Iyo Screwed kana Threaded flanges inoshandiswa pamitsetse yepombi apo welding haigone kuitwa. Mupendero wakarukwa kana kufitwa haukodzere pombi ine mudhuri wakatetepa, nekuti shinda yekucheka papombi haigoneki.Saka, kukobvu kwemadziro kunofanira kusarudzwa.ASME B31.3 Piping Guide inoti:Panorukwa pombi yesimbi uye inoshandiswa kuita chiutsi chinodarika 250 psi kana sevhisi yemvura inopfuura 100 psi ine tembiricha yemvura inodarika 220°F, iko kukora kwepaipi kunenge kwakaenzana kusvika 80 F, hurongwa hwepombi hunenge husina kuenzana ne220°F.
