Usoro nrụpụta ọkpọkọ API 5L Welded steel
Ụdị 1. Spiral Welded: Spiral welded ígwè ọkpọkọna-arụpụtara site spirally ịgbado ọkụ a warara nke ígwè, na-akpụ a helical onuete. Usoro a na-enye ohere maka ịmepụta nnukwu ọkpọkọ dayameta ma na-adịkarị ọnụ ahịa maka ụfọdụ ngwa.
Mkpuchi na Ọgwụgwọ:Iji kwalite nguzogide corrosion na ịdịte aka, ọkpọkọ ndị a nwere ike ịme mkpuchi na usoro ọgwụgwọ dị iche iche, dị ka fusion bonded epoxy (FBE) ma ọ bụ mkpuchi polyethylene atọ (3LPE).
Ụdị 2. Mgbado ọkụ ọkụ eletrik (ERW):A na-ekpo ọkụ n'ọnụ ọnụ nke eriri ígwè a kpụrụ site na iji nguzogide eletrik. Mgbe ahụ, a na-etinye nrụgide iji jikọta ọnụ ọnụ ọnụ, na-emepụta weld siri ike na-enweghị mkpa maka ihe mkpuchi.
Ụdị 3.Mgbado ogologo ogologo:
Arc Welding Submerged (SAW): A na-ejikọta ọnụ ọnụ ọkpọkọ a kpụrụ akpụ site na iji usoro ịgbado ọkụ nke submerged arc, nke gụnyere iji arc eletrik na granular flux na-emepụta ihe dị elu, nke siri ike.
Ugboro abụọ Arc Welding (DSAW): Maka ọkpọkọ ndị buru ibu, a na-agbakọta ma ime ma n'èzí, na-eme ka ntinye na ike zuru oke.
