Customer
Our client is a leading European supplier of oil, gas and pipeline coatings for various on- and off-shore applications.
Tested product
Pipeline tubes
Pipeline pipes are large diameter pipes used for the long-distance transport of certain fluids, such as fuels (oil, fuel oil, etc.) or natural gas. They are often equipped with plastic coatings, which provide mechanical protection and thermal insulation, among other things.
Objective
Testing the pull-out strength of protective coatings on pipeline pipes. The coatings must meet the requirements of various standards, including ISO 21809 (Petroleum and natural gas industries -- External coatings for buried and immersed pipelines used in pipeline transportation systems) and NF EN 12068 (Cathodic protection - External organic coatings for corrosion protection of buried or immersed steel pipes in conjunction with cathodic protection)
Problematic issues
The peeling bench must be autonomous and easily transportable in order to carry out the tests directly on site.
Solution and result
LF Technologies' teams of engineers and technicians have designed a special peeling machine to evaluate the pull-out strength of pipeline pipes. The bench can operate autonomously thanks to its battery operation, and can be easily moved thanks to its transport case.
The machine is equipped with a clamp that grips the end of the sample to be tested. This clamp is inserted into a Ø 150 mm reel. The machine's drive wheels, combined with a light barrier, are used to hold the torn-off part of the sample in a radial position, without a return roller. Two removable side pulleys allow the machine to be strapped onto the tube if required.
A 4-button keypad is used to tighten and loosen the clamp, control the rotation of the drum, as well as the movement of the machine and the cycle. No tools are required thanks to the automatic clamping system for vices, jaws or clamps. The display, placed above, indicates the measured value of the tearing force in relation to the length of the tearing.
The programming, analysis and output of the results, via a report ticket, is included in the transport case. Data exchange between the machine and the case is carried out using a wireless link (Wi-Fi).
The peel tester's autonomy allows it to be adapted to other uses, such as testing the resistance to tearing of conveyor drum linings or on marine sites.
