In leak repair, choosing the correct fastening tool can achieve twice the result with half the effort. Hydraulic torque tools not only reduce the burden on the operator but also ensure the quality of fastening while saving time.

Choose the right repair tool

Oil and gas, oil refining, petrochemical, chemical and other industries, pressure vessels, heat pipe joints, valves, pumps, etc., often face the problem of bolt fastening. In order to achieve effective sealing, it is necessary to ensure that the flange gap is even, the sealing surface is installed tightly, the connection point is leak-free, the use of suitable media, the gasket is in good condition, etc. Therefore, receiving professional training, fully mastering the knowledge of bolt fastening, selecting appropriate fastening materials and tools, and using hydraulic torque wrenches safely and compliantly can save time, effort, and complete leak repair tasks accurately and efficiently.

Among them, choosing the correct maintenance tools can not only improve work efficiency but also greatly improve the level of leakage repair and prevent leakage from happening again. Pneumatic and electric torque wrenches rely on a gear system (torque multiplier system) and are therefore more prone to becoming inaccurate or out of calibration than hydraulic torque wrenches. For pneumatic torque wrenches, torque accuracy and speed of use can also be affected by the availability of a suitable air source (pressure and volume). Likewise, battery power can affect the torque accuracy and speed of use of a battery-powered tool.

Applications of hydraulic tools

Hydraulic tools are widely used in various heavy industries such as:

– Mineral mining

– Oil and gas, refining, petrochemical, chemical

– power generation

– Agricultural production equipment

– railway system

In addition to choosing the right tool, two key materials are required to properly perform a repair job — the correct torque and a high-quality calibrated tool.

The effect of using hydraulic tools

1 Speed

Manually tightening each component with large and heavy tools is time-consuming, small and lightweight hydraulic torque tools allow the operator to quickly move the tool into position, apply the set torque with ease, and get the job done.

2 Security

Using heavy hand tools can cause physical fatigue to the operator and even possible personal injury during use. Lightweight hydraulic tools not only minimize the risk of personal injury but are also more mobile. The compact design reduces the risk of pinch injuries, and the swivel joints that connect the hydraulic hoses provide greater flexibility for hose routing. Hydraulic systems can apply greater force with less physical exertion from the operator than hand tools.

3 Dimensions, weight, and accessibility

Compact design and lightweight materials make hydraulic tools the ideal solution for manual repairs of fastened components. In oil refining, petrochemical, and chemical companies, there are some unreachable components, or there are points on the components that are difficult to maintain, which creates many difficulties for maintenance. The low-clearance wrench provides more possibilities for operators to repair in spaces with relatively small clearances.

4 Precise

Properly calibrated hydraulic torque tools are ≤±3% accurate, ensuring high repeatability and applying the desired torque every time.

Which hydraulic tools to choose

1 Hydraulic torque wrench

TorcStark hydraulic torque wrench is a new generation of high-tech products. It is light in weight and high in strength, and its compact body can perfectly complete the pre-tightening and loosening of bolts. It is the first choice for skilled workers, maintenance personnel, and mechanical workers to complete their work efficiently.

2 Hydraulic bolt tensioners

TorcStark hydraulic bolt tensioner is specially used in oil refining, petrochemical, chemical, pharmaceutical, and other industries. It can be widely adapted to various working conditions of enterprises and meet the needs of flange maintenance and fastening.

3 Intelligent hydraulic control unit

Compared with similar products currently on the market, the intelligent hydraulic control unit has the following advantages:

Explosion-proof design;
Good afterburner repeatability;
The control accuracy is higher, and the afterburner uncertainty is controlled within ±1%;
The process is traceable.

On the premise of ensuring safety and compliance, the fastening efficiency of flange bolts is greatly improved. The entire system is connected wirelessly, enabling the automatic recording of data and images during operation.
