Qhov zoo ntawm ERW txheej txheem
Siab qhov tseeb- Kev tswj nruj ntawm OD, phab ntsa tuab, ovality; tau tshaj Ringlock, Cuplok, thiab ncej scaffolding fittings.
Txhim khu kev weld zoo- Siab- zaus induction vuam + online eddy tam sim no / kuaj ultrasonic.
Ntxim qab- Tsis muaj kauv vuam (tsis zoo li LSAW / SSAW), yooj yim rau galvanizing thiab sib dhos.
Tag nrho traceability-Txhua cov yeeb nkab tuaj yeem raug cim nrog qib, tus lej xov tooj cua sov, thiab tus lej batch.
Nto Finish & Corrosion Protection
| Ua kom tiav | Yam ntxwv | Ib puag ncig tsim nyog |
|---|---|---|
| Bare (xeb tiv thaiv roj) | Tus nqi qis, luv - siv sijhawm | Sab hauv, tej yaam num ib ntus |
| Kub-dip galvanizing (HDG) | Corrosion resistance Ntau tshaj los yog sib npaug rau 20 xyoo | Sab nraum zoov, ntub dej, ntug dej hiav txwv |
| Electro-galvanized / Painted | Cov tsos zoo, kev tiv thaiv nruab nrab | General sab nraum zoov, tso saib cov qauv |
| Epoxy txheej | Tshuaj tiv thaiv, muaj zog adhesion | Cov nroj tsuag tshuaj, kev kho dej khib nyiab |
Kev sib piv: S355J0H vs Common Scaffolding Pipes
| Khoom | S355J0H | Q235B | Q355B |
|---|---|---|---|
| Yield zog (MPa) | Ntau dua lossis sib npaug rau 355 | Ntau dua lossis sib npaug li 235 | Ntau dua lossis sib npaug rau 355 |
| 0℃cuam tshuam (J) | Ntau dua lossis sib npaug 27 | Tsis tau lav | Tsis tau lav |
| Haum rau qhov kub thiab txias | ✅ Yog | ❌ pluag | ❌ pluag |
| Weldability | Zoo | Zoo | Ncaj ncees |
| Kev lees txais thoob ntiaj teb | Siab (EN) | Tsawg | Nruab nrab |
