Thermal Conductivity Tester for Tubular Materials
Published: 8/19/2015
The Thermal Conductivity Tester for Tubular Materials measures the thermal conductivity of high-density polystyrene outer pipes and polyurethane foam pre-insulated pipes. It is suitable for use in industries that require precise heat conduction measurements according to standards like CJ/7114-2000, GB10296-2008, and ISO/DIS 8497.
Product Description
The GHR-3K Thermal Conductivity Tester is designed for testing the thermal conductivity of tubular materials. It uses virtual instrument technology and is primarily used for measuring the thermal conductivity and heat transfer properties of high-density polystyrene and polyurethane foam pre-insulated pipes. The instrument complies with standards like GB10296-2008 and ISO/DIS 8497, ensuring precise and reliable thermal measurements.
The tester analyzes the heat exchange coefficient, thermal conductivity, and heat transfer characteristics of the tube surfaces. It employs a mathematical model based on the longitudinal heat flow of metallic materials and is designed with contemporary onsite technical requirements in mind.
