Kuchotsa Mgwirizanos amatenga gawo lalikulu pakupanga ndi kusanja mapaipi ndi ma valve.Ndi chithandizo chofunikira panthawi yoyika ndi kuchotsa zigawo za chitoliro ndi ma valve.Popanda cholumikizira cholumikizira chopereka kusintha kwautali, ndizosatheka kuyika valavu ndendende mu gawo la chitoliro.Chifukwa cha kusinthika kwa mgwirizano wosweka, valavu imatha kuikidwa pafupi ndi cholumikizira chophwanyika, ndipo cholumikiziracho chikhoza kukhazikitsidwa kutalika kwake komwe kumafunikira musanalumikizidwa bwino ndi ma flanges.

Kutsatizana kwa m'mbuyo kumagwiritsidwa ntchito pochotsa, pomwe kukonzanso kutalika kwa cholumikizira kumapanga mpata wokwanira kumasula ndi kuchotsa valavu.Pazochitika zonsezi, cholumikizira chimatsimikizira kukhazikitsidwa ndi kuchotsedwa mwachangu, motero kumathandizira kuti pakhale magwiridwe antchito komanso kuchepetsa magwiridwe antchito komanso nthawi yocheperako.Ndondomekoyi ndi yofanana pamene zigawo za mapaipi ziyenera kulumikizidwa pamodzi.Mitundu ina ya zolumikizira zolumikizira ndizoyeneranso kugwiritsidwa ntchito popanda kuletsa mapaipi osinthika.Pomaliza, kuthyola mafupa atha kugwiritsidwa ntchito kudzaza mipata mwachitsanzo, pomwe pampu yoyikidwa pamalo okhazikika iyenera kulumikizidwa ndi chitoliro chotuluka pakhoma.

Ubwino wa dismanting olowa
1.Kuyika ndi kosavuta komanso kosavuta, kuyika ma valve osavuta.
2.Rubber ndi yolimba mu kukanikiza ndi elasticity.
3.Metal ndi mphete zosindikizira ndizolimba kwambiri.
4.Papaipi, imatha kubweza bwino ndikuchepetsa chitoliro ndi kukankhira kwa mbale.
