3　Basic Requirements

3.0.1　The specifications of mill sets for producing high frequency longitudinal welded pipe（ERW），spiral submerged-arc welded pipe（SSAW）and stainless steel continuous welded pipe（EFW）should be selected on the basis of Table 3.0.1.

Table 3.0.1　Specifications of Mill Sets for Production of ERW，SSAW and EFW Pipes

Note:ERW in the above Table 3.0.1 refers to the mill set for production of high frequency longitudinal welded pipes，SSAW the mill setfor production of spiral submerged-arc welded pipes，and EFW the mill set for production of stainless steel continuous welded pipes.

3.0.2　The mill set for production of longitudinal submerged-arc welded pipes should be installed nearby the wide/heavy plate mill set where supply of feedstock is guaranteed.
