Since the metals used in the plug match the tube metals, the coefficient of expansion is the same and a permanent seal is insured.
At the same time, they have unique high performance characteristics not associated with OPC, such as greater chemical and thermal resistance, acid and alkali resistance, bacteria retardancy, maintenance of alkali condition and therefore retardation of oxidation and rust, water retardancy, a low coefficient of expansion, and other improved mechanical properties, according to Panitz.
]-volumetric coefficient of expansion with concentration
Its coefficient of expansion is 48 ppm/[degrees]F and viscosity is 35,000 cps at room temperature.
The addition of an anti-vein agent changes the thermal coefficient of expansion of the core sand to allow the veining defect to improve or not exist.
It has a very low coefficient of expansion," says Griffith.
Remember, the material often also acts as an underfill, cushioning the effects of thermal coefficient of expansion (TCE) differentials.
It also has virtually the same coefficient of expansion and contraction as carbon steel, making it the natural choice to return energy conservation to facilities by installing it over existing insulation systems.
