Ka Mana Kūlana Koʻikoʻi:
1) I ka wā a ma hope o ka hana ʻana, 4 mau limahana QC me ka ʻoi aku o 5 mau makahiki o ka ʻike e nānā i nā huahana ma kahi random.
2) Keʻena hoʻokolohua i hōʻoia ʻia e ka ʻāina me nā palapala hōʻoia CNAS
3) Nānā ʻae ʻia mai ka ʻaoʻao ʻekolu i koho ʻia/uku ʻia e ka mea kūʻai, e like me SGS, BV.
4) Ua ʻāpono ʻia e Malekia, ʻInidonesia, Singapore, Pilipine, ʻAukekulelia, Peru a me UK. Loaʻa iā mākou nā palapala hōʻoia UL /FM, ISO9001/18001, FPC
E pili ana iā mākou:
Ua hoʻokumu ʻia ʻo Tianjin Youfa Steel Pipe Group Co., Ltd ma Iulai 1, 2000. Aia ma kahi o 8000 mau limahana, 9 mau hale hana, 179 mau laina hana paipu kila, 3 keʻena hoʻokolohua i hōʻoia ʻia e ka ʻāina, a me 1 kikowaena ʻenehana ʻoihana i hōʻoia ʻia e ke aupuni Tianjin.
