Buttweld Fittings

Duplex hlautaub qab-weld fittingsspecification

ASTM A815 Txuj:Qhov no yog tus qauv specification tsim los ntawm American Society for Testing and Materials (ASTM), uas muab cov lus qhia rau kev tsim thiab siv wrought stainless hlau taub qab vuam fittings.

UNS S31803: UAQhov no yog qib kev xaiv los ntawm Unified Numbering System (UNS) rau stainless hlau. UNS S31803 yog duplex stainless hlau, uas txhais tau hais tias nws muaj ob-theem microstructure uas muaj ob qho tib si austenitic thiab ferritic stainless hlau nplej. Qhov kev sib xyaw ua ke ntawm microstructures imparts cov khoom nrog txhim kho lub zog thiab corrosion kuj piv rau cov qauv austenitic stainless hlau.

Butt-weld Fittings:Cov no yog cov khoom siv los txuas cov kav dej ntawm ntau qhov ntau thiab tsawg thiab cov duab hauv cov kav dej. Butt-weld fittings yog welded rau cov kav dej, tsim kom muaj kev sib koom ua ke kom muaj zog thiab tiv taus. Lawv tuaj nyob rau hauv ntau yam duab xws li luj tshib, tees, reducers, kaus mom, thiab lwm yam.

Duplex Stainless Hlau:Duplex stainless hlau zoo li UNS S31803 muaj qhov sib npaug microstructure ntawm austenite thiab ferrite theem. Qhov no ua rau muaj kev sib xyaw ua ke ntawm lub zog siab thiab zoo heev corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig hnyav xws li cov uas muaj chlorides.

Daim ntawv thov:ASTM A815 UNS S31803 pob tw-weld fittings pom cov ntawv thov hauv kev lag luam uas muaj kev tiv thaiv corrosion, siab zog, thiab zoo weldability yog qhov tseem ceeb. Cov no tuaj yeem suav nrog kev tshawb nrhiav roj thiab roj, kev ua tshuaj lom neeg, cov nroj tsuag petrochemical, thaj chaw marine, thiab lwm yam.
