A105 WN RF flanges tiav packing tos tus me nyuam
Nag hmo peb tau ntim tag nrho cov pob ntawm qhov kev txiav txim no, suav nrog flanges, yeeb nkab fittings thiab lwm yam.
A105 yog cov ntaub ntawv code rau carbon steel forgings siv nyob rau hauv pipeline Cheebtsam nyob rau hauv lub American ASTM tus qauv system, sib haum mus rau lub thoob ntiaj teb tus qauv ASTM A105 / A105M thiab Suav standard GB / T12228-2006. Cov khoom no belongs rau cov hlau tsis tshua muaj carbon steel forgings, nrog rau cov tshuaj muaj pes tsawg leeg feem ntau yog carbon (C Tsawg dua los yog sib npaug rau 0.35%) thiab manganese (0.6-1.05%), thiab tswj los ntawm cov kab mob xws li silicon, sulfur, thiab phosphorus. Nws cov khoom siv tshuab yog nyob nruab nrab ntawm 20 # forged steel thiab 16Mn forged steel, nrog lub zog tensile Ntau dua lossis sib npaug rau 485MPa, yield zog Ntau dua lossis sib npaug rau 250MPa, hardness Tsawg dua lossis sib npaug rau HB187, thiab ob qho tib si zoo plasticity thiab txias forging ua cov yam ntxwv.
A105 feem ntau yog siv rau kev tsim cov kabmob siab xws li li qub thiab flanges, thiab siv dav hauv cov teb xws li petrochemicals thiab lub zog. Nws lub zog txhua yam yog siab dua li ntawm No. 20 steel, uas tuaj yeem hloov pauv ib nrab. Txawm li cas los xij, vim nws qhov qis tsis kam rau kev ntxhov siab corrosion tawg thiab qhov sib txawv ntawm lub zog loj, kev hloov pauv rov qab yog txwv. Cov khoom siv no yuav tsum tau forged, thiab cov khoom tiav uas ua tau raws li cov qauv yuav tsum ua kom tau raws li qhov yuav tsum tau muaj ntawm Suav thiab Asmeskas cov kev qhia tshwj xeeb.
Standard lub npe: Carbon steel forgings rau pipeline Cheebtsam. Vim tias tus qauv no tsuas yog qhia txog ib hom carbon steel forging, A105 kuj suav tias yog qib forging carbon steel. A105 kuj yog cov khoom siv code, yog cov hlau tshwj xeeb thiab hom txias forged steel. A105 yog ib qho qis - carbon steel forging zoo ib yam li 20 steel. Muaj ob tus qauv, ib qho yog Asmeskas tus qauv "ASTM A105 / A105M Carbon Steel Forgings rau Pipeline Cheebtsam", thiab lwm yam yog Suav tus qauv "GB / T12228-2006 Cov Txheej Txheem Txheej Txheem rau Carbon Steel Forgings rau General Valves"
