8 BODIES/METALLURGY Size Range The Pure-Flo ® product line offers a complete line of Cast, Forged and Wrought bodies to meet the needs and requirements of your process application. The size range, dimensional standards, as well as stainless alloys available for the various body types are as follows: Cast Forged Wrought ANSI 1/2" - 6" Bio-Tek, 1/2"-3" 1/2" - 4"** DIN/ISO DN 15 - DN 50 DN 8 - DN 50 DN 15 - DN 100 + 316L Stainless Alloy ASTM A351 Grade CF 3M Dual certified to ASTM A479, 316L ASTM A182 Grade 316L,S9 DIN 17440, 1.4435 Dimensional Standards OD Tubing, Pipe, ISO/DIN OD Tubing, Pipe, OD Tubing, Pipe, ISO/DIN ISO/DIN/SMS ** 4" Pure-Flo bodies, Tank Bottom Valves, divert valves and any block bodied fabrications are standard. 1/2"-3" Pure-Flo bodies are nonstandard. + DN 65-100 Pure-Flo bodies are wrought as standard; sizes DN 15-50 Pure-Flo wrought bodies are nonstandard.
MANUFACTURING METHODS Castings: Pure-Flo bodies are produced utilizing the lost wax or investment cast method. A wax impression is created for the shape required. The wax impression is dipped or sprayed with ceramic material and then fired in a kiln. The wax evaporates leaving behind a hard ceramic shell into which molten material is poured. The solidification of molten metal may cause sub-surface porosity, which varies in occurrence depending on casting techniques, machining and interior finish specifications. The result is a product complete with flow path, bolt holes, drain marks and body identification marks cast into the required shape. Machining is, therefore, minimal. Ferrite content may vary considerably depending on several variables including wall thickness, metallurgy of the material, etc. Engineered Valves has established a specification of 12% norm based on ASTM A800 analysis techniques. Pure-Flo Castings go through a rigorous qualification program to ensure the highest attainable quality is achieved. The levels of porosity are the absolute minimum possible. Forgings: Pure-Flo bodies are produced from round stock or plate which has been processed from an ingot. The round stock or plate is compressed between two halves of a forging tool at elevated temperatures. The result is a shape which is then machined to create the shape required. Machining required is more extensive than a casting. Ferrite content for the ANSI Pure-Flo and ISO/DIN forged product lines is 0.5%. The ferrite measurement method employed by Engineered Valves is the more accurate and labor intensive metalographic technique of ASTM E- 562. Wrought: The 4" Pure-Flo wrought body, Tank Bottom Valves, divert valves and block body fabrications are produced from wrought material. Wrought material is worked material such as plate or round stock. Rather than forging a shape between two halves of a tool, as in the case of a forged body, the shape required is machined directly from wrought material. Ferrite content in wrought material may vary depending primarily on the metallurgy of the material used; however, most standard product is less than 3%. Ferrite: Ferrite can be defined as the ferromagnetic, body-centered, microstructural constituent of variable chemical composition in iron-chromium-nickel alloys. This may be formed upon solidification from molten metal (delta ferrite) or by transformation from austenite or sigma phase on cooling in the solid state (alpha ferrite). The formation of ferrite is therefore a natural occurrence in stainless alloy products. Ferrite levels can be determined utilizing several techniques including chemical analysis, metalographic examination and magnetic attraction. As one can see from the above comparisons, ferrite is depleted as the material is worked, i.e. castings having the highest content and forgings having the lowest. Free delta ferrite contained in components in a process system may or may not be of concern to the end user. The selection of process components in the Pharmaceutical/Bioprocessing Industry, especially in cell culture applications, demonstrates a distinct movement toward lower ferrite materials. It is important to note, however, in many applications, the use of higher ferrite content components may have no effect on the product, nor the service life and/or performance of the component while reducing the inherent cost of the component. The nature of the process, the utility protocols (i.e. passivation, cleaning, sterilization, fabrication), as well as additional surface preparation of the material such as electropolishing, will indeed have a bearing on the extent of the corrosion resistance of the component. Pure-Flo Solutions Group provides the customer a choice in body types based on the needs and requirements of a client’s process application. 9 BODIES/METALLURGY
