ASTM A106 Scope
Hom yeeb nkab: seamless steel yeeb nkab.
Nominal Yeeb Nkab Loj: Npog seamless steel yeeb nkab los ntawm DN6-DN1200 (NPS1/8-NWS 48).
Phab ntsa Thickness: Phab ntsa thickness yuav tsum tau ua raws li cov kev cai tshwj xeeb ntawm Table 1 ntawmASME B36.10M.
ASTM A106 Qib
ASTM A106 muaj peb qib ntawm cov yeeb nkab steel: Qib A,Qib B, thiab Qib C.
Qhov sib txawv tseem ceeb ntawm peb qib yog cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab.
ASTM A106 Raw Khoom
Cov hlau yuav raug tua hlau.
Cov hlau yog tsim los siv cov txheej txheem melting thawj, uas tuaj yeem yog qhov qhib-hearth, yooj yim-oxygen, lossis hluav taws xob-qhov cub, tejzaum nws ua ke nrog cais degassing lossis refining.
ASTM A106 Seamless Steel Pipe Generation Method
Seamless steel yeeb nkabyog tsim nyob rau hauv ob txoj kev: txias-draw thiab kub-tiav.
DN ≤ 40mm seamless steel yeeb nkab tuaj yeem ua kom txias lossis kub tiav.
DN ≥ 50mm seamless steel yeeb nkab yog kub tiav.
Kev kho kub
Kub-tiav ASTM A106 seamless steel yeeb nkab tsis xav tau kev kho cua sov.
Cold-drawn ASTM A106 seamless steel raj yuav tsum tau kho cua sov ntawm qhov kub thiab txias ≥ 650 ° C.
Tshuaj muaj pes tsawg leeg
ASTM A106 Qib A, Qib B, thiab Qib C hauv cov tshuaj muaj pes tsawg leeg ntawm qhov sib txawv loj tshaj plaws yog qhov sib txawv ntawm cov ntsiab lus ntawm C thiab Mn, cov ntsiab lus ntawm lwm cov ntsiab lus hauv ntau qib yuav muaj qhov sib txawv me ntsis, tab sis feem ntau yuav tswj tau ib qho. kuj tsawg.
Mechanical Properties
Qhov tsawg kawg nkaus elongation nyob rau hauv 2 in. (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 hauv 2 hauv. (50 mm), %, sib npaug rau qhov ze tshaj 0.5%
A: cross-sectional cheeb tsam ntawm lub nro test specimen, in2(mm2) raws li tau teev tseg sab nraud txoj kab uas hla lossis nominal qauv dav thiab cov phab ntsa thickness,rounded rau qhov ze tshaj 0.01 in2(1 hli2).
Yog hais tias thaj tsam li xam yog sib npaug los yog ntau tshaj 0.75 in2(500 hli2), ces tus nqi 0.75 in2(500 hli2) yuav tsum tau siv.

Kev Xeem
ASTM A106 muaj cov ncauj lus kom ntxaws ntxaws rau cov tshuaj muaj pes tsawg leeg, kev ntsuas thermal, cov khoom siv cuab yeej cuab tam, kev xav tau dabtsi yog khoov, ntsuas kev sib tw, kev sim hydrostatic, thiab kev kuaj hluav taws xob tsis zoo.
Chemical Composition / Heat Analysis
Kev Ntsuas Kub Kub yog txheej txheem siv los txiav txim siab cov ntsiab lus ntawm cov khoom siv tshuaj lom neeg hauv cov hlau los xyuas kom meej tias cov tshuaj muaj pes tsawg leeg ntawm txhua yam khoom ua tau raws li qhov xav tau ntawm ASTM A106.
Kev txiav txim siab ntawm cov tshuaj muaj pes tsawg leeg yog ua raws li kev ntsuas thermal.Lub hom phiaj tseem ceeb yog nyob rau hauv cov ntsiab lus ntawm cov ntsiab lus carbon, manganese, phosphorus, sulfur, thiab silicon, cov proportions uas muaj kev cuam tshuam ncaj qha rau cov khoom ntawm cov yeeb nkab.
