Wonke amapayipi ensimbi ekhabhoni asetshenziswa emazingeni okushisa aphansi (ngaphansi kuka-20°C) kufanele asebenzise indinganiso ye-GB6479, ecacisa kuphela izidingo zokuqina komthelela ophansi kwezinga lokushisa kwezinto.

GB3087futhiGB5310izindinganiso ziyizindinganiso ezibekwe ngokukhethekile kumapayipi ensimbi okubhayela. “Imithetho Yokulawula Ukuphepha Kwamabhoyili” igcizelela ukuthi wonke amapayipi axhunywe kumabhoyili angaphakathi kwendawo yokugadwa, futhi ukusetshenziswa kwezinto zawo kanye namazinga kufanele kuhambisane “neMithetho Yokulawula Ukuphepha Kwebhoyili”. Ngakho-ke, ama-boilers, izitshalo zamandla, ukushisisa kanye nemishini yokukhiqiza ye-petrochemical isebenzisa Amapayipi omusi womphakathi (ahlinzekwa uhlelo) kufanele asebenzise amazinga e-GB3087 noma e-GB5310.

Kuyaphawuleka ukuthi intengo yamapayipi ensimbi anezinga elihle lekhwalithi yensimbi yepayipi izindinganiso nayo iphakeme kakhulu. Isibonelo, intengo ye-GB9948 icishe iphakame ngo-1/5 kunaleyo yezinto zokwakha ze-GB8163. Ngakho-ke, lapho ukhetha izindinganiso zezinto ezibonakalayo zamapayipi ensimbi, kufanele kucatshangelwe ngokucophelela ngokuya ngemibandela yokusetshenziswa. Kumele kube okuthembekile futhi okuthembekile. Ukuze kube ukonga. Kufanele futhi kuqashelwe ukuthi amapayipi ensimbi ngokwe-GB/T20801 kanye ne-TSGD0001, GB3087 kanye namazinga e-GB8163 ngeke asetshenziselwe amapayipi e-GC1 (ngaphandle uma nge-ultrasonically, ikhwalithi ayikho ngaphansi kwezinga le-L2.5, futhi ingasetshenziselwa i-GC1 ngokuklama umfutho ongemkhulu kunepayipi elingu-4.0Mpa (1).
