Spiral welded pipes (SSAW) bakeng sa merero ea ho boloka metsi ka kakaretso ke liphaephe tsa tšepe tse entsoeng ka spiral tse nang le li-diameter tse batlang li le kholo, hobane metsi a fetang ka nako ea yuniti a maholo, a ka ntlafatsang haholo katleho ea mosebetsi.Kaha lerako le ka hare la phala ea tšepe ea spiral le lula le hlatsuoa ke metsi, lerako le ka hare ka kakaretso ha le alafshoa ka kalafo e thibelang ho bola, empa bokantle ba ka kakaretso bo ka sebopeho sa holimo, ka hona ho lokela ho etsoa anti-corrosion ho sebetsana le eona. khoholeho ea pula le ho pepesehela letsatsi, kahoo litlhoko tsa liphahlo tse thibelang kutu li phahame.

Pele ho anticorrosion ea liphaephe tsa tšepe tsa spiral bakeng sa merero ea ho boloka metsi, bokaholimo ba liphaephe tsa tšepe bo lokela ho hloekisoa ka lehlabathe, 'me sehlopha se fihle ho st2.5.Ka mor'a ho phatloha ha lehlabathe, sebelisa anti-corrosion primer hang-hang.The anti-corrosion primer ka kakaretso ke pente e nang le zinki e ngata ea epoxy e nang le zinc content ea 70% kapa ho feta, bohareng ke pente ea epoxy mica, 'me lesela le ka ntle ke anti-oxidation le corrosion.Pente ea polyurethane.

Pele o tloha fekthering, pipe ea tšepe ea spiral e lokela ho lekoa bakeng sa thepa ea mochine, ho batalla le ho phatloha, 'me e tlameha ho finyella litlhoko tsa maemo.Liphaephe tsa tšepe tse cheselitsoeng ka spiral li na le phetoho e kholoanyane lipakeng tsa bophara ba bophara le litekanyo tsa botenya ba lebota, haholo-holo tlhahisong ea liphaephe tse nang le marako a botenya, haholo-holo tse nyane le tse mahareng tse nang le marako a botenya.Ho na le litlhoko tse ling ho latela litlhaloso tsa lipeipi tsa tšepe tsa spiral.Bophara le boholo bo hlalosang phaephe ea tšepe ea spiral bo lokela ho laoloa ka mokhoa o bonolo.
