I-China ingenamthungo ngomkhiqizi wamapayipi we-hot-dip galvanized kanye nomhlinzeki

Umthungo wepayipi elishisayo elishisayo

Umthungeli nge-Hot-Drips Pipled Pipe efakiwe

Incazelo emfushane:

Amapayipi ensimbi angenamthungo e-General Inhloso Steam, Amanzi, igesi kanye nemigqa yomoya ngaphakathiI-ASTM A53 / A53M-2012Standard.

e = ubuncane be-gauge 2in. (50mm), amaphesenti ayindilinga asondele ku-0.5% aseduze;
