5 warning signs of pressure tank failure

In this article, we will learn about the dangers of pressure tanks, signs of pressure tank failure, and ways to prevent costly failures.

According to Sefir Arjan's commercial report, pressure vessels are critical and critical equipment in many industries, and any failure in their performance can cause serious financial losses and safety risks. Corrosion, cracking, reduction of body thickness and failure of control equipment are among the factors that threaten the health of these tanks. For this reason, the importance of inspecting pressure vessels in identifying problems before an accident occurs is very high. In this article, we learn about the dangers of pressure tanks, signs of pressure tank failure, and methods of preventing costly failures.

Why can pressure vessels become dangerous?

What is a pressure tank? It is a tank that is designed to store fluids such as gases or liquids under a pressure higher than the ambient pressure. Due to high energy storage due to internal pressure, these equipments can cause serious risks in case of technical failure or reduction of body resistance.

The risks of pressure vessels increase when factors such as corrosion, structural cracks, overpressure or failure of safety equipment are neglected. Damage to the tank body can cause leaks, equipment failure, or even sudden release of stored energy.

For this reason, the failure of pressure vessels is not only a simple technical problem and can cause the production process to stop, damage to the surrounding equipment and pose a risk to employees. Controlling the condition of the body, checking the safety equipment and performing periodical inspections are the most important measures to reduce these risks.

What are the most important causes of failure of pressure vessels?

The failure of pressure vessels is not caused by a single factor, but is the result of the accumulation of problems such as corrosion, structural damage, overpressure and improper maintenance. Identifying these factors in the early stages plays an important role in increasing the safety of pressure vessels and preventing possible accidents.

Corrosion is one of the most common causes of damage to pressure vessels. Continuous contact of the tank body with corrosive substances or inappropriate environmental conditions can reduce the thickness of the wall and create weak points in the tank structure. Reducing the thickness of the body reduces the resistance of the tank against the working pressure and increases the probability of failure.

Creating cracks in the body or connections of the tank can be one of the most important signs of failure of the pressure tank. These cracks may be caused by repeated pressures, metal fatigue, poor welding quality, or poor working conditions, and may spread if neglected.

Each pressure vessel is designed to withstand a certain amount of pressure. Increasing the pressure more than the allowed range puts pressure on the tank wall and control equipment. Failure of safety valves or improper operation of pressure control equipment can increase the possibility of damage to the tank.

Improper maintenance and delay in inspection

Failure to perform periodical services and delay in checking the status of the tank will cause small problems to become serious failures. Testing pressure vessels and regularly checking the condition of the body, thickness measurement and safety equipment helps to identify defects early and avoid heavy costs.

Signs that the pressure tank needs to be checked

Timely identification of abnormal symptoms in pressure vessels is one of the most important measures to prevent serious breakdowns and increase equipment safety. Many tank problems can be detected at an early stage, and a pressure tank inspection can help identify these problems before they become a serious hazard.

Any deformation, bulge or swelling in the body of the tank can be a sign of abnormal pressure or damage to its metal structure. These changes indicate a decrease in body resistance and should be checked by an expert before proceeding.

A sudden drop in working pressure or seeing a leak from the body, fittings or tank valves can be a sign of a problem in the system. Continuation of the tank operation in such conditions may aggravate the damage and increase the safety risks.

Visible rust and corrosion

Observing signs of rust, peeling of the metal surface or corrosion in different parts of the tank is one of the most important things that requires expert investigation. Corrosion can reduce the thickness of the tank wall and reduce the pressure bearing capacity.

Abnormal noises such as knocks, vibrations or unusual changes during tank operation may indicate a problem with the equipment's performance or working conditions. Checking these symptoms in the early stages can prevent extensive damage.

Safety valves, pressure control equipment and other safety components play an important role in preventing accidents. Improper operation of this equipment can increase the risk of failure and makes the need for periodic inspection of the tank more serious.

What are the consequences of neglecting the failure of the pressure tank?

Ignoring the early signs of failure of pressure vessels can cause serious problems for equipment and industrial processes over time. Among the most important consequences of neglecting the condition of the reservoir, the following can be mentioned:

Stopping the production line and increasing costs

A sudden failure of a pressure vessel may cause stoppage of related equipment and disruption of the production process. The cost of emergency repairs, replacement of parts and stoppage of industrial activity is much higher than preventive costs and regular maintenance programs of pressure vessels.

Damage to equipment and increased risk to employees

Due to the stored energy inside, pressure vessels can pose serious risks to surrounding equipment and personnel if they fail. Compliance with the pressure vessel standard and periodic inspection of the condition of the equipment play an important role in reducing the risks of pressure vessels.

How to prevent failure of pressure vessels?

Prevention of failure of pressure vessels requires a combination of proper maintenance, control of working conditions and specialized inspections. Adherence to preventive programs allows problems such as corrosion, cracks or loss of performance of equipment to be identified in the early stages.

One of the most important preventive measures is regular inspection of pressure vessels and destructive and non-destructive tests. These inspections help identify problems such as corrosion, cracks, body thickness reduction, and peripheral equipment defects.

Each tank is designed for specific pressure, temperature and working conditions. Using the tank outside the specified range can increase the pressure on the body and reduce its useful life.

Inspection of safety valves and accessories

Safety valves and control equipment play an important role in preventing unauthorized pressure increases. The proper functioning of these parts must be checked regularly to avoid dangerous conditions.

Recording information about the repairs, tests and inspections done helps to better manage the condition of the tank. These records allow for more accurate planning of pressure vessel maintenance and decisions about when to repair or replace equipment.
