How to Pressure Testing Industrial Hoses

Industrial hoses are a crucial component in various industries ranging from oil and gas, chemical, manufacturing, and mining, to name a few. These hoses are designed to transfer liquids, gases, chemicals, and other materials from one point to another. With their frequent use, industrial hoses are prone to wear and tear, which could result in leakages or even breakages. Therefore, it’s important to carry out pressure testing regularly to ensure they’re functioning correctly.

This article provides an overview of how you can pressure testing industrial hoses, and the benefits of doing so.

Understanding Pressure Testing

Pressure testing is a process of verifying if a hose can hold its design pressure. The design pressure is the maximum pressure that the hose can withstand before rupturing or failing. Pressure testing is typically done before commissioning a hose or whenever a hose has undergone maintenance or repair. There are two types of pressure tests: hydrostatic pressure tests and pneumatic pressure tests.

What is a Hydrostatic Pressure Test?

A hydrostatic pressure test involves filling the hose with water and pressurizing it to the desired level using a pump. The hose is kept at the maximum pressure for a specific time, usually between five and 30 minutes, while inspecting it for any signs of leaks, bulges, or deformations. If the hose passes the hydrostatic test, it means the hose is safe to use without any significant risk of failure.

What is a Pneumatic Pressure Test?

A pneumatic pressure test is similar to a hydrostatic pressure test, except that instead of water, the hose is filled with air or nitrogen gas. The desired pressure level is achieved using a compressor, and the hose is kept at that level for a specific time, usually between five and 30 minutes. Like hydrostatic pressure testing, if no significant leaks, bulges, or deformations are observed during the test, the hose is safe for use.

Why You Should Pressure Test Your Industrial Hoses

There are several benefits of pressure testing your industrial hoses, including:

1. Ensuring Safety: Pressure testing helps to ensure the safety of the workers and the environment. A failure in an industrial hose could result in hazardous situations, leading to severe injuries and significant financial losses.

2. Identifying Damage: Regular pressure testing allows you to identify any damages early, preventing costly failures or downtime. Signs of damage such as leaks or bulges indicate that the hose is damaged, and it needs to be repaired or replaced.

3. Maintaining Quality: Pressure testing ensures that industrial hoses maintain their quality and functionality, reducing the risk of failure, and increasing the product lifespan.

4. Compliance: Pressure testing is a requirement in various industries. By pressure testing your industrial hoses, you ensure that you comply with the regulations, avoiding any legal or financial penalties.

5. Save Time and Money: Regular pressure testing can save you both time and money in the long run. Early identification of damages means you can repair or replace the hoses before catastrophic failure, therefore reducing downtime and the cost of repairs.


In conclusion, pressure testing is a crucial process in ensuring the safe and efficient operation of industrial hoses. Performing regular pressure testing can help identify any damages early, ensuring the continued quality and functionality of the hoses, and avoiding costly failures, downtime, and injuries. Remember to include pressure testing as part of your regular maintenance plan.
