Nws integrates lub zog, hnav tsis kam, thiab seem stability.GNEE RAILkhoom siv hauv GB 8–60 kg/m, UIC50/54/60, DIN536 A55–A120, QU70/80/100/120, JIS 15KG–CR100, AS{14}}–89 kg, BS11:1985, thiab kev txhawb nqa ceev, AREMA thiab CE kev koom ua ke.
Dab tsi yog qhov txawv ntawm GB Rail thiab ASCE Rail?
Qhov sib txawv ntawm GB (Suav) rails thiab ASCE (American) rails nyob rau hauv cov qauv, qhov ntev, qhov hnyav kev faib tawm, qib steel, thiab cov ntawv thov, xav txog qhov sib txawv hauv kev tsim kho tsheb ciav hlau ntawm Tuam Tshoj thiab Tebchaws Meskas. Nov yog qhov kev sib piv ntxaws:
1. Cov Txheej Txheem thiab Cov Txheej Txheem Txheej Txheem
- GB Rails:Kev tswj hwm los ntawm Suav cov qauv hauv tebchaws (GB / T series), piv txwv li, GB / T 11264-2012 rau cov tsheb ciav hlau lossis GB / T 8162-2018 rau cov tsheb ciav hlau hnyav. Cov qauv no qhia txog qhov ntev, qib steel, cov khoom siv kho tshuab, thiab kev tsim khoom ua kom haum rau Suav kev tsheb ciav hlau thiab kev lag luam.
- ASCE Rails:Raws li AREMA (American Railway Engineering thiab Maintenance- ntawm- Txoj Kev Koom Tes) / ASCE cov lus qhia, qhia qhov hnyav ntawm kev tsheb ciav hlau hauv phaus ib yard (lb / yd), cov khoom siv, thiab kam rau ua. AREMA / ASCE rails yog siv nyob rau hauv North America thiab cheeb tsam tom qab US railway coj.
2. Chav ntsuas thiab qhov hnyav
GB Rails:Qhov hnyav yog ntsuas hauv kg ib 'meter'. Piv txwv li:
- Lub teeb rail: 22 kg / m (GB 22 kg)
- Heavy rail: 50 kg / m (tus qauv tseem ceeb)
| Kev faib tawm | Qhov siab (mm) | Lub taub hau (mm) | Hauv qab (mm) | Thickness (mm) | Qhov hnyav (kg / m) | |
| Lub Teeb Rail | 8 KG / M | 65 | 25 | 54 | 7 | 8.42 |
| 9 KG / M | 63.5 | 32.1 | 63.5 | 5.9 | 8.94 | |

| 18 KG / M | 80 | 40 | 80 | 10 | 18.06 | |
| 22 KG / M | 93.66 | 50.8 | 93.66 | 10.72 | 22.3 | |
| 24 KG / M | 107 | 51 | 90 | 10.9 | 24.46 | |
| 30 KG / M | 107.95 | 60.33 | 107.95 | 12.3 | 30.1 | |
| Heavy Rail | 38 KG / M | 134 | 68 | 114 | 13 | 38.733 |
| 43 KG / M | 140 | 70 | 114 | 14.5 | 44.653 | |
| 45 KG / M | 145 | 67 | 126 | 14.5 | 45.546 | |
| 50 KG / M | 152 | 70 | 132 | 15.5 | 51.514 | |
| 60 KG / M | 176 | 73 | 150 | 16.5 | 60.64 | |
| Crane Rail | qw 70 | 120 | 70 | 120 | 28 | 52.8 |
| qw 80 | 130 | 80 | 130 | 32 | 63.69 | |
| QU 100 | 150 | 100 | 150 | 38 | 88.96 | |
| qw 120 | 170 | 120 | 170 | 44 | 118.1 | |
ASCE Rails:Qhov hnyav yog ntsuas hauv lb/yd. Piv txwv li:
- 90 lb/yd (~ 44.7 kg/m)
- 115 lb/yd (~ 57 kg/m)

| TIAB SA 175 | 109.86 | 152.4 | 152.4 | 38.1 | 86.8 | |
Qhov sib txawv hauv chav tsev no tseem cuam tshuam rau cov lus pom zoo, xws li lub taub hau dav, lub hauv paus dav, thiab kev tsheb ciav hlau qhov siab.
3. Rail Dimensions thiab Profiles
- GB Rails:Lub taub hau, lub vev xaib, thiab lub hauv paus qhov ntev yog txhais ua millimeters. Piv txwv li, GB 22 kg lub teeb rail: taub hau 50.8 hli, qhov siab 93.66 hli, hauv paus 93.66 hli. Heavy rails (piv txwv li, 50 kg / m) muaj lub taub hau ~ 65 hli thiab qhov siab ~ 135 hli.
- ASCE Rails:Dimensions yog nyob rau hauv nti, nrog profiles muaj npe raws li qhov hnyav. Piv txwv li, 115 lb / yd rail: taub hau 2.875 hauv (73 mm), qhov siab 6.25 hauv (159 mm), puag 6.5 hauv (165 mm).
Raws li tus kws tshaj lij rail fastener tsum,GNEE RAILtuaj yeem muab cov qauv hlau sib txawv xws li GB, Asmeskas, BS, UIC, DIN, JIS, Australian thiab South Africa uas siv hauv kev tsheb ciav hlau, cranes thiab thee mining.
