Dab tsi yog cov khoom ntawm A500 Grb Tube
A500 GR.B yog cov khoom siv American cov txheej txheem rau cov txheej txheem cov hlau txheej txheem / duab plaub nrog cov khoom hauv qab no:
1. Cov Khoom Siv Khoom Siv
Cov qauv kev tswj hwm: Ua raws li qhov yuav tsum tau ua ntawm Astm ATTM A500 tus qauv, uas yog txias tsim Welded / Seamless Cov Qauv Steel Hlau.
Tshuaj lom neeg cov tshuaj: raws li cov pa roj carbon ntau, feem ntau nrog cov pa roj carbon ntau dua lossis sib npaug}. 26%, thiab ntxiv cov kab sib txuas los txhim kho lub zog.
Cov Khoom Siv Neeg Kho Tshuab:
Tensile lub zog ntau dua los yog sib npaug rau 400 MPa, tawm kom muaj zog dua los yog sib npaug rau 290 mpa;
Elongation ntau dua los yog sib npaug rau 18%, nrog kev ua kom zoo thiab cuam tshuam tsis kam.
2. Kev siv cov qauv thiab cov ntawv pov thawj
Cov Qauv Txheej Txheem:
Cov ntau lawm ua raws ATTM A500 tus qauv, thiab qee cov khoom tau dhau mus ua asme lossis Jis ntawv pov thawj kom tau raws li kev xav tau sib txawv. Cov txheej txheem yuav tsum tau ua.
Cov txheej txheem yuav tsum muaj:
Yuav tsim tau raws li seamless lossis ntau zaus welded (ERW) cov leeg, uas txias dov thiab coj ua los yog tempered kom tshem tawm cov kev ntxhov siab.
3. Cov ntawv thov raug thov
Lub Tsev Cov Qauv: Cov Txheej Txheem Kev Ua Siab Loj, Cov Qauv Hlau Txhawb Zog (Cua, Av Qeeg);
Kev tsim tshuab: Engineering Machinery Cev pob txha, tsheb Chassis Cheebtsam;
Marine Engineering: Nkoj Txheej txheem, Offshore Platform Pipes;
Infrastructure: choj trusses, kis cov yees.
4. Kev sib piv nrog lwm cov ntaub ntawv
Kev sib piv nrog A36 Hlau: A500 GR.B muaj lub zog siab dua (A36 tawm los zog tsuas yog 250 MPa) thiab haum rau cov qauv hnyav;
Kev sib piv nrog A513 yog ib lub raj tsav tsheb, tsom mus rau precision machining machising machising machising machising machising machising tshuab, thaum A500 gr. tsom rau lub zog.
5. Kev Ua Lag Luam Cov Lus Qhia thiab Nqi (2025 Siv)
Cov kev qhia tshwj xeeb: Square Ntu Sab ntev 20-500 mm, phab ntsa thickness {mm, ntev {2}} meters;
Qhov nqi ntau: kwv yees li $ 5,330 / tonne (raug rau cov lus qhia tshwj xeeb, txheej txheem thiab thaj av)
