API 5L GR.BʻO ka paipu kila maʻemaʻe kahi mea nui i hoʻohana nui ʻia i ka ʻaila a me nā ʻōnaehana pipeline kūlohelohe. Loaʻa iā ia nā waiwai mechanical maikaʻi, ke kūpaʻa corrosion a me ka hilinaʻi, no laila ua makemake ʻia e ka hapa nui o nā mea hoʻohana.
Ma lalo nei, e hoʻolauna mākou i nā ʻano, nā wahi noi a me nā kaʻina hana oAPI 5L GR.Bpaipu kila maʻemaʻe. Hua'ōlelo kiko'ī: waho anawaena 21.3mm ~ 762mm, pā mānoanoa 2.0 ~ 140mm Production hana: wela olokaʻi, anu kiʻi, wela hoʻonui, haawi kūlana: wela olokaʻa, wela lapaʻau.
Nā hiʻohiʻona oAPI 5L GR.BʻO ka paipu kila maʻemaʻe 1. Ka ikaika kiʻekiʻe: API 5L GR.B paipu kila maʻemaʻe i hanaʻia i ke kila kalapona kalapona kiʻekiʻe, me ka ikaika kiʻekiʻe a me ka ikaika tensile, a hiki ke pale i ka nui a me ka ukana. 2. ʻO ka plasticity maikaʻi: ʻO ka paipu kila he plasticity maikaʻi i ka lumi wela, a hiki ke maʻalahi i ka hana ʻana ma ke kuʻi ʻana, wili a me nā hana hana ʻē aʻe. 3. Ke kū'ē'ā'ī: API 5L GR.B paipu kila maʻemaʻeʻole ua hanaʻia ka lāʻau anti-corrosion kūikawā, maikaʻi ke kū'ēʻana i kaʻino, a hiki ke kū'ē pono i kaʻinoʻana o nāʻano media corrosive. 4. ʻO ka hilinaʻi kiʻekiʻe: Ke hoʻokō nei ka paipu kila i ka mana koʻikoʻi i ka wā o ka hana hana e hōʻoia i kēlā me kēia paipu kila i nā koi maʻamau a loaʻa ka hilinaʻi kiʻekiʻe loa.
Nā wahi noi o API 5L GR.B paipu kila ʻoleAPI 5L GR.BHoʻohana nui ʻia ka paipu kila ʻole i ka ʻaila a me nā ʻōnaehana pipeline kūlohelohe. I ka wā o ka ʻimi ʻana i ka aila, ka mining, ka hoʻoili ʻana a me ka lawe ʻana, hiki i ka paipu kila ke kū i nā wahi paʻakikī e like me ke kiʻekiʻe kiʻekiʻe, ke kaomi kiʻekiʻe a me ka corrosion e hōʻoia i ka lawe ʻana i ka ʻaila a me ke kinoea kūlohelohe. Eia kekahi, hoʻohana nui ʻia ia i nā ʻōnaehana kaʻa wai i ka kemika, ka mana uila, ka mālama wai a me nā ʻoihana ʻē aʻe.
