On the other hand, the correct installation of these products requires a highly qualified workforce: in fact, welding and joints are present in large quantities and can be considered, if not done correctly, a significant weak point for the lifetime of the pipeline.[\/vc_column_text][\/vc_column][\/vc_row][vc_row css_animation=”” row_type=”row” use_row_as_full_screen_section=”no” type=”grid” angled_section=”no” text_align=”left” background_image_as_pattern=”without_pattern” z_index=””][vc_column][vc_separator type=”small” position=”left” width_in_percentages=”yes” width=”50″][\/vc_column][\/vc_row][vc_row css_animation=”” row_type=”row” use_row_as_full_screen_section=”no” type=”grid” angled_section=”no” text_align=”left” background_image_as_pattern=”without_pattern” z_index=””][vc_column]
