HT PIPE yog ib tug thawj coj stockist thiab thoob ntiaj teb exporter nrog ntau tshaj 15 xyoo ntawm kev txawj ntse nyob rau hauv thoob ntiaj teb kev lag luam. Peb muab cov kav dej, daim hlau, cov kab tuav, thiab ntau yam ntawm cov yeeb nkab fittings, flanges, thiab li qub. Tiv tauj peb tam sim no rau cov lus qhia pub dawb thiab cov ntaub ntawv khoom ntiag tug.
Cov yam ntxwv tseem ceeb
Temperature resistance range:Lub sij hawm ntev siv kub -196℃~ 650 degree, luv luv tuaj yeem tiv taus kub ntawm 800 degree.
Corrosion kuj:Nws muaj kev tiv thaiv corrosion zoo dua li 304 stainless hlau hauv nruab nrab thiab tsis muaj zog acidic media (xws li dej tshiab, chav dej, thiab cov kua tshuaj me me), tshwj xeeb tshaj yog nyob rau hauv kub oxidation thiab intergranular corrosion kuj.
Mechanical zog:Tensile zog Ntau dua los yog sib npaug rau 515MPa, yield zog Ntau tshaj los yog sib npaug rau 205MPa, elongation Ntau tshaj los yog sib npaug rau 40%, nrog zoo dabtsi yog khoov formability thiab weldability.

Material Stabilization: UNS S32100 vs WP321H
Rau qhov kub thiab txias, xaiv qhov raug sub-qib yog qhov tseem ceeb rau kev ua neej nyob. Thaum tus qauv ASTM A403 WP321 yog qhov zoo tshaj plaws rau kev siv dav dav dav - kub txog li 800 degree, peb kuj tsimWP321H (siab carbon ntsiab lus 0.04% - 0.10%)cev khoov. Qhov siab dua carbon chemistry ntawm qib "H" muab ntau dua creep zog thiab rupture lub zog ntawm kev khiav hauj lwm kub siab tshaj 500℃(932℃F), ua rau nws nyiam qib rau superheater raj thiab petrochemical catalyst kav.
s321 yeeb nkab khoov Common specification parameters
- Tube diam:DN15 (1/2 nti) ~ DN2000 (80 nti), npog cov kav dej seamless, welded kav, thiab cov kav dej sib txuas. cov
- Khoov vojvoog:txheem 1.5D, 3D, 5D (D yog cov yeeb nkab txoj kab uas hla), customizable tsis yog - tus qauv vojvoog (xws li 0.5D, 10D). cov
- Khoov kaum sab xis:90 degree, 45 degree, 180℃(U-khoov), txhawb customized cov ces kaum tshwj xeeb xws li 30 degree, 60 degree, thiab lwm yam.
- Phab ntsa thickness qib:SCH10, SCH20, SCH40, SCH80, SCH160, ua raws li ASTM A403 thiab ASME B16.9 tus qauv. cov

Rigorous Quality Control and Compliance Testing
Txhua lub raj xa dej tawm hauv peb lub Hoobkas tau dhau qhov kev sim ua ntu zus los xyuas qhov tseeb qhov tseeb thiab cov khoom siv hlau:
Kev daws Annealing:Tag nrho cov kub-tsim stainless hlau 321 khoov yog cov kev daws teeb meem-annealed ntawm 1040℃mus rau 1150℃tom qab los ntawm cov dej ceev ceev kom rov qab siab tshaj corrosion thiab tshem tawm cov kev ntxhov siab sab hauv.
Tsis yog -Kev Ntsuas Kev Puas Tsuaj (NDT):Peb ua 100% Radiographic Testing (RT) ntawm welded seams, Liquid Penetrant Testing (LPT) ntawm lub vojvoog khoov kom pom qhov chaw micro-fissures, thiab Ultrasonic Thickness (UT) gauging kom paub meej qhov ntev ntawm phab ntsa.
Dimensional soj ntsuam:Kev txheeb xyuas ntawm lub kaum sab xis, qhov nruab nrab- mus rau- qhov kawg qhov ntev, thiab bevel profileing raws li ASME B16.25 tus qauv.
ASME B16.9 Stainless Hlau 321 Yeeb Nkab Khoov FAQ
Q: Vim li cas thiaj siv SS 321 yeeb nkab khoov siv SS 304 lossis 316 hauv siab -kub tshuab?
A: SS 321 yog titanium-stabilized, uas tiv thaiv chromium carbide nag lossis daus thiab intergranular corrosion nyob rau hauv 425℃mus rau 900℃(800℃F txog 1650℃F) ntau qhov twg 304 thiab 316 tsis ua haujlwm.
Q: Koj yuav ua li cas tiv thaiv cov phab ntsa ntau dhau ntawm qhov nkhaus ntawm qhov khoov?
A: Peb xaiv cov kav dej pib nrog lub npe nominal phab ntsa tuab thiab siv cov txheej txheem kub induction bending tswj kom ntseeg tau tias qhov kawg extrados ua tau raws li ASME B16.9 yam tsawg kawg nkaus phab ntsa.
Q: Dab tsi yog qhov ua haujlwm sib txawv ntawm WP321 thiab WP321H cov yeeb nkab khoov?
A: WP321H muaj cov ntsiab lus carbon ntau dua (0.04% mus rau 0.10%), uas muab ntau dua creep thiab tawg lub zog ntawm qhov kub thiab txias ua haujlwm siab tshaj 500 degree.
