Rapid Crack Propagation Tester Standards:
- ISO 13477 Thermoplastics pipes for the conveyance of fluids Determination of resistance to rapid crack propagation (RCP) —Small-scale steady-state test (S4 test)
Rapid Crack Propagation Tester Features:
Features for RCP Test Unit
- The energy storage device, designed to convert elastic potential energy into kinetic energy, the impact speed can be controlled between 1m/s and 20m/s.
- The industrial control terminal is introduced and a colorful touch screen provides abundant information to the operator, e.g. sample pretreatment time, impact speed, test temperature, etc.
- Fast pressure filling and accurate pressure control. For pipes DN 200 to DN 500, setting pressure can arrive within 1min.
- High rigid frame enhances the bearing strength of the system and multiple buffers in the frame reduce the impact force from the high-velocity striker so that the component connection keeps perfect after repeated trials.
- High-efficiency and reliable energy storage system. An 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 save time and have 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.
Features for RCP Low-Temperature Conditioning Cabinet
- Automatically activated doors are provided. For time-saving reasons, the assembly goes into and out of the condition 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 automatically.
- There are independent sample delivery rails for cooling stations. Unique sealing design for the cabinet avoids freezing phenomenon between sealing strip and cabinet.
- Excellent thermal insulation system helps to enhance security and save power consumption.
- Multiple safety protection systems, including escape and alarm devices for the operator.
Features for RCP Sample Delivery Unit
As the standard laying down the “Crack initiation shall follow within 3min of removal of the test pipe from the conditioning”, limited time is available to position the 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, samples can be picked up from the conditioning cabinet within the 30s.
- PLC control terminal and colorful touch screen. Integrated monitoring during testing and provides customers more information, such as cooling temperature, pretreatment time, sample inlet & outlet, etc.
Features for RCP Enclosure
It consists of front & rear sealing parts, limiting rings, baffles, O-ring, etc. A variety of specification are selected, including Φ63mm, Φ110mm, Φ160mm, Φ250mm, Φ315mm, Φ400mm andΦ500mm.
- Seal parts, limiting 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 are on the test pipe.
- Unique design makes the weight much lighter and with higher rigid which can bear 3 Mpa pressure.
- The perfect structure ensures easy mounting and good sealing. It is also fast and easy to change to another pipe size of SDR.
