ASTM A376 TP347H kub stainless hlau seamless yeeb
ASTM A376 TP347H kub stainless hlau seamless yeeb
ASTM A376 Tp347H YEEB yog qhov tsis muaj dab tsi, ustenitic stainless hlau raj tsim rau high- kev siv ntsuas kub. Nws tau paub rau nws zoo heev coolin, intergranular corrosion tsis kam, thiab oxidation tsis kam txog 1500℃f (816 degree). Tus "H" hauv 347h qhia tau cov ntsiab lus carbon ntau dua, uas tiv thaiv cov chromium carbide nag lossis txhim kho cov khoom siv ruaj khov tiv thaiv intergranular tom qab vuam. Nws yog dav siv nyob rau hauv lub hwj chim tiam, petrochemical, thiab lwm yam siab- kub, cua sov- tiv taus alloy.
Dab tsi yog qhov tsis zoo ntawm 316 stainless hlau?
Lub ntsiab tseem ceeb ntawm 316 stainless hlau muaj xws li: tus nqi siab dua yog muaj los ntawm Molybdenum thiab npib tsib xee; Qhov nyuaj nyuaj hauv kev machinery thiab txoj kev sib sau rau lwm cov hlau tsis xeb; cov txheej txheem vuam ua ke uas yuav txo nws txoj kev xeb tawm tsam; Thiab ntxim nyiam hnav rau cov ntawv thov swb. Thaum 316 stainless hlau muaj zoo corrosion tsis kam tshaj 304 stainless hlau ua ke dua li 304 stainless hlau, nws tseem tuaj yeem corrode nyob rau hauv qee yam kev mob thiab hnyav dua li qee cov ntaub ntawv.

ASTM A376 TP347H Seamless Stainless Hlau Tube Kev siv
1. Kev lag luam tseem ceeb (cov ntawv thov tseem ceeb)
2. Kev lag luam petrochemical: Ethylene tsoo cov rauv leeg, hydrogen Reformer Tube, thiab lwm cov txheej txheem piping rau high-}}}}} qhov chaw dej khov.
3. Nuclear kev lag luam: qee yam tsis yog - nuclear {{2} ecesar fais fab nroj tsuag uas yuav tsum muaj siab- kev ua tau zoo.
Cov Nta Tseem Ceeb
Siab - kub kev ua tau zoo: kev ua haujlwm tsis tu ncua hauv 800℃F (416 degree), nws muaj oxidation zoo thiab lub zog zoo.
Corrosion Kuj: Qhov sib ntxiv ntawm Niobium ruaj khov rau cov hlau, tiv thaiv carbide nag lossis muab kev tiv thaiv kom zoo rau intergranular corrosion.
Niobium stabilization: Niobium thiab cov pa roj carbon ntau hauv Tp347H yog qhov tseem ceeb rau kev tiv thaiv cov kev xav thiab kev txhim kho corrosion tom qab vuam.
Anustenitic Stainless Hlau: nws cov meustenic microstructure muab kev du loj thiab tawv ntawm ob qho siab thiab kub.
Kev tsim khoom thiab muaj
Cov txheej txheem kev sib tw: tsim cov txheej txheem ua kom txias, ua raws li los ntawm kev kho cua sov, pickling, thiab passivation.
Qhov ntau thiab tsawg: Diam Dej sab nraud (OD) ntau los ntawm 1/2 nti mus rau 30 nti hauv ntau yam txheej txheem txheej txheem tuab (piv txwv li, 40s, nrog rau kev cai muaj. Xaus: Cov yeeb nkab xaus tuaj yeem muab nrog beveled lossis tiaj.
Gnee steel tshwj xeeb hauv kev tsim khoom thiab muag ntau ntawm cov khoom lag luam ntau ntawm stainless hlau, suav nrog 304, 904, 90205 duplex, thiab 316L stainless hlau. Gnee Steel cov khoom tau siv dav hauv chav ua noj, Aerospace, tshuaj lom neeg, hluav taws xob, thiab lub zog nuclear, thiab lub zog nuclear, thiab hluav taws xob tsis zoo ntxiv. Peb kuj tseem muab kev cai siv steel hlau daws teeb meem rau cov neeg siv khoom xav tau. Rau stainless hlau nqe lossis kev cai ua kev daws teeb meem, thov emailru@gneesteelgroup.comRau cov lus hais.
