管道补偿量计算.doc

补偿器的正确安装和管道补偿量的计算方式发布日期：2010-07-08 一般情况下允许不装补偿器的直管段最大长度民用建筑为33m，工业建筑为42m。（管道伸长量分别为40mm和50mm）。能进行自然补偿部分管道确定了，其余部分就是应该设置补偿器的部分。计算这部分伸长量，如果较长要设置多个补偿器，应注意均匀设置；并在两个补偿器中间设置固定支架。选择时注意套筒补偿器容易漏水漏气，适合安装在地沟内，不适宜安装在建筑物上部；波纹管补偿器能力大耐腐蚀，但造价高并且需要设置导向支架；方形补偿器需要的安装空间较大，但运行可靠应用广泛。设计时可以根据工程具体情况选用。管道的热伸长量计算方法: X=0.012*(T1-T2)*L X管道的热伸长量,mm;t1热媒温度,t2管道安装时的温度, ,一般按-5计算.L计算管道长度m;0.012钢铁的线膨胀系数,mm/m直埋内压式波纹补偿器参数直埋式波纹补偿器主要适用于轴向补偿，同时具有超强抗弯能力，所以不考虑管道下沉的影响。直埋式波纹补偿外壳及导向套筒保护下实现自由伸缩补偿，其它性能跟普通波纹补偿器相同。规格参数通径 DN波数压力等级MPa波纹管有效面积 cm2最大外径尺寸 mm接管端口尺寸 mm总长L (mm)0.250.61.01.62.5轴向补偿量mm/刚度N/mm50814/15312/31812/31812/635113.53611627/7624/15824/15824/31823/6554453252/3848/7948/7948/15946/32862165819/21318/21318/21318/42415/8415515973x43771230/14229/14227/14227/28325/4214252460/7158/10754/10754/14250/21158180830/17930/17930/35829/35827/6508116289x44301054/14337/14337/28637/28632/32546620108/7274/7274/14374/14364/163660100634/13834/27733/41733/41732/817121180108x44101056/8356/16656/25054/25050/40949220112/42112/83112/125108/125100/205712125537/13636/27236/40835/40833/801180221133x4410966/7665/15165/22763/22760/40141218132/38130/76130/114126/114120/201711150549/10049/20048/30045/45644/845257245159x4.5433888/6378/12577/18871/28665/42351816159/32156/63154/94142/143130/211756200458/9556/19356/28856/48055/800479327219x6475686/6385/12885/19284/32080/92755312172/32170/64170/96168/160160/200800250475/17074/34363/58853/93050/1856769404273x85006112/113110/22895/39280/62078/92762012220/57220/114190/196160/310156/464984300473/25072/50365/83057/125354/21421105451325x85846110/167109/33597/55385/83580/107171312220/84218/168194/277170/481160/5361113350479/26378/52372/84064/126562/26841307500377x106146119/175117/348107/56097/84390/134275912238/88234/174214/280194/442180/6711216400483/28073/45870/91865/137363/36751611537426x106256126/187109/305102/61297/91590/183877112250/94218/153204/306194/458180/9201225450498/20396/40582/69069/230565/43501972632478x106206147/135144/270124/460103/153790/217576212294/68288/135248/230206/769180/108712005004102/212100/42384/72870/245265/42562445699529x106246153/142149/282126/485105/163590/212876612306/71298/141252/243210/818180/106412166004123/265121/53086/146899/174095/28423534806630x106766185/177181/353148/978140/1160120/142084812370/89362/177358/489280/580240/71013827004128/287126/57387/162585/297284/41004717915720x107086192/192188/382168/1083131/1982120/205088212384/96376/191336/542262/991240/1102514228004128/310126/62084/177885/318384/623458221005820x107248256/155252/310168/889170/1591168/3117107112384/103378/207252/596241/1061236/155815389004151/378149/758118/1329117/257576201137920x101928302/189298/379236/664234/1288121112453/126447/253
