Izindololwane zensimbi engagqwaliziyizingxenye ezibalulekile ezinhlelweni zamapayipi ezihlukahlukene, ezihlinzeka ngokuguquguquka nokuqina ekuqondiseni ukugeleza koketshezi namagesi. Lezi zindololwane zisetshenziswa kakhulu ku-petrochemical, uwoyela negesi, ukucubungula ukudla, izimboni zemithi nezinye. Kodwa-ke, ukuze kuqinisekiswe ikhwalithi nokuthembeka kwezindololwane zensimbi engagqwali, kubalulekile ukuqonda izindinganiso ezilawula ukukhiqizwa nokusetshenziswa kwazo.
Izindinganiso zezindololwane zensimbi engagqwali zinqunywa ngokuyinhloko ngokucaciswa kwezinto ezibonakalayo, ubukhulu kanye nezinqubo zokukhiqiza. Izinga elivame ukucashunwa ezindololwaneni zensimbi engagqwali yizinga le-ASME B16.9. Leli zinga licacisa ubukhulu, ukubekezelela kanye nezinto zokwakha zendololwane zensimbi engagqwali ezisetshenziswa ekusetshenzisweni komfutho ophezulu kanye nezinga lokushisa eliphezulu.
Ngokwezindinganiso ze-ASME B16.9, izindololwane zensimbi engagqwali zitholakala ngosayizi abahlukahlukene ukusuka ku-1/2 intshi ukuya ku-48 amayintshi, anama-engeli ahlukene afana nama-degree angu-45, 90 degrees, kanye nama-degree angu-180. Izinga liphinde lichaze ukubekezelela okuvumelekile kobukhulu bendololwane, liqinisekisa ukuthi liyahlangabezana nezicaciso ezidingekayo ekwakhiweni okungenamthungo nokushiselwe.
Ngokungeziwe kumazinga e-ASME B16.9, izindololwane zensimbi engagqwali zingenziwa futhi zihlolwe kwamanye amazinga omhlaba afana ne-ASTM, i-DIN, ne-JIS, kuye ngezidingo ezithile zohlelo lokusebenza nendawo yephrojekthi.
Ngokuqondene nokucaciswa kwezinto ezibonakalayo, izindololwane zensimbi engagqwali ngokuvamile zenziwe nge-austeniticinsimbi engagqwaliamabanga afana no-304, 304L, 316 kanye no-316L. Lawa mabanga anikeza ukumelana nokugqwala okuhle kakhulu, amandla aphezulu kanye nokushisela okuhle, okuwenza afanelekele uhla olubanzi lwezicelo zezimboni.
Inqubo yokukhiqiza izindololwane zensimbi engagqwali nayo ilawulwa yizindinganiso zokuqinisekisa ikhwalithi nobuqotho bomkhiqizo wokugcina. Izinqubo ezifana ne-thermoforming, ukwakheka okubandayo kanye nokwenza imishini kufanele kuhambisane nezindinganiso ukuze kugcinwe izakhiwo zemishini kanye nokunemba kobukhulu bendololwane.
Mayelana nokuhlola nokuhlola, izindololwane zensimbi engagqwali kufanele zihlolwe okuhlukahlukene okungacekeleki phansi nokulimazayo ukuze kuqinisekiswe izinga nokusebenza kwazo. Kuye ngezindinganiso ezifanele, lezi zivivinyo zingase zihlanganise ukuhlola okubonakalayo, ukuhlolwa kobukhulu, ukuhlolwa kokungena kodayi, ukuhlolwa kwe-radiographic kanye nokuhlolwa kwe-hydrostatic.
Kubalulekile kubakhiqizi, abahlinzeki kanye nabasebenzisi bokugcina ukuthi baqonde izidingo ezijwayelekile zezindololwane zensimbi engagqwali ukuze kuqinisekiswe ukuthi umkhiqizo uhlangabezana nekhwalithi edingekayo kanye namazinga okuphepha. Ukuthobelana nalawa mazinga akuqinisekisi nje kuphela ukwethembeka nokusebenza kwendololwane, kodwa futhi kusiza ukuthuthukisa ubuqotho buphelele besistimu yamapayipi lapho kusetshenziswa indololwane.
Ukufingqa, amazinga ezindololwane zensimbi engagqwali ahlanganisa izici ezahlukahlukene njengokucaciswa kwezinto ezibonakalayo, ubukhulu, izinqubo zokukhiqiza, kanye nezidingo zokuhlola. Ngokuqonda nokunamathela kulawa mazinga, ababambiqhaza bemboni bangaqinisekisa ikhwalithi, ukwethembeka nokuphepha kwezindololwane zensimbi engagqwali ekusetshenzisweni kwazo. Kungakhathaliseki ukuthi kuyinqubo ebucayi embonini yamakhemikhali noma ukusetshenziswa kwenhlanzeko embonini yokudla, izindinganiso zendololwane zensimbi engenasici zidlala indima ebalulekile ekugcineni ukusebenza kahle nobuqotho besistimu yakho yamapayipi.
