Carbon Fiber-Reinforced DIABON® Blocks for Improved Reliability Highly pretensioned carbon fibers are wrapped around the DIABON blocks. The high modulus of elasticity of the carbon fiber ensures that the tension on the reinforcement is retained even under sharply fluctuating load or stress surges – no fatigue is experienced. The DIABON HF carbon fiber reinforcement does not impair resistance to corrosion because its chemical resistance is identical to that of synthetic resin-impregnated graphite. Carbon fiber-reinforced block component Due to the carbon fiber’s negative coefficient of...

DIABON® Block Heat Exchangers Cylindrical Design DIABON block heat exchangers of this design consist of DIABON graphite blocks that incorporate horizontal and vertical passages. The blocks are stacked on a baseplate with corrosion-resistant gaskets between each. A steel shell fits over the block column and is bolted to the baseplate. The block column is secured by a top pressure plate bolted to the steel shell. The joint between the steel shell and top header is sealed with an O-ring to As a rule, the corrosive medium flows through the allow free movement of the shell. vertical passages of...
