BURST PRESSURE TESTING

The concept of burst pressure testing is based on a rigorous experimental procedure aimed at assessing the maximum resistance of a component, a welded assembly, or a hydraulic system under pressure. This method involves applying an increasing internal pressure, measured in bars, to the test product until it reaches its point of rupture or failure. This process not only determines the resilience limits of the materials but also plays a crucial role in preventing potentially hazardous structural failures.

LF Technologies: Precise, safe burst testing

As a specialist in the field of test benches, LF Technologies is committed to providing advanced solutions for pressure testing. Our burst test benches, equipped with servo-motorized plunger piston technologies, offer unrivaled precision in controlling pressure build-up and a fine detection of burst pressure, while ensuring a high level of safety for users.

Our key test bench for burst pressure testing – CRASH-TUBE

This bench is designed for conducting proof pressure and/or burst tests on flexible hoses. It is capable of testing:

  • Long corrugated tubes, which deform significantly when pressurized.
  • Short smooth tubes, which possess a very high resistance to pressure.

This bench is equipped with a static pressure generator, specially developed by LF Technologies for these testing conditions.
The pressure generator allows for a gradual increase in pressure, as well as pressure holding stages, with controlled pressure (even in the case of creep under pressure of the tested product).

The very gradual and steady pressure increase enables highly precise detection of the maximum burst pressure or the formation of a hernia on the tested tube.
The pressure generator is a motorized syringe. The precision control of this motor allows for fine measurement and regulation of pressure, with a user-configurable pressure rise rate, as well as automatic detection of the rupture point. This technique also ensures intrinsic safety for the user during a burst (as there is virtually no energy storage in the system).

The internal volume of the syringe is sized to cover a wide range of expansion volumes of the tested products. And in case of a greater volume, the machine is equipped with an automatic valve, allowing the pressure in the tube to be maintained while the syringe refills.

The tooling for connecting plastic tubes easily adapts to various diameters and lengths of tubes, without constraining the ends.

Principle and Utility of These Burst test

The process of burst pressure testing is meticulous and highly technical. These procedures aim to subject components, welded assemblies, or hydraulic systems to increasing internal pressure, often well beyond their standard operational capacities, until they reach their point of rupture. This reliable technique evaluates maximum resistance and identifies potential failure points of materials and structures.

Importance of Pressure Resilience Tests

These tests are essential for ensuring the safety and reliability of products under extreme conditions. For instance, in the aerospace sector, these pressure resilience tests confirm the ability of components to withstand extreme pressures during flight. In the automotive industry, they assess the resistance of pressurized parts, such as fuel and oil hoses or lines, to prevent operational pressure failures.

Realistic Simulation of Extreme Conditions and Compliance with Standards

The primary advantage of these test procedures is their ability to simulate the real-world conditions that products will face. This enables manufacturers to anticipate how their products will behave under extreme pressures and identify weaknesses before they become critical. These tests are crucial for ensuring the safety of end-users and for compliance with national and international safety standards.