Tensile Requirements
Tubes yuav tsum ua tau raws li qhov tshwj xeeb tensile lub zog, tawm los lub zog, thiab elongation yuav tsum tau.Qhov no ua kom lub zog thiab toughness ntawm lub raj ntawm qhov kub thiab txias.
Khoov yuav tsum tau
Kev ntsuam xyuas kev khoov yog siv los ntsuas qhov toughness thiab yas deformation ntawm cov raj thaum raug khoov kev ntxhov siab txhawm rau txhawm rau ua kom ntseeg tau ntawm cov raj thaum lub sijhawm teeb tsa thiab siv.
Flattening Tests
Flattening Tests yog siv los soj ntsuam cov ductility thiab tsis kam mus tawg ntawm steel hlab.Qhov kev sim no xav kom cov yeeb nkab yuav tsum flattened mus rau ib qho degree tsis muaj cracking los ua pov thawj qhov zoo ntawm cov khoom thiab cov kev tsim nyog ntawm kev ua technology.
Hydrostatic Test
Kev ntsuam xyuas hydrostatic yog ib kauj ruam tseem ceeb hauv kev kuaj xyuas lub peev xwm ntawm cov yeeb nkab steel los ntawm kev siv lub siab siab dua li qhov yuav tsum tau ua los ntawm tus qauv los xyuas kom meej nws cov qauv kev ncaj ncees thiab tsis muaj cov dej xau.
Nondestructive Electric Test
Nondestructive Electric Test (xws li kuaj ultrasonic lossis electromagnetic test) yog siv los txheeb xyuas qhov tsis xws luag sab hauv thiab saum npoo xws li cov kab nrib pleb, suav nrog, lossis qhov hauv cov raj steel kom paub meej cov khoom zoo.
Dimensional Tolerances
Pawg
Qhov loj ntawm cov yeeb nkab yuav tsum nyob rau hauv qhov ntau ntawm97.5% - 110%ntawm qhov teev loj.

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].
Kev kho qhov tsis xws luag
Kev txiav txim siab ntawm qhov tsis xws luag
Thaum muaj qhov tsis xws luag nyob rau hauv cov hlab ntau tshaj 12.5% ntawm nominal phab ntsa thickness los yog tshaj qhov tsawg kawg nkaus phab ntsa thickness, qhov tsis xws luag yuav tsum tau muab tshem tawm los ntawm kev sib tsoo raws li ntev raws li cov seem phab ntsa thickness yog 87.5% los yog ntau tshaj ntawm cov thickness uas teev.
Cov tsis raug mob
Txhawm rau ua kom lub ntsej muag kho raws li cov txheej txheem yuav tsum tau ua, cov hauv qab no tsis raug mob yuav tsum tau muab tshem tawm los ntawm kev sib tsoo:
1. Mechanical marks and abrasions - xws li cable marks, dents, guide marks, rolling marks, ball scratches, indentations and pwm marks, and pits, not any of which will be over 1/16 in (1.6mm) in depth.
2. Kev pom qhov tsis zoo, feem ntau yog cov crusts, seams, laps, kua muag, los yog cov hlais tob tshaj li 5 feem pua ntawm cov phab ntsa nominal thickness.
Kho qhov tsis xws luag
Thaum blemishes los yog tsis xws luag raug tshem tawm los ntawm kev sib tsoo, ib tug du nkhaus nto yuav tsum tau khaws cia thiab cov yeeb nkab phab ntsa thickness yuav tsum tsis txhob yuav tsawg tshaj li 87.5% ntawm cov thickness.
Kho welds yog ua raws li ASTM A530 / A530M.
Tube Marking
Txhua ASTM A106 steel yeeb nkab yuav tsum raug cim nrog cov chaw tsim khoom cov cim qhia, qib tshwj xeeb, qhov ntev, thiab Teem caij cov ntaub ntawv rau kev txheeb xyuas tau yooj yim thiab taug qab.
Rau kev ntsuas hluav taws xob hydrostatic lossis tsis muaj kev puas tsuaj rau cov cim hauv qab no yuav tsum ua raws li:
| Hydro | NDE | Kos npe |
| Yog lawm | No | Kuaj Siab |
| No | Yog lawm | NDE |
| No | No | NH |
