Chitoliro cha API 5L GRADE B

Kufotokozera Kwachidule:

Dzina: Chitoliro cha API 5L Giredi B

API 5L ndiye muyezo wotchuka kwambiri wa mapaipi apaipi omwe adapangidwa ndi Amercian Petroleum Institute. Nthawi yomweyo, ISO3183 ndi GB/T 9711 ndi muyezo wapadziko lonse lapansi komanso muyezo waku China wa mapaipi apaipi padera. Titha kupanga mapaipi apaipi motsatira miyezo yonse itatu yomwe yatchulidwa.
