Concrete Pipe Testing Machines

The Testmak Concrete Pipe Testing Machines are is used for compressive strength tests of concrete and steel pipes whose from 100 mm up to 3000 mm(outer diameters) pipes. Concrete pipe test machines are produced of capacity of between 400 kN to 1000 kN.
The pipe test machines frames are rigid 2 column constructions with superior axial and lateral stiffness and are precision aligned. The load-controlled double acting piston is integrated to upper beam. The actuator has anti-rotation system to prevent the natural tendency of the actuator to rotate. The stroke of the double acting actuator is 400 mm. Load cell is used for precise load measurement and closed loop control.
The rectangular shaped top bearer is detachable from the actuator and the bottom bearer is V-shaped with an angle of 150°. During pipe loading the system doesn’t permit top bearer to move at horizontal plane and allows it to move at vertical plane of a minimum value of ±8°.
Upper crosshead height adjustment is done with electric motor drive for easy and precise test set up and manual through locking pins are used to fix the upper crosshead. The chassis has a frame fixing system.
Frames have to be anchored to concrete base. Steel fasteners and anchorage plan are sent to the customer before installation. Steel fasteners have to be anchored to concrete base by customer according to plan. Following this anchorage process, the frame is assembled.

Use of the Concrete Pipe Test Machines
Experiments can be performed than on automatic control and data acquisition unit or with the free TCM200 computer software. Tablet and smartphone applications are also available optional. By connecting with smartphone ot tablet the machines via wireless internet (Wifi) and can perform tests, print test reports from the thermal printer. (reporting, graphic output, etc.)
Thanks to its easy use, it allows operators with little experience to do the tests without any trouble.
To start the test, it is sufficient to place the concrete pipe samples centered on the lower loading plate and to perform the following operations after the press is turned on:
• Choosing the sample to be tested.
• Pressing the “Start” button on the control unit.
• The machine starts loading at the set test speed. When the sample is broken, it automatically stops and returns to its initial state.
• Experiment result and test parameters are automatically saved.
LCD Graphics Data Acquisition and Controls System
TCM200 is designed to control the machine and processing data from load cells or pressure transducers installed on the compression machine frame. Easy to read LCD graphics display and button data keypads make the unit quick and straight forward to operate. All interactions with the measuring system are via the front control panel by using simple menu-driven procedures. The TCM200 digital allows real time load us time graph. At the end of the test cycle, the results can be stored in the large memory or downloaded to a PC in TCM200 software format.
The TCM200 control console includes a multi-valve hydraulic pump, a safety valve, a pressure relief valve and an oil regulator, which ensures maximum safety and smooth linear loading. The machine can be supplied with standard automatic power pack, dual stage, controlled by TCM200
LCD DATA ACQUISITION CONTROL SYSTEM
TCM200 Touch Control Unit is designed to perform automatically compression strength tests of construction materials such as concrete pipes by controlling the Testmak automatic compression pipe testing machines.
All the operations of TCM200 Touch are controlled from the front panel touch screen display.
TCM200 Touch Control Unit has easy to use menu options. It displays all menu option listings simultaneously, allowing the operator to access the required option in a seemless manner to activate the option or enter a numeric value to set the test parameters. Digital graphic display is able to draw real-time “Load vs. Time”, or “Stress vs. Time” graphics. Can do calibration easily from 10 points. Manual Control is available.
The Data Acquisition Control provides real-time graphical indication. Automatically determines the load rate in accordance with the international standards upon sample type. With the STOP and START buttons, the test will automatically stop or start.
LCD Data Acquisition Control System has different units are available (kN / kgf / lbf). Can do Automatic Load Rate upon Sample Type. Total load and also per area are given. and has real time graph indication. Stops Automatically, when Test is completed. Test results can be send printer to with software or from the thermal printer.
