Application of hydraulic universal testing machine in grooved pipe joints

The mechanical properties test of grooved pipe joints usually uses Jinan Hengsi Shanda HydraulicUniversal testing machineThe test is carried out, and the equipment is mainly used for the tensile force detection of grooved pipe joints in automatic sprinkler fire extinguishing systems.
The testing items are as follows:
Natural rubber sealing ring: tensile strength, pull-off elongation, tensile change strength rate, elongation change rate, compression deformation
EPDM rubber sealing ring: tensile strength, pull-off elongation, tensile change strength rate, elongation change rate, compression deformation
Dingqing rubber sealing ring: tensile strength, pull-off elongation, tensile change strength rate, elongation change rate, compression deformation
Silicone rubber sealing ring: tensile strength, pull-off elongation, tensile change strength rate, elongation change rate, compression deformation
Grooved pipe joint (clutch): including the compressive strength and elongation gap of bolts and nuts
Grooved pipe fittings: compressive strength
