Lwm cov duab
xws li streamlined, hexagonal, octagonal, puag ncig hauv thiab hexagonal lossis octagonal sab nraud, ribbed sab hauv lossis tawm, daim duab peb sab, puag ncig thiab D duab.
Cov khoom siv raw
Cov hlau tuaj yeem ua los ntawm txhua qhov txheej txheem.
Thawj melting yuav suav nrog cais degassing los yog refining thiab tej zaum yuav ua raws li theem nrab melting, xws li electro slag los yog nqus-arc remelting.
Cov hlau yuav raug cam khwb cia rau hauv ingots los yog strand cast.
ASTM A513 Cov txheej txheem tsim khoom
Tubes yuav tsum tau ua los ntawm covHluav taws xob tsis kam-welded (ERW)txheej txheem thiab yuav tsum tau ua los ntawm kub dov los yog txias dov hlau raws li tau teev tseg.
ERW yeeb nkab yog txheej txheem ntawm kev tsim cov vuam los ntawm coiling cov khoom siv hlau rau hauv lub tog raj kheej thiab siv cov kev tiv thaiv thiab siab raws nws qhov ntev.
Kub Rolled Steel: Nyob rau hauv cov txheej txheem ntau lawm, kub-dov hlau yog thawj rhuab nyob rau hauv high kub, cia cov hlau yuav dov nyob rau hauv ib tug yas lub xeev, uas ua rau nws yooj yim los hloov cov duab thiab loj ntawm cov hlau.Thaum kawg ntawm cov txheej txheem kub dov, cov khoom feem ntau yog scaled thiab deformed.
Cold-Rolled Steel: Cold-dov hlau yog dov ntxiv tom qab cov khoom tau txias kom ua tiav qhov xav tau loj thiab cov duab.Cov txheej txheem no feem ntau yog ua nyob rau hauv chav tsev kub thiab ua rau cov hlau nrog zoo nto zoo thiab ntau qhov ntev.
Kev kho kub
Thaum lub thermal mob tsis tau teev tseg, lub raj yuav muab tau rau hauv NA mob.
Thaum qhov kev kho cua sov kawg tau teev tseg, qhov nruj oxide yog qhov qub.
Thaum qhov chaw tsis muaj oxide tau teev tseg, lub raj yuav ci ntsa iab los yog pickled ntawm qhov chaw tsim khoom xaiv.
Vuam Seam Handling
Sab nraud welds yuav tsum tau ntxuav
Internal welds yuav muaj qhov siab sib txawv nyob ntawm seb hom.
Cov kev cai tshwj xeeb tuaj yeem pom hauv ASTM A513, ntu 12.3.
Tshuaj muaj pes tsawg leeg ntawm ASTM A513
Cov hlau yuav tsum ua raws li cov txheej txheem tshuaj lom neeg uas tau teev tseg hauv Table 1 lossis Table 2.
Thaum cov qib carbon steel raug txiav txim los ntawm tus qauv, nws tsis tso cai los muab cov qib alloy uas tshwj xeeb hu rau qhov sib ntxiv ntawm cov khoom uas tsis yog cov teev hauv Tables I thiab 2.
Yog tias tsis muaj qib qhia, qib MT 1010 txog MT 1020 muaj.
Mechanical Properties ntawm ASTM A513
Kev ntsuas tensile yuav tsum tau ua ib zaug ib zaug.
Thaum "Yuav tsum tau Tensile Properties" tau teev nyob rau hauv Daim Ntawv Txiav Txim Siab, cov tubing puag ncig yuav tsum ua raws li qhov yuav tsum tau muaj tensile thiab tsis tas yuav tsum tau ua rau cov kev txwv hardness qhia hauv Table 5.
Hardness Test
1% ntawm tag nrho cov raj hauv txhua qhov ntau thiab tsis pub tsawg dua 5 lub raj.
Flattening Test
Cov hlab ntsha thiab cov hlab ntsha uas tsim lwm cov duab thaum lawv puag ncig yog siv tau.
Tsis muaj qhov qhib hauv qhov vuam yuav tsum tau ua kom txog thaum qhov kev ncua deb ntawm cov phiaj yog tsawg dua li ob feem peb ntawm qhov qub sab nraud ntawm lub raj.
Tsis muaj cov kab nrib pleb lossis tawg hauv lub hauv paus hlau yuav tsum tshwm sim kom txog thaum qhov kev ncua deb ntawm daim hlau yog tsawg tshaj li ib feem peb ntawm cov thawj sab nraud txoj kab uas hla ntawm cov tubing tab sis nyob rau hauv tsis muaj tsawg tshaj li tsib lub sij hawm lub thickness ntawm lub tubing phab ntsa.
Cov ntaub ntawv pov thawj ntawm cov lamination lossis cov khoom siv hluav taws kub yuav tsum tsis txhob tsim thaum lub sij hawm flattening txheej txheem, thiab lub vuam yuav tsum tsis txhob pom qhov raug mob.
Nco tseg: Thaum qhov qis D-rau-t piv tubing raug kuaj, vim tias qhov kev cuam tshuam vim yog geometry yog qhov tsis tsim nyog siab ntawm qhov chaw sab hauv ntawm qhov chaw rau rau thiab kaum ob teev, cov kab nrib pleb ntawm cov chaw no yuav tsis ua rau kev tsis lees paub yog tias cov D-rau-t piv yog tsawg dua 10.
Flaring Test
Cov hlab ntsha thiab cov hlab ntsha uas tsim lwm cov duab thaum lawv puag ncig yog siv tau.
Ib ntu ntawm lub raj kwv yees li 4 hauv [100 mm] ntev yuav tsum sawv ntsug flared nrog lub cuab yeej muaj 60 ° nrog lub kaum sab xis kom txog rau thaum lub raj ntawm lub qhov ncauj ntawm qhov flare tau nthuav dav 15% ntawm txoj kab uas hla sab hauv, tsis muaj qhov tawg lossis nthuav tawm. qhov tsis haum.
Hydrostatic Test Round Tubing
Tag nrho cov tubing yuav tau txais kev kuaj hydrostatic.
Khaws qhov tsawg kawg nkaus ntsuas ntsuas dej tsis pub tsawg tshaj 5s.
Lub siab yog xam raws li:
P = 2st/D
P= yam tsawg kawg nkaus hydrostatic xeem siab, psi lossis MPa,
S= tso cai fiber ntau kev nyuaj siab ntawm 14,000 psi los yog 96.5 MPa,
t= teev phab ntsa thickness, in. or mm,
D= teev sab nraud txoj kab uas hla, in. los yog mm.
Nondestructive Electric Test
Nws yog lub hom phiaj ntawm qhov kev sim no kom tsis lees txais cov hlab ntsha uas muaj kev raug mob.
Txhua lub raj yuav tsum raug kuaj nrog qhov ntsuas hluav taws xob tsis zoo raws li Kev Xyaum E213, Xyaum E273, Xyaum E309, lossis Xyaum E570.
