Bolt-tensioning, equipment firm Tentec is showcasing its new V-Series of compact flange bolt tensioners. The V-Series is a range of tools designed for use on SPO compact flanges and the Norsok L-005 compact flanges. The range consists of 11 bolt tensioning tools covering bolt sizes from ¾-4in. Tentec says the preferred way to tighten SPO compact flange bolts is by using bolt-tensioning tools, but, due to the small size and relatively high bolt-load requirements of the flanges, many conventional bolt tensioners either do not fit or do not have a high enough bolt-load capacity.
