Yog tias koj muab khoomTP304L stainless hlau yeeb nkab, tej zaum koj yuav hnyav cov kev xaiv ntawm "seamless" thiab "welded," los yog xav tsis meej pem los ntawm ntau tus qauv code. Tsis txhob txhawj xeeb - peb yuav rhuav tshem nws rau koj nrog kev nkag siab ncaj qha los ntawm lub Hoobkas hauv pem teb.
Ua ntej, lub ntsiab lus tseem ceeb: TP304L Stainless Hlau Yeeb Nkab ≠ TP304L Seamless Steel Yeeb Nkab
Cias muab,TP304L stainless hlau yeeb nkabyog ib pawg davuas suav nrog cov khoom los ntawm ob txoj kev tsim khoom loj:
- TP304L Seamless Steel Yeeb Nkab:Ua los ntawm cov txheej txheem xws li tho thiab dov, tsis muaj weld seam thoob plaws nws qhov ntev. Nws nta cov siab sib xws-cov kabmob muaj peev xwm thiab kev ntseeg siab.
- TP304L Welded Steel Yeeb Nkab:Tsim los ntawm dov thiab vuam steel phaj los yog sawb. Nws muaj kev ua haujlwm ntau dua, tus nqi qis dua, thiab qhov tseeb qhov tseeb zoo heev.
Yuav ua li cas xaiv txoj cai TP304L stainless hlau yeeb nkab?
- Nws tag nrho yog nyob ntawm kojdaim ntawv thov:
Cov xwm txheej uas TP304L Seamless Pipe yog nyiam:
1. Siab-siab, siab-kub, lossis ib puag ncig corrosive heev:Piv txwv suav nrog cov txheej txheem piping hauv cov nroj tsuag tshuaj, boiler tshav kub exchanger raj, thiab siab - cov roj thiab cov roj xa hluav taws xob. Cov qauv seamless tshem tawm cov weld seam raws li qhov muaj peev xwm tsis muaj zog.
2. Kev lag luam nrog cov kev cai nruj heev,Xws li aerospace Cheebtsam thiab precision ntsuas tubing.
Yam uas yuav tsum tau khoov los yog flaring:Seamless yeeb nkab muaj ntau homogeneous zog, ua rau nws tsis tshua muaj kev tawg thaum lub sij hawm ua.
- Cov xwm txheej uas TP304L Welded Pipe tuaj yeem txiav txim siab:
Tsawg mus rau nruab nrab -pressure kua hloov:Piv txwv li, cog cov khoom siv dej, dej ntws, qhov cua tshuab, thiab cov khoom noj khoom haus thiab dej haus hloov mus.
Tej yaam num uas yuav tsum tau kho kom zoo nkauj los yog zoo nkauj:Cov kav dej welded feem ntau muaj cov phab ntsa tuab ntau dua thiab ua kom zoo dua, zoo nkauj dua.
Loj - txoj kab uas hla, nyias- phab ntsa kav:Seamless yeeb nkab nyob rau hauv cov specifications yuav nyuaj rau tsim los yog txwv tsis pub kim, ua welded yeeb nkab yog ib qho kev xaiv pheej yig dua.
Tsis txhob cia siab rau "304L" - Kev nkag siab txog cov qauv yog qhov ua rau cov kws tshaj lij sib nrug
Cov khoom siv qib (TP304L) tsuas yog lub hauv paus. Qhov kawg txhais nws qhov kev ua tau zoo yog qhov"cov qauv tsim khoom"nws conforms. Cov qauv sib txawv sib txawv raws li qhov yuav tsum tau ua kom zoo thiab kuaj xyuas qhov pib. Kom meej meej qhia tus qauv code thaum lub sij hawm yuav khoom yog qhov tseem ceeb - nws yog cov lus kev uas koj siv nrog lwm tus neeg thiab koj guarantee ntawm txoj cai.
- General Fluid Transfer:Feem ntau sivASTM A 312 Cov Lus Qhia(suav ob leeg seamless thiab welded). Qhov no yog tus qauv siv dav tshaj plaws.
- Cov cuab yeej siv siab xws li Boilers thiab Heat Exchangers:Yuav tsum sivASME SA213(seamless) los yogSIB 249(welded). Cov no yog cov lej lees paub thoob ntiaj teb rau cov cuab yeej siv siab nrog kev xav tau kev nyab xeeb dua.
- Thaum Duplex Stainless Steel Properties Yuav Tsum Tau:Xa mus rauASTM A790 Cov Lus Qhia Tshwj Xeeb.
- Rau Cov Haujlwm Hauv Tsev (Tuam Tshoj): GB/T 14976feem ntau yog siv.
Cov Lus Qhia Tseem Ceeb Txog TP304L (Cia Cov Ntaub Ntawv Hais Lus)
- Qhov "L" txhais li cas?Nws tus yam ntxwv tseem ceeb yogntxiv - cov ntsiab lus carbon tsawg(C Tsawg dua lossis sib npaug li 0.03%). Qhov no txo qis qhov kev pheej hmoo ntawm "intergranular corrosion" tshwm sim los ntawm carbide nag lossis daus tom qab vuam lossis raug rau qhov kub thiab txias. Yog xav tau vuam, 304L yog qhov kev xaiv zoo dua.
- Nws Muaj Peev Xwm Muaj Peev Xwm:Siv seamless yeeb nkab ua piv txwv, nws muaj cov khoom siv kho tshuab zoo heev ntawm chav tsev kub:Lub zog tensile tuaj yeem ncav cuag Ntau dua lossis sib npaug ntawm 903 MPa, lub zog tawm los Ntau dua lossis sib npaug ntawm 274 MPa, thiab elongation Ntau dua lossis sib npaug li 65%.Qhov no txhais tau tias nws yog ob qho tib si muaj zog thiab tawv, nrog zoo ductility los tiv thaiv deformation.
Lub tswv yim zoo rau cov neeg yuav khoom
1. Qhia txog daim ntawv thov:Qhia meej meej rau koj tus neeg muag khoom qhov twg yuav siv cov yeeb nkab (qhov nruab nrab, qhov kub thiab txias, siab) kom lawv tuaj yeem pom zoo rau hom tsim nyog tshaj plaws (seamless / welded) thiab kev tswj hwm tus qauv.
2. Thov Daim Ntawv Pov Thawj:Nug rauMill Test Certificate (MTC/MTR)ua raws li tus qauv xav tau. Nws yuav tsum suav nrog qhov ntsuas tshuaj muaj pes tsawg leeg thiab cov ntaub ntawv kho tshuab.
3. Nto tiav thiab ua tiav:Ua tib zoo saib xyuas cov yeeb nkab cov tshuaj annealing kev kho mob (tshuaj tiv thaiv corrosion) thiab nto tiav (tshwj xeeb tshaj yog tseem ceeb rau cov khoom noj, tshuaj, thiab kev siv tshuaj ntxuav tes).
4. Tsis txhob muab piv tus nqi:Tus nqi qis qis yuav qhia tau tias muaj kev cuam tshuam hauv cov khoom tuab, txheej txheem tsim khoom, lossis kev tshuaj xyuas. Tus nqi ntawm kev nyab xeeb thiab kev pab cuam lub neej nyob deb tshaj tus nqi pib ntawm cov yeeb nkab.
Peb cia siab tias cov kev paub txog kev lag luam no pab koj kom paub ntau ntxiv thiab muaj kev ruaj ntsegTP304L stainless hlau yeeb nkabkev txiav txim siab. Xaiv cov yeeb nkab zoo tiv thaiv tag nrho cov kab ke.
