GB8162a ʻo GB8163 ʻelua mau kikoʻī like ʻole no nā paipu kila maʻemaʻe ma nā kūlana aupuni o Kina. Loaʻa iā lākou nā ʻokoʻa nui i ka hoʻohana ʻana, nā koi ʻenehana, nā kūlana nānā, a me nā mea ʻē aʻe.
1. Ka inoa maʻamau a me ka laulā o ka noi
Inoa: "Pipe Steel Seamless for Structural Use"
Hoʻohana: Hoʻohana nui ʻia i nā hale maʻamau, ka hoʻoili ʻana i ka mīkini a me nā kahua kaʻa kaʻa ʻole wai, e like me ke kākoʻo hale, nā ʻāpana mechanical, etc.
Nā hiʻohiʻona kūpono: nā manawa me nā haʻahaʻa static a i ʻole mechanical, ʻaʻole kūpono no ke kaomi kiʻekiʻe a i ʻole ka halihali wai.
Inoa: "Pipe Steel Seamless for Fluid Transportation"
Hoʻohana: Hoʻolālā ʻia no ka lawe ʻana i nā wai (e like me ka wai, ka aila, ke kinoea, a me nā mea ʻē aʻe), i hoʻohana mau ʻia i nā ʻōnaehana pipeline kaomi e like me ka petroleum, kemika, boilers, etc.
Nā hiʻohiʻona kūpono: Pono e kū i kekahi mau pilikia a me nā mahana, a loaʻa nā koi palekana kiʻekiʻe
2. Nā mea a me nā mea hana kemika
GB8162:
Mea maʻamau:20#, 45#, Q345Ba me nā kila kalapona maʻamau a i ʻole nā kila hao haʻahaʻa.
ʻO nā koi hoʻohui kemika he mea wehe, e kālele ana i nā waiwai mechanical (e like me ka ikaika tensile, ka ikaika hua).
GB8163:
ʻO nā mea maʻamau: 20 #, 16Mn, Q345B, a me nā mea ʻē aʻe, pono e hōʻoia i ka weldability maikaʻi a me ke kūpaʻa paʻa.
ʻO ka ʻike o nā mea ʻino e like me ka sulfur (S) a me ka phosphorus (P) ʻoi aku ka paʻa o ka mālama ʻana i ka palekana o ka lawe wai.
3. Nā koi hana mīkini
GB8162:
Hoʻopili i nā waiwai mechanical e like me ka ikaika tensile a me ka elongation e hoʻokō i nā koi o ka halihali ukana.
ʻAʻole koi pinepine ʻia nā hoʻokolohua hoʻokō wela wela a i ʻole ka paʻakikī.
GB8163:
Ma waho aʻe o ka ikaika tensile, nā hoʻāʻo ʻana i ka wai, nā hoʻāʻo hoʻonui, nā hoʻāʻo hoʻopalapala, a me nā mea ʻē aʻe e koi ʻia e hōʻoia i ka leakage a i ʻole deformation o ka paipu kila ma lalo o ke kaomi.
Pono kekahi mau kūlana hana i ka hana wela kiʻekiʻe a i ʻole nā hoʻokolohua hopena haʻahaʻa.
4. Ho'āʻo kaomi
GB8162:
ʻAʻole koi ʻia ka hoʻāʻo ʻana i ke kaomi hydraulic (koe ke ʻae ʻia ma ka ʻaelike).
GB8163:
Pono e hoʻokō ʻia ka hoʻāʻo ʻana i ke kaomi hydraulic (a i ʻole ka hoʻāʻo ʻole luku ʻia) e hōʻoia i ka hiki ke hoʻoikaika.
5. Ke kaʻina hana a me ka nānā ʻana
GB8162:
Hiki i ke kaʻina hana (ka ʻōwili wela, ke kaha kiʻi anuanu) ke hoʻokō i nā koi hoʻolālā maʻamau.
He liʻiliʻi nā mea nānā, e like me ka nui, ka maikaʻi o ka ʻili, a me nā waiwai mechanical.
GB8163:
Pono ke kaʻina hana e hōʻoia i ka lōkahi a me ka nui (e like me ka hoʻolei mau ʻana a i ʻole ka hoʻomaʻemaʻe ʻana ma waho o ka umu).
ʻOi aku ka paʻakikī o ka nānā ʻana, me ka hoʻāʻo ʻole luku e like me ka hoʻāʻo ʻana o ka eddy a me ka hoʻāʻo ultrasonic (e pili ana i ke kumu).
6. Ka hōʻailona a me ka hōʻoia
GB8162: Pono e kaha ʻia ka helu maʻamau, mea, kikoʻī, a me nā mea ʻē aʻe, akā ʻaʻohe koi hōʻoia kūikawā.
GB8163: Pono paha ka palapala hōʻoia e pili ana i ka pipeline kaomi hou (e like me ka laikini lako kūikawā).
Nānā:
Hoʻopaʻa loa ʻia ka hui ʻana: Hiki ke hoʻohana ʻia nā paipu kila GB8163 no nā kumu hana (pono e hoʻokō me nā koi GB8162), akā ʻaʻole hiki i nā paipu kila GB8162 ke hoʻololi i ka GB8163 no ka lawe ʻana i ka wai, i ʻole e loaʻa nā pōʻino palekana.
