American Petroleum Institute (API) recommends a maximum pressure drop of 3%. This should be taken into account when sizing valves higher pressure drops not only cause reduced flow but also cause quick damage to the valve due to chatter, especially when the blowdown is set below the effective pressure drop. Therefore, always try to obtain short and simple inlet piping. Complex inlet piping is only effective if the piping is at least one or two pipe sizes larger than the SRV inlet and its size is reduced just before the SRV inlet.

DICK S method of commercial production (3855) is too complex and the simpler method, credited to Nordhausen (3858) is too sketchy. It is also impractical, although you can easily modify the multi-flask method I found in the AMERICAN MECHANICAL DICTIONARY. 1876, to a one flask setup if you want to try it.

Figure 31. A model system developed by Parkin and co-workers (a), Tris(2-mercapto-l-phenylimidazolyl)hydroborato lead complex, [Tm ]Pb [C104] (197), is strikingly similar in structure to the lead bound in the active site of the target protein ALAD (b), (only lead and coordinated cysteines are shown) (245). In both systems, lead is bound in a trigonal pyramidal geometry by three sulfurs. Metal-binding studies on the model system (198) and inhibition studies on the enzyme reveal that lead has a higher affinity for this type of site than the native zinc ion.
