I-Botop Steel ingumkhiqizi ohamba phambili kanye nesitoko samapayipi ensimbi namashubhu e-China, sithengisa futhi sinikezela ngepayipi lensimbi eliyisiyingi elingenamthungo ukuze lisetshenziswe uketshezi kanye ne-petroleum ngosayizi osuka ku-10 OD kuya ku-660 OD ekugqimeni kuka-1mm kuya ku-100mm.Senza amapayipi ensimbi e-carbon LSAW ngokuqinile ngokwezinga lamazwe ngamazwe njenge-ASTM, API &DIN.Siphethe ipayipi likalayini elingenamthungo amathani angaphezu kuka-8000 esitokweni nyanga zonke, ngokuvamile singaletha izimpahla ngokushesha.Nokho ezimweni ezikhethekile, uma isitokwe secarbon steel amapayipiayitholakali singaletha izimpahla ngesikhathi esifushane sokulethwa ngemithombo yendawo yokugaya noma ukungenisa
Konke okwethuamapayipi ensimbikanye nemikhiqizo yamashubhu ihlinzekwa ngezitifiketi zokuhlola eziqondile ezingu-3.1, ngokuya nge-EN 10204. Isitifiketi ngokuya ngo-3.2 kungavunyelwana ngaso ngesikhathi soku-oda.Ukuhlolwa komuntu wesithathu kwamukelwe (i-BV, i-SGS, njll)
Inani elanele lokungapheleli kwendawo ebonakalayo ukuze
ukunikeza isiqinisekiso sesizini siyadingeka.
Isici kufanele sisuswe noma sinqunywe ngaphakathi
imikhawulo yezidingo ngobude .Ipayipi eliphelile
izoqondana ngokunengqondo.
