Ring stiffness tester

Characters

Double-column high-rigidity structure with a wide speed control range.

Advanced closed-loop AC servo control system ensures high precision and stability. A high-resolution AD sampling circuit captures test data accurately, ensuring that even peak values are retained.

Two or four load cells connected in a bridge configuration enhance resistance to lateral deflection during large-diameter pipe testing, while reducing the risk of sensor damage.

Innovative inner diameter measuring system simplifies specimen installation and enables direct, accurate measurement.

Comprehensive multi-level protection integrates mechanical, electrical, and software safeguards, including overload, overcurrent, and overtemperature protection.

Pipe creep rate test function (optional)

This function is used to determine the creep rate of thermoplastic pipes having circular cross-section. Long-term Ring stiffness may be calculated according to the parameter of creep rate.

2.Fluctuation of dead load force value: ± 1%

3.Timing range: 1--9999h59min59s

4.Timing resolution: 1s

Applications: PE/PPR/PVC/PERT Pipe factory outgoing inspection, scientific research, production R&D, teaching and training, third-party testing centers.

Ring Stiffness Tester FAQ

1. How to choose the right ring stiffness tester?

Selection is mainly based on two factors: first, determine the tester height according to the maximum pipe diameter you produce; second, calculate the required maximum test force based on the pipe's ring stiffness grade to determine the appropriate load capacity (tonnage). We recommend providing your pipe specifications prior to selection so that we can recommend the most suitable model for your needs.

2. Can the Starlink-test ring stiffness tester also perform ring flexibility tests?

Yes. Our tester supports continuous testing for both ring stiffness and ring flexibility. After the ring stiffness test is completed, the equipment automatically switches to the ring flexibility test without the need for re-clamping, ensuring a smooth and efficient process.

3. What are the laboratory space requirements for the ring stiffness tester?

The overall height of a ring stiffness tester is generally above 3 meters, so the laboratory's clear height is a critical consideration. Additionally, due to the equipment's heavy weight, sufficient space must be reserved for hoisting equipment during installation, and the floor load-bearing capacity must meet the requirements. We recommend discussing your laboratory conditions with us prior to ordering so that we can provide a reasonable installation plan.

4. Can the ring stiffness tester also perform tensile tests?

Yes. Our tester can be equipped with a tensile testing function upon request. With the appropriate tensile fixtures, it can perform pipe tensile tests, achieving a multi-purpose machine.

5. Can the StarLink ring stiffness tester perform creep ratio tests?

Creep ratio testing is an optional feature and must be confirmed prior to ordering. This function requires additional hardware and software modules. We can customize the configuration according to your specific needs.

6. How can I purchase a ring stiffness tester?

You can contact our customer service directly with your testing requirements and pipe specifications. We will recommend the most suitable configuration and provide a detailed quotation. We look forward to hearing from you!
