Tshuaj muaj pes tsawg leeg
Cov tshuaj muaj pes tsawg leeg rau ASTM A53 ERW Yeeb Nkab yog tus qauv los xyuas kom meej weldability thiab kev ua tau zoo.
Qhov feem pua siab tshaj plaws rau cov ntsiab lus tseem ceeb yog raws li hauv qab no:
| Lub ntsiab | Qib A, max (%) | Qib B, max (%) |
|---|---|---|
| Cov pa roj carbon (C) | 0.25 | 0.30 |
| Manganese (Mn) | 0.95 | 1.20 |
| Phosphorus (P) | 0.05 | 0.05 |
| Sulfur (S) | 0.045 | 0.045 |
| Copper (Cu) * | 0.40 | 0.40 |
| Nickel (Ni) * | 0.40 | 0.40 |
| Chromium (Cr) * | 0.40 | 0.40 |
| Molybdenum (Mo) * | 0.15 | 0.15 |
| Vanadium (V) * | 0.08 | 0.08 |
* Ceeb toom: Tag nrho cov muaj pes tsawg leeg rau tsib alloying ntsiab (Cu, Ni, Cr, Mo, V) yuav tsum tsis pub tshaj 1.00%. cov
Mechanical Properties
Qhov tseem ceeb ntawm qhov sib txawv ntawm Qib A thiab Qib B yog nyob rau hauv lawv lub zog txhua yam, ua rau Qib B yog qhov kev xaiv rau siab dua - kev siv kev ntxhov siab. cov
| Khoom | Qib A, yam tsawg kawg nkaus | Qib B, yam tsawg kawg nkaus |
|---|---|---|
| Tensile zog | 48,000 psi (330 MPa) | 60,000 psi (415 MPa) |
| Yield zog | 30,000 psi (205 MPa) | 69,000 psi (240 MPa) |
Kev kho deg thiab ua tiav
ASTM A53 ERW kav dej muaj nyob rau hauv ntau qhov chaw tiav kom haum rau ib puag ncig sib txawv:
Dub Hlau (Uncoated):
Features tsaus oxide tiav los ntawm kev tsim khoom.
Zoo tagnrho rau kev siv sab hauv tsev, qhov chaw qhuav, lossis qhov chaw ntxiv txheej yuav raug siv rau ntawm -site.
Feem ntau siv nyob rau hauv cov roj kab, hluav taws kub sprinkler systems, thiab cov qauv kev txhawb nqa.
Kub-Dip Galvanized (HDG):
Coated nrog ib txheej tiv thaiv zinc los ntawm kub -dip galvanizing.
Muab superior tiv thaiv xeb, noo noo, thiab atmospheric corrosion.
Haum rau kev teeb tsa sab nraum zoov, siv hauv av, thaj chaw ntub dej, laj kab, thiab kev ua liaj ua teb irrigation.
Lus Cim: Cov kav dej galvanized yuav tsum tsis txhob siv rau hauv siab - daim ntawv thov kub (siab dua 390℃F / 200 degree) vim tias cov zinc txheej yuav degrade.
Lwm yam Coatings:
Oiled, dub pleev xim rau, los yog varnished nto muaj nyob rau hauv kev thov
Qhov zoo ntawm ASTM A53 ERW Pipe
Tus nqi -Kev ua tau zoo: ERW yog qhov ua tau zoo dua thiab tsis tshua kim tshaj qhov kev tsim cov yeeb nkab seamless, muab kev txuag nyiaj rau cov haujlwm loj -.
Zoo ib yam:ERW thev naus laus zis tsim cov phab ntsa tuab tuab thiab du weld seams, txhim kho cov yam ntxwv ntws thiab kev ua haujlwm zoo.
Dav Muaj:Yooj yim muaj nyob rau hauv ntau qhov ntau thiab tsawg thiab cov sij hawm, yooj yim rau kev yuav khoom sai thiab ua tiav qhov project.
Yooj yim ntawm Fabrication:Cov weldability zoo heev thiab formability tso cai rau yooj yim khoov, threading, thiab coupling ntawm -site.
Standardization:Ua raws li cov qauv thoob ntiaj teb, ua kom muaj kev sib raug zoo nrog cov khoom siv thoob ntiaj teb thiab cov txheej txheem kev sib txuas.
