The Trouble Analysis and Processor of CT Tube;

Due to computed tomography tube is an expensive and consumable material, the tube replacing expense takes up a larger part of CT operation costs.

The preventive maintenance and daily application of Siemens Somatom Balance CT tube was recommended in this chapter.

The text analyses the main control theory of voltage and current of Xrays bulb tubes in Highfrequency Xrays Machine Then it introduces the design of hardware structure and software about the control system By the way, the design project has applied to the HK MCXLII moving highfrequency Xrays machin

Crack Defects of Metallic Mould in Nodular Iron Pipe Production;

Coating of Pouring Channel for Ductile Iron Pipe in Centrifugal Casting and Its Spraying Technology;

The principle of air bubble defect of polyurethane coating of ductile iron pipe was discussed that carbon dioxide created by the reactivity of the water of manufacture process and isocyanate is the key factor.

This paper introduces that it is used in the rebuilding of annealing furnace for spheroidal graphite cast pipe by flat_flame burner and two area controlling temperature.
