Calibration Cover Image

Calibrating torque wrenches and pressure gauges of hydraulic power packs improve the accuracy of the amount of torque applied on a given fastener. Calibration ensures that the torqueing tool has applied the right amount of force to fasten a bolt accurately. Similarly, calibrating hydraulic the pressure gauges of hydraulic power packs to ensure that the pump is providing the required pressure to the torqueing or bolt tensioning tool. As tools and pumps age, it may over tighten or loosen fasteners, that can cause the bolt to deform or break. Therefore, Calibration helps maintain the accuracy and consistency of the tool and pump.


Why Calibrate?

  • To ensure that the tool is making persistent measurements.
  • To ensure the quality of the torque wrench and hydraulic power pack has not deteriorated and still maintains accuracy.
  • Ensure peak performance of the bolting tool and bolt tensioning tool pump, when operational.
  • To test a new product.
  • Ensure employee and plant safety.
  • To maintain industry and government standards.


When to Calibrate your Torqueing Tool, Pressure Gauge? And How often?

  • Abide with the manufacturer’s recommendation of calibration to understand the frequency of calibration required.
  • Calibrate before starting any large scale projects/ new jobs which require heavy usage of your torqueing tools.
  • Calibrate your tools after repairs or replacement of spares.
  • To meet certification standards.
  • Carry out a scheduled calibration frequently if tool and pump dependency is too high.
  • It is recommended that at least calibrate annually for safe operation.

Pipe Cutting machining

What is Pipe Cutting and Beveling?

As the name suggests, pipe cutting is an onsite machining process that cuts pipe to ensure it is ready for welding to be connected with a new pipe. It also helps service a corroding pipe. We use cold cutting techniques to ensure work can be carried out in a flame-proof setting during plant maintenance or shutdown.

Considered to be a finishing job, beveling is the process that helps the pipe to be ergonomically positioned to be connected with a new pipe. It changes the sharp-cut open edges to a smoother edge for safer handling.


Why Use Automated Pipe Cutting/ Beveling Tools?

In comparison to traditional tools;

  • Using automated pipe cutting and beveling tools saves time and provides more accurate results consistently.
  • It avoids the human error caused ergonomic issues
  • It is safer to operate and requires less manpower
  • Cuts and Bevels materials that cannot be torched to ensure fire safety


Where Are They Used?

  • Pipe – severing and squaring
  • Flange re-surfacing
  • Desalination plant pipe severing & beveling
  • Counterbore machining
  • Food processing plant pipe severing & beveling

Bolting in Railways system

Bolts are the backbone to the railway industry. They need to be durable enough to withstand various factors to maintain joint integrity. An ideal bolt needs to be capable of

  • Absorbing shocks and vibrations
  • Giving protection to the passenger against different forces
  • Should be non-corrosive
  • Should be easy to derail and change with specific tools
  • Should possess high torque resistance

Majorly used in holding the joint between the two ends of the tracks to maintain the balance between them, read the full list of applications here. Any track bolts not tightened correctly can lead to derailing.

While we understand the importance of bolts and its application in railways, it is also crucial to know about how to torque them with precision using the right type of torque wrenches. In Railways, the joints of components will constantly experience fast movement and high speeds. Incorrect bolting methods and uneven bolt load will lead to heavy vibration and misalignment of joints. Hence it is critical that the torquing technology used provides high precision bolt load with optimum accuracy and consistency.

The latest in torqueing technology is the Battery or Cordless torque tools. These tools provide greater accuracy with less manpower and time in comparison to manual torquing methods. Other significant benefits include:


  • Recording of bogey related data such as bogey no, the torque applied, no of bolts torqued, etc.
  • Can be used for smaller bolts in coach factories or for track maintenance
  • Provides accurate readings with digital display
  • Provides alerts when torque is achieved, thus avoiding human error
  • Faster operation through run down and torquing dual speed mode

These tools can also be upgraded to reaction-arm free bolting with the HYTORC WASHER– the safest method in next-gen bolting.

torque wrench working

Hand safety is a major concern in industrial bolting operations, especially when using outdated tools and methods that inherently create hazardous pinch points. One injury may result in heavy personal injury losses and facility shutdown (for hand injury investigations) with overburdening financial costs running into millions. The HYTORC Washer is the only fastener in bolting systems that reduces the risks of hand injury by completely eliminating pinch points when using torque wrenches.


The HYTORC Reaction Washer is a fastener that features a smooth side to reduce the friction of the turning nut, a knurled side to keep the Washer from rotating, and outer lobes to brace reaction forces, thus eliminating the need for reaction, and completely eliminating dangerous pinch points. The HYTORC Backup Washer features knurls on both sides to keep the backup-nut from rotating, thus eliminating the need for a backup wrench and completely eliminating the danger.

  • VCI 2016 (Verband der ChemischenIndustriee.V.)
  • VDI 2200 (2007)


Specification for ASME Hardened Washer

ASME PCC-1-2013 – Appendix M – M-1.1 Usage (page 71):

The use of washers on pressure boundary bolted flange joints is optional. However, it is generally recognized that the use of through-hardened steel washers will improve the translation of torque input into bolt preload by providing a smooth and low friction bearing surface for the nut.

Washers protect the contact surface of the flange from damage caused by a turning nut. These are important considerations when torquing methods (either manual or hydraulic) are used for bolt tightening.
