Classification of graphite tubes 1, according to the heating way: longitudinally heated graphite tube, transverse heating graphite tube 2, according to the performance: ordinary graphite tube (non thermal) for low temperature (less than or equal to 2000 DEG C) of atomic elements such as silver, cadmium and lead; pyrolytic graphite tubes for low, medium and high temperature (>2500 DEG C) atomic elements; suitable for middle and low temperature platform graphite tube (less than or equal to 2400 DEG C) atomization element. The function of graphite tube Atomic absorption spectrometry is according to the measured element in a gaseous atom has strong absorption effect and the establishment of the elements of the atomic resonance radiation. This method has the advantages of…
Graphite heat exchanger is a heat exchanger made of graphite for heat transfer component. The graphite to be used in the manufacture of heat exchanger is not transparent, and is commonly used in impregnated graphite and graphite. Graphite heat exchanger structure Graphite heat exchanger can be divided into 3 types: the structure can be divided into block hole type, tube shell type and plate type. The block hole type is composed of a plurality of blocks with a plurality of holes. Shell: shell and tube heat exchanger in graphite heat exchanger occupies an important position, according to the structure is divided into fixed and floating head two. Plate: made of graphite bonding plate heat exchanger. In addition, there are immersion,…
By pure graphite or metal plate (tooth plate, plate, net) reinforced graphite plate cutting or stamping, has many excellent sealing performance, such as thermal stability, self lubrication, corrosion resistance, not aging, not fragile, the use of long-term stability in the harsh working conditions, rarely need maintenance. Lining material with different metal plates. Typeoptionalwithoutedge, inneredge, outsourcing side, inside and outside wrapping. Graphite cut gasket is from pure graphite plate drilling or cutting and it has good corrosion resistance, high / low temperature, compression elasticity and high strength good, complex geometric gasket circular is widely used in all kinds of pipes, valves, pumps, pressure vessels, heat exchanger, and condenser generator, air compressor, exhaust pipe, refrigerator etc.. raw material An expandable graphite (graphite)…
