API 5L GREYIDI B POMBI

Tsananguro pfupi:

Zita: API 5L Giredhi B Pombi

API 5L ndiyo inonyanya kufarirwa pakushandisa mapaipi emugero yakagadzirwa neAmercian Petroleum Institute. Panguva imwe chete, ISO3183 neGB/T 9711 ndiwo mwero wepasi rose uye mwero weChinese wekushandisa mapaipi emugero zvakasiyana. Tinogona kugadzira mapaipi emugero zvichienderana nemwero mitatu yataurwa.
