Product Overview
KASI supplies a full range of hydraulic bolt tensioning equipment for rent and sale across Canada and Alberta. From topside bolt tensioners to hydraulic tensioning nuts, bolt tensioner components, and hydraulic pumps, we provide complete solutions for safe and accurate bolt tensioning in oil & gas, petrochemical, subsea, and power generation industries.
Our hydraulic bolt tensioners are manufactured from the highest quality materials, ensuring precision and durability even under 1500 bar operating pressure. Designed to provide uniform preload across bolted connections, they eliminate friction losses common with torque tightening methods.
KASI offers:
- Topside Bolt Tensioners
- Bolt Tensioner Components
- Hydraulic Tensioning Nuts
- Bolt Tensioner Hydraulic Pumps
Whether your project requires temporary rentals during shutdowns or permanent equipment purchases, KASI delivers complete bolt tensioning systems tailored to your needs.

What is bolt tensioning and why is it important?
Bolt tensioning is a method of applying accurate preload to bolts by stretching them with hydraulic force. It provides greater accuracy and uniform clamping force compared to torque tightening, reducing the risk of joint failure.
What types of bolt tensioners does KASI offer?
We offer topside hydraulic bolt tensioners (spring-assisted & manual), hydraulic tensioning nuts, and complete tensioner kits with pumps and components.
What are bolt tensioner components?
These include seals, bridges, pullers, reaction nuts, and accessories, which ensure long service life and reliable performance of tensioning equipment.
What role do hydraulic pumps play in bolt tensioning?
Bolt tensioner hydraulic pumps provide the required high-pressure power to operate tensioners. They are available in manual, electric, or air-driven versions depending on the application.
Can I rent bolt tensioning equipment in Canada and Alberta?
Yes. KASI rents and sells bolt tensioners, tensioning nuts, hydraulic pumps, and components across Canada, with local distribution and support from Edmonton, Alberta.
