Ukuqinisekisa ukutywinwa kwenkqubo yepayipi yevalvu, ukongeza ekukhetheni izixhobo ezifanelekileyo zokutywina, kuyimfuneko ukufaka i-gasket ngale ndlela ilandelayo ngokuchanekileyo:
I-gasket mayibekwe embindini we-flange, nto leyo ibaluleke kakhulu kwii-flanges zamagxa; ukuqinisekisa ukuba umphezulu wokutywina uthambile kwaye uyachaneka; ii-bolts ezidibanisayo maziqiniswe ngokulinganayo nangokulinganayo; ukusetyenziswa kwee-metal washers kufuneka kuqinisekiswe ukuba umthwalo uyafana kwaye uqinile. Sebenzisa i-torque wrench xa ubopha; jonga kwaye ulinganise kwakhona i-torque ye-bolt edibanisayo emva kokuba inkqubo ye-valve piping isebenze umjikelo omnye; ukuqinisekisa ubomi benkonzo ye-gasket, nceda ungasebenzisi ii-anti-sticking agents okanye ii-lubricants ze-liquid okanye ze-metal matrix.
