请问室内采暖管道设计方案：1范围本工艺标准适用于民用及一般工业建筑热水温度不超过150℃的采暖管道安装工程。2施工准备2.1材料要求：2.1.1管材：碳素钢管、无缝钢管。管材不得弯曲、锈蚀，无飞刺、重皮及凹凸不平现象。2.1.2管件：无偏扣、方扣、乱扣、断丝和角度不准确现象。2.1.3阀门：铸造规矩、*刺、无裂纹、开关灵活严密，丝扣无损伤，直度和角度正确，强度符合要求，手*无损伤。有出厂合格证，安装前应按有关规定进行强度、严密性试验。2.1.4其它材料：型钢、圆钢、管卡子、螺栓、螺母、油、麻、垫、电气焊条等。选用时应符合设计要求。2.2主要机具：2.2.1机具：砂*锯、套丝机、台钻、电焊机、煨弯器等。2.2.2工具：压力案、台虎钳、电焊工具、管钳、手锤、手锯、活扳子等。2.2.3其它：钢卷尺、水平尺、线坠、粉笔，小线等。2.3作业条件2.3.1干管安装：位于地沟内的干管，应把地沟内杂物清理干净，安装好托吊卡架，未盖沟盖板前安装。位于楼板下及顶层的干管，应在结构封顶后或结构进入安装层的一层以上后安装。2.3.2立管安装必须在确定准确的地面标高后进行。2.3.3支管安装必须在墙面抹灰后进行。3*作工艺3.1工艺流程：安装准备→预制*→卡架安装→干管安装→立管安装→支管安装→试压→冲洗→防腐→保温→调试3.2安装准备：3.2.1认真熟悉图纸，配合土建施工进度，预留槽洞及安装预埋件。3.2.2按设计图纸画出管路的位置、管径、变径、预留口、坡向，卡架位置等施工草图，包括干管起点、末端和拐弯、节点。预留口、坐标位置等。3.3干管安装：3.3.1按施工草图，进行管段的*预制，包括：断管、套丝、上零件、调直、核对好尺寸，按环路分组编号，码放整齐。3.3.2安装卡架，按设计要求或规定间距安装。吊卡安装时，先把吊棍按坡向、顺序依次穿在型钢上，吊环按间距位置套在管上，再把管抬起穿上螺栓拧上螺母，将管固定。安装托架上的管道时，先把管就位在托架上，把第一节管装好U形卡，然后安装第二节管，以后各节管均照此进行，紧固好螺栓。3.3.3干管安装应从进户或分支路点开始，装管前要检查管腔并清理干净。在丝头处涂好铅油缠好麻，一人在末端扶平管道，一人在接口处把管相对固定对准丝扣，慢慢转动入扣，用一把管钳咬住前节管件，用另一把管钳转动管至松紧适度，对准调直时的标记，要求丝扣外露2～3扣，并清掉麻头依此方法装完为止（管道穿过伸缩缝或过沟处，必须先穿好钢套管）。3.3.4制作羊角弯时，应煨两个75°左右的弯头，在联接处锯出坡口，主管锯成鸭嘴形，拼好后即应点焊、找平、找正、找直后，再进行施焊。羊角弯接合部位的口径必须与主管口径相等，其弯曲半径应为管径的2.5倍左右。干管过墙安装分路作法见图1-11。3.3.5分路阀门离分路点不宜过远。如分路处是系统的最低点，必须在分路阀门前加泄水丝堵。集气罐的进出水口，应开在偏下约为罐高的1/3处。丝接应与管道联接调直后安装。其放风管应稳固，如不稳可装两个卡子，集气罐位于系统末端时，应装托、吊卡。3.3.6采用焊接钢管，先把管子选好调直，清理好管膛，将管运到安装地点，安装程序从第一节开始；把管就位找正，对准管口使预留口方向准确，找直后用气焊点焊固定（管径≤50mm以下焊2点，管径≥70mm以上点焊3点），然后施焊，焊完后应保证管道正直。

1室内供暖管道安装的基本要求(1)采暖管道采用输送低压流体的钢管,即非镀锌焊接钢管,或称黑铁管。管道安装应有坡度,如设计无要求,其坡度应符合下列规定:热水采暖和热水供应管道及汽水同向流动的蒸汽和凝结水管道。在这种情况下,管道的坡度一般为0.003,但是不能小于0.002,汽水逆向流动的蒸汽和凝结水管道,坡度一般不能小于0.005。(2)在室内采暖管道安装的过程中,管道从门窗或从其他洞口、梁、柱、墙垛等处绕过,其转角处如高于或低于管道水平走向,在其最高点或最低点应分别安装排气和泄水装置,这样的主要作用就是排除管道中的空气和最低处的脏物等。(3)在设置管道穿过楼板和墙壁的时候,应该设置铁皮或者钢筋套管。在这一工序当中,套管要满足一下两个方面的条件:1)安装在墙壁内的套管,它的两端应该和墙饰面保持平行,这样做的主要作用就是保证管道在胀缩的时候不受到影响。同时,如果地面发生积水现象,这样就不至于流到下层;2)安装在楼板内的套管,底部应该和楼板的底部平行,顶部要高出地面15—20厘米。2室内采暖管道的安装步骤2.1室内采暖总管的安装室内采暖管道以入口阀门或建筑物外墙一米半为界。
