Profesenel Konkrit Weit Koting Saplaia bilong yu
Octal Pipe em i wanpela profesenel na integreted saplaia bilong ol oilfil prodak na indastriel stiel solusen we i stap long Saina. Mipela i gat bikpela save long saplaim, tilim, na wokim ol samting, na mipela i save givim planti kain kain ain samting bilong oil na ges, eneji, na indastriel sekta.
Bilong wanem yu mas makim mipela
Gutpela Kwaliti Asurens
Ol 'steel pipe' bilong mipela i save go insait long strongpela tes na bihainim ol intanesenel standet, na dispela i save mekim ol i stap longpela taim tru, ol i no inap bagarap, na ol i wok gut long ol bikpela hevi.
Ol setifiket
Olgeta prodak i gat ful materiel trasebiliti, ol setifiket bilong mil, na bihainim ol intanesenel standet olsem API, ASTM, ASME, EN, na ISO.
Kompetitiv Prais
Mipela i save givim ol 'premium-greid steel paip long gutpela prais, na mekim gutpela pe long rot bilong gutpela wok bilong wokim na saplai sen menesmen na i no bagarapim kwaliti bilong en.
Kwik na gutpela deliveri
Mipela i yusim gutpela 'sea freight logistics' na wanpela 'global network', na mipela i save mekim ol 'steel paip' i go long solwara long taim stret, na daunim ol delei na mekim wok bilong yu long taim stret.
Hevi bilong simen
Concrete weight coating (CWC) em i wanpela 'plant-aplyed reinforced concrete coating system we ol i save putim ausait long yusim 'impingement' o 'compression' (wrap) rot long 'bare pipe' o 'pre-coated offshore pipe wantaim minimam tiknes bilong 25mm, we ol i wokim pastaim long sabmerge sevis bilong wara o oillain sistem.
As tingting bilong wanpela simen weit koting em long givim 'negative buoyancy' long paiplain, na mekim paiplain i stap gut long solwara, na/o long givim moa 'mechanical protection' long paip na 'anti-corrosion coating' bilong en taim ol i putim na long taim paiplain i wok.

Durability
Simen i save stap longpela taim tru, na i save lukautim ol paiplain longpela taim long taim nogut bilong envairomen.
01
Gutpela Kontrol bilong Hevi
Simen koting i givim wanpela gutpela na stretim rot bilong bosim 'buoyancy', moa yet long ol paiplain long solwara na aninit long solwara.
02
Impact Resistance
Simen koting i save lukautim paip long bagarap bilong masin, na i save daunim hevi bilong bagarap taim ol i karim na putim.
03
Kost-Gutpela Solusen
Simen em i no gat bikpela pe tumas winim ol narapela samting bilong putim hevi long en, na dispela i mekim na em i wanpela gutpela samting long ol paiplain aplikesen we ol i mas bosim hevi bilong en.
04
