  Reduce bolting job time with a Hydraulic torque wrench Introduction   T he world is full of tools that we use for various applications. When it comes to the tightening and loosening of bolts and nuts, a torque wrench is the most preferred tool. The tool can be used in almost every bolting application and still deliver accurate and consistent torque output. However, when we talk about major industries like oil & gas, power, wind, steel, cement, and mining industry that can complete bolting jobs faster and deliver lower downtime. To meet such industry requirements, the hydraulic torque wrenches delivers the best power to weight ratio. 1. Knowin g The basics   Let us recap what is Torque and a wrench to understand torque wrenches better. Torque Torque is the measurement of force applied on an object which causes it to rotate. Wrench Wrench is a tool used to provide torque to turn objects. The most common shapes are open-end wrench and box-end...

  Bolt tensioners for leak proof joints Introduction   Leakages in Bolted flange joints have always been a problem. To resolve such painful issues, precision bolting tools like bolt tensioners and torque wrenches are used to achieved joint integrity between flanges. In this article, we will understand how a bolt or stud tensioner achieves joint integrity and prevents flange leakages. 1. Need for Bolt Tensioning   A bolt or stud tensioner stretches the bolt axially to achieve the required preload. This replaces a high mechanical effort delivered to achieve the desired torque with hydraulic pressure that requires significantly less effort. Also, a uniform load can be applied on multiple bolts simultaneously to achieve equal tensioning. Therefore, the preload is equal to applied torque minus frictional losses. Bolt Tensioning requires a longer bolt length and enough seating space on the assembly around the nut. A minimum length equal to 1-1.5 times the diameter of...

Essential Bolting Tools Introduction   The necessity of using right bolting tool for right fit is very essential to prevent the bolted joints from loosening, from leakages and thus prevents from major hazardous accidents. Let us first understand some of the key bolting concepts before identifying the essential bolting tools for bolt tightening. 1. What is Bolted Joint? Bolted joint, is one of the oldest and most common type of joint in many industries like construction, machinery equipment and piping industry. The joint consists of fasteners that holds two or more parts securely. Bolted joints come under the category of temporary joints which means the joint is not permanent. Few industries prefer bolted joints over permanent joints with a benefit of mainly easy serviceability and weight requirements. 2. Why Joints fails? For bolted joints, appropriate bolt tightening techniques and right bolting tools are crucial for the safe operation of many types of equipment. However, if...

  Pipe Cutting and Bevelling in an efficient way Introduction   We see a lot of piping in plants like Oil & Gas, Hydro Power, chemical industries for generating power or for transmitting fluid or offshore rig in oil and gas. Onsite services like Pipe cutting and Pipe beveling play an important role in piping industry to make a continuous long pipe, to install valves between pipes, to install pressure gauges and other safety and measuring instruments, and during repair and maintenance work for operating efficiently and safely.   1. What is Pipe Cutting Pipe cutting or pipe profiling are one of the onsite services that cut pipes to create a desired profile. Typical profiles include straight cuts and mitre cuts. Factors involved in choosing a method or technology for cutting pipes are The material The wall thicknesses squareness of ends and requirements of end conditioning.   2. What is pipe B eveling? When welding two pipes together, the ends...
