Tolerance rau Seamless Tubing
Raws liASTM A519 Cov Lus Qhia Tshwj XeebthiabAPI 7-1Cov qauv, cov kev zam rau AISI 4145H seamless raj yog:
Sab nraud txoj kab uas hla (OD):
OD Tsawg dua lossis sib npaug 2.5 ": ± 0.015" (0.38mm)
OD 2.5" - 6": ± 0.030" (0.76mm)
OD> 6": ± 0.05% rau ± 1% ntawm nominal OD
Phab ntsa Thickness:
Feem ntau±10%ntawm nominal thickness los yog+12.5% / -10%.
Kev ncaj:
Rau cov dab tshos thiab cov yeeb nkab yuav tsum nruj nruj, feem ntau tsis tshaj1.6mm rau 1000mm(0.019 hli / ft).
Kev sib piv nrog cov ntaub ntawv zoo sib xws
| Qib | Qhov txawv tseem ceeb | Pros / Cons |
| TIAB SA 4140 | Cov pa roj carbon qis (0.38-0.43%) | Tsawg hardenability; tsis zoo rau cov cuab yeej siv txoj kab uas hla loj heev (tshaj 5 "). |
| AISI 4145H | Cov pa roj carbon ntau dua / tswj tau (0.43-0.48%) | Tsim tshwj xeeb rau kev sib sib zog nqus- qhov drilling; muab cov khoom sib xws hardness hauv cov ntu loj. |
| TIAB SA 4130 | Cov pa roj carbon tsawg (0.30%) | Tsawg zog; feem ntau yog siv rau cov cuab yeej siv lub taub hau zoo dua li kev sib hloov cov hlua tho. |
| TIAB SA 4340 | Muaj 1.65-2.00% Nickel (Ni) | Zoo toughness tab sis ho kim dua; tsuas yog siv rau ultra- lub luag haujlwm hnyav lossis siab - thauj khoom hauv qab hiav txwv. |
Daim ntawv thov: SMLS PIPE AISI 4145H
Vim nws lub zog siab thiab kev qaug zog zoo dua, cov khoom siv no feem ntau yog siv rau:
Drill Collars:Muab qhov hnyav - ntawm - ntsis (WOB) thiab tswj cov kev taw qhia ntawm lub laum ntsis.
Heavy Weight Drill Pipe (HWDP):Ua haujlwm raws li kev hloov pauv ntawm nyias- cov yeeb nkab laum phab ntsa thiab cov hlua hnyav hnyav.
Tool Joints:Cov threaded kawg ntawm cov yeeb nkab laum uas yuav tsum tau siab siab - zaus ua - thiab - tawg cycles.
Stabilizers thiab Reamers:Downhole cov cuab yeej siv los txhim kho txoj hlua laum thiab tuav txoj kab uas hla zoo.
Cov cuab yeej nuv ntses:Siab -cov cuab yeej rov qab muaj zog siv los khaws cov khoom ploj ntawm lub qhov dej.

FAQ
Aisi 4145H sib npaug li cas?
AISI 4145H tsis muaj "zoo meej" 1: 1 kev sib tw hauv txhua lub tshuab thoob ntiaj teb vim nws cov pa roj carbon tshwj xeeb (0.43-0.48%), tab sis cov hauv qab no yog qhov sib npaug zoo tshaj plaws:
European Standard (EN / DIN): 42CrMo4(Cov Khoom No:1.7225) - Nco tseg: Qhov no yog qhov sib npaug ntawm kev lag luam tshaj plaws.
Suav Standard (GB): 42CrMolos yog45CrMo.
Japanese Standard (JIS): SCM445(los yogSCM445 H).
British Standard (BS): 708M40(zoo li qubEN19).
Dab tsi yog qhov txawv ntawm AISI 4145 thiab 4145H?
Qhov sib txawv tseem ceeb yog qhov"H", uas stands rauHardenability.
TSI 4145:Tsuas yog qhia covtshuaj muaj pes tsawg leeg(cov khoom xyaw). Tsis muaj kev lav phib xaub ntawm qhov tob npaum li cas cov hlau yuav tawv thaum kho cua sov.
AISI 4145H:Qhia meej txog cov tshuaj muaj pes tsawg leeg thiabguaranteed hardenability. Nws yuav tsum dhau aJominy kawg -quench testlos ua pov thawj tias nws yuav ncav cuag ib qho hardness ntawm ib qho tob.
Puas yog AISI 4145H Steel Corrosion Resistant?
Tsis muaj.AISI 4145H yog aqis- hlau alloy, tsis yog corrosion-resistant (stainless) steel.
Rusts yooj yim:Nws yuav xeb thiab corrode thaum raug ya raws, oxygen, lossis dej ntsev.
Tsawg Chromium:Nws tsuas muaj txog1% Chromium, qhov tseeb "corrosion-resistant" stainless hlau xav tau yam tsawg kawg nkaus10.5% Chromium.
Kev tiv thaiv xav tau:Hauv kev siv roj av, nws yuav tsum tau tiv thaiv los ntawm cov txheej txheem tshwj xeeb, cov tshuaj tiv thaiv corrosion, lossis kev kho cua sov tshwj xeeb (rau "Sour Service") kom muaj sia nyob hauv qhov chaw hnyav.
