Thermal Cycling Test Stand for Pipes and Fittings-3S

The temperature cycling tester is designed to determine the resistance of thermoplastic pipe network and connections consisting of stiff or flexible parts to alternating thermal shock. This applies to pipe systems intended to be used for conveying hot and cold pressurized water. Thermal Recycling Testers for Plastic Pipes is used to evaluate the function of hot and cold water-pipes PP，PE-X, PVC-C, PB), under a certain pressure for 5000 cycles. A test assembly of pipes and fittings is subjected to temperature cycling by the passage of water under pressure using hot and cold water alternately for a specified number of cycles. While being subjected to temperature cycling parts of the assembly of pipes and fittings are maintained under tensile stress and/or flexural strain by the use of static clamps. ASTM F 1335-98 Standard Specification for Pressure-rated Composite Pipe and Fittings for Elevated Temperature Service. The standard covers pressure-rated composite pipe and fittings for the transport of hot or cold liquids, beverages, or gases that are compatible with the composite pipe and fittings. Composite pipe is produced using a butt welded aluminum pipe as a core, with an extruded inside layer of crosslinked polyethylene (PEX) or polyethylene (PE). An adhesive layer is used to bond the inside layer to the wall of the aluminum pipe. An outer layer of polyethylene (PE) and an adhesive layer are extruded to the outer wall of the aluminum pipe.
