ASTM A210 tus qauv Seamless Nruab Nrab carbon steel boiler thiab Superheat raj
| Tus Qauv:ASTM SA210 | Cov hlau nplaum los yog tsis yog: Cov hlau carbon |
| Pawg Qib: GrA. GrC | Daim Ntawv Thov: Boiler Yeeb Nkab |
| Thickness: 1 - 100 hli | Kev Kho Mob Nto: Raws li tus neeg yuav tsum tau ua |
| Sab Nraud Txoj Kab uas hla (Puag ncig): 10 - 1000 hli | Txheej Txheem: Kub Dov / Txias Kos |
| Ntev: Ntev ntev lossis ntev random | Kev kho cua sov: Annealing / normalizing |
| Tshooj Puab: Puag ncig | Cov Yeeb Nkab Tshwj Xeeb: Cov Yeeb Nkab Phab Ntsa Tuab |
| Qhov chaw ntawm keeb kwm: Tuam Tshoj | Kev Siv: Boiler thiab Heat Exchanger |
| Daim Ntawv Pov Thawj: ISO9001: 2008 | Kev Ntsuas: ET/UT |
Nws yog feem ntau yog siv los ua cov hlau tsis muaj zog zoo, rau cov kav dej boiler, cov kav dej kub super
rau kev lag luam bolier, cov yeeb nkab hloov pauv cua sov thiab lwm yam. Nrog qhov sib txawv ntawm qhov ntau thiab tsawg thiab tuab
Qib ntawm cov pa roj carbon zoo boiler steel: GrA, GrC
| Khoom | Qib A | Qib C |
| C | ≤0.27 | ≤0.35 |
| Mn | ≤0.93 | 0.29-1.06 |
| P | ≤0.035 | ≤0.035 |
| S | ≤0.035 | ≤0.035 |
| Si | ≥ 0.1 | ≥ 0.1 |
A Rau txhua qhov kev txo qis ntawm 0.01% qis dua qhov siab tshaj plaws ntawm cov pa roj carbon, kev nce ntawm 0.06% manganese saum toj no qhov siab tshaj plaws yuav raug tso cai txog li ntawm 1.35%.
| Qib A | Qib C | |
| Lub zog tensile | ≥ 415 | ≥ 485 |
| Lub Zog Tawm | ≥ 255 | ≥ 275 |
| Tus nqi ntev | ≥ 30 | ≥ 30 |
Kev Ntsuas Hydraustic:
Cov Yeeb Nkab Hlau Yuav Tsum Tau Sim Hydraulically Ib Qho Los Ntawm Ib Qho. Qhov Siab Tshaj Plaws ntawm Kev Ntsuas Yog 20 MPa. Nyob rau hauv Qhov Siab ntawm Kev Ntsuas, Lub Sijhawm Ruaj Khov Yuav Tsum Tsis Tsawg Dua 10 S, Thiab Cov Yeeb Nkab Hlau Yuav Tsum Tsis Txhob Xaus.
Tom qab Tus Neeg Siv Pom Zoo, Kev Ntsuas Hydraulic tuaj yeem hloov los ntawm Eddy Current Testing lossis Magnetic Flux Leakage Testing.
Kev Ntsuas Flattening:
Cov raj uas muaj txoj kab uas hla sab nraud loj dua 22 hli yuav tsum raug kuaj kom tiaj. Yuav tsum tsis txhob muaj qhov tawg, cov pob dawb, lossis cov khoom tsis huv tshwm sim thaum lub sijhawm sim tag nrho.
Kev Ntsuas Kub:
Raws li qhov yuav tsum tau ua ntawm tus neeg yuav khoom thiab tau hais hauv daim ntawv cog lus, cov yeeb nkab hlau nrog sab nraud txoj kab uas hla ≤76mm thiab phab ntsa tuab ≤8mm tuaj yeem ua qhov kev sim flaring. Qhov kev sim tau ua tiav ntawm chav tsev kub nrog lub Taper ntawm 60 °. Tom qab Flaring, qhov nrawm flaring ntawm sab nraud txoj kab uas hla yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm cov lus hauv qab no, thiab cov khoom siv sim yuav tsum tsis txhob pom cov kab nrib pleb lossis cov kab nrib pleb.
Kev Ntsuas Qhov Nyuaj:
Kev ntsuam xyuas Brinell lossis Rockwell hardness yuav tsum ua rau cov qauv los ntawm ob lub raj los ntawm txhua qhov ntau
