比重1.3的液体,使用温度-40~+80℃为基础。详见附表。
地下安装
对地下安装管道应给予特殊的考虑,除符合上述两条基本要求外,一般应设置砖砌地沟,并在地沟内砌有矮位管墩。沟深度一般是:人行道不浅于40mm车行道不浅于700mm。沟宽度按詹森(Janseil)公式计算,一般为公称直径的二倍,但最窄不得小于500mm,覆土时应两侧同时进行(不允许掺有碎石),并对称夯实。特殊的可用混凝土予制板盖覆。
管与管、管与管件之间联接端必须按规范操作。
管道安装水平偏差<2-3/1000,垂直偏差<2-5/1000,坡度可取3/1000。
Pipe Suspender,Pipe Support,Pipe pier
Pipe suspender is ringlike,while pipe support and pipe pier are U-Shaped The two ends of valves should be Fitted with firm bolt,the contact is at least 1800 between suspender,support,pier and pipe. On the top of stands,there should be a poece of 3 to 5mm thick rubber fixed by bolts. If there are valves on the stand should fixed it
Arrangement of pipe supports
The arrangement and type of pipe supports should meet the requirements of load,displacement and compensation,The conditions for determination of the supports span are that the pipe can filled with liguid.Of sp.gr.1.3and the themperature operating range is-40℃~+80℃.Details are in the additional from
Underground Installation
lnstall pipes under the ground is in a special condition. Besides the above 2 item,it shoud have a brick-1 aid Channelin which should have above piers. Usually the Channel is 400mm deep under the sidewalk and 700mm under the road for car.The with is calculated according to Jamsen, s formual,usually,it is two times of the nominal diameter,bu tthe narrowest can,t be less than 500mm The two sides should be filled and rammed sylmnetrically with clay free of any small stones.Some can be covered with precast concrete slab.
The joint between pipes,pipe and fittings should be operated in a standard way
The hofizontal deviation of pipehng 2-3/1000,While the vertical deviation 2-5/1000,and the gradient of pipeline may be 3/1000.
