Spring Return Hydraulic Bolt Tensioner

Our Spring Return Hydraulic Bolt Tensioners are designed for fast, efficient, and safe bolting operations in critical applications such as oil & gas, power generation, and petrochemical industries. The spring-assisted return system ensures the piston automatically retracts after each tensioning cycle, significantly reducing manual effort and speeding up operations compared to standard tensioners.

Built from high-strength alloy steel, these tensioners deliver consistent performance even in harsh environments. Their compact design allows easy use in restricted or confined spaces, while the precision-engineered load cells guarantee accurate and repeatable bolt tensioning.

Key benefits include:

• Automatic piston retraction for faster cycle times and reduced downtime.
• Wide compatibility with various bolt sizes and stud dimensions.
• High safety factor with over-stroke protection and leak-resistant seals.
• Durable construction suited for long-term use in offshore and onshore operations.

With a range of models available, our Spring Return Hydraulic Bolt Tensioners provide a reliable solution for achieving uniform bolt load, ensuring joint integrity and minimizing the risk of leakage or failure
