Tsebisa:
Lefatšeng la kaho le nts'etsopele ea meaho, ho bohlokoa ho khetha thepa e nepahetseng.Liphaephe tsa sebopeho sa karolo e se nang letho phetha karolo ea bohlokoa ho fana ka matla, nako e telele le ho tšepahala mererong e fapaneng.Ho blog ena, re tla hlahloba litšoaneleho le melemo ea mefuta e 'meli ea bohlokoa ea phala ea meralo: pipi e kentsoeng ka tlas'a metsi arc welded pipe le API 5L line pipe.
Spiral submerged arc welded pipe:
Pipe ea submerged arc welded (SAW), eo hape e tsejoang e le phala ea SSAW, e sebelisoa mefuteng e mengata ea lits'ebetso.Tšobotsi e ikhethang eaPipe ea SSAW ke li-spiral seams, tse fanang ka matla a maholo le bokhoni ba ho jara mojaro ha li bapisoa le mefuta e meng ea liphaephe.Moqapi ona o ikhethang o thusa ho aba khatello ea kelello ka ho lekana ho pholletsa le phala, ho etsa hore e be e loketseng bakeng sa merero e hlokang botšepehi ba sebopeho.
