Pipe Ring Stiffness Testing Machine

Pipe Ring Stiffness Testing Machine

Standard:

Meets the requirements of standards such as GB/T9647, ISO9969, ASTM D2122, EN 13476-1, etc.

Description:

The microcomputer controlled ring stiffness testing machine is suitable for testing the ring stiffness of pipes such as thermoplastic pipes, fiberglass steel pipes, double arm corrugated pipes, fiberglass sand pipes, wrapped pipes, polyethylene pipes, polyvinyl chloride pipes, PPR pipes, etc. Used for measuring a series of tests such as strong force, upper and lower yield strength, pressure, ring stiffness, ring flexibility, pipeline tension, pipeline creep ratio, etc. → Corrugated pipe ring stiffness test, pipe ring flexibility test, pipe flattening test, local lateral load test, stiffness test under uniform load of pipe, radial stiffness test deformation of pipe, continuous test of pipe creep ratio test (1000h/42d), and testing and research on mechanical performance indicators of pipe bending water equality. Longitudinal load performance test of plastic corrugated pipes; Performance testing of plastic corrugated pipe materials and tensile strength testing of pipes; Suitable for circular plastic corrugated pipes with a nominal diameter of DN10~DN1200mm, flat plastic corrugated pipes, prestressed metal corrugated pipes, circular metal corrugated pipes, flat metal corrugated pipes, standard metal corrugated pipes, reinforced metal corrugated pipes, metal spiral pipes, concrete filling pipes, corrugated pipes for anchor bolts, steel strip corrugated pipes, steel strip reinforced polyethylene spiral corrugated pipes, double wall corrugated pipes, composite material pipes, and special-shaped pipes. Petrochemical, power electronics, metallurgy and mining, papermaking, food and beverage, pharmaceutical industry, engineering, outdoor public buildings, residential communities, buildings, buried drainage/sewage/exhaust corrugated pipes, corrugated pipes for agricultural drainage, sleeves for communication cable threading, and corrugated pipes for buried industrial sewage pipelines.

Features：

PC control software, achieving screen display of test force, peak test force, beam displacement, test deformation, and test curve, making the operation intuitive and simple. Equipped with overload, overcurrent, and overvoltage protection functions, and equipped with a pipe inner diameter measurement system, it can accurately measure the changes in the inner diameter of the pipe. The transmission system controls a fully digital AC servo motor through a distributed control system composed of a PC and a microcontroller, driving the middle crossbeam up and down at the speed required by the test standard. The pressure is applied to the pipe sample through the sample pressure plate, and the force detection part adopts a segmented linear correction method to ensure the high accuracy and stability of the machine.
