Valve testing machine

What is Valve?

Valve is an application that controls the flow of the fluid or gas. It manages direction or controls the flow of a fluid or gas by opening and closing of various passageways.

Valves play a vital role in most of the industries involving pipelines or other applications. Some of the common industries having valves are oil, gas, petrochemicals, marine industry, and many more.

There are 6 different types of valves namely globe, gate, ball, butterfly, check, and plug. Every valve is differently designed based on the characteristics of the application and also the pressure. Therefore, different industries use different valves.

Why is Valve Testing important?

As valves are a crucial application in many industries, it is important that the valves function accurately i.e. directing the right pressure without leakages. There have been cases that these high pressure systems have exploded due to leakages or inaccurate pressure transfer. Thus, it is important to ensure that joint-integrity is maintained in such a high pressure system for safety and productivity.

Valve testing is conducted as a maintenance process to evaluate the condition or health of an operational valve. Following are the functions of a valve testing machine on a high pressure system:

  • Testing for any valve leakages
  • Seat and seal test
  • Seat leakage inspection
  • Suitability for fluid & Gas testing

Valve testing is generally conducted to rectify issues like mechanical friction, flashing, cavitation, choked flow, erosion, and noise in valve to name a few.

The benefits of these valve testing machines are that all the tests are automated that allows them to create a log of all past data. Additional features like rotating test benches, vacuum testing, customizable equipment based on requirements are also provided.

Why does a valve corrode or deter?

As valves are constantly being exposed to gases and liquids there is a high probability of the system to start corroding. Other common problems that occur are that minerals get accumulated to create leakages.

How frequently is valve testing required?

Depending on the pressure faced by the valve, testing should be ideally conducted anywhere from every two months to three years based on the application and the pressure it works on.

What does ABS offer?

Being an industry leader for more than two decades, we have developed our brand as a one stop solution center for all industrial requirements. Our valve testing machines can test high pressure systems to seamlessly expand and evolve with your business.

Our tools offer the lowest total cost of ownership (TCO) and the highest return on investment (ROI) within the average life of our testing machine. The systems are designed to be more accurate and precise than other comparable products.

Our high pressure valve testing systems offer users the ability to simultaneously test multiple valves with one system. All these products include test barriers and hydraulic seal clamps. Also, to offer assurance of the highest standards, all brands offered by ABS are CE certified and manufactured in an ISO 9001 certified factory.

Effects of side load in torque wrench breakdown

As defined in our previous article about different types of torque wrenches, a torque wrench applies the required amount of torque on a fastener i.e. a nut to either tighten or loosen it. However, there are many factors involved that deteriorate the life of these fastening tools. Based on experience in the industry, we have collated a list of common problems leading to tool failure or breakdown. Also, we will be sharing some preventive measures that can reduce maintenance costs.

Today’s cordless tools will convey massive amounts of power and execution in a more compact package and can even outperform their corded predecessors. The run-times are getting longer and the charge times are getting shorter. One of the most important chapters in the history of torque tools was the introduction of lithium-ion technology to the industrial bolting industry. This introduction created a fundamental shift in torque tool technology that continues to have an impact on industrial work environments.

torque wrench

Before we start talking about different types of torque wrenches, it is important to know what a torque wrench is. A torque wrench helps apply the required amount of torque on a fastener such as a nut or a bolt to either tighten or loosen it. When applying the high value of torque, these wrenches would require a reaction arm that would lock itself at an adjacent point (As Newton’s 3rd law states, every action requires an equal and opposite reaction).

When it comes to bolted joints, utmost importance is given to joint reliability in applications such as pressure vessels & pipe flanges in oil & gas for leakage free joints; in automotive/machinery for guarding against vibration. When it comes to infrastructural joints of long-term nature such as bridges and towers, the Fit-it-Forget-approach is commonly seen.

Joint reliability is determined by various factors, bolt load accuracy playing a predominantly critical role among these. To control the impact of external factors such as vibration and temperature on bolt load, we need to understand the concept of Controlled Bolting Mechanism which is a scientific method of bolting.
