The electric heating body of the graphite rod is used in high temperature vacuum furnace, and the highest temperature can reach 3000. Impregnated graphite rods can be used with Maximum use temperature 3000℃ with Resistance coefficient(8~13)×10-6 Ω•m and higher Thermal conductivity Its thermal expansion coefficient is small, high thermal conductivity, resistance coefficient for (8-13) * 10-6 ohm - m, processing is SiC and MoSi2 good, resistant to high temperature, extreme heat and good resistance, the price is cheap. Application domain:。 Carbon and graphite products is widely used machinery, electronics, semiconductor, silicon, metallurgy, petroleum, chemical, textile, electric motor, electrical appliance, electric furnace, transportation, communication, aviation, atomic energy, medicine, food, biological engineering and other fields, in order to give full play to…
Graphite self sealing ring consists of low sulfur expandable graphite by moulding, precise size, density can be determined, and without any additional filler or adhesive. Graphite purity greater than 98%, do not need to carry out anti-corrosion treatment. Generally, the cross section of the packing ring is square, and it can also be wedge shaped or V shaped, and the two parts can be used for high pressure.

Graphite heat exchanger is a heat transfer device made of graphite. The graphite in the manufacture of heat exchanger should be non transparent, and is often used in the non - permeable graphite and graphite. Structure The graphite heat exchanger can be divided into 3 types: block type, tube shell and plate type according to its structure. A piece of hole: a plurality of bulk graphite assemblies that are formed by a plurality of holes. Shell and tube type: tube shell type heat exchanger in graphite for heat exchanger occupies an important position, according to the structure is divided into two kinds of fixed and floating head. Plate: made of graphite bonding plate heat exchanger. In addition, there are immersion,…
