Nūhou - ʻO ka "poe a pau" i ka pā hao kila

ʻO ka pā kila kalapona kekahi o nā māhele kumu o nā mea kila. Hoʻokumu ʻia ia ma luna o ka hao, me kahi maʻi kalapona ma waena o 0.0218% -2.11% (maʻamau ʻoihana), a ʻaʻohe mea liʻiliʻi o nā mea hoʻohui. Ma muli o ke kalapona, hiki ke hoʻokaʻawale ʻia i:
Haʻahaʻa kalapona kila(C≤0.25%): ʻo ka paʻakikī maikaʻi, maʻalahi e hana, Q235 no kēia ʻano;
kila kalapona waena(0.25%
Ke kila kalapona kiʻekiʻe(C> 0.6%): kiʻekiʻe loa ka paʻakikī a me ka brittleness kiʻekiʻe.

ʻO ke kila kalapona Q235: wehewehe a me nā ʻāpana kumu (GB/T 700-2006 maʻamau)

Huina	C	Si	Mn	P	S

Nā waiwai mīkini:
Ka ikaika hua: ≥235MPa (ka mānoanoa ≤16mm)
Ka ikaika tensile: 375-500MPa
Elongation: ≥26% (mānoanoa ≤16mm)

Mea a me ka hana

Material:Loaʻa nā mea maʻamauGR.B, X42, X46, X52, X56, X60, X65, X70, etc.

Nā ʻano hana
Ikaika Kiekie: Hiki ke pale i ke kaomi kiʻekiʻe i hana ʻia e nā wai e like me ka aila a me ke kinoea maoli i ka wā o ka lawe ʻana.
ʻOoleʻa kiʻekiʻe: ʻAʻole maʻalahi ka haki ʻana i ka hopena o waho a i ʻole nā loli geological, e hōʻoia ana i ka hana palekana o ka pipeline.
Kūleʻa ʻino maikaʻi: E like me nā kaiapuni hoʻohana like ʻole a me ka media, ke koho ʻana i nā mea kūpono a me nā ʻano hana lapaʻau e hiki ke pale pono i ka corrosion a hoʻonui i ke ola lawelawe o ka pipeline.

ʻO ka "koa hexagonal" o Q235

Hana Hana Hana maikaʻi
Weldability: ʻAʻole koi ʻia ka preheating, kūpono no ka hoʻoheheʻe ʻana i ke arc, ka welding gas a me nā kaʻina hana ʻē aʻe (e like me ke kūkulu ʻana i ka hoʻoheheʻe ʻana i ke kila);
Hiki i ke anu: Hiki ke hoʻopiʻi maʻalahi a hoʻopaʻa ʻia (laʻana: ka pahu hoʻolaha, ka pahu hoʻoheheʻe);
Mīkini: Hana kūpaʻa ma lalo o ka ʻoki haʻahaʻa haʻahaʻa (hana ʻāpana mīkini).
Kauna Mechanical Comprehensive

Ka ikaika vs: 235MPa ka ikaika o ka hoʻoulu ʻana e noʻonoʻo i ka lawe ʻana a me ka pale ʻana i ka hopena (hoʻohālikelike ʻia me 195MPa o Q195);
Hiki ke hoʻololi i ka ʻili: He mea maʻalahi ke hoʻoulu a hoʻoulu i ka pena (e like me nā pale pale, nā kiʻi kila māmā).
Kūlana Kūikawā Kūlana
ʻO ke kumukūʻai ma kahi o 15% -20% haʻahaʻa ma mua o ke kila ikaika kiʻekiʻe haʻahaʻa (e like me Q345), kūpono no ka noi nui.
Kiʻekiʻe o ka hoʻohālikelike
ʻO ka mānoanoa maʻamau: 3-50mm (kūʻai lawa, e hōʻemi ana i ka pōʻai maʻamau);
Nā kūlana hoʻokō: GB/T 700 (domestic), ASTM A36 (like international).

Kūʻai a hoʻohana i ka "Avoidance Guide"

ʻIke Kūlana:
Ka nana aku: ʻaʻohe māwae, ʻulaʻula, pelu (GB/T 709 plate shape standard);
Palapala hōʻoia: E nānā i ka haku mele ʻana, nā waiwai mechanical a me ka hōʻike ʻike hala (pono ʻia ka ʻike kīnā UT no nā ʻāpana kūkulu koʻikoʻi).
Hoʻolālā anti-corrosion:
Iloko: pena anti-rust (e like me ka pena kepau ʻulaʻula) + ka lole luna;
Ma waho: hoʻoheheʻe wela (ka uhi ≥85μm) a i ʻole ka hoʻoheheʻe fluorocarbon.
Hoʻomaopopo Welding:
Koho wiliwili: E43 moʻo (e like me J422);
Pāpā lahilahi(≤6mm): ʻaʻole koi ʻia ka hoʻomehana ʻana, ka pā mānoanoa (> 20mm): preheat 100-150 ℃ e pale i nā māwae.

ʻo ka hui kila kila ʻo tianjin i ʻōwili ʻia me ka pā kila

ʻO ka mīkini ʻoki ʻoki CNC, ʻoihana cnc plasma ʻoki ʻia o ka pā metala.

E hahai mai iā mākou e aʻo hou e pili ana i ka ʻike kila.
