ʻO ASTM A53 GR.B Paipu kila ʻole
ʻO ka wehewehe pōkole:
ʻO ka ASTM A53 he kila kalapona, hoʻohana ʻia e like me ke kila kila a i ʻole no ka paipu haʻahaʻa haʻahaʻa.
ʻO ASTM A53 Standard ka mea maʻamau maʻamau no nā paipu kila kalapona. ʻO ka paipu kila carbon ka mea nui e pili ana i ka hakina carbon mass ma lalo o 2.11% me ka loaʻa ʻole o nā mea hoʻohui i hoʻohui ʻia o ke kila, me ke kiʻekiʻe o ke kalapona i loko o ke kila kekahi o nā ʻO nā mea koʻikoʻi nui e hoʻololi i kona ikaika o ke kila, piʻi ka paʻakikī, a hoʻemi i ka ductility, ka paʻakikī a me ka hiki ke weld.Ma waho aʻe o ia mea, loaʻa iā ia kahi mea liʻiliʻi o ke silika, manganese, sulfur, phosphorus me ka carbon.Ke hoʻohālikelikeʻia me nāʻano kila'ē aʻe,ʻo ia ka mea mua loa, ka uku haʻahaʻa, ka laulā o ka hana, ka nui loa.He kūpono no ke kaomi inoa PN ≤ 32.0MPa, ka mahana -30-425 ℃ wai, mahu, ea, hydrogen, ammonia, nitrogen a me nā huahana ʻaila, a me nā mea ʻē aʻe.ʻO ka paipu kila kalapona ka mea mua loa e hoʻohana i ka nui loa o nā mea kumu ma ka ʻoihana hou.ʻO nā ʻāina ʻoihana o ka honua, i ka hoʻoikaika ʻana e hoʻonui i ka ikaika kiʻekiʻe haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa a me ka hana ʻana i ke kila kila, ʻo ia hoʻi ka nānā nui ʻana i ka hoʻomaikaʻi ʻana i ka maikaʻi a me ka hoʻonui ʻana i ka laulā o nā ʻano a me ka hoʻohana.ʻO ka ʻāpana o ka hana ʻana i ka huina o ke kila o nā ʻāina, e like me ka mālama ʻia ma kahi o 80%, ʻaʻole ia i hoʻohana nui ʻia i nā hale, nā alahaka, nā alahao, nā kaʻa, nā moku a me nā ʻano ʻoihana hana ʻenehana āpau, akā i ka petrochemical hou. ʻoihana, hoʻomohala kai, ua hoʻohana nui ʻia.
