11. Manufacturing process:
- Iyo pombi inogadzirwa uchishandisa inotonhora-yakaumbwa uye yakakwirira-frequency induction welded (HFIW) maitiro.
- Iyo tambo inoumbwa kuita tubular chimiro uye yakakwenenzverwa kureba uchishandisa yakakwirira-frequency induction welding.
12. Kuongorora uye Kuedzwa:
- Kemikari kuongororwa kwezvinhu zvakasvibiswa
- Transverse tensile bvunzo kuti ive nechokwadi chemichini zvivakwa zvinoenderana nezvakatemwa
-Kudzika bvunzo kuti ive nechokwadi chekugona kwepombi kumira deformation
- Root bend bvunzo (yemagetsi fusion welds) kuve nechokwadi chekushanduka kwepombi uye kutendeseka.
- Hydrostatic bvunzo kuti ive nechokwadi chepombi yekuvuza-kusimba

20.Kushivirira:
-Kunze Diameter
-Wall ukobvu
Ukobvu hwemadziro hwepombi hucha, zvichienderana nekushivirira kwe +10 % kana -8 %, huve humwe hwehukoshi hwakakodzera hwakapihwa mukoramu 3 kusvika ku6 yetafura iri pazasi, kunze kwekunge kwakabvumiranwa neimwe nzira pakati pemugadziri nemutengi.
-Kutwasuka
Chero kukanganisa kwepombi kubva kumutsara wakatwasuka, hakufaniri kudarika 0,2 % yehurefu hwepombi.
Chero kunze-kwe-kutenderera (kunze kweiyo yakakonzerwa nesag), yepombi dzekunze kwedhayamita yakakura kupfuura 500 mm haifanire kudarika 1% yedhayamita yekunze (inonzi ovality 2%) kana 6 mm, chero idiki.
Ndokumbira utarise kuti iyi yakadzama data sheet inopa ruzivo rwakakwana nezveSANS 719 Grade C mapaipi.Zvakananga zvinodikanwa zvinogona kusiyana zvichienderana neprojekti uye chaiyo chaiyo yepombi inodiwa.
