Description
Summary:The peculiarities of technological processes of obtaining steel castings of shut-off valves by lost foam casting are described. It is shown that the dimensional accuracy of the casting «Valve Body DN80» exceeds 7-th accuracy class; the surface quality, mechanical properties and chemical composition of the steel completely meet the customer requirements. The test procedure for leakproofness of shut-off valves castings is given.
