Overview

The circumferential tensile testing machine is a testing equipment specifically designed to measure the circumferential (circumferential) tensile properties of materials such as pipes. The device is fixed with two semicircles, with one end moving and stretching to break, and the software automatically records the values!

Product Details

1、 Product Introduction:

The circumferential tensile testing machine is mainly used for evaluating‌pipe material、Cable protection, fiberglass pipeMechanical properties of cylindrical products under circumferential stress, such asCircumferential tensile strength、yield point、elongationandmodulus of elasticityIt measures the load-bearing capacity and deformation behavior of the specimen in the circumferential direction by applying a tensile load.

IIMain implementation methods‌The circumferential tensile test can be achieved through two mainstream methods.

‌Method 1: Adapt the testing machine to specialized fixtures‌: Using high precision‌Electronic testing machine‌As the loading subject, through adaptation‌Circumferential stretching fixture‌
(such as specially designed clamping devices) to achieve testing functions. This method has high flexibility, and one testing machine can perform multiple tests. ‌‌
‌Method 2: DedicatedCircumferential tensile testing device‌Part of the design adopts independent‌Circumferential tensile testing device‌Its core includes an adjustable diameter wheel rim structure. pass‌Adjust the length of the spokes connecting the wheel rim and the center plate‌

The diameter of the wheel rim can be changed to accommodate different inner diameter pipe samples, and then a tensile machine can be used to apply tension for testing. ‌‌

‌Key technical parameters

‌

The performance of the circumferential tensile testing machine is mainly determined by the following parameters.

‌Load capacity and accuracy‌According to the sample specifications, the required equipment‌The load capacity is usually between 100kN and 1000kN‌The accuracy of force measurement needs to be within‌Within ± 1%‌The accuracy of the displacement measurement system should reach‌Level 0.5‌The force accuracy of the equipment can reach‌± 0.5% or even higher‌

‌Speed and Control‌The speed range of the crossbeam movement needs to be wide enough, for example‌0.05 to 500 mm/min‌To meet the loading rate requirements specified by different materials or standards. The device should support‌Multiple closed-loop control modes such as stress, strain, displacement, etc‌
Ensure a smooth and accurate loading process. ‌‌
‌data acquisition and processing‌The equipment needs to have‌High data sampling rate‌

It can record real-time load, displacement, and deformation data, and automatically calculate key parameters such as elastic modulus, yield strength, tensile strength, and elongation at break by software. ‌

‌Main standards followed‌
When conducting circumferential tensile testing, it is necessary to strictly comply with relevant international and national standards to ensure comparability and reliability of the data.

‌ASTM D2290-19‌This is‌Plastic pipe circumferential tensile properties‌
The standard testing method specifies in detail the procedures for determining strength, elongation, and modulus. ‌‌
‌ISO 1167-1:2019‌This international standard covers the evaluation through circumferential tensile testing‌Internal pressure resistance of thermoplastic pipes‌
The method. ‌‌
‌GB/T 1040.1-2025‌Chinese National Standards for‌Determination of Plastic Tensile Properties‌

Clear requirements have been put forward for the accuracy and speed range of the testing machine. ‌‌
