ASTM A312 TP309S Welded Polished yeeb nkab

Raws li tus kws tshaj lij stainless hlau yeeb nkab xa khoom, GNEE muab ntau yam khoom zoo stainless hlau tubular khoom. Yog tias koj tab tom nrhiav kom sov thiab corrosion-resistant ASTM A312 TP309S stainless hlau kav, peb tuaj yeem xa cov kev daws teeb meem rau koj.

Peb muab ASTM A312 TP309S polished kav rau austenitic stainless hlau tubing. Lawv tiv taus cov cua sov rov qab nyob rau hauv 980℃thiab raug tsim los rau siab - kub thiab corrosive kev khiav hauj lwm ib puag ncig. Nrog precision polishing kev kho mob, qhov nto roughness ncav cuag Ra tsawg dua los yog sib npaug rau 0.6 μm, haum kev lag luam nrog nruj huv si yuav tsum muaj xws li cov khoom noj, tshuaj thiab tshuaj engineering.

Peb ASTM A312 TP309S welded stainless hlau kav yog tsim los ntawm TIG / MIG vuam txheej txheem. Lub teeb, ruaj khov welds yog dawb ntawm blowhole tsis xws luag rau installation ntawm complex qauv. Its high chromium content (22–24%) builds a dense chromium oxide barrier to block oxygen penetration and extend service life steadily. Muaj peev xwm ua haujlwm ntev - lub sijhawm ua haujlwm qis dua 980 degree, nws ua tau zoo dua cov qib ib txwm muaj xws li TP304 hauv thermal deformation tsis kam, zoo tagnrho rau cov kav hauv cub hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob thiab cov ntawv siv zoo sib xws.

Vim li cas thiaj xaiv GNEE

GNEE siv lub tshuab nqus tsev smelting tshuab kom ua tiav cov ntsiab lus molybdenum tswj, boosting pitting corrosion kuj ntau dua 20% piv nrog cov pa 316L welded kav.

Nruab nrog tag nrho tsis siv neeg ERW vuam cov cav tov thiab kev sib xyaw hauv online kev kho mob, qhov vuam tsim nyog tus nqi nce siab dua lossis sib npaug rau 99.8%. Peb cov khoom tuav ASME BPVC thiab PED ntawv pov thawj.

Me me -batch customization yog muaj nyob rau hauv qhov tsawg kawg nkaus txiav txim kom muaj nuj nqis ntawm 10 daim, nrog rau qhov ntev raws li qhov ntev thiab customized nto finishing kev pab cuam.

FAQ

1.Dab tsi yog cov khoom ntawm 309S stainless hlau yeeb nkab?

Alloy 309S yog austenitic stainless hlau yeeb nkab uas muaj cov qib siab ntawm chrome thiab npib tsib xee. Qhov sib ntxiv ntawm cov npib tsib xee thiab chrome muab kev txhim kho oxidation nyob rau hauv qhov kub thiab txias mus txog 1830℃F. 309S yog cov pa roj carbon tsawg ntawm 309 thiab paub tias nws yooj yim rau fabricate thiab welding los ntawm cov txheej txheem feem ntau.

2.Dab tsi yog qhov txawv ntawm 316 thiab 309 stainless hlau yeeb nkab?

Lub ntsiab sib txawv ntawm 309 thiab 316 stainless hlau yeeb nkab yog 309 stainless hlau yeeb nkab yog tsim rau kub kub thiab oxidation tsis kam, thaum 316 stainless hlau yeeb nkab yog tsim rau superior corrosion thiab tshuaj tiv thaiv.

3.Dab tsi yog cov khoom ntawm 309S ss raj?

309S ss raj yog ib hom austenitic ss nrog siab chromium thiab npib tsib xee ntsiab lus. Qhov sib ntxiv ntawm nickel thiab chromium txhim kho nws cov oxidation tsis kam ntawm qhov kub txog li 1830℃F (kwv yees li 1000 degree).

4.Dab tsi yog qhov zoo dua, 304 lossis 309s stainless hlau raj?

Lub zog thiab Hardness: 309 stainless hlau nthuav tawm ntau zog thiab hardness piv rau 304 stainless hlau. Cov cwj pwm no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas yuav tsum muaj zog ntxiv, tshwj xeeb tshaj yog nyob rau hauv siab - qhov kub thiab txias.

5.Dab tsi yog qhov txawv ntawm 309 thiab 309S ss raj?

Hom 309 stainless hlau muaj qhov siab tshaj plaws cov ntsiab lus ntawm 0.20% thiab nthuav tawm lub zog siab dua ntawm qhov kub siab heev. Hom 309S yog qhov qis- carbon version, nrog cov ntsiab lus siab tshaj plaws ntawm 0.08%; Cov ntsiab lus qis qis no txo ​​qis carbide nag lossis daus thaum lub sijhawm vuam, yog li txo qhov kev pheej hmoo ntawm intergranular corrosion thiab ua rau nws tsim nyog rau cov ntawv thov uas xav tau vuam.
