Iyo Screwed kana Threaded flanges inoshandiswa pamitsetse yepombi apo welding haigone kuitwa. Mupendero wakaiswa shinda kana kufitwa hauna kukodzera pombi ine madziro akatetepa, nekuti shinda yekucheka papombi hazvigoneke. Saka, kukobvu kwemadziro kunofanira kusarudzwa.ASME B31.3 Piping Guide inoti:Pane pombi yesimbi painorukwa uye inoshandiswa kuita chiutsi chinodarika 250 psi kana sevhisi yemvura inopfuura 100 psi ine tembiricha yemvura inodarika 220°F, pombi ichange isina musono uye iine ukobvu hunenge hwakaenzana nehurongwa 80 hweASME B36.10.Socket welding uye threaded flanges hazvisi inokurudzirwa kushanda pamusoro pe250 ° C uye pasi -45 C.
