Khoom Taw qhia

Khoom Taw Qhia

Piv nrog rau cov pa austenitic qib xws li 304 thiab 316, duplex stainless hlau hlab muab kwv yees li ob zaug lub zog tawm los thaum tswj kev ua haujlwm siab corrosion hauv kev tawm tsam hnyav. Qhov kev sib xyaw tshwj xeeb no tso cai rau cov kws tsim qauv tsim cov tshuab nrog txo cov phab ntsa tuab thiab txo qhov hnyav tag nrho yam tsis muaj kev cuam tshuam kev nyab xeeb lossis ua haujlwm ntev.

Ib qho kev nthuav dav ntawm seamless duplex stainless hlau raj yog tsim los ntawm kev siv tshuab ntau lawm thiab kev tswj xyuas zoo kom ua tau raws li cov kev lag luam thoob ntiaj teb nruj.

FAQ

Q: Duplex stainless hlau yog dab tsi thiab vim li cas nws thiaj nyiam tshaj cov qib austenitic?

A: Duplex stainless hlau nta qhov sib npaug microstructural muaj pes tsawg leeg uas muaj qhov sib npaug sib npaug ntawm austenite thiab ferrite. Qhov no dual -theem qauv muab cov neeg kho tshuab muaj zog ntau dua thiab ua haujlwm zoo dua rau qhov chaw corrosion-tshwj xeeb tshaj yog chloride kev nyuaj siab corrosion cracking- ua rau nws zoo tagnrho rau cov chaw lag luam huab cua uas tus qauv 304 lossis 316 qib ua tsis tiav.

Q: Dab tsi thoob ntiaj teb cov qauv tsim ua koj cov raj seamless ua raws li?

Q: Koj puas kam txais customized qhov ntev thiab qhov ntev tshwj xeeb?

A: Yog, kev cai sab nraud diameters, phab ntsa thicknesses, thiab ruaj los yog random lengths haum rau tej engineering project drawings thiab tsim tsis tau haum.

Q: Dab tsi yog qhov tsawg kawg nkaus txiav txim kom muaj nuj nqis rau kev cai ntau lawm?

A: Yam tsawg kawg nkaus txiav txim yog nyob ntawm seb cov khoom siv tshwj xeeb, txoj kab uas hla sab nraud, thiab phab ntsa thickness xav tau. Cov sij hawm tsim khoom yooj yim tau tswj xyuas kom txhawb nqa ob qho kev lag luam loj thiab kev txiav txim me me.

Q: Lub sij hawm xa tuaj rau kev txiav txim yog dab tsi?

A: Cov txheej txheem tsim khoom thiab xa khoom xa tuaj feem ntau yog li ntawm peb mus rau rau lub lis piam, nyob ntawm qhov kev txiav txim ntim, cov khoom muaj, thiab cov kev ntsuas ntsuas.
