ASTM SA210 GrAhe kila kalapona haʻahaʻa (C≤0.27%), nona nā mea e like me ka manganese (Mn 0.93% max) a me ka silicon (Si 0.10-0.20%) e hōʻoia i nā waiwai mechanical maikaʻi a me ka hiki ke hana.

Hoʻomaikaʻi ka haʻahaʻa o ka sulfur a me ka phosphorus (P≤0.035%, S≤0.035%) i ke kūpaʻa ʻana i ka oxidation wela kiʻekiʻe.

Hana maikaʻi loa

Ke kūpaʻa wela kiʻekiʻe: ka mahana hana lōʻihi ≤450 ℃, pōkole a hiki i 480 ℃.

Ke kūʻai ʻana i ke kaomi kiʻekiʻe: kūpono no nā paipu paila haʻahaʻa a me ke kaomi haʻahaʻa ≤5.88MPa.

Hoʻohālikelike kaʻina hana: maʻalahi ke hoʻoheheʻe, kūlou a me ke kaʻina hana anu, kūpono no nā pepa paipu paila, nā poʻomanaʻo a me nā ʻāpana ʻē aʻe.

Nā kūlana koʻikoʻi

E hoʻokō meASTM SA210 GrAnā kūlana, a halaGB/T 3087, ASME a me nā palapala hōʻoia ʻē aʻe e hōʻoia i ka palekana a me ka hilinaʻi.

ʻO ka paipu kila ASTM SA210 GrA seamless he koho kūpono no nā kahua aʻe:

ʻOihana paila: paia wai paila, superheater, economizer a me nā mea nui ʻē aʻe.

Mea hoʻololi wela: nā paipu condenser a me nā evaporator i ka ʻoihana petrochemical.

Ikehu mana: nā paipu hoʻoili mahu a me nā ʻōnaehana kōkua o nā mea kanu mana wela.

Ka pono o ke kumukūʻai: Ke hoʻohālikelike ʻia me nā paipu kila me ka huila, hōʻemi nui nā paipu kila kalapona ASTM SA210 GrA i nā kumukūʻai kūʻai me ka hoʻokō ʻana i nā koi hana.

Lako paʻa: Ma ke ʻano he mea paipu paila maʻamau, ua lawa ka waihona mākeke a ua pōkole ke kaʻina hana hoʻouna.

Hāʻawi mākou i ka ʻoki maʻamau, ka hoʻāʻo ʻana ʻaʻole luku (UT/RT), ka hōʻike mea a me nā lawelawe ʻē aʻe no nā paipu kila seamless ASTM SA210 GrA, a kākoʻo i ka hoʻolaha logistics honua.

ASTM SA210 GrAUa lilo ka paipu kila kalapona i huahana hoʻohālikelike ma ke kahua o nā paila a me nā mea hoʻololi wela ma muli o kāna hana paʻa a me ka hoʻokele waiwai. Inā makemake ʻoe i nā ʻōkuhi loea a i ʻole kahi ʻōlelo kūʻai, e ʻoluʻolu e kelepona i kā mākou hui loea!
