ʻO nā Ins a me Outs o nā Seamless Steel Pipes: He Luʻu Hohonu i loko o 20G a me ASTM A106 GRB

I ka wā e pili ana i ke ao o ke kūkulu ʻana a me ka hana ʻana, ʻo nā paipu kila humuhumu nā koa kaulana e hoʻopaʻa ana i nā mea āpau. Ma Jindalai Iron and Steel Group Co., Ltd., haʻaheo mākou i ka hana ʻana i nā paipu humuhumu kiʻekiʻe, me ka paipu kila humuhumu 20G kaulana a me ka paipu kila humuhumu ASTM A106 GRB paʻa. Akā he aha maoli nā paipu kila humuhumu, a no ke aha ʻoe e mālama ai? E hoʻomaka kākou i kahi huakaʻi ma o ka hoʻokaʻawale ʻana, ke kaʻina hana, a me nā waiwai mechanical o kēia mau ʻāpana koʻikoʻi.

ʻO ka mea mua, e hoʻoponopono kākou i ka hoʻokaʻawale ʻana o nā paipu kila humuhumu. Hoʻokaʻawale ʻia nā paipu humuhumu ma muli o kā lākou kaʻina hana, mea hana, a me ka hoʻohana ʻana. ʻO nā ʻano maʻamau ka paipu kila kalapona, nā paipu kila alloy, a me nā paipu kila kila. I loko o kēia mau māhele, e ʻike ʻoe i nā māka kikoʻī e like me ka paipu kila humuhumu 20G, ka mea i makemake nui ʻia no kona ikaika maikaʻi loa a me ke kūpaʻa i nā noi wela kiʻekiʻe. Ma ka ʻaoʻao ʻē aʻe, ua hoʻolālā ʻia ka paipu kila humuhumu ASTM A106 GRB no nā wahi kaomi kiʻekiʻe, e lilo ia i koho no nā ʻoihana aila a me ke kinoea. No laila, inā ʻoe e kūkulu ana i kahi hale kiaʻi kiʻekiʻe a i ʻole e kau ana i nā paipu, aia kahi paipu kila humuhumu i hana ʻia no kāu mau pono.

I kēia manawa, e komo kākou i loko o nā kikoʻī o ke kaʻina hana o nā paipu kila humuhumu ʻole. Hoʻomaka ka huakaʻi me kahi billet kila poepoe paʻa, kahi i hoʻomehana ʻia i kahi mahana kiʻekiʻe a laila hou ʻia e hana i kahi paipu hakahaka. A laila hoʻolōʻihi ʻia kēia paipu a hoʻemi ʻia ke anawaena ma o kekahi mau kaʻina hana, me ka wili ʻana a me ka elongation. ʻO ka hopena? He paipu humuhumu ʻole ʻaʻole wale ka ikaika akā ʻaʻohe ona wili e hiki ai ke hoʻonāwaliwali i nā paipu kuʻuna. Ma Jindalai, hoʻohana mākou i ka ʻenehana kiʻekiʻe loa a me nā ana hoʻomalu maikaʻi koʻikoʻi e hōʻoia i kēlā me kēia paipu kila humuhumu ʻole a mākou e hana ai e kū i nā kūlana kiʻekiʻe loa o ka maikaʻi.

Akā pehea nā ʻano mechanical o kēia mau paipu kila humuhumu? ʻĀ, ʻaʻohe mea pōkole o ka kupaianaha. Hoʻohanohano nā paipu kila humuhumu i ka ikaika tensile kiʻekiʻe, ka ductility maikaʻi loa, a me ke kūpaʻa kupaianaha i ka pala a me nā mahana kiʻekiʻe. No ka laʻana, ua ʻike ʻia ka paipu kila humuhumu 20G no kona hiki ke kū i nā kūlana koʻikoʻi, e kūpono ai no nā mea kanu mana a me nā ʻoihana kemika. I kēia manawa, ua hana ʻia ka paipu kila humuhumu ASTM A106 GRB e lawelawe i nā noi kiʻekiʻe, e hōʻoia ana e hiki iā ia ke kū i nā pilikia o ka lawe ʻana i ka ʻaila a me ke kinoea. I ka pōkole, ua kūkulu ʻia kēia mau paipu e mau, a hana lākou pēlā me ke ʻano.

I ka hopena, he mea nui nā paipu kila humuhumu ʻole i nā ʻoihana like ʻole, a ʻo ka hoʻomaopopo ʻana i kā lākou hoʻokaʻawale ʻana, ke kaʻina hana, a me nā waiwai mechanical he mea nui ia no kekahi mea e pili ana i ke kūkulu ʻana a i ʻole ka hana ʻana. Ma Jindalai Iron and Steel Group Co., Ltd., ua kūpaʻa mākou i ka hāʻawi ʻana i nā paipu kila humuhumu ʻole kiʻekiʻe loa, me nā ʻano 20G a me ASTM A106 GRB, e hoʻokō i nā pono like ʻole o kā mākou mea kūʻai aku. No laila, i ka manawa aʻe e ʻike ai ʻoe i kahi hale kiʻekiʻe a i ʻole kahi paipu ākea, e hoʻomanaʻo i nā paipu kila humuhumu ʻole e hiki ai nā mea āpau. He humuhumu ʻole paha lākou, akā ʻaʻole ʻike ʻia ko lākou hopena!
