Either way, adding additional heat-emitters can help even with a cast-iron boiler. You can utilize a lower supply water temperature. You will need to utilize a control, mixing and sensor strategy to keep return temps above condensing level (~ degrees) in a cast-iron boiler. Doing so will allow you to take full advantage of an outdoor reset. The absence of apparent effect of gas pressure generated in moulding sandon the surface quality of iron castings is quite understandable as the pressure of this gas is but ona very smallly percent fraction of the metallostatic pressure, and the value of Pa corresponds to the cast iron pressure at a depth of about 3 Size: KB.

ISO is not the only standard for grey cast iron. In can be ordered to the Euronorm standard BS EN where there is a very similar range of grades. There are also comparable standards in the ASTM, DIN and SAE ranges. Other national standards exist along with various trade named standards, most of which are obsolete, the exception. resistant cast iron and are designed for easy replacement. Heavy In general, abrasive velocity (approximately feet per second) and volume of abrasive are such that mechanical systems provide a high level of work capacity per unit time. As a result, mechanical blast cabinet equipment can be geared to medium to high production applications.
