Inotungamira Simbi Mapaipi Mugadziri & Mutengesi MuChina |

Tube uye Pipe Indasitiri Yakajairika Mapfupi / Matemu

Mukati meiyi ndima yesimbi, mune yakatarwa seti yeacronyms uye terminology, uye iyi yakasarudzika terminology ndiyo kiyi yekutaurirana mukati meindasitiri uye hwaro hwekunzwisisa nekuita mapurojekiti.

Muchinyorwa chino, tichakuzivisa iwe kune anonyanya kushandiswa simbi pombi uye tubing indasitiri acronyms uye mazwi, kubva kune yakakosha ASTM zviyero kusvika kune yakaoma zvinhu zvivakwa, uye isu tichazvitsanangura chimwe nechimwe kukubatsira iwe kuvaka chimiro che ruzivo rweindasitiri.
