2507 cev

Los tubos super duplex producidos segun la especificacion ASTM A790 se suministran en construccion sin soldadura o soldada. El proceso automatizado para fabricar tubos super duplex no utiliza metales de aporte. Los proveedores de tuberias super duplex recomiendan estas tuberias para aplicaciones propensas a la resistencia general a la corrosion.

La microestructura hibrida de la tuberia Super Duplex 2507 kojora su rendimiento.

Duplex stainless hlau yog cov hlau muaj txiaj ntsig zoo uas tau siv thoob ntiaj teb. Nws tau txais nws lub npe los ntawm qhov tseeb tias nws muaj ob qib sib txawv ntawm cov hlau. Qhov tseem ceeb, Duplex yog Fe-Ni-Cr alloy uas muaj ob-theem ferritic-austenitic stainless-steel microstructure thaum nws nyob hauv chav tsev kub.

Duplex steels yog tus cwj pwm los ntawm high chromium (19¨C28%) thiab molybdenum (txog 5%) thiab qis nickel cov ntsiab lus dua austenitic stainless hlau. Feem ntau siv duplex stainless hlau yog 2205 (22% Chromium, 5% Nickel) thiab 2507 (25% Chromium, 7% Nickel); 2507 yog lub npe hu ua ¡° super duplex¡ ± vim nws qhov siab dua rau corrosion.

Qhov kom zoo dua ntawm kev sib txuas ferritic thiab austenitic qib yog tias cov hlau tshwm sim muaj cov qauv hlau uas muaj ob theem thiab yog li tau txais txiaj ntsig los ntawm cov khoom ntawm ob qho tib si microstructures. Cov khoom no ua rau cov hlau duplex tau nrhiav tom qab hauv kev lag luam hnyav, xws li roj thiab roj nuclear thiab kev ua tshuaj lom neeg.

Lub ferrous hlau yog ib qho uas muaj hlau. Yog li ntawd, stainless hlau yog ferrous hlau raws li lawv cov ntsiab lus tseem ceeb yog hlau, txawm nyob rau hauv cov qib alloyed heev, xws li super duplex stainless hlau, los yog super austenitic stainless hlau.

Seamless Pipes kuj ua rau cov khoom zoo li lub zog siab thiab tiv thaiv corrosion los ntawm cov organic acids. Tsis tas li ntawd, cov kav dej no tuaj yeem tiv taus cov tshuaj inorganic acids thiab chloride ib puag ncig.

Super Duplex Steel Pipes thiab Tubes muaj nyob rau hauv ntau qhov ntev, cov duab zoo li square, duab plaub, thiab lwm yam thiab ntau qhov ntau thiab tsawg. Peb tab tom muab cov qauv zoo ntawm cov khoom ntawm peb cov neeg siv khoom. Peb cov khoom yog muab zoo heev corrosion kuj thiab zoo kawg li dimensional raug.

2507 cov kav dej kuj tseem tuaj yeem ua hluav taws xob fusion welded. Pipes Chaw Tsim Tshuaj los nyob rau hauv tsib chav kawm sib txawv nrog rau txhua chav kawm muaj cov cuab yeej tshwj xeeb teeb tsa. Cov kav hluav taws xob tiv thaiv welded muaj zog dua thiab lawv tuaj yeem siv rau kev vuam dav.

Lub xub ntiag ntawm ferrite nyob rau hauv duplex 2205 welded yeeb nkab yog dab tsi muab rau kev txhim kho kev ua tau zoo ntawm no stainless hlau qib nyob rau hauv caustic media uas muaj ib puag ncig.

Kev tiv thaiv corrosion los ntawm kev sib ntxiv ntawm cov khoom siv alloying, feem ntau cov ntsiab lus chromium. ASTM A790 Pipes yog resistant rau pitting corrosion thiab crevice corrosion. Cov kav dej kuj tuaj yeem yog hluav taws xob fusion welded.

Super Duplex muaj tag nrho cov txiaj ntsig ntawm lwm cov duplex steels, tshwj xeeb tshaj yog cov txiaj ntsig zoo ntawm lawv cov qauv biphasic ntawm cov khoom sib npaug austenitic thiab ferritic stainless hlau. Qhov no microstructure ua rau tag nrho cov duplex steels nyob ib ncig ntawm ob zaug ntau zog raws li ib txwm ib tug qauv ferritic los yog austenitic steels, tab sis Super Duplex muaj ib tug ntau dua chromium thiab molybdenum cov ntsiab lus, muab nws considerably muaj zog tiv thaiv corrosion tshaj nws counterparts.

Qhov kev pabcuam kub ntawm 2205 duplex stainless hlau yuav tsum raug txwv kom qis dua 600ºF. Kev raug kub ntev ntev tuaj yeem ua rau 2205 stainless hlau nkig.
