ʻO ASTM A333 Paipu kila haʻahaʻa wela haʻahaʻa

ʻO ka ASTM A333 ka kikoʻī maʻamau i hāʻawi ʻia i nā mea welded a me ke kila ʻole, carbon a me nā paipu alloy i manaʻo ʻia e hoʻohana ʻia ma nā wahi haʻahaʻa haʻahaʻa. Hoʻohana ʻia nā paipu ASTM A333 e like me nā paipu hoʻololi wela a me nā paipu moku.

E like me ka mea i ʻōlelo ʻia ma ka pauku ma luna, hoʻohana ʻia kēia mau paipu ma nā wahi i haʻahaʻa loa ka mahana, hoʻohana ʻia lākou i nā ʻoihana hauʻulu nui, nā ʻoihana kemika a me nā wahi like ʻole. Hoʻohana ʻia lākou e like me nā paipu hoʻokele a hoʻokaʻawale ʻia i nā papa like ʻole. Hana ʻia ka helu ʻana o nā māka o kēia mau paipu ma nā ʻano like ʻole e like me ke kūpaʻa wela, ka ikaika tensile, ka ikaika hāʻawi a me nā haku mele. Hoʻolako ʻia nā paipu ASTM A333 i ʻeiwa mau helu ʻokoʻa i koho ʻia e nā helu aʻe: 1,3,4,6.7,8,9,10, a me 11.

Loaʻa kēia mau paipu i ka NPS 2 "a 36". ʻOiai ʻokoʻa nā papa like ʻole e hoʻāʻo i ka wela awelika e hiki ai i kēia mau paipu ke kū mai-45 degere C, a hiki i-195 degere C. Pono e hana ʻia nā paipu ASTM A333 me ke kaʻina hana ʻole a i ʻole ka hoʻopaʻa ʻana i kahi ʻaʻohe mea hoʻopiha i loko o ka pahu. metala ma ke kaʻina hana kuʻi.


Uhi ka maʻamau ʻo ASTM A333 i ka paia a me ka welded carbon a me ka paipu kila kila i manaʻo ʻia no ka hoʻohana ʻana i nā haʻahaʻa haʻahaʻa. E hana ʻia ka paipu huila ASTM A333 e ka seamless a i ʻole ke kaʻina hana kuʻi me ka hoʻohui ʻole o ka metala hoʻopiha i ka hana wili. E mālama ʻia nā paipu wili ʻole a pau e hoʻomalu i ko lākou microstructure. E hana ʻia nā hoʻāʻo tensile, nā hopena hopena, nā hoʻāʻo hydrostatic, a me nā hoʻāʻo uila nondestructive e like me nā koi i kuhikuhi ʻia. ʻAʻole hiki ke loaʻa kekahi nui o nā huahana ma lalo o kēia kikoʻī no ka mea ʻoi aku ka nui o ka mānoanoa o ka pā i ka hopena maikaʻi ʻole i nā waiwai hopena haʻahaʻa.

ʻO ka hana ʻana o ka paipu kila ASTM A333 me kahi ʻano o nā hemahema ʻike maka e hōʻoiaʻiʻo ai ua hana pono ʻia lākou. E hōʻole ʻia ka paipu kila ASTM A333 inā ʻaʻole i hoʻopuehu ʻia nā hemahema o ka ʻili, akā ʻike ʻia ma luna o kahi ʻāpana nui ma mua o ka mea i manaʻo ʻia he hana hana. Pono pono ka paipu i pau.
