Process:
SAW (SAWL, SAWH): Spiral Welded
SSAW: Spiral Submerged-arc Welded
Application: Our SSAW pipes can be used as steel penstock for using in natural gas, chemical, electric power, heating power, water supply and drainage, steam heating, and hydropower industries, and are also ideal for long distance transferring of water and any other non-corrosion liquid materials. In addition, they can also be used steel structure projects and the fields for piling, dredging and bridge construction, etc.
