Tube bursting bench

Main functions

This bench is equipped with a static pressure generator, specially developed for high expansion tube testing.
The pressure generator makes it possible to apply a progressive pressure build-up, as well as pressure levels, with controlled pressure (even in the event of creep under pressure of the product tested).

This very gradual and regular rise in pressure allows detect very precisely the maximum burst pressure or hernia formation on the tube under test.
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.

Operating mode

The tube under test is connected to quick-connect tooling; These tools are mounted on mobile trolleys to adapt to the length of the tube;
The system applies static pressure according to a programmable cycle, with gradual pressure build-up ramps and adjustable stages;
The test zone is fitted with a transparent cover featuring a safety switch that automatically cuts off the pressure when the cover is opened;

Features

The test bench consists of 6 parts:

• The self-supporting stainless steel chassis on castors
• The test area, including the connections for the products to be tested and a recovery sink
• A transparent cover with closure detection system
• The hydraulic circuit including the pressurization system
• The electrical cabinet
• Mobile control panel including screen, keyboard and mouse
