Product Overview

A312 TP347H Stainless Hlau Seamless Yeeb Nkabyog niobium-stabilized austenitic stainless hlau yeeb nkab tsim los rau siab - kub thiab corrosive kev pab cuam. Cov khoom raug txheeb xyuas raws li UNS S34709. Nws cov niobium stabilization pab txo rhiab heev thiab intergranular corrosion, thaum qib H- yog npaj rau kev pab cuam qhov twg creep thiab ntxhov siab -rupture zog yog ib qho tseem ceeb.

TP347H yog dav txiav txim siab rau cov nroj tsuag petrochemical, refineries, tsim hluav taws xob, hloov hluav taws xob, cov kav dej, cov khoom siv rau hauv cub tawg thiab lwm yam siab -kub txheej txheem txheej txheem.

ASTM A312 TP347H Stainless Hlau Yeeb Nkab - Daim Ntawv Thov Case

Ib tus neeg siv khoom siv hluav taws xob tau pom tias nws qhov kub siab - cov kav dej kub tau ntsib kev ntxhov siab thermal thiab kev txhawj xeeb corrosion thaum rov ua cua sov thiab cua txias. Peb pom zoo rau ASTM A312 TP347Hstainless steel yeeb nkab, tsom rau nws qhov siab - qhov kub thiab txias thiab haum rau kev nkag siab thiab kev ntxhov siab - kev puas tsuaj.
Tom qab kev kho cua sov kho, kev tshuaj xyuas qhov ntev thiab kev soj ntsuam nruj, cov yeeb nkab tau muab rau qhov kev hloov pauv, muab cov kev daws teeb meem zoo dua rau cov neeg siv khoom siab -kub txheej txheem piping system.

Txhua Yam Koj Yuav Tsum Paub

Puas yog TP347H haum rau siab -kev siv kub?

Yog lawm. ASTM A312 txheeb xyuas TP347H ntawm cov qib npaj rau kev pab cuam qhov twg nkag thiab ntxhov siab- cov khoom tawg yog qhov tseem ceeb.

Qhov txawv ntawm 347 thiab 347H yog dab tsi?

TP347H muaj cov pa roj carbon ntau dua thiab yog tsim los rau kev txhim kho siab -kub creep thiab kev ntxhov siab- kev ua haujlwm tawg.

Dab tsi tus qauv npog TP347H stainless hlau yeeb nkab?

ASTM A312 / ASME SA312 rau stainless hlau yeeb nkab. TP347H kuj tseem tuaj yeem muab tau raws li ASTM A213 / ASME SA213 rau kev siv boiler, superheater thiab cua sov- daim ntawv thov tube pauv.

304 stainless hlau ua tau raws li cov kev cai thoob ntiaj teb ntawm qib zaub mov, 316 stainless hlau tsis yog qib zaub mov lossis qib kho mob nkaus xwb. Txawm li cas los xij, kev siv qib kev kho mob no ua lub khob ntim khoom yuav tsis coj cov txiaj ntsig ntxiv rau txhua tus. Vim li cas thiaj hu 304 lossis 316? Qhov no feem ntau txhais raws li cov khoom muaj pes tsawg leeg . 316 stainless hlau tsis zoo li cov khoom siv ntxhia, tom qab siv tuaj yeem tso qee yam khoom los txhawb tib neeg kev nqus, yuav tsis ua kom huv dej zoo, yog li thaum siv los ua cov khoom siv khob dej, tsis muaj qhov sib txawv. Qhov txawv yog tias tus nqi ntawm cov khoom siv raw yog txawv ntawm qhov loj ntawm lub suab ntawm lub stunt ntev.
