net positive suction head available (NPSHA): NPSH determined by the purchaser for thepumping system with the liquid at the rated flow and normal pumping temperature

net positive suction head required (NPSHR): NPSH determined by supplier testing withwater. NPSHR is measured at the suction flange and corrected to the top of the foundation.NPSHR is the minimum NPSH at rated capacity required to prevent a head drop of more than3% (first-stage head in multistage pumps) caused by cavitation within the pump.

suction specific speed: An index of pump suction operating characteristics determined at theBEP with the maximum diameter impeller. Suction specific speed is an indicator of theNPSHR (defined in the following equation) for given values of capacity and rotating speedand provides an assessment of the pump’s susceptibility to internal recirculation. Suctionspecific speed is calculated by the following equation:

nqs = N(Q)0.5/(NPSHR)0.75

where:

nqs = suction specific speed

N = rotating speed in revolutions per minuteQ = flow per impeller eye, in cubic meters per second (gallons per

General Notes:a. For waters that may be in contact with hydrocarbons, purchaser shall indicate whether water is considered

sour. Purchaser shall indicate whether H2S is present (even in trace amounts).b. If ammonia is present from chemical-treating reactions or other sources, bronze internals shall not be used.c. Some types of waters described in the following Water Description Notes are not typically encountered in

refineries or process plants. However, these waters (or waters with similar corrosive elements) may bepumped in auxiliary or related plant systems, thereby justifying their inclusion to cover all user applications.

Water Description Notes:

1. Fresh potable water is assumed to be saturated or nearly saturated with oxygen and at a temperaturebelow 100°C (212°F). At a temperature above 100°C (212°F), water may become aggressive andunstable, requiring special material class based on water chemistry. Class A-1 is the lowest cost class,while A-2 offers extended life for increased initial cost.

2. Cooling tower water is assumed to be recirculating. Buildup or concentration of chlorides and othercontaminants is anticipated, especially if temperature exceeds approximately 93°C (200°F). Class A-3shall be considered for longer service life if sulfur compounds or free chlorine is present.

3. Condensate is assumed to be at a temperature below 100°C (212°F). At a temperature above 100°C(212°F), corrosiveness of water may vary widely and material class shall be based on water stability, pH,dissolved solids, and other water chemistry parameters.

4. Treated water is assumed to be noncorrosive, i.e., treated to control scaling, pH, and fouling (use ofbiocide or other additions). Caution shall be exercised in water chemistry control to avoid excessiveamounts of free chlorine.

5. Demineralized water is assumed to be low in chlorides and should be considered corrosive. Classes C-1and C-2 are based on considerations of minimizing corrosion and maintaining water purity. Class C-1 is a



cost-effective alternative, whereas C-2 may be readily available and offered as pump vendor standard.6. Seawater is assumed to be fully oxygenated, free-flowing, clean seawater, i.e., seawater does not contain

hydrocarbons and is not brackish bay water with excessively high chlorides and other contaminants.Seawater outside this definition requires special materials recommendations. Additionally, if flow rate isless than 1 m/s (3 ft/s) or is frequently stagnant, pitting may occur and special material recommendationsare required.

7. Foul water, water draw, and reflux streams vary widely in corrosivity. Class B-1 or more corrosion-resistantclasses may be required. Special material recommendations shall be obtained on the basis of expectedcontaminants.

8. Produced water is corrosive and defined as seawater (or similar high-chloride water from an aquifer) thathas been injected into an oil field and has then risen to the surface as an oil-water mixture from whichwater is removed and reinjected. Typical produced water is assumed to have H2S, possibly CO2, aminimum pH of 6.0, and maximum chlorides of 60,000 ppm. Class C-3 is normally a minimum, but classshall be based on purchaser-furnished water chemistry, temperature, and other parameters defined bypurchaser and supplier. Classes C-4 or C-5 may be required. Material temperature limits depend onspecific corrosive conditions.

9. Injection water is water injected into an oil-bearing formation to maintain formation pressure and enhanceoil recovery. Corrosiveness of injection water may vary widely because the water may be seawater,produced water, freshwater, or aquifer water with varying corrosivity. Typical injection water is high inchlorides and may contain H2S and CO2. Class C-3 is normally a minimum, but class shall be based onpurchaser-furnished water chemistry, temperature, and other parameters defined by purchaser andsupplier. Classes C-4 or C-5 may be required. Material temperature limits depend on specific corrosiveconditions.

10. Formation water is similar to produced water and is considered a highly saline water (brine). Formationwater comes from aquifers and other sources. Typically, formation water has high concentration ofchlorides (150,000 ppm or higher), possibly H2S, and nearly neutral pH. Material class shall be based onpurchaser-furnished water chemistry, temperature, and other parameters defined by purchaser andsupplier. Classes C-4, C-5, or other special materials beyond the scope of this Practice may be required.Material temperature limits depend on specific corrosive conditions.

Notes:(1) Mating wear surfaces of hardenable materials shall have a difference in Brinell hardness numbers (BHN)



of at least 50 BHN, unless both wear surfaces have BHN of 400 or higher.(2) Requirement for hard-facing and specific hard-facing material may be specified by the purchaser on data

sheets. Method of hard-facing application may also be specified by purchaser, or both material andmethod of application may be specified by mutual agreement between purchaser and suppler.Alternatives to hard-facing may include opening of running clearances and/or use of nongalling materials.

(3) Duplex (austenitic-ferritic) stainless steels are typically identified by trade name and have slightly varyingcomposition and corrosion-resistant properties. One of the most common wrought duplex steels(UNS 31803) has a nominal composition of 22% chromium, 5.5% nickel, 3% molybdenum, and 0.14%nitrogen.

(4) Super duplex stainless steels are distinguished from standard duplex steels (Note 3) by their increasedamounts of chromium (25% nominal) and other alloys, typically nickel, molybdenum, and nitrogen. Theyare most frequently designated by trade name with slightly varying compositions and specific corrosionresistance.

(5) 6-Moly (super austenitic) stainless steels are enhanced austenitic stainless steels that have maximumresistance to pitting and crevice corrosion. These steels are typically required for the most severeservices with high chloride concentrations. These steels are designated by trade name. Choice of aspecific steel shall be based on purchaser preference, mutual agreement between purchaser andsupplier, and/or specific corrosive conditions.

(6) Seal and vent piping shall be compatible with metallurgy of pump components. For classes A-1, A-2, andA-3, pipe shall conform to ASTM A106 Gr. B, and fittings shall conform to ASTM A105. For classes B-1,C-1, C-2, C-3, C-4, and C-5, pipe and fittings shall be made of an appropriate stainless steel for thecorrosivity of the system.

(7) Wetted fasteners shall be compatible with the pump metallurgy and corrosivity of the pumped water.Some materials, especially austenitic stainless steels, are prone to galling. Precautions are required toavoid this problem.

(8) For dry shaft designs, alternate metallurgies can be considered.(9) Suitable nonmetallic materials can be considered.
