Ntlafatso ea Meaho ea Likhoerekhoere ka ho Sebelisa Liphaephe tsa Spiral Submerged Arc (SSAW)

Tlhaloso e Khutšoanyane:

Karolo ena ea Tekanyetso ea Europe e totobatsa maemo a tekheniki a phano bakeng sa likarolo tse batang tse cheselitsoeng, tse se nang letho tsa libōpeho tse chitja, tsa lisekoere kapa tse khutlonnetsepa, 'me e sebetsa likarolong tse entsoeng ka masoba tse batang ntle le ho phekoloa ka mocheso o latelang.

Cangzhou Spiral Steel Pipes Group Co., Ltd e fana ka karolo e se nang letho ea liphaephe tse chitja tsa tšepe bakeng sa sebopeho.
