Main features and applications |
|
||||||||||
|
1) Used for the transportation of water (not water supplies), air, steam, oil, gas, and other fluids at relatively low pressures. 2) Two different kinds: black pipe and white pipe. Operating temperature range: -15 to 350°C. 3) MZN grade groove corrosion-resistant ERW steel pipe is also sold, for protection against the groove corrosion that may occur along the welds of ERW steel pipe. |
