Take the stress out of onsite services.

Onsite (field) machining includes doing repairs at the breakdown site. The company providing this service utilizes a set of portable machines on the site to repair the area with problems. This eradicates the need of transporting the piece of machinery to a shop where it would be repaired or replaced. 

Onsite machining provides an array of benefits over traditional practices. Moreover, it can be used at any job site or industrial plant. For instance, offshore drilling sites, marine locations, power plants, water utility plants, manufacturing factories, oil & gas industries, and coal mining industries. 

These services are also a perfect solution for new construction projects. Talking about the portable machines, they can be clamped or bolted directly on the job site. They can be easily positioned and mounted in any position. These machines can perform a slew of onsite actions such as: 

  1. Torquing 

Torquing is the art of fastening the tighteners to a perfect extent. For average users, tightening nuts and bolts might not seem important at all. However, in job sites, incorrect torquing can lead to hazardous consequences that can damage the entire machine, structure, or component you’ve built. Torquing can be done in several ways including processes such as rundown, alignment, clamping range, and post-yield zone. The torquing capabilities can also be improved with the help of perfectly calibrated wrenches and analyzing specifications such as fastener material, the environment of operation, bearing surface material, and strength of the joint. Onsite machining services use high-end torque analyzers and run several variations in simulation to achieve the most desirable results. They also conduct periodic checks to make sure that the job site is safe from any kind of torquing errors. 


  • Tensioning 

Tensioning is a process used to achieve preload by direct axial stretching of the bolt. With this process, the inaccuracies created due to friction are eliminated completely. Moreover, it also eradicates the need for a massive mechanical effort that’s required to create torque by adopting hydraulic pressure. Due to this, you can apply a uniform load and tension multiple studs simultaneously. To perform tensioning, you need to have access to longer bolts and an area for seating on the assembly across the nut. It can be performed using both hydraulic nuts and detachable bolt tensioners. The mathematical formula for calculating the preload is Preload=applied load - load losses. Talking about the load loss, it’s the loss of bolt elongation that depends on factors such as the radial expansion of the nut, thread deflections, and embedding of the nut. Onsite services use a high-pressure hose assembly to tighten multiple joints simultaneously. 

  • Pipe Beveling 

In pipe beveling, an angle is formed between the plane perpendicular surface and the edge of the end of a tube or pipe. General, the standard beveling angle of a pipe for welding is 37.5 degrees. There are also other special forms such as J-Bevels that are produced on the pipe ends with the help of automatic pipe beveling machines. Pipe beveling is commonly done to prepare the ends of welding. However, it can also be performed to deburr the cutting ends for safety reasons. Onsite services automate the process of pipe beveling because it saves time and eliminates the need for dirty operations such as torching and hand-grinding. 

  • Cold Cutting 

Cold cutting is a process used to cut a pipe without using heat from a torch (known as hot cutting) with the help of an open flame. There are several advanced cold cutting machines designed to reduce the hazards of thermal cutting. The development of these machines is a reflection of priorities such as safety, time, and money. Cold cutting also helps in the prevention of HAZ (heat affected zone) and prevents the changing of the molecular structure of the metal. It also eliminates the need to grind for creating a suitable welding ready surface. 

  • Flange Facing 

Flange facing is also an onsite service conducted on flange surfaces. This includes timely repair and maintenance of flanges to avoid corrosion and leakages. With this service, you can ensure that your old flanges can maintain the integrity of joints. As flanges continuously experience wear and tear due to turbulent flow and impact of other components during cuts, installation, and construction, they must be maintained to safeguard the integrity of your structure or machine. With flange facing, the flanges are cut to get a spiral groove finish. This allows them to be less liable to any leakages because liquids and gases travel in the spiral path instead of accessing the flange face directly.

Bottom line

On-site machining services simplify your project requirements and makes your work faster. Moreover, you can easily use onsite machining services for any job site.

Hydraulic Bolt Tensioner: How It Works

Image
  For simpler and more accurate tightening of large-diameter stud and bolt assemblies, hydraulic bolt tensioners are mechanical fasteners that are utilized in place of normal bolts or hex nuts. Several bolt tensioners use manual or hydraulic techniques to apply torque. Devices that use hydraulics employ fluid force. Products that require manual power are turned using a hand tool such as a torque wrench . There are also hydraulic bolt tensioners that impart torque using different non-manual, non-hydraulic techniques. The greatest amount of rotating force that can be generated for all varieties of bolt tensioners is indicated by the torque rating. Thrust collar inner diameter and threaded diameter are additional crucial characteristics. To discover more about how hydraulic bolt tensioners operate, read the entire article. How does it work?  Large diameter bolts can be accurately and quickly tightened to high preloads using a hydraulic bolt tensioner . Like hydraulic torque wren...

Guide On Controlled Bolting Services

  Guide On Controlled Bolting Services Torque controlled bolting is a critical element of your operations, and rushing through the procedure may result in a less secure final product than your work commitments. Correctly using the appropriate equipment can boost efficiency and safety on the worksite, allowing your crew to achieve tighter deadlines than you ever imagined possible. In this article, we will talk about controlled bolting services . What is Controlled Bolting? Controlled bolting is the technique of applying a known load to a mechanical joint in order to assure joint integrity. As bolted joints are usually one of the most prevalent components in industrial engineering, the dependability of each joint is critical.  The physics that explains fastening bolting mechanisms are well understood, and we've developed accurate methods of detecting and delivering force to joints regularly throughout the years. Bolted joints are used in a wide range of sectors, from pressure...

All about Flange Facing and Its Advantages

Image
  When there is a pipeline or pipework, you will see flanges or welded joints made up of distinctive designs, sizes, and materials. A flange can be described as an internal or external ridge or a lip/rim that is carried out for strength. There can be an iron beam in the form of a T-beam or I-beam. There can also be a flange of an attachment to a different object such as a steam cylinder or on the ends of a pipeline etc. There is a lot of evidence that shows that in various pipeline systems, both flanges and valves can release hydrocarbons, and the piping ends up becoming the biggest contributor. Hence, a good flange-facing process and regular inspection can be a great solution to this problem.  Importance of Flange Protection When discussing the utility, oil, and gas industry, thread protection and pipe flange are two of the most important things. There is an issue of contamination when we talk about these industries. This contamination not only happens after or during the sto...
