600 kN capacity Concrete Pipe Testing Machines are designed for the Peak Load Tests on Sewer and Drain Pipes, Concrete Pipes, Fittings, Cones on from 200 mm up to 2000 mm (outer diameters) pipes. Can be used for concrete pipes with a length up to 2000 mm.
Please contact with us for different dimensions and capacity of Concrete Pipe Testing Machines.
Concrete Pipe Testing Machines consist of;
• Load Frame
• Automatic Hydraulic Power Pack and
• Digital data acquisition & control system
The 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 300 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.
There are 2 options depending on frame fixing system, with or without chassis.First option is not including carrying chassis for the machine. These types of 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.Second option is including metal carrying chassis for the machine.
HYDRAULIC POWER PACK AND DIGITAL DATA ACQUISITION & CONTROL SYSTEM
HydraulicPower Pack
Automatic Hydraulic Power Pack, dual stage, controlled by digital readout unit is designed to supply the required oil to the load frames for loading.
Controller unit has a simple and compact configuration.
Very silent power pack can load the specimen between 1 kN/sec. to 20 kN/sec, with an accuracy of ±5%.
A Rapid approach pump is supplied as standard. Safety valve (maximum pressure valve) is used to avoid machine overloading.
Maximum working pressure of the system is 410 bar.
Dual Stage Pump
The dual stage pump is formed by two groups;
1. Low pressure gear pump
2. High pressure radial piston pump
On the dual stage pump, a high delivery, low pressure gear pump is used for rapid approach, while a low delivery, high pressure radial piston pump is used for test execution. The rapid approach facility shortens the time interval from piston start until the upper platen touches to the specimen. This excellent feature helps to save a lot of time when a large number of specimens are going to be tested.
Digital Data Acquisition& Control System
The unit is designed to control the machine and processing of data from load-cells and pressure transducers which are fitted to th machine.
All the operations of the unit is controlled from the front panel consisting of a LCD display and function keys.
The unit has easy to use menu options.
Digital graphic display unit loading rate of the time of Testing and load values can be monitored.
Digital graphic display is able to draw real-time “Load vs. Time”.
Software
The Concrete Pipe Testing Software is supplied free of charge with the Concrete Pipe Testing Machine.
Sample, company, laboratory and test values can be entered in the programme.
Load-time graphic, test reports and sample reports can be taken.
Software provides test data, results, and the load-time graphs can be seen at LCD screen.
The Concrete Pipe Testing Machine can be controlled (Start, Stop commands) by a computer with the software free of charge.
This software provides data acquisition and management for compression tests throughout the test execution.
The advanced functions for data base management provide an easy navigation of all saved data. The test results certificate includes all descriptive information.
Therefore, test parameters can be set and details about the test carried out such as client details, test type, specimen type, user info and other information required can be entered and printed out as well as test report and graph.
Software can be performed in Turkish and English.
Frequently used information like name and location of the laboratory, type and dimensions of mostly used specimens are held in memory and can be written automatically by right clicking on information boxes and selecting frequently used text in menu.
User can access any data of previously completed tests and use in his/ her new report since most of the tests have same structure and properties.
