Applicable to plastic pipe ring softness, ring stiffness, flatness, weld stretch, pipe creep ratio and other tests.

Model: XLS-50HG


Main function of the device

XLS-50HG series Microcomputer control Ring steelness testing machine adopts mechanical loading, electronic measurement, digital continuous speed regulation, and computer real-time control . 

The machine simultaneously displays the test force, displacement/speed digitally, and has the test force peak hold function. 

Applicable to plastic pipe ring softness, ring stiffness, flatness, weld stretch, pipe creep ratio and other tests. It is an ideal testing equipment for industrial and mining enterprises, research institutes, universities, commodity inspection and arbitration, and technical supervision.


Working principle

The ring stiffness is determined by the force value and deformation value that measured when the pipe is deformed at a constant speed. 


The tube sample was placed horizontally, the compression speed of the plate was determined according to the diameter of the tube, and the sample was applied with pressure perpendicular to the two parallel plates. 


The reaction force is generated during the deformation, and the ring stiffness is calculated by the force value when the tube sample has a deformation amount of 0.03 di in the diameter direction.


Experiments can be carried out according to GB, ASTM, DIN, ISO, JIS, BS and other standards.

Such as GB/T 9647-2015, GB/T 18477-2001,GB/T 16800-1997, GB/T1947,GB/T 165-2002,GB/T 838-1998, GB/T16491,GB/T5836 standard.


For structural wall tubes with spiral ribs, corrugations or other regular structures (special instructions are required to determine the span of the test machine), the length of the specimen shall be equal to (d i ± 20 mm, but not less than 290 mm, nor greater than 1000 mm)


Test machine manufacturing standard: GB/T 16491-2008 electronic universal testing machine
