S355J2H paipu kila maʻemaʻeEN10210Paipu kila maʻamau maʻamau ʻEulopa.

ʻO S355J2H paipu kila ʻole he ʻano kila i kuhikuhi ʻia maBS EN 10210-1:2006"Non-alloy a me ka maikai-grained structural structural steel hot-formed structural pipes (hollow core material) Part 1: Technical delivery requirements", e pono ai -20 impact energy E hiki aku ana ma mua o 27J, he kila ikaika ikaika ia me maikaʻi ka plasticity a me ka paʻakikī hopena.

S355J2H hoʻohana nui ʻia ka paipu kila ma ka haʻahaʻa haʻahaʻa haʻahaʻa i ka ʻenekinia kila, ke kūkulu hale pāʻani pāʻani nui, a me ka hana ʻana o ka ipu hao. Hiki ke hoʻohana ʻia ka paipu kila S355J2H i ke kūkulu ʻia ʻana o ka paepae aila. S355J2H paipu kila i ka processability maikaʻi a hiki ke hana i haʻahaʻa-mehana mau māhele mechanical.

ʻO ka maʻamau ʻEulopa EN10025-2 ʻōlelo ʻo ka huaʻōlelo e hoʻomaka ana me S he kila structural, a ʻo ka 355 e hahai nei ʻo ia ka liʻiliʻi loa o ka ikaika i ka lumi wela he 355MPa.

ʻO S355J2H kahi kūlana ʻEulopa. He mea wela haʻahaʻa kēia mea. ʻO kona kūlana hoʻokōEN10210, ka mea nui no na paipu kila hili ole a me na paipu huinahalike.

Eia kekahi, hana pū kā mākou hui i nā paipu mechanical a me nā paipu hoʻolālā, e like meASTM A519: ASTM A519-2006Hoʻohana nui ʻia ka maʻamau no nā paipu kila ʻole, nā paipu kila kalapona a me nā paipu mechanical alloy no nā mīkini. ʻO nā paipu mechanical alloy ka mea nui
1018, 1026, 8620, 4130, 4140, etc.

ASTM A53/A53M: ʻO ASTM A53 kahi maʻamau i paʻi ʻia e ka American Society for Testing and Materials (ASTM) e kuhikuhi ana i ka ʻeleʻele a i ʻole galvanized, seamless a welded carbon steel pipe. ʻO ia kekahi o nā kūlana paipu kila i hoʻohana nui ʻia ma ka honua a hoʻohana nui ʻia i ka aila, ke kinoea maoli, kemika, ke kūkulu ʻana a me nā ʻoihana ʻē aʻe.
