Secure Your Flange Connections with Confidence: Introducing Our Premium Flange Tensioners
 

Tackle Standard and Demanding Applications:

Our comprehensive range of flange tensioners offers a solution for virtually any project. Standard tensioners operate at a maximum pressure of 1500 bar and are specifically designed to fit most ANSI B 16.5, 16.47, and API flanges.  For situations with limited space or exceptionally high load requirements, we also provide custom-built tensioners to seamlessly integrate with your unique needs.

Built to Last, Engineered to Perform:

These industrial-grade tensioners are constructed with a focus on durability and longevity.  Suitable surface protection ensures they can handle demanding conditions and harsh environments, delivering a long and reliable service life.

Prioritizing Safety and User Confidence:

Comprehensive Safety Manual: We prioritize user safety and provide a clear and concise Health and Safety Operating and Instruction Manual. Featuring easy-to-understand graphical illustrations, this manual details proper equipment usage, maintenance procedures, and essential operating pressure data.
Expert Support: Our team is readily available to answer any technical questions you may have regarding the equipment or its specific applications. We are committed to providing you with the information and support you need to feel confident throughout the flange tensioning process.

Understanding the Components:

The core functionality of our tensioners relies on a combination of key components:

Hydraulic Cylinder: Generates the necessary force for effective bolt tensioning.
Socket: Provides a secure connection to the specific bolt size and type.
Bridge: Creates a stable platform for optimal force distribution.
Puller: Applies the hydraulic force generated by the cylinder through the bridge and socket for tensioning.
Adaptor Set (Optional): Offers additional versatility with interchangeable sockets, bridges, and pullers for a wider range of flange configurations.

Unmatched Safety Features:

Cutting-Edge Seal Technology: We incorporate the latest seal technology to prevent leaks and ensure operational integrity. This minimizes the risk of accidents and equipment failure, prioritizing safety during every use.
Long Stroke Design: Our tensioners boast a long stroke design, allowing for efficient and precise bolt tensioning across a wider range of applications.

Our commitment to safety, reliability, and versatility makes our flange tensioners the perfect choice for your demanding bolting projects. Contact us today to discuss your specific needs and learn how our solutions can help you achieve secure and efficient flange connections.

 

FAQs

The tensioner plays a crucial role in maintaining the proper amount of tension in the belt to ensure synchronous drive. Incorrect tension, whether too loose or too tight, can lead to severe engine failure. Tensioners are available with either manual or automatic adjustment options.

There is no recommended timeframe in which to replace your tensioner, especially as the belt itself usually needs replacing before the tensioner does. However, you should inspect your tensioner each time you service your car to monitor its condition and replace it if necessary.

Standard tensioners typically operate at a maximum pressure of 1500 bar.

Our standard tensioners are specifically designed to fit most commonly used ANSI B 16.5, 16.47, and API flanges.

Standard tensioners are ideal for a wide range of applications. However, for situations with limited space or exceptionally high load requirements, custom-built tensioners might be necessary.

Standard tensioners are well-suited for various bolting projects involving standard flange sizes in industries like: Oil & Gas, Chemical Processing, Power Generation, Shipbuilding, General Construction.

While standard tensioners offer a good range of compatibility, they might not fit every unique flange configuration. An adaptor set (optional) might provide some versatility, but for highly customized needs, custom-built tensioners are the best option.

A tensioner is a device that applies a force to create or maintain tension. The force may be applied parallel to, as in the case of a hydraulic bolt tensioner, or perpendicular to, as in the case of a spring-loaded bicycle chain tensioner, the tension it creates.

Here's how it works: Spring Force: The spring mechanism in the tensioner generates a consistent force. This force is applied to the tensioner arm, which in turn presses the pulley against the belt. The tensioner arm is designed to move, allowing the pulley to adjust its position and maintain the desired tension.

On circular flanges, the recommended use is of at least four Hydraulic Stud Tensioners and, preferably, 25% or 50% cover. For example, on a flange with 36 studs, use four, nine (25% cover), or eighteen (50% cover) Hydraulic Stud Tensioners. For accuracy and speed, some applications require 100% “cover”.
