Accessoriess

1. Standard Included Accessories

Multi-specification high-strength clamps: Suitable for DN100~DN600 (or larger diameter) pipes, made of alloy steel with an anti-deformation design, used to securely clamp large-diameter samples and prevent displacement during testing.

Large-diameter sealing components: Fluororubber/polyurethane material, suitable for end-face sealing requirements of different pipe diameters, resistant to high pressure and corrosion, ensuring no leakage of the test medium.

High-precision pressure sensor: Accuracy ±0.1% FS, range covering 0~60MPa (or customized), real-time monitoring of test pressure to ensure data accuracy.

High-pressure connecting pipelines: Stainless steel material, pressure rating matching the sensor range, used to transport the test medium (water/oil) and connect the sample to the pressure system.

Sample size measurement tools: Digital caliper (range 0~500mm), wall thickness gauge, used to measure the outer diameter, wall thickness, and other basic parameters of large-diameter samples.

Safety protection devices: Explosion-proof glass observation window, emergency pressure relief valve, overload protection switch, ensuring safety during the testing process and avoiding high-pressure risks.

Operation manual + calibration certificate: Includes equipment operation and maintenance instructions and factory calibration records, guiding standardized use and qualification traceability.

Spare sealing gaskets and O-rings: Consumable parts of the same specifications as the sealing components, used to replace aging or damaged sealing parts.

2. Optional/Spare Accessories

Extra-large diameter customized clamps: Suitable for special pipe diameter samples above DN600. meeting non-standard large-diameter testing needs.

Medium filtration and circulation system: Filters impurities in the test medium, enabling medium recycling and reducing testing costs.

Data acquisition software: Supports real-time data curve plotting and data export (Excel/PDF), facilitating test data traceability and analysis.

Spare pressure sensor and pressure relief valve: Quickly replace faulty components, reducing equipment downtime.

Sample support bracket: Used to assist in the installation of extra-long/extra-heavy large-diameter samples, facilitating clamp positioning.

Test Procedures

1. Pre-test Preparation

Check that the equipment power supply, hydraulic system, and high-pressure pipeline connections are normal, replenish the test medium (deionized water/special hydraulic oil), and confirm that the emergency pressure relief valve is closed; calibrate the pressure sensor, and clean the surfaces of the fixtures and seals.

2. Specimen Preparation and Installation

Cut the large-diameter specimen according to the test standard, measure and record parameters such as outer diameter, wall thickness, and length; select the appropriate fixture and sealing components, place the specimen smoothly into the fixture, adjust the position to ensure that the specimen axis is consistent with the direction of force, evenly tighten the fixture, and pre-pressurize with low-pressure medium to check the sealing performance.

3. Parameter Setting

Set the test mode (burst test/hydrostatic pressure holding test), pressure increase rate (e.g., 1 MPa/min), and target pressure (or pressure holding time) through the control panel; enable the data acquisition function, and save the parameters after confirming their accuracy.

4. Safety Confirmation and Start

Close the test chamber protective door, and ensure that the operators have evacuated the safe area; press the start button, and the equipment will automatically increase the pressure at the set rate, monitoring the panel pressure data and specimen status in real time.

5. Test Monitoring

During the pressure increase process, observe whether there is leakage in the pipeline or loosening of the fixture, and record the pressure change curve; for burst tests, focus on the burst pressure value at the moment of specimen rupture; for pressure holding tests, maintain the set pressure for the specified duration and monitor pressure stability.

6. Test Completion and Cleaning

After the specimen ruptures in a burst test, the equipment automatically releases the pressure; after the pressure holding test reaches the set duration, manually start the pressure release procedure (slow pressure release to avoid impact); after the pressure drops to atmospheric pressure, open the fixture and remove the specimen, and record the test results (burst pressure, whether the pressure holding is qualified, etc.); clean the fixtures, seals, and test chamber, drain the residual medium, turn off the equipment power, organize the test data, and generate a report.
