Durable Spiral Welded Steel Pipe

Tlhaloso e Khutšoanyane:

Peipi ea rona ea tšepe e tšoarellang ea spiral welded e etselitsoe ho mamella mathata a lipalangoang tsa likhoerekhoere le metsi a litšila. Kaho ea eona e matsutla e tiisa matla a holimo le bophelo bo bolelele, e e etsa khetho e nepahetseng bakeng sa merero ea meralo ea motheo e hlokang ho ts'epahala le ho sebetsa hantle.
