ACO PIPE® System

Basic characteristic

The ACO PIPE® push-fit pipe system made from stainless steel (both AISI 304 and 316) provides a modern alternative to plastic and zinc-coated pipes for water drainage and vacuum systems. The ACO Pipe® system has a proven high level of resistance against aggressive media. A diverse and versatile range of fittings are available along with ACO drainage channels and scuppers to develop a complete tailored pipe system solution. Simple assembly and installation with reduced installation time and an exceptional level of corrosion resistance provide a cost efficient solution compared to conventional flanged black steel systems.

The ACO PIPE® push-fit pipe system is recognised and certified by all leading maritime classification societies.


Introduction

The ACO PIPE® stainless steel socketed push-fit pipe systems offer a modern alternative to plastic and galvanised pipes for water drainage and vacuum applications. The ACO PIPE® system is highly resistant to aggressive media and offers simple assembly enabling greater flexibility in its application and installation. Installations are considerably lighter than with conventional black steel systems and have a high fire safety rating and are highly resistant to corrosion. By request AISI 317 options are available to meet particular corrosion associated with increased levels of chlorine. For more details on these types of installation please contact us.

All these attributes offer the user a system that represents not only excellent value but also high performance. The ACO PIPE® push-fit pipe system is recognised and certified by all leading maritime classification societies.


Material Properties

The ACO PIPE® stainless steel socketed pipe systems are made of austenitic stainless steel.


Expansion Coefficient

Due to its low expansion coefficient, ACO PIPE® stainless steel products do not require any special measurements to be taken for installation in standard drainage and vacuum applications. The expansion coefficients of different materials are specified below. The values refer to linear expandability in mm per 1 m pipe length at a temperature of approx. 60 °C.

ACO PIPE Sockets

The ACO PIPE® sockets are designed as two-chamber components for stable and durable joint fitting in the ACO PIPE®system of pipes and fittings.


ACO PIPE® Seals

The socket chamber contains a special factory-fitted ACO seal. The unique engineering design of the seal ensures that the end of the ACO PIPE fits tightly, not only onto the seal in the chamber, but also around the diameter of the inserted pipe. This slip-proof and double-seal function of the ACO seal guarantees long a lasting and leak-proof installation. Standard ACO PIPE® sockets are provided with EPDM seals and may be installed in systems exposed to temperature ranges from –50 °C to +130 °C.
