一、实验室仪器不锈钢管道安装技术要求

1、气瓶(ping)间

①气瓶间应采用300mm以(yi)上(shang)钢筋混凝土防(fang)爆墙，遮阳防(fang)晒，并安装防(fang)爆门，泄露窗。

②室(shi)(shi)内(nei)地(di)面应有防火(huo)花、防静(jing)电(dian)措施；室(shi)(shi)内(nei)电(dian)气设备应具备防爆功能。

③通风良(liang)好，室内(nei)应安装(zhuang)排气扇。

④可燃气体钢瓶（氢(qing)气、乙炔）与助燃气体（氧气）应隔开放置。

⑤气瓶间要(yao)设(she)置报警系统

2、工作间

①所(suo)有管道(dao)要统筹规划、集(ji)中布置、方便(bian)安装、便(bian)于操作、检修(xiu)方便(bian)。

②所(suo)有工(gong)艺管道(dao)要设(she)置切断阀，并根(gen)据需要设(she)置压力表、温(wen)度(du)计、流(liu)量计、过(guo)滤器和减压阀，阀门和仪表要设(she)置在(zai)便于观察和检(jian)修(xiu)的地方。

③可燃气体(ti)管(guan)道要沿墙(qiang)明(ming)线铺设，方便安装和检修。

④使(shi)用钢瓶气管(guan)道(dao)的(de)设备台应离墙布置，且留出不小于600mm的(de)检修空间。

⑤氢气管(guan)道应采用焊接(jie)(jie)连接(jie)(jie)，不能采用螺纹连接(jie)(jie)和(he)使用闸阀。

⑥供(gong)气系统采用二级(ji)减压(ya)方(fang)式进行供(gong)气，气体由15Mpa减到1.5Mpa后再输入到各实验室。

二、用材

1、管(guan)道、球阀(fa)、三通和卡套(tao)均采用316L不(bu)锈钢，高压软管(guan)为不(bu)锈钢波纹(wen)管(guan)，在(zai)高压软管(guan)的(de)进气端配置(zhi)单向阀(fa)，防止更换气瓶时(shi)，软管(guan)内的(de)气体(ti)外(wai)泄，又可防止外(wai)界的(de)空气混入气路中，影响气体(ti)纯度。

2、管道(dao)系(xi)统：所有(you)(you)气体管道(dao)均(jun)采用B*别316L不锈(xiu)钢管，在管路(lu)上(shang)有(you)(you)过滤杂质和水(shui)分的装置(zhi)。

3、管道的(de)连接：汇排流(liu)、终(zhong)端均采(cai)用(yong)卡套连接，便于(yu)减(jian)压器和阀门的(de)维护管理。

4、终(zhong)端(duan)：在每台仪器之前(qian)，配置截(jie)止阀(fa)和(he)二级减压器，截(jie)止阀(fa)控制每个气路的开启(qi)和(he)关(guan)闭(bi)，减压器用于显示(shi)和(he)调(diao)整每个终(zhong)端(duan)的压力。

5、气体(ti)管道每间(jian)隔1.5米采用(yong)管码(ma)支架(jia)固定。

6、整个气路安装完毕后(hou)，对整个系(xi)统做压(ya)(ya)力测(ce)试，压(ya)(ya)力24小(xiao)时(shi)后(hou)无(wu)下降视为(wei)合格(ge)。
