Nā nīnau i nīnau pinepine ʻia

1. He aha ka ASTM A312?
ʻO ASTM A312 kahi kikoʻī no ka paipu kila austenitic kila kila kaumaha, i hana anu ʻia, a wili ʻia no ka hoʻohana ʻana i ke ana wela kiʻekiʻe a me nā wahi ʻino.

2. He aha ka paipu kila ʻeleʻele?
He paipu kila ʻeleʻele ka paipu kila ʻaʻole i hoʻoheheʻe ʻia me kahi uhi hao ʻeleʻele. Hoʻonui ka uhi ʻana i ke kūpaʻa i ka pala a hāʻawi i ka paipu i kona ʻano ʻeleʻele maʻamau.

3. He aha nā pono o ka hoʻohana ʻana i nā paipu ʻōwili wela?
Hāʻawi nā paipu ʻōwili wela i kekahi mau pono, me ka hoʻomaikaʻi ʻana i ke ʻano, ka hoʻopau ʻana i ka ʻili kiʻekiʻe, ka pololei o ka dimensional i hoʻomaikaʻi ʻia a me nā waiwai mechanical i hoʻonui ʻia. Hoʻohana pinepine ʻia lākou i nā noi e pono ai nā paipu ikaika, paʻa, a me ka pololei.

4. No ke aha i makemake nui ʻia ai nā paipu kila kalapona ma nā ʻoihana like ʻole?
He mea kaulana nā paipu kila kalapona ma nā ʻoihana like ʻole ma muli o ko lākou ikaika, ke kumukūʻai kūpono, a me ka maʻalahi. Hoʻohana nui ʻia ia i ka ʻimi ʻana i ka ʻaila a me ke kinoea, ka hana kemika, ka hana mana, nā kaʻa, ke kūkulu ʻana a me nā ʻoihana ʻē aʻe he nui.

5. Pehea ka ʻokoʻa o ke kaʻina hana ʻana o ka paipu kila ʻeleʻele mai nā paipu ʻē aʻe?
ʻO ka hana ʻana i nā paipu kila ʻeleʻele e pili ana i nā kaʻina hana hoʻomehana a hoʻoluʻu kūikawā. Hoʻomehana ʻia ke kila i nā mahana kiʻekiʻe, ʻōwili ʻia i loko o nā paipu, a laila hoʻomaʻalili koke ʻia e hana i kahi papa paʻa o ka hao oxide e hāʻawi ana i ka paipu i kona kala ʻeleʻele.

6. He aha nā noi o ka paipu kila ʻeleʻele ASTM A312?
Hoʻohana ʻia ka paipu kila ʻeleʻele ASTM A312 i nā ʻoihana like ʻole, me ka ʻaila a me ke kinoea, nā petrochemicals, ka mālama wai, nā paipu, nā ʻōnaehana HVAC, nā kākoʻo kūkulu, a me ka hana maʻamau. Hoʻohana pinepine ʻia ia no ka lawe ʻana i nā wai a me nā kinoea ma lalo o ke kaomi kiʻekiʻe a me nā kūlana mahana kiʻekiʻe.

7. Hiki ke hoʻohana ʻia nā paipu kila ʻeleʻele ma waho?
ʻAe, loaʻa ka paipu kila ʻeleʻele no nā hana o waho. Hāʻawi ka uhi hao oxide i ka pale maikaʻi loa e kūʻē i ka palaho, e kūpono ai no nā ʻano kūlana kaiapuni like ʻole. Eia nō naʻe, pono paha nā uhi pale hou aʻe i nā wahi palaho loa.

8. He kūpono anei nā ʻōmole ʻōwili wela no nā noi ʻenekinia kikoʻī?
ʻAe, hoʻohana nui ʻia nā paipu ʻōwili wela i nā noi ʻenekinia kikoʻī. ʻO kona pololei o ka dimensional i hoʻomaikaʻi ʻia a me ka hoʻopau ʻana o ka ʻili kiʻekiʻe e kūpono ia no ka hana ʻana i nā ʻāpana kikoʻī kiʻekiʻe, nā mīkini a me nā hale e koi ana i nā hoʻomanawanui paʻa.

9. He aha nā pono o nā paipu kila kalapona i hoʻohālikelike ʻia me nā mea ʻē aʻe?
Hāʻawi nā paipu kila kalapona i kekahi mau pono, me ka ikaika tensile kiʻekiʻe, ke kūpaʻa maikaʻi loa i ka ʻaʻahu ʻana, ka machinability maikaʻi a me ka maʻalahi o ka hoʻopili ʻana. He kūpono hoʻi ke kumukūʻai a loaʻa i nā ʻano nui a me nā kikoʻī like ʻole.

10. He kūpono anei ka paipu kila ʻeleʻele ASTM A312 no nā noi wela kiʻekiʻe?
ʻAe, ua hoʻolālā kūikawā ʻia ka paipu kila ʻeleʻele ASTM A312 no nā noi wela kiʻekiʻe. Loaʻa iā lākou ke kūpaʻa wela maikaʻi loa a kūpono no ka lawe ʻana i ka mahu, ka wai wela a me nā wai wela kiʻekiʻe ʻē aʻe.
