Just like other cardboard products, core pipes play a significant role in the construction industry. These pipes find application in multifarious construction projects. This is because these tubes not only support structure but also help in pouring concrete vitally.
What are Core Pipes?
A core pipe is a cardboard tube or core tube, cylindrical in shape and used for several construction applications. The most popular among these applications is reinforcing concrete. Builders make use of these pipes in different forms in the columns, footing, and piers. At the time of pouring concrete, core tubes play a significant role. They hold the material in the desired form till the time it is dried and hard. This helps in building solid, robust, and uniform structures.
Besides, core pipes are also used to drill boreholes at the time of soil sampling, examination, and collection. This is because core pipes are hollow cylindrical tubes that allow easy and effective extraction of samples of soil. As a result, the soil is extracted and the surroundings remain undamaged.
For any application of the core pipes, it is expected to have the required strength so that the process can take place conveniently and efficiently. It is due to this reason, that manufacturers of core tubes or cardboard tubes test them using a core compression tester.
What is a Core Compression Tester & How Does It Measure the Tensile Strength of a Core Pipe?
A core compression tester is an intelligently designed instrument in the packaging industry which determines the core collapsing strength of cardboard pipes or tubes. With the help of this testing machine and a quadrant scale, core pipe manufacturers determine the capacity of a cardboard pipe and dedicate it to respective applications. A quadrant scale is an instrument that measures the basis weight of the cardboard and helps manufacturers decide if it has the desired weight and thickness to be formed into a cylindrical pipe.
A typical core compression tester developed by UEC has the following features:
Adjustable testing area that can accommodate specimens of various sizes.
Clamping jaws to hold the specimen of any size or shape, strong and in place during the test. The unit comes with core samples of 6”.
A motorized unit, that operates via a piston. It applies a uniform pressure to crush the core pipe specimen and test its core compression test.
A digital load indicator, that records and displays the max. peak crush value of the test.
Its load capacity ranges between 0 and 2000 Kgf or 0 and 5000 Kgf.
At the time of the core compression test, the user puts the sample on the adjustable test area. The clamping jaws hold the sample tight. The unit puts maximum pressure on the sample until it gets crushed. This determines the core pipe sample’s resistance to the force. The application of pressure stops when the sample gets broken. After this process is completed, the maximum peak crush value is recorded and displayed on the digital load indicator.
Conclusion
With the help of high-quality compression testers, deciding the application of a core pie becomes easy. Since core pipes are important in the construction industry, it is important to test these components before putting them to work. Hence, investing in equipment like core compression tester and quadrant scale in addition to otters can significantly help. Contact UEC to make this possible.
