OEM China ASTM A106 / API 5L / ASTM A53 kalasi b opanda zitsulo chitoliro kwa payipi mafuta ndi gasi
Mwachidule
Nthawi zonse timapeza ntchitoyo kudzera pokhala gulu la akatswiri kuti tiwonetsetse kuti titha kukupatsani mwayi wapamwamba kwambiri komanso wothandiza kwambiri. Kwa ASTM A106/ API 5L / ASTM A53 giredi B chitoliro chachitsulo chosasunthika chapaipi yamafuta ndi gasi, tili ndi zaka zopitilira 3 kuti tipereke izi m'machitidwe osiyanasiyana ogwiritsira ntchito. Tidzaona kukhutitsidwa kwamakasitomala monga momwe zimakhalira, tigwiritse ntchito zomwe timapeza kuti tipatse zomwe makasitomala athu amafunikira komanso kuti makasitomala athu azitsika mtengo.
Tikulandira mwachikondi makasitomala apakhomo ndi akunja kuti azichezera kampani yathu ndikukambirana zamalonda. Kampani yathu nthawi zonse imaumirira pa mfundo ya "khalidwe labwino, mtengo wololera, ntchito yapamwamba kwambiri". Takhala okonzeka kupanga mgwirizano wanthawi yayitali, waubwenzi komanso wopindulitsa ndi inu.
Kugwiritsa ntchito
Chitoliro chopanda chitsulo chopanda ntchito cha ASTM A106, choyenera kutentha kwambiri
