Diskripsen bilong prodak
ASTM A53 em i wanpela standet spesifikasen bilong kabon stiel paip long ol liklik paip sais, we ol i wokim bilong karim wara, ges, win, stim na bilong ol jeneral mekanik na straksel yus. Em i karamapim ol paip we i no gat rop, ERW welded paip na furnace-butt welded paip, long tupela strong level (Gred A na Gret B).
Octal Pipe i save saplaim ASTM A53 Gret A na Gret B wantaim opsenel galvanising, kain kain pinis, na ful mil setifikesen bilong projek deliveri.
Ol kain prodak
- Taip S – I no gat mak
Hot-pinis o kol-pinis seamles paip. Em i gutpela long ol presa sistem, ol yutiliti bilong plent na ol masin sevis we ol i mas i gat wankain wol.
- Taip E – ERW (Elektrik-Resistans Welded)
Paip we ol i weldim longpela taim wantaim hat bilong weld-ol i tritim olsem spesifikesen i tok. Wanpela kos-efisien jois bilong ol fluid lain, paia sistem na ol straksel aplikesen.
- Taip F – Furnace-Butt Welded
Em i stap long Gret A tasol. Yusim long lait-diuti sevis we spesifikasen i larim dispela proses.
- Ol mak
Gret A:standet strong bilong jeneral sevis
Gret B:bikpela 'tensile' na 'yield strength', planti taim ol i save yusim long presa na ol masin

Ol samting bilong masin
| Banis | Gret A | Gret B | Ol toksave |
|---|---|---|---|
| Strong bilong holim | Bikpela o wankain olsem 330 MPa (48 ksi) | Bikpela o wankain olsem 415 MPa (60 ksi) | Strong bilong paip olgeta |
| Strong bilong givim | Bikpela o wankain olsem 205 MPa (30 ksi) | Bikpela o wankain olsem 240 MPa (35 ksi) | Presa / strong bilong straksa |
| Longpela | Bikpela o wankain olsem 30% | Bikpela o wankain olsem 30% | Em i gutpela long 'threding', 'bending', 'fabrication' |
Gret B, wantaim bikpela 'tensile' na 'yield' veliu, em i nambawan samting bilong ol 'pressure line', 'fire system' na 'mechanical service'.
Wok bilong wokim samting na bosim wok bilong en
ASTM A53 i larim tupela rot we i no gat 'seam' na 'welded'. Ol paip we i no gat 'seams' em ol i save wokim long hat na sais bilong en i stret long OD na 'wall thickness'. Ol ERW paip i mas gat gutpela weld i go het; hap bilong weld i kisim hat-tritmen taim ol i tok klia olsem na 'untempered martensite' i no stap. Furnace-butt welded pipe em i mak bilong Gret A tasol.
Olgeta longpela bilong paip i stap aninit long:
- lukluk na skelim long sait bilong stretpela, OD, wol na pes
- haidrostatik tesotok orait long non-eksamin we i no inap bagarapim
- bend/flattening tes bilong ol weld prodak long konfemim weld kwaliti
Dispela level bilong kontrol i mekim A53 i orait long yusim wara, ges na straksa sevis insait long ol bilding, plent na ol yutiliti.

Hot-Dip Galvanized Opsen
Ol paip bilong ASTM A53 ol i ken putim long hot-dip galvanisim long rot bilong putim insait long wara. Zinc i mas inapim ASTM B6, na hevi bilong 'coating' i no ken stap aninit long ol mak we i stap insait long ASTM A53. Dispela 'coating' i mas stap oltaim, na i no gat ol liklik mak, ol liklik sua na ol pipia.
Galvanized A53 em i gutpela long yusim long ol lain ausait, wara na win sevis, paia we i stap ples klia, na ol indastrial envairomen we i nidim gutpela 'corrosion resistance'. Octal Pipe i ken saplaim ol blakpela na ol 'galvanized' paip long wankain sais, wantaim 'coating verification'.
