ASTM A106 Seamless Steel Pipes sawv cev rau cov kev daws teeb meem zoo rau siab -kub thiab siab - kev siv siab. Nrog nws cov qib txheem (A, B, C), kev tswj hwm tshuaj lom neeg thiab kev siv tshuab, thiab ntau yam kev tsim khoom, nws tseem yog qhov kev xaiv zoo tshaj plaws rau cov kws tsim khoom thiab cov kws tshaj lij hauv kev lag luam tseem ceeb. Kev xaiv kom raug ntawm qib thiab phab ntsa tuab, nrog rau kev ua raws li cov txheej txheem vuam thiab tuav, ua kom lub sijhawm ntev - kev ntseeg siab thiab kev nyab xeeb hauv kev ua haujlwm.

Lus Cim: Rau txhua qhov kev txo qis ntawm 0.01% qis dua qhov siab tshaj plaws, qhov nce ntawm 0.06% manganese saum toj kawg nkaus tau tso cai, mus txog qhov siab tshaj ntawm 1.35% rau ASME A106.
Mechanical Properties
| Khoom | Qib A | Qib B (Feem ntau) | Qib C |
|---|---|---|---|
| Tensile zog (min) | 48,000 psi (330 MPa) | 60,000 psi (415 MPa) | 70,000 psi (485 MPa) |
| Yield zog (min) | 30,000 psi (205 MPa) | 35,000 psi (240 MPa) | 40,000 psi (275 MPa) |
| Elongation (min%) | 35% | 30% | 30% |
| Daim ntawv thov tseem ceeb | Tsawg-siab chav / dej | General siab -temp/pressure | Ultra{0}}siab siab/temp |
Lus Cim: Qib B yog qib siv dav tshaj plaws, suav nrog ntau dua 90% ntawm qhov siab - kub thiab siab - cov kav xa dej siab xav tau hauv cov chaw tsim khoom thiab cov chaw tsim hluav taws xob.
Kub Rolled manufacturing
ASTM A106 Seamless Steel Yeeb Nkab yog tsim los ntawm kev tsim khoom nruj heev uas ua kom muaj kev ncaj ncees thiab qhov tseeb. Cov txheej txheem feem ntau muaj xws li:
Pipe Blank Kev Npaj: Xaiv cov hlau tua (deoxidized) melted ntawm qhib -hearth, yooj yim oxygen, los yog hluav taws xob rauv txoj kev.
Cua sov & Perforation:Lub billet yog rhuab thiab pierced los ua ib tug hollow plhaub.
Kub Rolling:Lub plhaub yog dov kom ua tiav qhov xav tau sab nraud thiab phab ntsa thickness.
Loj & Txo:Qhov kawg qhov ntev yog ua tiav los ntawm sizing mills.
Kev kho cua sov: Thaum kub - cov kav dej tiav tsis tas yuav tsum tau kho cua sov, lawv yuav muaj kev ntxhov siab -relieved ntawm qhov kub siab tshaj los yog sib npaug rau 650℃yog tias tau teev tseg. Txias- cov kav dej yuav tsum tau kho cua sov tom qab qhov kawg kos dhau.
Qhov zoo ntawm Seamless Pipes
Siab zog: Haum rau siab -siab thiab siab - qhov kub thiab txias.
Tsis muaj Weld Seam:Tshem tawm txoj kev pheej hmoo ntawm kev sib tsoo tsis ua haujlwm, ua kom muaj kev sib haum xeeb hauv lub zog nyob ib puag ncig.
Formability:Muaj peev xwm ua tau khoov, coiled, flanged, thiab welded yam tsis muaj cracking, muab cov txheej txheem tsim nyog tau ua raws
Daim ntawv thov
ASTM A106 seamless kav yog feem ntau siv nyob rau hauv kev lag luam uas yuav tsum tau txhim khu kev qha thauj cov kua thiab gases nyob rau hauv cov mob hnyav:
Fais fab nroj tsuag:Boiler tubes, superheaters, thiab chav kab.
Petrochemical Kev Lag Luam:Refinery piping, cracking units, thiab txheej txheem kab.
Roj thiab Roj: siab - cov kab sib kis thiab cov chaw tawm ntug dej hiav txwv.
Shipbuilding:High -kub kua system.
Muaj boilers:Cov phab ntsa dej, cov khoom siv nyiaj txiag, thiab cov khoom siv rov ua dua tshiab
