TSUH (Speed-head Wellhead)

The TSUH speed head system takes multi-bowl technology one step further than ever before. By landing two strings of pipe in one compact forged housing. The TSUH system eliminates one complete BOP nipple-down/nipple-up thereby saving significant rig time. The TSUH wellhead improves safety compared to conventional wellheads by reducing the number of potential leak paths.
