ASTM A106 1steel yeeb nkab yog seamlesscarbon steel yeeb nkabhaum rau siv nyob rau hauv qhov kub thiab txias ib puag ncig.Nws yog dav siv nyob rau hauv ntau lub teb xws li roj thiab roj kev lag luam, fais fab nroj tsuag thiab tshuaj nroj tsuag.
Tshwj xeeb,ASTM A106 Qib Btubing yog tshwj xeeb tshaj yog nrov rau ntau daim ntawv thov vim nws muaj peev xwm ua tau raws li cov neeg kho tshuab kev xav tau ntawm feem ntau siv machinery thiab nws cov nqi pheej yig.
ASME SA106 = ASTM A106.
ASME SA106 thiab ASTM A106 yog qhov sib npaug ntawm cov khoom siv thiab cov khoom, thiab muaj cov txheej txheem zoo ib yam, tab sis koom nrog cov koom haum tshaj tawm cov qauv sib txawv thiab siv los ua kom tau raws li cov txheej txheem ntawv pov thawj sib txawv.
Nominal Dia: DN 6 - DN 1200 [NPS 1/8 - NPS 48];
Sab nraud: 10.3 - 1219 mm [0.405 - 48 nyob rau hauv.];
Phab ntsa thicknessesmuaj raws li qhia hauvASME B 36.10.
Common phab ntsa thickness chav kawm yogTeem caij 40thiabTeem caij 80.
Cov yeeb nkab loj dua li cov qauv siv tau, yog tias nws ua tau raws li tag nrho lwm cov cai ntawm cov cai no.
CovASTM A106 1tus qauv muaj peb qib sib txawv,Qib A, Qib B, thiab Qib C.
Lub zog tawm los thiab lub zog tensile nce nrog qib, uas yog siv los tiv thaiv kev sib txawv ntawm kev siv ib puag ncig.
Cov hlau yuav raug tua hlau.
ASTM A106 steel yeeb nkab yuav tsum tau tsim los siv aseamless ntau lawm txheej txheem.
Nyob ntawm qhov loj ntawm cov yeeb nkab thiab cov ntawv thov tshwj xeeb, lawv tuaj yeem raug cais ntxiv rau hauvkub tiavthiabtxias txiashom.
DN ≤ 40 [NPS ≤ 1 1/2], tuaj yeem ua kom kub tiav lossis txias kos, feem ntau yog kos txias.
DN ≥ 50 [NPS ≥ 2] yuav tsum kub tiav.Cold-drawn seamless steel tubes kuj muaj raws li qhov kev thov.
Hauv qab no yog ib daim duab schematic ntawm cov txheej txheem ntau lawm ntawm kub-tiav seamless steel yeeb nkab.
Cold-drawn production flow chart schematics tuaj yeem pom los ntawm txhaj rauASTM A556 Cold Drawn Seamless Carbon Steel Tubes.
Kub-tiav thiab txias-drawn seamless steel raj muaj cov khoom siv kho tshuab, qhov zoo ntawm qhov chaw, thiab qhov tseeb qhov tseeb ntxiv rau qhov sib txawv ntawm qhov sib txawv.
Cov raj kub ua tiav yog tsim los ntawm qhov kub thiab txias thiab muaj zog zoo dua tab sis rougher nto thiab qis qhov tseeb;whereas txias-draw hlab yog tsim los ntawm yas deformation nyob rau hauv chav tsev kub thiab muaj zog dua, smoother nto, thiab ntau precision dimension tswj, ua rau lawv haum rau daim ntaub ntawv uas yuav tsum tau ntau dua precision thiab kev ua tau zoo.
Txias-txiastubing yuav tsum tau kho cua sov ntawm1200 ° F [650 ° C]lossis siab dua tom qab kos duab txias kawg.
Kub-tiavsteel hlab feem ntau tsis tas yuav tsum tau kho cua sov ntxiv.
Yog tias qhov kev kho cua sov yuav tsum tau ua rau kub tiav steel yeeb nkab, qhov kev kho cua sov yuav tsum yog saum toj no1500 ° F [650 ° C].
Kev kho cua sov txhim kho lub microstructure ntawm lub raj, txhim kho cov khoom siv kho tshuab, txhim khu kev tiv thaiv corrosion, txhim kho kev ua haujlwm, ua kom muaj kev ruaj ntseg, thiab ua tau raws li cov kev cai ntawm cov qauv tshwj xeeb, yog li ua kom muaj txiaj ntsig zoo thiab tsim nyog ntawm lub raj.
a Rau txhua qhov kev txo qis ntawm 0.01% qis dua cov pa roj carbon siab tshaj plaws, qhov nce ntawm 0.06% manganese saum toj no qhov siab tshaj plaws yuav raug tso cai mus txog qhov siab tshaj ntawm 1.35%.
b Tshwj tsis yog tias tau teev tseg los ntawm tus neeg yuav khoom, rau txhua qhov txo qis ntawm 0.01% qis dua cov pa roj carbon siab tshaj plaws, qhov nce ntawm 0.06% manganese saum toj kawg nkaus yuav raug tso cai mus txog qhov siab tshaj ntawm 1.65%.
cCr, Cu, Mo, Ni, thiab V yuav tsum tsis pub tshaj 1% ntawm tag nrho cov ntsiab lus ntawm tsib lub ntsiab lus.
Qib A, B thiab Ctxawv nyob rau hauv lawv cov tshuaj muaj pes tsawg leeg, feem ntau nyob rau hauv cov nqe lus ntawm carbon thiab manganese cov ntsiab lus.
