浙江至德(de)鋼業有(you)限公司在參加某球(qiu)罐(guan)(guan)(guan)(guan)(guan)配(pei)管設計(ji)評(ping)審時,發(fa)現(xian)有(you)的球(qiu)罐(guan)(guan)(guan)(guan)(guan)的連(lian)(lian)(lian)接(jie)(jie)(jie)(jie)管道也(ye)增(zeng)加金屬軟管連(lian)(lian)(lian)接(jie)(jie)(jie)(jie)。而(er)球(qiu)罐(guan)(guan)(guan)(guan)(guan)支(zhi)柱位置通常經過(guo)打(da)樁處(chu)理,球(qiu)罐(guan)(guan)(guan)(guan)(guan)的整(zheng)體沉降量較少,球(qiu)罐(guan)(guan)(guan)(guan)(guan)的操作壓力較大,球(qiu)罐(guan)(guan)(guan)(guan)(guan)口連(lian)(lian)(lian)接(jie)(jie)(jie)(jie)管線一般不需加金屬軟管等柔性連(lian)(lian)(lian)接(jie)(jie)(jie)(jie)件,但是,球(qiu)罐(guan)(guan)(guan)(guan)(guan)的連(lian)(lian)(lian)接(jie)(jie)(jie)(jie)管線的配(pei)管設計(ji)需要保證合(he)適的柔性。
以下(xia)規范和(he)規定(ding)可作為配管設(she)計參考(kao)依據:
SH 3136《液化(hua)烴(jing)球形儲罐(guan)(guan)安(an)全設計規(gui)范》規(gui)定:接(jie)在(zai)液化(hua)烴(jing)球形儲罐(guan)(guan)上的管(guan)道應(ying)考慮支撐的措施,考慮到大型球形儲罐(guan)(guan)可(ke)能存在(zai)地基的不(bu)均(jun)勻沉降(jiang),所以與其連接(jie)的管(guan)道應(ying)有一定的撓性(xing)。
中石化《液化烴球罐緊急切斷閥選型設計規定》要求:從緊急切斷閥到球罐管口之間除了接管外不得安裝其他管件或閥門。
