Hydrostatic test
Pipe yekumira kuyedza hydrostatic pasina kuvuza kuburikidza nemusono we weld kana muviri wepombi. Majoini haafanire kuongororwa hydrostatic kupa zvikamu zvepombi zvakashandiswa zvakaedzwa zvakabudirira.

Hapana kuputika kuchaitika mune chero chikamu cheyedzo chidimbu uye hapana kuvhurwa kweweld kuchaitika.
Flattening bvunzo
Maitiro ekugamuchirwa ekuyedzerwa flattening achave:
- EW mapaipi D<12.750 mu:
- X60 ine T 500in. Pachave pasina kuvhurwa kweweld chinhambwe chiri pakati pemahwendefa chisati chasvika 66% yedhayamita yepakutanga yekunze. Kune ese mamakisi uye madziro, 50%.
- Kune pombi ine D/t> 10, hapazovi nekuvhurwa kweweld isati yasvika kureba pakati pemaplateti isingasviki 30% yepakutanga dhayamita yekunze.
- Kune mamwe saizi tarisa kune yakazara API 5L yakatarwa.
CVN kukanganisa bvunzo yePSL2
Mazhinji PSL2 pombi saizi uye mamakisi zvinoda CVN. Seamless pombi inofanirwa kuongororwa mumuviri. Welded pombi inofanirwa kuyedzwa mumuviri, pombi weld uye nzvimbo yakakanganiswa nekupisa. Tarisa kune yakazara API 5L yakatarwa yechati yehukuru uye mamakisi uye inodiwa yakanyudzwa simba kukosha.
