The SPO compact flange has been used across the globe since 1989, offshore, onshore and subsea, offering significant weight and space savings over conventional flanges, leak-free joint integrity and therefore is the most effective environmentally friendly piping joint available today.
The preferred method of tightening the SPO compact flange bolts is with the use of bolt tensioning tools. Due to the compact size and relatively high bolt load requirements of the flanges, most conventional bolt tensioners either do not physically fit onto the flanges or do not have enough bolt load capacity.
The V-Series tensioners are a purpose designed range of tools for use on SPO compact flanges. The range consists of 11 powerful bolt tensioning tools covering bolt sizes from 3/4" to 4".
