304 ss yeeb nkab siab ntsuas

Puas yog koj tab tom nrhiav 304 stainless hlau kav dej tab sis tsis paub meej txog qhov siab tshaj plaws uas lawv tuaj yeem tiv taus zoo? Puas tuaj yeem xaiv qhov kev ntsuas siab tsis raug ua rau muaj kev xau, khoom siv tsis ua haujlwm, lossis txawm tias raug nqi poob qis? Rau cov kws tshaj lij thiab cov thawj tswj kev yuav khoom-tshwj xeeb hauv kev lag luam xws li tshuaj lom neeg, roj thiab roj, thiab kev ua zaub mov, cov no yog qhov tseem ceeb heev.

 

Dab tsi yog Qhov Kev Ntsuas Siab ntawm304 Stainless hlau yeeb nkab?

Lub siab ntsuas ntawm 304 stainless hlau yeeb nkab sib txawv raws li txoj kab uas hla, lub sij hawm (phab ntsa thickness), thiab kub, feem ntau yog li ntawm roughly 900 psi mus rau ntau tshaj 4000 psi rau tus qauv, me me - txoj kab uas hla kav ntawm ambient kub. Feem ntau, cov sijhawm teem sijhawm siab dua (piv txwv li, Teem sijhawm 160) muab kev ntsuas siab dua li qhov qis dua (piv txwv li, Teem sijhawm 10).

Hauv qab no yog cov ntaub ntawv siv rau ASTM A312 TP304 Seamless Yeeb Nkab ntawm ambient kub (72℃F / 22 degree).

Nominal Pipe Loj (NPS)	Sab nraud txoj kab uas hla (OD)	Teem caij (Wall)	Phab ntsa Thickness (mm)	Tso cai ua haujlwm siab (PSI)
1/2"	21.34mm 3	SCH40	2.77mm ib	2,300 PSI
1/2"	21.34mm 3	SCH 80	3.73mm ib	3,500 PSI
1"	33.40mm 3	SCH40	3.38mm ib	2,200 PSI
1"	33.40mm 3	SCH 80	4.55mm 3	3,100 PSI
2"	60.33mm ib	SCH40	3.91mm ib	1,400 PSI
2"	60.33mm ib	SCH 80	5.54mm ib	2,100 PSI

Tswv yim: Cov nqi no yog rau cov kav dej seamless. Rau welded 304 kav dej, koj yuav tsum siv qhov Longitudinal Joint Efficiency Factor (feem ntau yog 0.85), uas zoo txo ​​qhov ntsuas siab los ntawm 15%.

 

304 Stainless Hlau Yeeb Nkab Siab Ntsuas Tshuab xam zauv

Kev ntsuas siab ntawm 304 stainless hlau tubing yog txiav txim siab raws li Barlow's Formula:P=2St/D
Los ntawm kev xav txog qhov tso cai rau kev ntxhov siab (S), phab ntsa thickness (T), thiab sab nraud txoj kab uas hla (D), qhov siab tshaj plaws tso cai tau suav (piv txwv li, 2ST / D).
Rau 304/304L stainless hlau cov ntaub ntawv, qhov raug tso cai kev nyuaj siab ntawm ambient kub li ntawm kwv yees li 16,700 mus rau 20,000 psi (sib npaug rau 115 mus rau 138 MPa); Txawm li cas los xij, qhov kev ntsuas siab tiag tiag nyob ntawm cov yeeb nkab lub Teem caij tus lej (piv txwv li, phab ntsa thickness) nrog rau kev ua haujlwm kub.

FAQ

Q1: Puas tuaj yeem 304 stainless hlau kov 10,000 PSI?
Teb: Feem ntau, tsis yog. Standard NPS qhov ntau thiab tsawg hauv SCH 40/80 tsis tuaj yeem ua haujlwm zoo 10,000 PSI. Koj yuav xav tau "High-Pressure Tubing" nrog cov phab ntsa tuab heev thiab tshwj xeeb sab nraud, lossis txav mus rau qib siab dua - qib alloy xws li 316L lossis Duplex 2205.

 

Q2: Puas yog 304L muaj qhov ntsuas qis dua li 304?
Teb: Yog, me ntsis. Lub "L" sawv cev rau Low Carbon, uas zoo heev rau vuam tab sis ua rau lub zog tensile qis dua piv rau tus qauv 304. Qhov sib txawv no feem ntau yog li 5-10% nyob rau hauv cov txiaj ntsig kev ntxhov siab.

 

Q3: Dab tsi yog qhov kev nyab xeeb rau 304 SS piping?
Teb: Feem ntau cov qauv kev lag luam (ASME) siv qhov kev nyab xeeb ntawm 3-rau-1 lossis 4-rau-1. Yog tias ib lub yeeb nkab muaj qhov tawg siab ntawm 8,000 PSI, lub siab ua haujlwm yuav tsum tau teem rau ntawm 2,000 PSI.
