cwc paip koting Proses bilong wokim

(1) Redim pes

Aplikesen bilong3LPE anti-korosen koting(FBE primer + adhesive + polyethylene topcoat)

Wokim graun i kamap strong long mekim simen i pas gut

(2) Putim ol samting bilong strongim
Ol i putim ol 'steel mesh' o 'wire cages' klostu long paip

Ol i putim ol 'polypropylene fibers' bilong strongim 'crack resistance'

(3) Konkrit Aplikesen
Hevi Konkrit Weit Koting: Dens konkrit ol i putim wantaim ol 'controled aggregates'

Impingement Concrete Weight Coating (ICWC): Simen we ol i putim long rot bilong 'impingement', na i kisim bikpela strong na densiti

(4) Putim Anode
Long lukautim gut korosen, ol i save putim ol 'sacrificial anodes' o 'impressed current anodes' insait long ol 'CWC-coated pipelines:

Ol kain anode: Aluminium, zinc, o MMO (Mixed Metal Oxide) anode

Putim:I stap insait long CWC leia na i pas long paip long lektrik

Wok: Em i save givim 'cathodic' proteksen long solwara na ples tais, na i save mekim paiplain i stap longpela taim inap 20-40 yia

(5) Kurim na Pinisim
Gutpela wok bilong strongim simen long kisim strong bilong masin

Chamfering o beveling bilong ol paip pinis bilong mekim wok welding i kamap isi.

DispelaCWC paip koting prosesem i no "putim simen" tasol. Kwaliti autkam i save kamap long rot bilong strongim fit-ap, kontrol bilong strongim, na pinisim pinis-bikos planti hevi bilong fil i save kamap olsem bagarap long arere, bruk, o nogut senis long ol pinis bilong simen-fri.

Redim pes na konfemesen bilong 'base coating': anti-korosen leia i bin sekim pastaim long putim simen.
Putim strong: sekim ples bilong 'mesh' na 'cage' bai simen i no ken bruk aninit long ol hevi.
Aplikesen bilong simen: wokim-ap long 'thickness' we yu makim wantaim 'controled compaction'.
Kontrolim 'curing': i stopim ol 'brittle edges' na 'cracking' hariap taim ol i karim.
Pinisim pinis: simen-fri pinis na klinpela senis bilong weldim (taim i gat nid).

Ol samting bilong masin na lukautim

Negative Buoyancy: Em i mekim ol paiplain i stap aninit long wara na i stap gut insait long wara o ples tais, na i daunim gut ol paiplain i kam antap long wara.
Proteksen bilong masin: Ol samting bilong lukautim yu long ol samting nogut olsem ol 'anchor drags', ol 'trawling gear', na ol samting we i save bagarapim yu taim yu putim o operetim.
Abrasion Resistance: Em i save karim bagarap taim solwara i senis, solwara, na taim em i pas wantaim ol ston o ol samting we i save bruk.
Resistans bilong bruk: Reinforced concrete i save sanap strong long 'bending', 'handling stress', na ol hevi bilong wok na i no bruk.
Opsenel Themal Insulation: Em i save bungim ol narapela leia long lukautim tempereja bilong wara insait long ol dip wara na ol ples aninit long solwara.

Field Joint & Welding Compatibility – Ol i wokim bilong wokim long solwara

Long wanpela ofso spred, CWC paip em i "gutpela" tasol sapos emi no save daunim welding na 'field joint coating'. Simen i save lukautim paip long as bilong solwara, tasol sapos ol i no redim gut ol arere bilong en, ol wokman i save westim planti aua long brukim simen, stretim ol bagarap long arere, na wok gen long fil join-stret long hap we 'schedule risk' na 'rejection risk' i stap antap tru.

Q1 - Bilong wanem yusim simen weit koting long ol paiplain long solwara?

A: Hevi bilong simeni putimnegatif buoyancyna i kamap gutpela moalong-bottom stebiliti, i helpim paiplain long sakim 'upplift' long ol 'current' na weiv na i stap gut long as bilong solwara.

Q2 - Hau bai yu makim CWC 'thickness' na 'density'?

A:Ol i makim ol bihainim makhevi i stap aninit long wara, ol mak bilong stap strong, dip bilong wara/karent, rot bilong putim, na sistem bilong putim (FBE/3LPE/3LPP), olsem na lain i inapim ol mak bilong stap gut na i no gat bikpela pe.
