SCH 40S A403 WP304/304LSMLS (Tsis muaj)Ncaj Teesyog 300 series austenitic stainless hlau paub txog kev tiv thaiv corrosion zoo heev.SS 304/304 Lmuaj li ntawm 18-20% chromium thiab 8-10.5% npib tsib xee.304L hlauyog ib tug tsawg carbon version ntawm 304 nrog ib tug siab tshaj plaws carbon ntsiab lus ntawm 0.03% thiab yog ntau resistant rau intergranular corrosion. Cov phab ntsa tuab ntawm SCH 40S ua rau nws muaj peev xwm ua haujlwm ntau dua xws li kev ua tshuaj lom neeg, kev kho dej, thiab lwm yam.
ASME B16.9:Tus qauv no tswj hwm qhov loj me, kev kam rau siab, kev ntsuam xyuas, kev sim, thiab cov cim rau lub Hoobkas - ua pob tw - vuam fittings los ntawm NPS 1/2 txog NPS 48. Ib "ncaj tee" qhia tau hais tias cov ceg txoj kab uas hla sib tw khiav txoj kab uas hla raws nraim.
ASTM A403 / ASME SA403 Cov Lus Qhia:Qhov kev qhia tshwj xeeb no suav nrog cov khoom siv rau wrought austenitic stainless hlau piping fittings. CovWPLub npe sawv cev rau "Wrought Pipe," qhia tias qhov haum yog tsim los ntawm seamless lossis welded yeeb nkab blanks.
HT PIPE yog ib tug zoo-paub stockist thiab exporter. Peb yog cov khoom siv alloy 304/304l nrog 15+ kev xa tawm. Peb tsis tsuas yog muab cov kav dej, phaj, puag ncig tuav, tab sis kuj muaj cov yeeb nkab fittings, flanges, thiab lwm yam.Tiv tauj pebyog xav paub ntxiv thiab tus nqi dawb.
Qhov zoo ntawm Dual WP304/304L Certification
Xaiv dual - ntawv pov thawj WP304/304L fittings sib txuas cov txiaj ntsig metallurgical sib txawv ntawm ob qib rau hauv ib qho khoom siv:
WP304 (UNS S30400):Muab qhov zoo tshaj plaws hauv paus txhua yam lub zog, toughness, thiab atmospheric corrosion kuj.
WP304L (UNS S30403):Features txwv qis -carbon profile (0.03% max). Qhov no ua tau zoo tiv thaiv chromium carbide nag lossis daus thaum vuam, khaws cia qhov corrosion kuj ntawm tshav kub- cuam tshuam cheeb tsam (HAZ) yam tsis tas yuav tsum tau ncej-weld annealing.
Ncaj Tee SMLS (Seamless)
- Tee: Ncaj tees muaj peb qhov sib npaug sib npaug thiab siv los faib lossis txuas ob qhov ntws ntawm 90-degree lub kaum sab xis hauv cov kav dej.
- Seamless Construction (SMLS): Seamless fittings tsis muaj welds thiab nyiam dua welded fittings rau qhov chaw siab.
Stainless hlau 304/304L Mechanical Properties
- Tawm Zog: Kwv yees . 205 MPa (30 ksi)
- Tensile zog: kwv yees li . 515 MPa (75 ksi)
- Elongation: 40% (tsawg kawg)
- Hardness: Max . 201 HBW
ASTM A403 WP304 / 304L Thermal Properties
- High Temperature Properties: Haum rau qhov kub thiab txias txog li ntawm . 870℃(1600℃F).
- Low Temperature Properties: 304/304L tuav zoo toughness ntawm qhov kub thiab txias heev.
- Thermal Expansion: 304/304L muaj coefficient siab ntawm thermal expansion piv rau carbon steel.
Weldability
Ob leeg AISI 304 thiab 304L tuaj yeem welded los ntawm cov qauv txheej txheem (TIG, MIG) nrog lossis tsis muaj cov khoom muab tub lim.

Technical FAQ
Q1: Dab tsi yog "Straight Tee" txhais tau tias piv rau "Txo Tee"?
A1: A Ncaj Tee(tseem hu ua Equal Tee) txhais tau hais tias tag nrho peb qhov kev sib txuas xaus -kab kab thiab ob txoj kab tseem ceeb - muaj qhov sib npaug nominal yeeb nkab loj (NPS) thiab phab ntsa tuab. ATxo Teenta ib ceg kab uas me me nyob rau hauv txoj kab uas hla tshaj lub ntsiab khiav kab.
Q2: Vim li cas thiaj hais SCH 40S es tsis yog tus qauv Teem caij 40?
A2:Cov lus "S" qhia txog stainless hlau qhov ntev raws liASME B36.19M. Rau qhov ntau thiab tsawg ntawm 1/2 "thiab 10", SCH 40 thiab SCH 40S qhia cov phab ntsa tuab tib yam. Txawm li cas los xij, rau qhov ntau thiab tsawg 12 "thiab loj dua, tus qauv SCH 40 phab ntsa thickness nce, thaum SCH 40S tseem capped ntawm tus qauv thickness (9.52 hli), txuag cov khoom hnyav qhov siab - carbon steel siab txwv tsis tas yuav tsum tau.
Q3: Cov tees no puas muab cov ntaub ntawv pov thawj?
A3:Yog lawm. Tag nrho ASTM A403 WP304 / 304L fittings muab los ntawm cov chaw tsim khoom lag luam yuav tsum tau nrog rauEN 10204 3.1 Mill Test Certificate (MTC)Kev lees paub tseeb ntawm cov xov tooj cua sov, tshuaj xyuas cov tshuaj muaj pes tsawg leeg, lub zog tensile, lub zog tawm los, elongation, thiab hydrostatic los yog tsis yog - cov txiaj ntsig kev ntsuas kev puas tsuaj.
