一、云南昆明冶研新材料实验室分析(xi)仪器管路安装技术要求

1、气瓶间

①气瓶间(jian)应采用300mm以上钢筋混凝土(tu)防(fang)爆墙，遮阳防(fang)晒，并安装防(fang)爆门(men)，泄露窗。

②室(shi)(shi)内地面应有(you)防(fang)火花(hua)、防(fang)静电措施；室(shi)(shi)内电气设备应具备防(fang)爆功能。

③通风(feng)良好，室内应安装(zhuang)排(pai)气扇。

④可燃气体(ti)钢瓶（氢气、乙炔(gui)）与助燃气体(ti)（氧(yang)气）应隔开放(fang)置(zhi)。

⑤气瓶间要设(she)置(zhi)报警(jing)系统

2、工作间

①所有管道要统筹规划、集中布置(zhi)、方(fang)便(bian)安装、便(bian)于操作、检(jian)修方(fang)便(bian)。

②所有工艺(yi)管道要(yao)设置切断阀，并根据(ju)需(xu)要(yao)设置压力表、温(wen)度(du)计(ji)、流量计(ji)、过滤器(qi)和(he)减压阀，阀门和(he)仪表要(yao)设置在便于(yu)观察(cha)和(he)检修的地方。

③可燃气体管(guan)道要沿墙明线(xian)铺设，方便安装(zhuang)和检修。

④使用钢瓶(ping)气管道的(de)设备台应(ying)离墙布置(zhi)，且留出不(bu)小(xiao)于600mm的(de)检(jian)修空(kong)间。

⑤氢气(qi)管(guan)道应采(cai)用焊接连接，不能(neng)采(cai)用螺纹(wen)连接和使用闸(zha)阀。

⑥供气(qi)系统(tong)采用二级减压方式进行(xing)供气(qi)，气(qi)体由15Mpa减到1.5Mpa后(hou)再输入(ru)到各实验室。

二、用材(cai)

1、管(guan)道(dao)、球阀、三通(tong)和卡套均采用316L不(bu)锈钢，高压软管(guan)为(wei)不(bu)锈钢波纹管(guan)，在高压软管(guan)的进气(qi)(qi)端(duan)配(pei)置单向阀，防(fang)(fang)止(zhi)更换气(qi)(qi)瓶时，软管(guan)内的气(qi)(qi)体外泄，又可防(fang)(fang)止(zhi)外界的空气(qi)(qi)混(hun)入气(qi)(qi)路中，影响(xiang)气(qi)(qi)体纯度。

2、管道系(xi)统(tong)：所有气(qi)体管道均采用(yong)B*别316L不锈(xiu)钢(gang)管，在管路上有过滤杂质和(he)水分(fen)的装置。

3、管(guan)道的连接：汇(hui)排(pai)流、终端(duan)均采(cai)用卡套连接，便(bian)于减压器和(he)阀门(men)的维(wei)护管(guan)理。

4、终(zhong)端：在每(mei)(mei)台仪器(qi)之前，配置截止阀(fa)和二级减(jian)压器(qi)，截止阀(fa)控(kong)制每(mei)(mei)个(ge)(ge)气路(lu)的(de)开启(qi)和关(guan)闭，减(jian)压器(qi)用于显示和调整每(mei)(mei)个(ge)(ge)终(zhong)端的(de)压力(li)。

5、气体管道每间隔1.5米采用管码支(zhi)架固定。

6、整(zheng)个气路(lu)安装完毕(bi)后，对(dui)整(zheng)个系统(tong)做压(ya)力测试，压(ya)力24小时后无下(xia)降视为合(he)格。
