ABS Piping Australian Presentation
Ductile Mode
Does not fracture
Cracks at Nodes
Thermoplastic Piping Design
ABS and Other Thermoplastic Pipe Materials
International and national standards do not define the design
requirements adequately for thermoplastic pipe systems
Hoop stress the primary design parameter
Manufacturers are heavily relied upon to provide design assistance
ABS material properties vary between manufacturers and resin used
but are generally consistent to meet standards such as AS3518
Properties are isotropic
Thermal strain significant for applications
NDE technology is not widely available
Testing is defined
