S355J2HʻO ka paipu kila maʻemaʻe he kila kiʻekiʻe i hoʻohana nui ʻia i ka hana ʻenekinia a me nā māla ʻoihana. ʻO ka "S355" ma kona inoa e hōʻike ana i kona ikaika hoʻohua, aʻo "J2H" ke hōʻike nei i kona ʻano paʻakikī a me ka hana wili. Ua lanakila kēia paipu kila i ka ʻike ākea ma ka mākeke no kona ikaika kiʻekiʻe, ka plasticity maikaʻi a me ka paʻakikī, a me ka maikaʻi o ka wili a me ka hana ʻana.
I ka wā o ke kaʻina hana,S355J2HPono ka paipu kila maʻemaʻe e hele i nā kaʻina hana he nui, e like me ka hana kila, ka'ōwili, ka perforation, ka mālama wela, a me nā mea'ē aʻe. Eia kekahi, he mea nui ka nānā ʻana i ka maikaʻi a me ka hoʻāʻo ʻana, ʻo ia hoʻi ka nānā piha ʻana i ka nui, ke ʻano, ka hoʻohui ʻana i nā kemika, nā waiwai mechanical a me ka maikaʻi o ka ʻili o ka paipu kila.
S355J2HHe nui ka hoʻohana ʻana o ka paipu kila maʻemaʻe. Hiki ke hoʻohana ʻia e hana i nā ʻāpana mechanical like ʻole, nā ʻāpana hana a me nā ʻōnaehana pipeline. I ka aila, ke kinoea maoli, kemika, ka mana a me nā ʻoihana ʻē aʻe, hoʻohana nui ia e lawe i nā wai a me nā kinoea. I kēia mau noi, ka ikaika kiʻekiʻe a me ka paʻakikī maikaʻi oS355J2Hhiki ke hoʻopaʻa i ka paʻa a me ka palekana o ka ʻōnaehana pipeline.
Kahi mea hou aʻe,S355J2Hpaipu kila seamless no hoi i maikai corrosion kū'ē. ʻO kēia ma muli o kāna hana kemika kūikawā a me ke kaʻina hana wela, e hiki ai i ka paipu kila ke mālama i kāna hana no ka manawa lōʻihi i nā wahi hana paʻakikī. No laila, i loko o nā wahi ʻino loa e like me nā ʻoihana moana a me nā ʻoihana kemika, hiki i ka S355J2H ke hoʻokō i kāna hana maikaʻi loa.
Eia naʻe, e like me nā huahana a pau, S355J2H paipu kila maʻemaʻe ʻole kekahi mau hemahema. No ka laʻana, ma muli o kona ikaika kiʻekiʻe a me ka paʻakikī maikaʻi, pono ka paipu kila i nā koi ʻenehana a me nā mea hana kiʻekiʻe i ka wā o ka hoʻoili ʻana a me ka hoʻonohonoho ʻana. Eia kekahi, ʻoiai ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion o S355J2H seamless steel pipe, hiki i ka ʻino a me ka pōʻino ke hiki i kekahi mau kaiapuni. No laila, i ka wā e hoʻohana ai, pono ka mālama mau a me ka nānā ʻana e hōʻoia i kāna hana paʻa lōʻihi.
Ma keʻano laulā, S355J2H paipu kila maʻemaʻe he kiʻekiʻe, kiʻekiʻe-ikaika kila me ka paʻakikī maikaʻi a me ke kū'ēʻana i ka corrosion. ʻAʻole wale kāna noi ākea ma muli o kāna hana maikaʻi loa, akā hiki ʻole ke hoʻokaʻawale ʻia mai kāna kaʻina hana koʻikoʻi a me ka mana maikaʻi. I ka wā e hiki mai ana, me ka hoʻomau mau ʻana o ka hana ʻenekinia a me nā ʻoihana ʻenehana, e hoʻomau ka S355J2H seamless steel pipe i kāna hana koʻikoʻi a hāʻawi nui i ka hoʻomohala ʻana i nā ʻano āpau o ke ola.
Eia nō naʻe, me ka hoʻomohala ʻana o ka ʻepekema a me ka ʻenehana a me ka hoʻololi mau ʻana i ka makemake o ka mākeke, ke kū nei ka ʻoihana paipu kila seamless i kekahi mau pilikia a me nā manawa hou. Ma kekahiʻaoʻao, ke hoʻomau nei nā kaʻina hana a me nā ʻenehana hou, kahi e hoʻomaikaʻi hou ai i ka hana a me ka maikaʻi o nā paipu kila ʻole. Ma ka ʻaoʻao ʻē aʻe, ʻo ka hoʻololi ʻana o ka noi mākeke ke kau nei i nā koi kiʻekiʻe ma ka hana ʻana i nā paipu kila seamless.
