Zvinotora basa rakawanda kugadzira butt welding flanges, uye nekuti hombe butt welding flanges dzine mitengo yakakwira yekugadzira, preheating inowanzodikanwa. Iyo deformation yezvakagadzirwa uye deformation maitiro ane hukama nekushisa uye mekiniki maitiro eiyo masvomhu modhi inozivikanwa sekombuta simulation flange. Iyi deformation process inoitwa nerubatsiro rwekombuta simulation chero nguva kana mamiriro ekushushikana, kunetsa, uye kugovera tembiricha iripo. Kombuta yemuviri simulation uye maitiro simulation anogona kutsigira uye kuwedzera mumwe nemumwe. Mabutt welding flanges ane basa guru kugadzira, uye preheating inowanzodiwa nekuda kwekudhura kwakanyanya kwekugadzira mabutt welding flanges. Komputa simulation flange ishoko rinoshandiswa kutsanangura kuti mbishi zvinhu zvinokanganisa sei pamwe nekukanganisa kwe tembiricha uye michina yemhando yemasvomhu. Simulation yekombuta inoshandiswa kuita iyi deformation process pese panosangana mamiriro ekushushikana, kunetsa, uye tembiricha. Computerized process simulation uye kuenzanisa kwemuviri zvinogona kubatsirikana kubva uye kuzadzisana.
IEuropean pipe flange system, iyo inosanganisira yaimbova Soviet Union, inomiririrwa neGermany DIN, uye American pipe flange system inomiririrwa neAmerican ANSI pipe flange. Aya maitiro maviri ndiwo makuru anoshandiswa pasi rose. Japanese JIS chubhu flanges imwe sarudzo, kunyange zvazvo simba ravo repasi rose rakaderera nekuti rinowanzo shandiswa kumabasa eruzhinji munzvimbo dzepetrochemical. Izvi zvinotevera mhedziso yekutanga yepombi flanges inoshandiswa munyika imwe neimwe:
1.Germany neyaimbova Soviet Union inhengo mbiri dzeEuropean system framework.
2.The ANSI B16.5 uye ANSI B 16.47 American system pombi flange zviyero
3.Kune akaparadzana casing flange zviyero kune nyika mbiri 'yakasiyana pombi flanges.
Mukupedzisa, iyo miviri yakasiyana uye isingachinjiki pombi flange masisitimu ayo anoumba mwero wepasi rose wepombi flanges ndeaya anotevera: European pipe flange system, inomiririrwa neGermany; uye American pipe flange system, inomiririrwa neUnited States.
Sangano reInternational Organisation for Standardization rakaburitsa mwero wepombi flange unozivikanwa seIOS7005-1 muna 1992. Chiyero ichi chinosanganisa mwero wepombi flange kubva kuGermany neUnited States.
