Dhayamita yezita uye dhayamita yemukati nekunze yepombi yesimbi inotenderera

Pipe yesimbi inotendereraimhando yepombi yesimbi inogadzirwa nekumonera simbi kuita shape yepombi pakona imwe chete (forming angle) wozoibatanidza. Inoshandiswa zvakanyanya mumapaipi ekufambisa mafuta, gasi rechisikigo uye mvura.

Dhayamita yepakati ndiyo dhayamita yepakati yepombi, kukosha kwepakati kwehukuru hwepombi. Papombi yesimbi inotenderera, dhayamita yepakati inowanzova pedyo, asi isingaenzane, nedhayamita chaiyo yemukati kana yekunze.

Kazhinji inoburitswa neDN pamwe nenhamba, yakaita seDN200, iyo inoratidza pombi yesimbi ine dhayamita ye200 mm.

Dhayamita yekunze (OD): OD dhayamita yekunze kwepombi yesimbi inotenderera. OD yepombi yesimbi inotenderera ndiyo saizi chaiyo yekunze kwepombi. OD inogona kuwanikwa nekuyera chaiko, kazhinji mumamirimita (mm).
Dhayamita Yemukati (ID): ID ndiyo dhayamita yemukati mepombi yesimbi inotenderera. ID ndiyo saizi chaiyo yemukati mepombi. ID inowanzo verengerwa nekubvisa kaviri ukobvu hwemadziro kubva kuOD mumamirimita (mm) ID = OD-2 x Ukobvu hwemadziro

Munda wekushandisa

Mapaipi esimbi anotenderera ane dhayamita dzakasiyana ane mashandisirwo akasiyana muminda yakasiyana:
1. dhayamita dikiSsaw Steel Pipe(DN100 - DN300): inowanzoshandiswa muinjiniya yemaguta pakugadzira mapaipi emvura, mapaipi emvura, mapaipi egasi, nezvimwewo.
2. dhayamita yepakatiPombi yeSsaw(DN350 - DN700): inoshandiswa zvakanyanya mumafuta, mapombi egasi rechisikigo uye mapaipi emvura emaindasitiri. 3. pombi yesimbi inotenderera ine dhayamita hombe (DN100 - DN300): inowanzoshandiswa mumapaipi emvura einjiniya yemaguta, mapaipi emvura, mapaipi egasi, nezvimwewo.
3.Dhayamita Yakakura yeSsaw Pipe(DN750 - DN1200): inoshandiswa mumapurojekiti ekufambisa mvura kure, mapaipi emafuta, mapurojekiti makuru emaindasitiri, akadai sekufambisa kwepakati nepakati.
4. dhayamita yakakura kwazvoSsaw Carbon Steel Pipe(DN1300 zvichikwira): inonyanya kushandiswa kumapurojekiti emapaipi emvura, mafuta negasi anoyambuka dunhu, mapaipi epasi pemvura nemamwe mapurojekiti makuru ezvivakwa.

Dhayamita yezita uye zvimwe zvinotsanangurwa zvepombi yesimbi inotenderera zvinowanzogadzirwa zvichienderana nezvinodiwa uye zvinotsanangurwa:
1. zviyero zvepasi rose: API 5L: inoshanda papombi yesimbi yekufambisa mapaipi, inotsanangura saizi nezvinodiwa nezvinhu zvepombi yesimbi inotenderera ASTM A252: inoshanda papombi yesimbi yekuvaka, inotsanangura saizi nezvinodiwa zvekugadzira pombi yesimbi inotenderera.
2. mwero wenyika: GB/T 9711: inoshanda papombi yesimbi yekufambisa mafuta negesi, inotsanangura zvinodiwa zvehunyanzvi zvepombi yesimbi inotenderera. gb/t 3091: inoshanda papombi yesimbi yakasungirirwa yekufambisa mvura ine simba shoma, inotsanangura saizi uye zvinodiwa zvehunyanzvi zvepombi yesimbi inotenderera.
