Paipu kila humuhumu ʻoleASTM A53, ʻO SCH40, Gr.B kahi paipu kila kiʻekiʻe i hoʻohana nui ʻia ma ka mākeke, me ka hana maikaʻi a me nā ʻano noi like ʻole. Eia ka hoʻolauna i nā pono o kēia paipu kila:

Mea Hana a me ke Kūlana
ASTM A53ʻO ke kūlana maʻamau he kikoʻī paʻa no nā paipu kila humuhumu ʻole ma ka ʻoihana kila US, i hoʻohana nui ʻia no ka ʻaila, ke kinoea kūlohelohe, ka mahu a me nā paipu ʻē aʻe. Hana ʻia kēia paipu kila me ke kila kalapona a i ʻole ke kila alloy haʻahaʻa. Hōʻike ka Papa B (Gr.B) he kiʻekiʻe ka ikaika o ka paipu a me ke kūpaʻa i ke kaomi a kūpono no nā wahi kaomi waena a me ke kiʻekiʻe. Pili ʻo SCH40 i ke kūlana o ka mānoanoa o ka paia paipu, e hōʻoiaʻiʻo ana he lawa ka pale ʻana o ka paipu i ka pala a me ka hiki ke hāpai i ke kaomi.

Kaʻina hana a me ka maikaʻi
Hoʻohana kēia paipu kila i ka ʻenehana hana paipu kila humuhumu holomua e hōʻoia i ka maikaʻi o ka huahana paʻa, ka ʻili paipu laumania, ʻaʻohe hemahema wili, a me ke kūpaʻa maikaʻi loa i ke kaomi a me ke kūpaʻa i ka pala. Ma o ka nānā pono ʻana i ka maikaʻi, hoʻokō ia i nā koi oASTM A53ke kūlana e hōʻoia i ka ikaika, ka paʻakikī, ka ductility a me ke kūpaʻa ʻana i ka pala o kēlā me kēia paipu kila e kū nei i nā kūlana ʻoihana.

Nā kikoʻī a me ka laulā o ka noi
Loaʻa i ka paipu kila humuhumu nā ʻano kikoʻī like ʻole, me nā anawaena waho maʻamau mai 1/8" a 30", a hiki ke hoʻopilikino ʻia ka mānoanoa o ka paia e like me nā pono. Hoʻohana nui ʻia ia ma nā kahua o ka petroleum, kemika, ka mana uila, ke kūkulu moku, nā mīkini, a me nā mea ʻē aʻe, kūpono loa no nā ʻōnaehana pipeline e halihali ana i nā mea wai e like me ka wai, ka ʻaila, a me ke kinoea.

Hoʻohana nui ʻia
ASTM A53Hiki ke hoʻohana ʻia nā paipu kila seamless no nā paipu hoʻoili kiʻekiʻe, nā hale kūkulu, nā paipu paila, nā paipu hoʻoili aila a me ke kinoea kūlohelohe, a pēlā aku, e hoʻololi ana i nā ʻano hana paʻakikī like ʻole, e hāʻawi ana i ka hana halihali hilinaʻi a me nā hōʻoia palekana.
