P235GH steel yog ib qho uas tsis yog - alloy siab - kub siab lub nkoj steel phaj teej tug mus rau European txheem system. Nws cov yam ntxwv tseem ceeb yog nws lub peev xwm los tswj cov khoom siv kho tshuab ruaj khov nyob rau hauv siab - qhov kub thiab txias. Feem ntau, cov hlau no tuaj yeem ua haujlwm tsis tu ncua nyob rau hauv qhov kub ntawm -10 degrees Celsius txog 450 degrees Celsius, thiab txawm mus txog 500 degrees Celsius rau lub sijhawm luv. Qhov kev kub siab tiv thaiv no ua rau nws yog cov khoom siv zoo tshaj plaws rau kev tsim khoom xws li boilers, kub exchangers, thiab reactors.
P235GH yeeb nkab qhov ntev daim ntawv qhia
p235GH cev hnyav
Cov qauv kev suav yog: Nyhav ib ' meter ' (kg / m)=0.02466 × phab ntsa thickness (mm) × (sab nraud txoj kab uas hla (mm) - phab ntsa thickness (mm))
Piv txwv li, sab nraud txoj kab uas hla ntawm P235GH seamless yeeb nkab yog 108 hli, thiab phab ntsa thickness yog 8 hli. Hloov cov nqi no rau hauv cov qauv, peb tau txais: Qhov hnyav ib meter=0.02466 × 8 × (108 - 8).
Ua ntej, xam tus nqi hauv kab lus: 108 - 8=100.
Tom qab ntawd, ua qhov sib npaug: 0.02466 × 8=0.19728, thiab 0.19728 × 100=19.728 kg / m.

P235GH Yeeb Nkab Ntau Lawm Txheej Txheem
Round billet cua sov: Tsis tu ncua cam khwb cia puag ncig billets yog rhuab mus rau kwv yees li 1200℃los xyuas kom meej cov yas deformability.
Piercing thiab sib sau: Cov khoom siv hluav taws xob tau hloov mus rau hauv lub plhaub hollow siv tus ntoo khaub lig- dov piercing zeb, nrog kev tswj nruj ntawm phab ntsa thickness uniformity.
Cov yeeb nkab dov thiab elongation: Ntau qhov dov hla yog ua los ntawm kev siv lub tshuab mandrel los yog lub rooj zaum thawb kom kho cov qauv nplej.
Sizing thiab straightening: Txias- dov lossis txias- cov txheej txheem kos duab meej tswj cov kab nruab nrab sab nraud (feem ntau ± 1%).
Kev kho cua sov: Normalizing kev kho mob (900℃± 20 degree) yog siv los txo cov kev ntxhov siab sab hauv thiab txhim kho cov khoom siv kho tshuab.
Tsis yog -kev kuaj kev puas tsuaj: 100% ultrasonic kuaj (UT) thiab eddy tam sim no kuaj (ET) yog ua los xyuas kom meej qhov tsis muaj cov kab nrib pleb, inclusions, thiab lwm yam tsis xws luag.
GNEE Group cov yeeb nkab steel ntau lawm tau ua tiav cov kab tsim khoom, nrog rau cov khoom kam rau siab txog ± 0.5% thiab nto roughness Ra tsawg dua lossis sib npaug li 12.5 μm.
