4 UGITECH Our ambition: optimize our positions on the world markets : 2 main markets Strong presence in Europe and a ambition to develop Export 2008 figures 2008 figures 4

5 UGITECH A wide range of products to answer the customer demand: Round Bars Hexagonal Wire rod Drawn wire Bars 5

6 UGITECH. Three key factors of success which make the difference: CUSTOMIZATION : Thanks to commercial and technical assistance for the customers needs; INNOVATION : Through a policy of our offer s evolution (product / service) and strong skills in marketing and R&D; RELIABILITY : With a single streams management and an unique control system ( SAP). 6

7 Why stainless steel grades in pump and valve systems? Corrosion resistance in Process Industries (Oil & Gas, Chemicals, Waste and Salt water, etc.); Pressure and Temperature resistance; Hygienic requirements in Food & Beverage Industries (Chocolate, Drinking water, Wine, Milk, etc.); Life cycle cost (Low maintenance costs). 7

8 Which stainless steel grades in pump and valve systems? Standard grades : FERRITIC STEELS ( ) : Magnetic Low strain hardening coefficient Good tensile strength at high temperature MARTENSITIC STEELS ( > > ) : Magnetic High mechanical properties AUSTENITIC STEELS (1.4307/ / ) : Not or slightly magnetic Good impact test even at low temperature 8

9 Which stainless steel grades in pump and valve system? Special grades : DUPLEX STEELS ( ) : Excellent corrosion resistance High mechanical properties SUPER AUSTENITIC STEELS ( ) : Very high stress corrosion resistance HEAT RESISTING STEELS ( ) : Austenitic steel with a good oxidation resistance PRECIPITATION HARDENING STEELS ( ) : Very high mechanical properties Good corrosion resistance 9

10 Many pumps with a wide range of requirements Irrigation Pumps : Use: Pump water from ground wells Requirements: Corrosion resistance in water Parts: Shafts Grades:

11 Many pumps with a wide range of requirements Centrifugal Pumps: Use: Pump for low viscosity materials (water, oil, etc.) Requirements: Corrosion resistance in wastewater, chemicals, etc. Hygienic for food industries Parts: Shafts and fasteners Grades: (For oil and chemicals) (For others) 11

12 Many pumps with a wide range of requirements Progressing Cavity Pumps: Use: Pump for very viscous materials Requirements: Corrosion resistance in process industries (oil, chemicals, thick sludges in water treatment). Hygienic for food industries (honey, chocolate) Parts: Rotors, flanges, fasteners, mechanical seal, seats Grades: (For oil and chemicals) High machinability grades (UGIMA ) 12

13 Various valves to regulate various fluid flows Butterfly valves : Use: Large flow at low pressure Requirements: Corrosion resistance in process industries (gas and liquid). Hygienic for food industries Parts: Stem, pins, butterfly, body (sometimes) Grades: > High machinability grades (UGIMA ) 13

14 Various valves to regulate various fluid flows Ball valves : Use: Gases or liquids with suspended solids (slurries) Requirements: Corrosion resistance in process industries (chemicals). Parts: Ball, stem, seals, bush, stud, nuts, body Grades: > High machinability grades (UGIMA ) 14

15 Various valves to regulate various fluid flows Solenoid valves : Use: Liquid, gases, oil (open and close by electric drive) Requirements: Corrosion resistance Hygienic for food industries Magnetic grades Parts: Plunger, spring, body Grades: / (For body) Si B (For plunger) High machinability grades (UGIMA ) 15

16 Other compatible parts to complete pump and valve systems. Fittings & Quick couplings: Use: All fluids (liquids and gases) Requirements: Corrosion resistance Parts: All parts (usually from hexagonal bars) Grades: / High machinability grades (UGIMA ) 16

17 Other compatible parts to complete pump and valve systems Flanges: Use: For large pipes (liquids and gases) To connect valves with pumps, with pipes Requirements: Corrosion resistance (same as pipes) Hot forgeability Parts: Full parts Grades: /

18 Other compatible parts to complete pump and valve systems Screens: Use: Filtration system in oil production or irrigation. Requirements: Abrasion resistance Corrosion resistance (of spot welded areas too) Weldability Parts: Screens Grades: / Drawn wire and profiles 18
