ISO 13477
Rapid Crack Propagation (RCP) Tester QT-RCP Series is designed to determine the critical pressure or critical temperature for rapid crack propagation of plastic pipe, PVC or other relevant materials. QT-RCP Series is a full set of testing machine consist of RCP Test Unit, RCP Low Temperature Conditioning Cabinet, RCP Sample Delivery Unit and RCP End Caps.
ISO 13477 Thermoplastics pipes for the conveyance of fluids — Determination of resistance to rapid crack propagation (RCP) — Small-scale steady-state test (S4 test), is applicable to the assessment of the performance of thermoplastics pipes intended for the supply of gases or liquids. In the latter case, air can also be present in the pipe.
QT-RCP-TU – RCP Test Unit
Rational structure and accurate impact speed. There is an energy storage device in the unit, it convert elastic potential energy into kinetic energy，than the impact speed range can be controlled between 1m/s and 20m/s.
Unit comes with the industrial control terminal and colorful touch screen which provides more information to operator, such as sample pre-treatment time, pipe inside current pressure, impact speed, length of crack and test temperature, etc.
Fast pressure filling and accurate pressure control. For pipes DN200 to DN500, setting pressure can be arrived within 30s and thanks to the module design, unit can be upgraded to suit different sizes pipes.
High rigid frame enhance the bearing strength of system and multiple buffers in the frame reduce impact force from the high velocity striker, so that the component connection keep perfect after repeated trials.
High-efficiency and reliable energy storage system. Energy storage system with a high storage speed and striker lifting system can be locked firmly or released quickly.
The easily adjustable support and the simple assembly & positioning system with quick coupling saves time and has proved to work outstandingly well in operation with samples.
Automatic security confirmation system. It means the correct locations of the test sample and the striker blade are identified automatically, so that the collision of the sample assembly with the striker blade is prohibited and the blade will not be released when the sample is not in position.
QT-RCP-CC – RCP Low Temperature Conditioning Cabinet
Automatically-activated doors are provided. For time-saving reasons, the assembly goes into and out of the conditioning cabinet through the pneumatic opening door.
Ultralow temperature and high efficiency. Temperature can drop to -30 within 10min and multiple groups of samples can be treated simultaneously. Temperature can be monitored and regulated automatically.
There are independent sample delivery rails for cooling stations. Unique sealing design for the cabinet avoid freezing phenomenon between sealing strip and cabinet.
Excellent thermal insulation system helps to enhance the security and save power consumption.
Multiple safety protection systems, including escape and alarm device for operator.
QT-RCP-SD – RCP Sample Delivery Unit
According to the standard laying down “crack initiation shall follow within 3 minutes of removal of the test pipe from the conditioning”. Limited time is available to position test sample and to increase the internal pressure. For this reason we offer a complete electric sample delivery unit.
High accuracy and high delivery speed. Thanks to the positioning system and automatic driven system, sample can be picked up from the conditioning cabinet within 30s.PLC control terminal and colorful touch screen. Integrated monitoring during testing and provides customer more information, such as cooling temperature, pre-treatment time, sample inlet& outlet, etc.
QT-RCP-EC – RCP End Caps
RCP End Caps consists of front & rear sealing part, limiting ring, baffles, O-rings, etc. A variety of specifications are selected, including Φ63mm, Φ110mm, Φ160mm, Φ250mm, Φ315mm, Φ400mm and Φ500mm.
Seal parts, limitation ring and internal baffles are connected to each other, together with sample shall be fixed on the v-support on sample supporting seat. So that blade can impact the slotted area on test pipe.
Unique design makes the weight much lighter and with higher rigid which can bear 3 MPa pressure. Patented structure ensures easy mounting and perfect sealing. It is also fast and easy to change to another pipe size or SDR.
