Engineered Water Heating Solutions

introducing

AquaPLEX is: ...the engineered brand for potable water heating defined by:

Lean duplex stainless steel alloy material ASME section IV, IV part HLW, and VIII code certified products Engineering design control of fabricated materials Specialized metal cutting technology State of the art welding technology Immersion pickling and passivation processing

AquaPLEX is:◦ Lean Duplex stainless steel alloy

Lean = high chromium, low nickel, other elements for enhanced corrosion resistance

Duplex = Austenitic (300 series) and Ferritic (400 series) grain structures combined for strength and corrosion resistance to chloride stress cracking

Grain structure

AquaPLEX is:◦ ASME section IV, IV part HLW and VIII code certification

Material certification Design certification Welding certification Pressure vessel certification

Every pressure vessel is code stamped after fabrication

AquaPLEX is:◦ Engineering design control of fabricated materials

ASME construction requirements (calculated strength values)

Joint designs to prevent crevice corrosion formation

A crevice is defined as two adjoining materials with the attachment joint that is > 2x depth to width ratio crevice No crevice

AquaPLEX is:

◦ Specialized cutting technology Waterjet cutting with 3-axis (vertical) and 5-axis (beveled) cutting heads

50,000 psi water and diamond dust with no residual heat signature

AquaPLEX is:

◦ State of the art welding technology Synergic twin pulse robotic welding practices

robotic welding tip tig manual/auto feed welding

AquaPLEX is:◦ Full immersion pickling

4-5% HF @ 105F @ 60 min

removal of heat tint

restores chromium depleted layer from welding processes

Restores 50/50 ratio material grain structure post-welding

AquaPLEX is:◦ Full immersion passivation

20% HNO3 @ 105F @ 60 min

Restores chromium oxide layer on all metal surfaces

2-3mm surface finish prevents development of corrosion from potable water

Water reactivates chromium oxide layer, keeps corrosion resistance properties intact

AquaPLEX is: Lean duplex stainless steel alloy material

ASME section IV, IV part HLW, and VIII code certified products

Engineered joint design control of fabricated materials

Waterjet cutting via 3 and 5 axis heads with no heat signature

Synergic pulse and TipTig welding technology

Immersion pickling and passivation processing

Compromise is not acceptable – no single point of failure allowed

AquaPLEX is:Not just material – it’s the design, fabrication and processing that makes an excellent choice of material better!

10 year warranty including chloride stress cracking

Gas fired heat exchangers and tanks for all energy source storage water heaters
