Mining bilong 'clad pipe':wanpela 'carbon-steel paip wantaim wanpela liklik 'corrosion-resistant alloy (CRA) leit we i pas long insait bilong en (klad), o wanpela seperet CRA tube we ol i putim insait long 'carbon-steel paip (i gat lain). As tingting bilong dispela em long holim CRA korosen resistens long hap we wara i tatsim, na long wankain taim holim strong na kos straksa bilong wanpela 'carbon-steel carrier.
Long oil, ges, na kemikel trenspot, korosen em i no wanpela mentenens tasol-em i makim laipspan bilong olgeta sistem. Ol 'carbon steel' paiplain bilong bipo, maski ol i strongpela long sait bilong masin, ol i save bagarap hariap taim ol i stap long 'sour-gas o solwara. Long narapela sait, yusim ol strongpela 'corrosion-resistant alloy (CRA) paip em i gutpela long sait bilong teknikel tasol em i no inap long stap gut long sait bilong mani.
Long pasim dispela hevi, ol enjinia i kamapimCRA Clad na Lined Pipe, wanpela gutpela rot bilong wokim ol samting long ain we i save bung wantaimstrong, strong bilong sakim korosen, na kos-efisiensiinsait long wanpela enjinia prodak.

Rot bilong stretim hevi: Dual-Metal Composite Concept
Long as bilong en, CRA Claded Pipe em i wanpelatupela metalik paiplain, i bungim tupela metal we i gat narapela narapela wok:
Struktural Leya (Outa Shell):Hai-greid kabon o liklik-aloi ain (olsem, API 5L X60/X65, ASTM A106, A333) i save givim strong bilong karim hevi bilong masin.
Korosen Baria (Insait Leya):Ol aloi we i gat 'nickel-' o 'stainless' olsem 316L, Inconel 625, Alloy 825, o Duplex 2205 i save kamapim wanpela gutpela 'protective lining' egensim ol CO2, H2S, na ol wara we i gat planti 'chloride'.
Dispela 'metalurgical pairing' i mekim samting we tupela metal tasol i no inap long mekim: wanpela paip we i save sanap strong long bikpela presa, tempereja, na ol samting we i save bagarapim ol samting inap planti yia, maski em i stap aninit long solwara o long ol ples we i gat planti solwara.
'clad pipe' Menufaksing na Metalurjikel Integriti
I no olsem olpela 'carbon steel', ol CRA cald paip i nidim stretpela 'bonding' namel long 'alloy layer' na 'steel substrate'. Ol rot ol i yusim i dipen long ol samting ol i nidim long mekim wok na sevis i no strong tumas:
| Kain Proses | Prinsipel bilong Pasin | Ol bikpela gutpela samting |
|---|---|---|
| Eksplosen Bonding | Kontrol detonesen i pasim CRA long ain plet na i no melt. | I wokim wanpela strongpela 'metallurgical interface' we i gutpela long ol 'thick-wall' o bikpela '-'diamita paip. |
| Weld Overlay | CRA aloi we ol i putim long rot bilong weldim long ain. | Em i mekim gutpela CRA tiknes na gutpela insait bilong ol lain i gat bikpela presa. |
| Hot Rol Bonding | CRA na base steel i rol wantaim aninit long hat na presa. | I givim wankain bon na wankain CRA adhesen bilong kamapim planti samting. |
| Mekanikal Laining | CRA tiub i go insait na skruim insait long kabon stiel paip. | Kost-i gutpela long ol aplikesen we i gat liklik presa, na i no gat swit. |
