Hauv kev tsim khoom lag luam, titanium flange forgings, suav nrog dov forgings, ua haujlwm tseem ceeb hauv kev sib txuas cov khoom tseem ceeb rau kev nyab xeeb thiab ruaj khov ntawm cov khoom siv ua haujlwm. Cov txheej txheem tsim khoom thiab cov kev xav tau ntawm titanium flange forgings yuav tsum tau tswj xyuas kom zoo thiab ua haujlwm zoo.
Titanium flange forgings yog raug rau cov kev cai nruj txog lawv cov kev faib thiab cov khoom specifications.
Ua raws li cov qauv xws li JB4726-4728:
- Carbon steel thiab austenitic stainless hlau forgings nrog nominal siab xws li ntawm {{{0}}.25 MPa txog 1.0 MPa tej zaum yuav raug cais raws li Qib I forgings.
- Rau forgings nrog nominal pressures ntawm 1.6 MPa thiab 6.3 MPa, Qib II los yog siab dua cov qauv yog feem ntau yuav tsum tau, tshwj tsis yog hais tias lwm yam.
- Grade III forgings are mandatory for flange forgings with nominal pressures ≥10.0 MPa, chromium-molybdenum steel forgings with nominal pressures >4.0 MPa, and ferritic steel forgings with nominal pressures >1.6 MPa thiab ua haujlwm kub tsawg dua lossis sib npaug rau -20 degree .
- Kev xaiv cov khoom yog qhov tseem ceeb, yuav tsum tau siv cov khoom zoo titanium alloys ua raws li cov qauv tsim los xyuas kom meej cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab microstructure ua raws li cov qauv tsim.
Kev tsim cov txheej txheem rau flanges, suav nrog caj dab vuam, caj dab taub qab vuam, lub qhov (socket) vuam, thiab cov xov flanges, feem ntau koom nrog cov txheej txheem forging lossis dov.
Cov xwm txheej tshwj xeeb uas xav tau cov phiaj hlau lossis cov ntu yuav tsum ua raws li cov lus qhia nruj:
- Hlau daim hlau yuav tsum tau kuaj xyuas ultrasonic kom tsis muaj qhov tsis xws luag ntawm laminar.
- Cov phaj yuav tsum tau txiav mus rau hauv ib daim hlab raws cov kev taw qhia dov thiab khoov rau hauv cov nplhaib rau caj dab flanges. Lub cylindrical nto ntawm lub nplhaib yuav tsum yog los ntawm cov hlau nto kom tiv thaiv kev ua haujlwm ncaj qha ntawm caj dab flanges los ntawm cov hlau phaj.
- Tag nrho kev nkag mus welds yog qhov tseem ceeb rau kev koom nrog lub nplhaib xaus, ua raws li kev kho cua sov tom qab thiab 100% radiographic lossis ultrasonic kuaj ib JB4730 tus qauv.
- Flange caj dab sab nraud txoj kab nqes rau lub caj dab taub qab vuam, lub qhov (socket) vuam, thiab threaded flanges yuav tsum tsis pub tshaj 7 degree los xyuas kom meej qhov zoo sealing kev ua tau zoo thiab yooj yim ntawm installation.
Cov kev xav tau ntxiv suav nrog qhov zoo ntawm qhov chaw, qhov tseeb qhov tseeb, thiab kev txheeb xyuas thiab ntim cov txheej txheem txhawm rau txhim kho corrosion kuj thiab ua tau raws li cov qauv tsim thiab kev siv tshwj xeeb. Kev ua raws li cov lus qhia nruj no yog qhov tseem ceeb los lav qhov kev ncaj ncees thiab kev ntseeg siab ntawm titanium flange forgings hauv kev lag luam.
