1. Cov Qauv Txheej txheem cej luam
Txheem:ASTM A325 -Txheem Cov Qauv Kev Qhia Rau Cov Tsiaj Ntawv Bolts, Hlau, Kho Thaum Tshav Kub, 120/105 KSI Yam Tsawg Npaum Tensile Lub Zog
Lub hom phiaj:Siab - Lub Zog Bolts rau cov qauv hlau sib txuas hauv cov choj, vaj tse, thiab cov qauv kev lag luam.
2. Bolt hom
ASTM A325 Bolts tau faib ua peb hom:
| Ntaus | Khoom siv / Feature | Raug |
|---|---|---|
| Hom 1 | Carbon Steel, ua cua sov | Feem ntau rau cov qauv hlau |
| Hom 3 | Huab Cua Hlau (Corrosion - tsis kam) | Cov qauv sab nraum zoov, txuas hniav, thiab ib puag ncig corrosive |
3. Cov Khoom Siv Kho Tshuab
| Ntiag tug | Tus nqi |
|---|---|
| Yam tsawg kawg tensile lub zog | 120 ksi (827 MPa) |
| Yam tsawg kawg nkaus xwb Zog | 105 Ksi (724 MPA) |
| Pov Thawj Thauj | Txhais ib qho ASTM A325 qauv raws li cov ntsia hlau hla |
4. Balt Qhov Ntev
Inch:1/2 "- 1-1 / 2" (12.7 hli - 38.1 hli)
Xov:UNC (Unified National coarse)
Ntev:Raws li yuav tsum tau siv cov ntawv thov
5. Nto / Txheej
Liab qab (tiaj) hlau
Kub - dip galvanized
Neeg Kho Tshuab Zinc Plating
Kev xaiv Wubleing hlau (ntaus 3) rau sab nraum zoov / Corrosive Applications
6. Neeg rau thiab tshuab ntxhua khaub ncaws
Feem ntau ua khub nrogASTM A563 txiv ntoo
Cov tshuab ntxhua khaub ncaws ua rawsASTM F436
Ua kom paub meej clamping yuam thiab load faib
7. Cov Ntawv Thov Tib Neeg
Tus choj
High -} Rose vaj tse
Muaj Cov Qauv Steel
Ib qho txheej txheem thov qhov twg siab - Lub zog Bolting yog yuav tsum tau
