Additional Factors

Environmental Hazards: Corrosion

Stainless steel ACO Pipe is offered in non-magnetic austenitic stainless steel grade 316L. All products are
pickled and passivated; parts can be electropolished to special order.

Environmental Hazards: Temperature

Applications with high ambient or high fluid temperatures are ideal for stainless steel pipe systems as they
offer a low coefficient of thermal expansion:

0.01188 in/ft (0.99 mm/m) with a temperature change of 140°F (60°C).

Flow Capacity

ACO Pipe comes in a wide range of sizes to meet most projects needs (see above). View Technical
Documents for flow tables.

Operating Pressure

ACO Pipe is tested and approved for operating pressures in all gravity, syphonic and vacuum systems and is
designed for a maximum working pressure between -11.6 psi to 7.25 psi (-0.8 to 0.5 bar).

ACO Pipes and fittings are equipped with an EPDM double seal, which is removable for ease of replacement.
FPM and NBR seals are available. Socket clamps are also available for extreme pressure environments.

Features & Benefits

HygieneFirst

Drainage systems are a particularly important niche for the persistence of listeria and can be a source of food contamination. Poorly specified drainage leads to costly ongoing cleaning and maintenance, and at worst it can result in food contamination.

ACO Pipe benefits from ACO’s HygieneFirst philosophy: manufacturing products with factors that help ensure health and safety of workers, product, and the local environment.

Smooth welding surface quality along with pickling and passivation of all stainless steel products within the ACO Pipe system safeguards against corrosion and allows for easy cleaning.

Seals within ACO Pipe and fittings are available in materials with a variety of resistances, as well.

ACO Pipe is available in various lengths to minimize the amount of connections necessary and further reduce the amount of weaker points within the piping system.

Comprehensive Range

ACO offers a wide selection of straights, bends, branches, coupling and installation hardware at a variety of lengths and diameters.

316L Stainless Steel

Stainless steel is a corrosion-resistant, hygienic, low maintenance material with an impressive strength to weight ratio.

Push-Fit

A 10° bevel facilitates easy push-fit connection of sections. Connections are lubed for ease and sealed via double lip seal. No need for on-site welding.

Cold Forming

All components are manufactured using cold forming techniques, which minimize the amount of welding on delivered parts.

SCH 5 Wall Thickness

Minimum lightweight yet durable wall thickness. Components are easy to handle and manipulate during staging and installation.

Double Lip Seal

ACO Pipe is fitted with an EPDM double seal, which provides added security for long term reliability and ease of installation. FPM and NPR seals are available.

Optimum Joint Integrity

Components have a low coefficient of thermal expansion compared to plastics, preventing failures due to temperature fluctuations.

Sag-Proof

Stainless steel piping will not sag over time like PVC, ABS, and HDPE, allowing for less hanging components needed for support.

Stainless Steel

The properties of stainless steel make it a powerful candidate in material selection versus PVC, ABS, and HDPE soil and waste pipework. When total life cycle cost is considered, stainless steel is often the least expensive option, as well.

HygieneFirst

Stainless steel is an excellent material suitable for internal and external use for humans and animals, protecting against harmful bacteria and other contaminants.

ACO designs hygienic drains that promote efficient cleaning, protection against microorganisms, and bacteria and ultimately minimizing financial risk to you.

ACO applies relevant hygienic design principles reserved for food contact surfaces or recommended by NSF/ANSI and EHEDG.

Pickling & Passivation

Superior Finish and Protection

Bending, cutting, and welding during the manufacturing process results in damage to the stainless surface that can lead to corrosion. Pickling and passivation processes restore physical properties of stainless steel.
