Puas yog koj tab tom nrhiav rau daim ntawv qhia qhov hnyav rau 304 stainless hlau kav los txhim kho koj qhov kev yuav khoom, kev siv nyiaj txiag engineering, lossis cov txheej txheem luam tawm thoob ntiaj teb?

Nyob rau hauv lub realm ntawm industrial engineering, txawm hais tias koj yuav xam cov qauv loads rau siab - siab tshuab los yog kwv yees thoob ntiaj teb logistics nqi rau loj -scale refinery tej yaam num, peb 304 stainless steel yeeb nkab luj daim ntawv qhia npog tag nrho cov qauv specifications rau seamless thiab welded kav. Cov ntaub ntawv hnyav uas muaj nyob rau hauv tau raug ntsuas raws li ASTM A312 thiab ASME B36.19M tus qauv, xws li Sch 10 txog Sch 160, ua rau koj txiav txim siab qhov hnyav ib ko taw rau ib qho NPS 304 piping koj siv.

 

Qhov hnyav ntawm SS 304 yeeb nkab yog dab tsi?

Qhov hnyav ntawm SS 304 yeeb nkab sib txawv raws li txoj kab uas hla, lub sijhawm (phab ntsa tuab), thiab ntev, xws li kwv yees li 0.245 lbs / ft (0.36 kg / m) rau cov yeeb nkab me me - txoj kab uas hla mus txog 49 lbs / ft (73 kg / m) rau cov kav dej loj. Cov piv txwv muaj xws li 1-nti Sch 40 yeeb nkab ntawm 1.68 lbs / ft.

Yuav ua li cas xam SS 304 yeeb nkab hnyav?

 

Metric (kg/m): W=(OD − WT) × WT × 0.02491
qhov twg OD yog sab nraud (mm) thiab WT yog phab ntsa thickness (mm).

Imperial (lb/ft): W=(OD − WT) × WT × 10.69
qhov twg OD yog sab nraud (inch) thiab WT yog phab ntsa thickness (inch).

 

Distinguishing ntawm 304 Pipe thiab 304 Tube: Feem ntau Pitfalls hauv kev yuav khoom

Hauv kev ua haujlwm ntawm kev yuav khoom, ib qho kev ua yuam kev uas tshwm sim feem ntau yog qhov tsis meej pem cov txheej txheem ntsuas qhov hnyav rau "pipes" piv rau "tubes."
SS 304 Yeeb Nkab: Nws cov specifications feem ntau txhais los ntawm NPS (Nominal Pipe Size) thiab Teem caij (phab ntsa thickness chav kawm, luv luv li Sch). Piv txwv li, 1-nti, Sch 40 yeeb nkab muaj qhov tseeb Outer Diameter (OD) ntawm 33.4 hli.
SS 304 Tube: Nws cov specifications feem ntau txhais los ntawm nws qhov tseeb Outer Diameter (OD) thiab phab ntsa thickness. Piv txwv li, 1-nti raj muaj qhov tseeb Outer Diameter (OD) ntawm 25.4 mm.
Cov Lus Qhia Txog Kev Muag Khoom: Nco ntsoov xyuas seb koj qhov hnyav npaum li cas raws li NPS (rau "cov kav dej") lossis ntawm OD (rau "tubes") kom tsis txhob yuam kev ntawm 20% mus rau 30% hauv koj qhov kev npaj thauj khoom.

 

Lub siab ntsuas ntawm SS 304 SCH 40 yog dab tsi?

Qhov ntsuas siab ntawm Schedule 40 stainless hlau yeeb nkab (SS 304 cov khoom) nws txawv heev nyob ntawm cov yeeb nkab txoj kab uas hla thiab qhov kub thiab txias. Feem ntau hais lus, ntawm qhov kub ntawm 100℃F (kwv yees li 38 degree), qhov ntsuas siab rau me me - txoj kab uas hla piping tuaj yeem tshaj 2,000 psi, qhov 4-inch piping, nws yog kwv yees li 1,000 psi. 2-inch piping muaj qhov ntsuas siab ntawm kwv yees li 1,030 txog 1,250 psi ntawm 100℃F; Txawm li cas los xij, cov txiaj ntsig no txo ​​qis heev thaum qhov kub nce.

ss 304 yeeb nkab hsn code yog dab tsi?

HSN Code dav dav rau SS 304 cov kav dej yog 73044100 (txias- kos / txias- dov seamless raj) los yog 73064000 (welded tubes). Cov kav hlau tsis muaj hlau no feem ntau tau muab cais raws li Tshooj 73 (Cov Cai ntawm Hlau lossis Hlau).

 

ss 304 yeeb nkab nqi ib 'meter'

SS 304 cov yeeb nkab nqi feem ntau yog li ntawm $ 1 txog $ 5+ ib 'meter' rau me me - mus rau - nruab nrab txoj kab uas hla welded kav, tab sis cov nqi hloov pauv raws li phab ntsa thickness (seem), txoj kab uas hla, thiab kev lag luam xav tau. Cov kav dej loj dua lossis hnyav dua -cov kav dej seamless tuaj yeem raug nqi ntau dua, feem ntau muag los ntawm qhov hnyav, nrog ntau lub Hoobkas nqi nyob ib ncig ntawm $ 1,000- $ 2,000 ib tuj.
