I-Deameter enkulu ye-WelDed Pipes Teel Tabler

I-Deameter enkulu ye-WelDed Pipers yentsimbi ye-tubular i-piles ibonisa umfanekiso

Inkcazo emfutshane:

Siyavuya ukuqalisa i-Steel SAIDS yensimbi yensimbi, eyilelwe ukubonelela ngokugqibeleleyo kwezicelo ezahlukeneyo, ngakumbi iikopi. Ezi piles zibonisa uyilo olujikelezayo okanye olujikelezileyo lwesandla samandla angenakuthelekiswa nanto kwaye sibambelele kwaye sithintele i-ingeress yamanzi, umhlaba kunye nesanti.
