Paipu humu pololei ʻo Carbon Steel

ʻO ka mea i hoʻohana ʻia no ke kila kalapona ka paipu kila humuhumu pololei, ʻo ia ke kila kalapona, ʻo ia ka mea e pili ana i kahi huila hao-carbon me kahi ʻāpana kalapona oemi iho ma lalo o 2.11%.Loaʻa i ke kila kalapona ka liʻiliʻi o ka silikoni, manganese, sulfur, a me ka phosphorus ma waho o ke kalapona.

ʻO ka mea maʻamau, ʻoi aku ka kiʻekiʻe o ke kalapona i loko o ke kila kalapona, ʻoi aku ka paʻakikī a ʻoi aku ka kiʻekiʻe o ka ikaika, akā ʻoi aku ka haʻahaʻa o ka plasticity.

Hiki ke hoʻokaʻawale ʻia nā paipu kila kila kila kila i nā paipu kila humuhumu kiʻekiʻe a me nā paipu kila humuhumu i loko o ka wai e like me ke kaʻina hana. Hoʻokaʻawale ʻia nā paipu kila i loko o ka UOE, RBE, JCOE, a me nā mea ʻē aʻe e like me kā lākou ʻano hana.

ʻO ke kila carbon steel seam steel pipe kumu hoʻokō maʻamau

GB/T3091-1993 (paipu kila wiliwili ʻia no ka hoʻouna ʻana i ka wai haʻahaʻa haʻahaʻa)

GB/T3092-1993 (paipu kila wiliwili ʻia no ka hoʻouna ʻana i ka wai haʻahaʻa haʻahaʻa)

GB/T14291-1992 (paipu kila welded no ka lawe ʻana o kaʻu wai)

GB/T14980-1994 (Nā paipu kila i hoʻopaʻa ʻia i ka uila no ka lawe ʻana i ka wai haʻahaʻa)

GB/T9711-1997[Petroleum a me ka ʻoihana kinoea hoʻoili i nā paipu kila, me GB/T9771.1 (e hōʻike ana i ke kila A) a me GB/T9711.2 (e hōʻike ana i ke kila B)]

Hoʻohana nui ʻia nā paipu kila kila kila i nā papahana hoʻolako wai, ʻoihana petrochemical, ʻoihana kemika, ʻoihana uila, ʻoihana mahiʻai, a me ke kūkulu kūlanakauhale. Hoʻohana ʻia no ka lawe ʻana i ka wai: lako wai a me ka hoʻokahe. No ka lawe kinoea: kinoea, mahu, liquefied petroleum gas. No nā kumu hana: e like me nā paipu pili, e like me nā alahaka; paipu no na uwapo, alanui, hale, etc.
