ʻO ka paipu ASTM A106 Papa B kekahi o nā paipu kila humuhumu kaulana loa i hoʻohana ʻia ma nā ʻoihana like ʻole. ʻAʻole wale i nā ʻōnaehana paipu e like me ka ʻaila a me ke kinoea, ka wai, ka hoʻoili ʻana o ka slurry mineral, akā no ka paila, ke kūkulu ʻana, a me nā kumu kūkulu.
Hoʻolauna huahana
Hoʻohana pinepine ʻia ka ASTM A106 Seamless Pressure Pipe (i ʻike ʻia hoʻi ʻo ka paipu ASME SA106) i ke kūkulu ʻana i nā hale hoʻomaʻemaʻe aila a me ke kinoea, nā mea kanu mana, nā mea kanu petrochemical, nā paila, a me nā moku kahi e pono ai nā paipu e lawe i nā wai a me nā kinoea e hōʻike ana i nā mahana kiʻekiʻe a me nā pae kaomi.

ʻO Jiangsu Hangdong Metal Products Co., Ltd. he lālā ia o Jiangsu Hangdong Iron & Steel Group Co., LTD. He ʻoihana noiʻi a hoʻomohala, hana, kūʻai aku, lawelawe ma kekahi o nā ʻoihana hana metala ʻoihana. 10 mau laina hana. Aia ke keʻena nui ma Wuxi City, Jiangsu Province e like me ka manaʻo hoʻomohala o "lanakila ka maikaʻi i ka honua, hoʻokō ka lawelawe i ka wā e hiki mai ana". Kūpaʻa mākou i ka kaohi maikaʻi a me ka lawelawe noʻonoʻo. Ma hope o nā makahiki he ʻumi o ke kūkulu ʻana a me ka hoʻomohala ʻana, ua lilo mākou i ʻoihana hana metala i hoʻohui ʻia.
