Static Constant Loading Tester for Thermoplastic Manhole Features 

• Gate-type structure with super high rigidity, test speed can be controlled in a wide range, seamless ball bearing ensures high accuracy and stable performance.
• Digital AC servo system has been introduced, piecewise linear correction method ensures high accuracy and stability of system.
• Bridge structure of load sensors avoids side loading especially for big pipes.
• Unique type inner diameter measuring system tracks the deformation of inner diameter. It is easy to install sample and carry out measurement
• With protection functions of overload, over current, over force as well as over temperature, also multi protection methods have been set in mechanical & electrical part and software system.
• Module design satisfies customers’ requirement on extended function. Compression, bending, Ring stiffness, Ring flexibility, Flatten, Shear and Creep ratio tests can also be carried out on this tester.
• The system is highly intellectualized, whole test procedure will be recorded automatically.

Static Constant Loading Tester for Thermoplastic Manhole

QualiSCLT-Series Static Constant Loading Tester is mainly used to determine the resistance to the axial static constant load of plastic manhole. A constant force is steadily loaded on the axial direction of the manhole for the specified time, when the test is finished, observing the sample appearance (deformation, collapse, crack or crazing), determine the deformation in axial direction and calculate the deformation ratio of manhole. The machine is also suitable for ring stiffness test, flattening test, ring softness test of thermoplastic pipes.

BS EN 13598-1:2003 Plastics piping systems for non-pressure underground drainage and sewerage. Unplasticized poly (vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE). Specifications for ancillary fittings including shallow inspection chambers. It gives definitions and requirements for ancillary fittings of PVC-U, PP, and PE that can be used in non-pressure underground drainage and sewerage systems either outside the building structure or buried in ground within the building structure.
