注意事项： 1、做好防火管理；检修时管道内不能形成富氧空气。 2、加强油脂管理，检修时管道内不能留下油污。 3、加强设备的维护管理工作，杜绝设备带病运行。 4、加强压力容器管理，杜绝超温、超压、超负荷运行。

氧气管道安装注意的事项：1. 暖气管道材质，主要有铝塑管、PPR管和PB管。（1）铝塑管保温性好、外壁不易被腐蚀，内壁光滑，从而对水流阻力小，并且可以随意弯曲，故方便施工，同时性价比也比较高。（2）PPR管耐腐蚀、耐热性好、质量轻、机械强度高、不易结垢，使用寿命长。并且现在市场上有PPR铝塑管，同时结合了PPR管和铝塑管的优点。（3）PB管是一种高分子惰性聚合物，具有耐高温性、持久性、化学稳定性、可塑性、无味、无臭、无毒，不结垢、寿命长等特性，但是PB管的氧气渗透率比较高，需要阻氧。目前市场上都是阻氧PB管。暖气片的学名叫做采暖散热器，是冬季采暖最佳的方式之一，由于采暖系统的水压一般都在0.4MPa 以上，如果安装不好，一旦漏水，将损失惨重，因此暖气片的安装与暖气片的质量一样十分重要。从安装美观、确保安全方面进行考虑，暖气片的安装应按照以下步骤进行。第一步：先与暖气片销售商的技术人员一起进行实地测量设计，确定暖气片的型号、片数、进出水方式和具体的安装位置，技术员根据实际情况并与业主沟通，确定暖气片的型号、组数、每组片数和安装位置等，并与销售商签订暖气片购销合同；第二步：与暖气片施工单位签订施工协议，以确保施工质量和风险，一般施工单位要在施工协议上注明，暖气系统的施工至少要质保一个采暖季。如果暖气片销售单位和施工单位为同一个单位势最好。第三步：暖气片安装的一期工程施工。暖气片的安装分为两个步骤：一期工程和二期工程。暖气一期工程包括暖气设备的*、开槽、布管（或改管道）、管道连接（焊管）、集分水器的安装、打压测试等；二期工程包括：暖气片的安装（暖气片的固定悬挂、阀门与暖气片和供暖管的连接）、整个系统加压检测和暖气片的调试等。注意：暖气一期工程施工是在墙壁改造后，水电施工前或施工后并且必须在其他装修工序施工前进行。暖气一期工程没有施工完并经业主验收签字通过前，其他装修工序决不允许施工。需要强调的是，为了美观，如果是在装修前进行的暖气安装，暖气主管与暖气片连接的支管一定要暗埋入地坪下和墙内，与暖气片连接时只能看到温控阀门；现在有不少的暖气工程施工人员为了省事，支管直接从地下漏出地面与暖气片连接，这样每组暖气片都有两根管子漏在外面，不仅不美观而且容易碰坏。

1、强度试验一般采用水压试验.氧气管道试压时,使用的试验介质都应是无油的水压泵也必须除油.如以气压来进行强度试验,应按试验压力的20％分级升压 2、升至所要求的试验压力后,观测5min,如压力不下降,则将压力降至工作压力进行外观检查,无破裂、变形或漏气等情况即认为合格.如以水压来进行试验,升至所要求的试验压力后,观测10min,其余要求同气压试验.3、强度试验合格后再进行严密性试验,试验压力升至规定值时,在所有接口处涂皂液检查,并观测24h,如无缺陷且平均每小时漏气率≤1％为合格.希望我的回答能帮到您
