Overview
Pipeline simbi ndiro inoshandiswa kugadzira mapaipi makuru akaiswa dhayamita anotakura oiri uye gasi rechisikigo, zvakare zita rekuti pombi simbi ndiro. Iye zvino vanhu vakawanda pasi rose vari kutarisa nezvekuchengetedza zvakatipoteredza, gasi idzva resimba rakachena rinoshandiswa zvakanyanya kuburikidza nemapaipi. Aya mapaipi esimbi maplate ane kugona kurwisa kudzvanywa kwepamusoro, corrosion yemhepo uye tembiricha yakadzikira. API X120 yakapihwa kubva kwatiri yaive yakakwira michina zvivakwa kupfuura nhanho yepasirese.
