Compressive strength of heat exchanger tube


Compressive strength of heat exchanger tube

     Foreign companies are using impregnated graphite tube, pipe specifications for? 50mm × 7mm. After the second high-temperature graphite graphite carbon tube, pipe internal heat exchanger has many small gaps, through the vacuum impregnation process, the gap was filled resin, good permeability resistance, tensile strength than the domestic high-pressure graphite tube . Because a high degree of graphite, so as the heat exchanger material, such heat exchangers have higher heat transfer coefficient, but the bending strength (vertical), the compressive strength slightly lower than the pressure-type graphite tube.

  1. With the development of the whole technique, China glass reactor is greatly developed. From here: www.toption-china.com/reactors-and-instruments/chemical-synthesis-reactor-series.And a lot of different types of reactors may begin to be produced. Meanwhile, these reactors equipments are widely applied to industry of chemicals, food, paint, silicon, medicals and so on.
