  Imported bolt tensioner   Bolt stretching tool  
Compact structure: CTST series bolt stretching tools are by far the most compact and reliable stretching tools
The unique design of our stretching tools can meet most ansi-api-miss standard pipe flanges

Safe and reliable sealing ring: the reliability of sealing ring is a basic requirement
All bolt stretching tools use polyurethane self sealing rings that do not need adjustment
Sealing ring “ Embed ” In the groove of the piston, it remains firm and will not move or fail after long-term use
The sealing ring is machined rather than formed, so the size is not limited, and no error is allowed in the design process of the stretcher

Low friction coefficient, easy recovery: the nitrile seal ring used with other hydraulic bolt tensioners has a lower friction coefficient than our seal ring
Because of this advantage, the piston recovery is easier

Overtravel indication: if the maximum stroke of the piston is exceeded, most bolt tensioners have a simple mechanical device that can export the excess liquid
When the maximum stroke of the piston is reached, a red indicating line will be seen

Connecting hose system: one of the many advantages of bolt tensioner is that it can connect multiple bolt tensioners together and stretch all bolts on a flange connection at the same time
This method can distribute the load well
We provide a simple assembly method called “ Connect the hose ”, Both ends of this high-pressure hose are equipped with male and female connectors
This method of connecting multiple bolt tensioners together is fast and simple (the number of hoses is equal to the number of bolt tensioners to be connected)
This formula is easy to remember
