Introduction to Russian Standard GOST 19281 09G2S

ʻO ke kūlana Lūkia GOST-33259 09G2S he kila kila haʻahaʻa i hoʻohana mau ʻia no ka hana ʻana i nā ʻāpana like ʻole o ka ʻenekinia a me nā hale kūkulu. Hoʻokō ia i nā koi o ke kūlana aupuni Lūkini GOST 19281-89. 09G2SHe kiʻekiʻe ka ikaika a me ka paʻakikī o ke kila, kūpono no nā noi e hana ana i nā pae wela mai -40 ° C a + 70 ° C.

Material:

Laulā noi:

Hoʻohana pinepine ʻia ke kila Russian maʻamau 09G2S e hana i nā pā kila, nā paipu kila a me nā hale kila, e like me nā hale, nā alahaka, ka ʻaila pipeline, nā pahu, nā moku, a me nā kaʻa. ʻO kona ikaika kiʻekiʻe a me ka weldability maikaʻi e kūpono ia no ka Structural engineering e halihali ana i nā haʻahaʻa static nui, dynamic a me nā haʻalulu.

Pono:

1. ʻO ka ikaika kiʻekiʻe: 09G2S kila ka ikaika tensile maikaʻi a me ka ikaika hua, kūpono no nā hana ʻenekinia me nā koi ikaika o nā mea kiʻekiʻe. 2. Weldability: 09G2S kila i maikai weldability, e maʻalahi no ka welding a me ka pilina hana. 3. ʻO ka plasticity maikaʻi a me ka paʻakikī: He maikaʻi kēia kila a me ka paʻakikī, hiki iā ia ke pale i kekahi mau hopena o waho a me nā deformations. 4. Ke kū'ē kū'ē: Hiki i ka 09G2S ke kila ke hoʻonui i kona kū'ēʻana ma o ka hoʻomaʻamaʻa wela a iʻole ka uhiʻana, e kūpono ana i nā wahi e pono ai ke kū'ēʻana i ka corrosion.

Nā hemahema:

1. Ke kumu kūʻai kiʻekiʻe: Ke hoʻohālikelike ʻia me ke kila haʻahaʻa haʻahaʻa maʻamau, ʻoi aku ka kiʻekiʻe o ke kila 09G2S, hiki ke hoʻonui i nā kumukūʻai hana ma nā noi nui. 2. ʻO ke kila kila kiʻekiʻe: ʻOiai ʻoi aku ka haʻahaʻa o ke kila kila 09G2S, ʻoi aku ka kiʻekiʻe ma mua o ke kila haʻahaʻa haʻahaʻa maʻamau, hiki ke kaupalena i kekahi mau noi kūikawā.

Nā hiʻohiʻona:

1. Ka ikaika kiʻekiʻe: Loaʻa ka ikaika kiʻekiʻe a me ka ikaika tensile, a hiki ke pale i nā ukana nui a me nā pilikia. 2. Paʻa paʻa maikaʻi: loaʻa ka paʻakikī maikaʻi loa a me ka paʻakikī hopena, hiki ke mālama i ka hana paʻa ma lalo o nā haʻalulu a i ʻole nā ​​haʻalulu. 3. ʻO ke kūpaʻa kino maikaʻi: Loaʻa iā ia ke kūpaʻa maikaʻi a hiki ke hoʻohana ʻia i nā wahi humid a corrosive. 4. ʻO ka hana hoʻoponopono maikaʻi: 09G2S kila he mea maʻalahi keʻoki, weld, a me ke anu anuanu, kūpono no nā kaʻina hana likeʻole. Ma keʻano laulā, he ikaika kiʻekiʻe ka ikaika o ka Russian standard 09G2S, weldability maikaʻi a me ka paʻakikī, a he kūpono ia no ka Structural engineering e koi ana i ka ikaika kiʻekiʻe a me ke kū'ēʻana i ka corrosion.

Hoʻohālikelike

Eia kekahi mau kila e like me 09G2S, i like paha me 09G2S i ka hana a me ka hoohana.

Q235B: Q235B mea he kalapona structural kila i ka Chinese standard GB / T 700-2006, he maikai weldability, processability a me ka toughness. Hoʻohana nui ʻia ia i ke kūkulu ʻana, nā alahaka, ka hana ʻana i nā mīkini a me nā māla ʻē aʻe, a loaʻa nā mea like me 09G2S i kekahi mau ʻano o ka hana.

ASTM A36: ʻO ASTM A36 he kila kila kalapona i ka maʻamau ʻAmelika, aia kekahi mau mea like me Q235B i ka hana. Hoʻohana maʻamau ia i ka hana ʻana i nā mea hana i ke kūkulu ʻana, ka hana ʻana a me nā māla ʻē aʻe.

S235JR: S235JR he kalapona kalapona kila ma ka European standard EN 10025-2, e like me Q235B a me ASTM A36 i ka hana. Hoʻohana pinepine ʻia i ke kūkulu ʻana, ka hana ʻana i nā mīkini a me nā māla ʻē aʻe.

A572 Papa 50: He kila haʻahaʻa haʻahaʻa kiʻekiʻe kēia i ka maʻamau ʻAmelika, nona ka weldability maikaʻi a me ke kūpaʻa corrosion. Hoʻohana nui ʻia ia i nā alahaka, ke kūkulu ʻana a me ka hana mīkini kaumaha.

S355JR: ʻO S355JR kahi mea kila haʻahaʻa haʻahaʻa haʻahaʻa ikaika i ka European standard EN 10025-2, kūpono no ke kūkulu ʻana, nā mīkini a me nā pipeline.

E hoʻomanaʻo, ʻoiai ua like kēia mau kila i nā mea like me 09G2S ma ke ʻano o nā waiwai a me nā hoʻohana ʻana, aia paha nā ʻokoʻa i ka haku melemele kikoʻī, nā waiwai mechanical a me nā waiwai hoʻoili. I ke koho ʻana i ke kila kūpono, pono ia e hoʻokumu i kāu koho ma luna o nā koi ʻenehana kikoʻī, nā kikoʻī maʻamau a me nā ʻōlelo a ka mea hana.
