As one might know, using manual torque wrenches to complete bolting jobs is tedious, inaccurate, time consuming, and unsafe. Hence, major industries like power, heavy manufacturers, oil and gas, and infrastructure use hydraulic, battery or pneumatic torque wrenches to achieve precision bolting. In this article, we will talk about some manual bolting methods practiced and draw a comparison between hydraulic, battery/ electrical pneumatic torque wrenches.

The most common reasons for heavy industrial applications to use battery, pneumatic or hydraulic tools is because of the high torque requirement to open old, corroded and rusty fasteners which is labour intensive and time consuming if done manually. Another reason to opt for these torque tools is that there is no operator fatigue involved.

One of the most powerful and widely used tool in the industry, hydraulic torque wrenches are used in multiple industries. It is not only the ideal tool to reduce job time but also helps complete bolting jobs in confined spaces.The benefits don’t end there, multiple bolting accessories allow hydraulic torque wrench to be the most customizable tool while delivering the highest rate of accuracy and power in comparison to any other torque wrench. In this article, we will discuss about the key benefits and fundamentals of hydraulic torque wrenches and their accessories like reaction arms and links.

Workplace accidents not only lead to devastating injuries to workers but also costly fines, shutdown, and equipment damage impacting the finances and productivity of the plant. In this article, we will provide a checklist to ensure safe bolting services are practiced everywhere.
First things first, every employee handling torque wrenches should be trained to operate the tool safely. Hydraulic torque wrenches being one of the most injury-prone tools needs to be handled appropriately to avoid broken hands or fingers. An untrained operator can damage his eyes and exposed parts of the skin from the toxic oil of the hydraulic torque wrenches.

As flanges carry or transfer both flammable and non-flammable liquids and gases for major industries like oil and gas, petrochemicals, subsea, ports, etc. they always need to be checked for leakages and must maintain joint-integrity.To ensure safety, after every bolting and machining job during maintenance, the flange is pressure tested at high pressures to ensure the accuracy of the job. In this article, we will provide a step by step guide on what factors need to be considered to ensure accurate bolting with torque tools on flanges.

Bolt Tensioner design

A bolt tensioner is an annular jack that fits over the fastener to be tightened. Followed by the definition and components mentioned in the previous article on components involved in bolt tensioners, we will provide you an insight into the design of the tool that will also explain how do bolt tensioners operate. We will also be talking about applied and residual load. We highly recommend you to read information about the components from our previous article to understand the operation better.

As mentioned in our previous article, torque wrenches apply the desired torque on a fastener to either loosen or tighten it. However, there are a lot of factors involved that reduce the life of these torque tools. Based on our two decades of experience in the industry, we have compiled a list of common problems that cause the tool to fail or breakdown. To slow down the deterioration, we will share some preventive measures that can reduce maintenance costs.

Types of torque wrenches

 

It is important to know what a torque wrench is before we discuss the types of torque wrenches available in the industry. A torque wrench is used to either tighten or loosen a fastener (bolt or nut) by applying the right amount of torque on it. As Newton’s 3rd law states, every action requires an equal and opposite reaction, applying the high value of torque, the wrenches would require a reaction arm to lock itself at an adjacent point.
