Dab tsi yog lub ntsiab lus ntawm astm 312 seamless yeeb nkab?
Tso lus
ASTM A312 TPP04Puas yog ib qho ntawm feem ntau dav siv cov kev siv stainless hlau tsis muaj kev pab, tshuaj lom neeg, lossis kev xaiv cov khoom zoo, lossis cov khoom lag luam yog tias yuav ua tau zoo {}}
Dab tsi yog lub ntsiab lus ntawm astm 312 seamless yeeb nkab?
| Lub caij | Lub ntsiab |
|---|---|
| ASTM | American Society rau kev sim thiab cov ntaub ntawv - lub koom haum uas tau teeb tsa tus qauv thoob ntiaj teb |
| A312 | Qhov tshwj xeeb ASTM qauv rau seamless, welded, thiab hnyav txias-ua haujlwm nquag ua haujlwm autenitic hlau kav |
| Tus ntsias | RAJ / StrABER Qib (siv los xaiv cov yeeb nkab steel hlau) |
| 304 | Stainless Hlau Qib 304 - Tus Hlau Austenitic nrog cov khoom siv corrosion zoo heev thiab zoo weldability |
Yog li,ASTM A312 TPP04hais txog welded los yog seamless austenitic stainless hlau yeeb nkab ua los ntawm hom 304 stainless hlau thiab dav corrosion service.
304 Stainless Hlau Yeeb Nkab Cov Tshuaj Muaj pes tsawg leeg
| Lub ntsiab | Feem pua (%) |
|---|---|
| Carbon (c) | Tsawg dua los yog sib npaug rau 0.08 |
| Manganese (mn) | Tsawg dua los yog sib npaug rau 2.00 |
| Phosphorus (p) | Tsawg dua los yog sib npaug rau 0.045 |
| Sulphur (s) | Tsawg dua los yog sib npaug rau 0.030 |
| Silicon (si) | Tsawg dua los yog sib npaug rau 1.00 |
| Chromium (cr) | 18.0–20.0 |
| Npib tsib caug (ni) | 8.0–11.0 |
TPPTPI04 Yeeb Nkab Cov Khoom Siv (raws li ATTM A312)
| Ntiag tug | Qhov toob kas |
|---|---|
| Lub zog tensile | Ntau dua los yog sib npaug rau 515 MPa (75 KSI) |
| Tos lub zog (0.2%) | Ntau dua los yog sib npaug rau 205 MPa (30 ksi) |
| Elongation | Ntau dua los yog sib npaug rau 35% (hauv 50 hli) |
| Kev nyuaj | Tsawg dua los yog sib npaug rau 90 teev |
Kav Pipes hauv A312 yuav tsum tau dhau los:
Flattening thiab dabtsi yog khoov xeem
Hydrostatic lossis tsis yog-kev sim ua phem (ndt)
Kev kuaj pom thiab sab nraud kuaj
Cov ntawv thov ntawm Astm A312 Tp3ik
Tshuaj Lom Neeg Siv Khoom Siv Hluav Taws Xob
Cov Khoom Noj Khoom Haus Thiab Dej Haus
Kws ntsuam xyuas cov tshuab raj
Roj Thiab Cov Kev Kis Roj
Cov Qauv Architecture thiab Handrails
Dej Kho thiab Devalination Nroj Tsuag
Vim nwsversatility, A312 TPP34 tau siv dav hauv ob qho tib siKev lag luam thiab kev ua kom huv.