Cov kev sib txawv no cuam tshuam rau cov khoom siv kho tshuab thiab daim ntawv thov scenarios ntawm cov hlab.Qhov siab dua cov ntsiab lus carbon, cov yeeb nkab yuav muaj zog dua, tab sis lub toughness yuav raug txo.Kev nce hauv cov ntsiab lus ntawm manganese pab txhawb lub zog thiab hardness ntawm cov hlau.
Tensile Khoom
A: Qhov tsawg kawg nkaus elongation nyob rau hauv 2 nyob rau hauv. [50 mm] yuav tsum tau txiav txim los ntawm cov nram qab no kab zauv:
inch-phaus units:e = 625,000 A0.2/UO.9
Sl units:e = 1940 A0.2/U0.9
e: yam tsawg kawg nkaus elongation nyob rau hauv 2 hauv. [50 mm], %, sib npaug rau qhov ze tshaj 0.5%,
A: cross-sectional cheeb tsam ntawm lub nro test specimen, in.2[mm2], raws li tau teev tseg sab nraud txoj kab uas hla los yog nominal specimen dav thiab teev phab ntsa thickness, sib npaug rau qhov ze tshaj 0.01 hauv2[1 hli2].
(Yog hais tias thaj tsam li xam yog sib npaug los yog ntau dua 0.75 in2[500 hli2], ces tus nqi 0.75 in2[500 hli2] yuav tsum tau siv.),
U: teev tensile zog, psi [MPa].
Bending Test
Rau cov kav dej DN 50 [NPS 2] thiab me dua, yuav tsum muaj qhov ntev txaus ntawm cov yeeb nkab kom cia txias khoov ntawm cov yeeb nkab mus txog 90 ° yam tsis muaj qhov tawg ntawm ib lub cylindrical mandrel nrog txoj kab uas hla 12 npaug ntawm txoj kab uas hla sab nraud ntawm cov yeeb nkab.
Rau OD> 25in.[635mm], yog OD / T ≤ 7, yuav tsum tau khoov 180 ° tsis tawg ntawm chav tsev kub.Sab hauv txoj kab uas hla ntawm qhov khoov yog 1in.
Flattening Test
ASTM A106 seamless steel yeeb nkab tsis tas yuav tsum tau flattened xeem, tab sis kev ua tau zoo ntawm cov yeeb nkab yuav tsum ua tau raws li qhov yuav tsum tau ua.
Tshwj tsis yog tias yuav tsum tau ua tshwj xeeb, txhua cov yeeb nkab yuav tsum tau sim hydro los yog tsis muaj kev puas tsuaj hluav taws xob, thiab qee zaum ob qho tib si.
Yog tias tsis muaj kev sim hydrostatic lossis tsis muaj kev puas tsuaj, cov yeeb nkab yuav tsum raug cim nrog "NH”.
Hydrostatic Test
Tus nqi ntawm cov dej siab yuav tsum tsis pub tsawg tshaj 60% ntawm qhov tsawg kawg nkaus yield zog.
Nws tuaj yeem xam los ntawm cov qauv hauv qab no:
P = 2st/D
P = hydrostatic test siab hauv psi lossis MPa,
S = yeeb nkab phab ntsa kev nyuaj siab hauv psi lossis MPa,
t = teev nominal phab ntsa thickness, nominal phab ntsa thickness sib haum mus rau teev ANSI lub sij hawm tus naj npawb, los yog 1.143 lub sij hawm qhov tsawg kawg nkaus phab ntsa thickness, nyob rau hauv. [mm],
D = teev sab nraud txoj kab uas hla, sab nraud txoj kab uas hla raws li teev ANSI yeeb nkab loj, los yog sab nraud txoj kab uas hla xam los ntawm kev ntxiv 2t (raws li tau hais los saum toj no) rau cov teev hauv txoj kab uas hla, in. [mm].
Yog tias qhov ntsuas dej siab tau ua tiav, cov yeeb nkab steel yuav tsum tau cim nrog lubxeem siab.
Nondestructive Electric Test
Nws tuaj yeem siv los ua lwm txoj hauv kev kuaj hydrostatic.
Tag nrho lub cev ntawm txhua cov yeeb nkab yuav tsum raug kuaj xyuas hluav taws xob tsis muaj kev puas tsuaj raws liE213, E309, los yogE570specifications.
Yog tias qhov kev sim tsis muaj kev puas tsuaj tau ua tiav, "NDE” yuav tsum tau qhia nyob rau saum npoo ntawm cov yeeb nkab.
Pawg
Qhov loj ntawm cov yeeb nkab yuav tsum nyob rau hauv qhov ntau ntawm97.5% - 110%ntawm qhov teev loj.
Sab nraud
Thickness
Qhov tsawg kawg nkaus phab ntsa thickness = 87.5% ntawm cov phab ntsa thickness.
Ntev
Nws tuaj yeem categorized rau hauvqhia ntev, ib leeg random ntev, thiabob chav random ntev.
Qhia ntev: raws li xav tau los ntawm kev txiav txim.
Ib leeg random ntev: 4.8-6.7 m [16-22ft].
5% ntawm qhov ntev tau tso cai tsawg dua 4.8 m [16 ft], tab sis tsis luv dua 3.7 m [12 ft].
Muab ob npaug rau random lengths: Qhov nruab nrab qhov ntev tsawg kawg nkaus yog 10.7 m [35 ft] thiab qhov ntev tsawg kawg yog 6.7 m [22 ft].
Tsib feem pua ntawm qhov ntev tau tso cai tsawg dua 6.7 m [22 ft], tab sis tsis luv dua 4.8 m [16 ft].
