2.4 Information for use2.4.1 Corrosion

The corrosion resistance against seawater is due to the phenomenonthat a CuNiFe alloy forms a thin protective layer on the surface if itcomes into contact with clean seawater.

The wrought iron alloy CuNiFe 1.6 Mn is very resistant to corrosion afterthe protective coating has formed. Especially with saltwater and otheraggressive waters such as e.g. brackish and bilge water and their sur‐rounding area.

For notes on corrosion of metals in saltwater and marine atmosphere,see the applicable regulations, Ä ‘Regulations from section: Corrosion’on page 6.

3 Handling

3.1 Transport

Observe the following when transporting pipes:

n Do not pull the pipes over the sill. The surface could be damaged.n Secure pipes during transportation. Pipes may become bent due to

shifting.n Do not damage the protective caps on the pipe ends and do not

remove them until immediately before mounting. Damaged pipeends may not be pressed.

In addition, observe the instructions provided by the pipemanufacturer.

3.2 StorageObserve the following when storing pipes and press connectors:

n Store components in a clean and dry place.n Do not store the components directly on the floor.n Provide at least three points of support for the storage of pipes.n Where possible, store different sizes separately.

Store small sizes on top of larger sizes if separate storage is not pos‐sible.

n Store pipes of different materials separately to prevent contact cor‐rosion.

In addition, observe the instructions provided by the pipemanufacturer.

3.3 Assembly information3.3.1 Mounting instructions

System components may, in some cases, become damaged throughtransportation and storage.

n Check all parts.n Replace damaged components.

Checking system components

Handling

Seapress 14

n Do not repair damaged components.n Contaminated components may not be installed.

3.3.2 Potential equalisation

DANGER! Danger due to electrical currentAn electric shock can lead to burns and serious injury andeven death.

Because all metallic piping systems conduct electricity,unintentional contact with a live part can lead to the wholepiping system and components connected to it (e. g. radi‐ators) becoming energised.

n Only allow electrical work to be carried out by qualifiedelectricians.

n Always integrate the metal piping system into thepotential equalisation.

It is the fitter of the electrical system who is responsiblefor ensuring that the potential equalisation is tested andsecured.

3.3.3 Permitted exchange of sealing elements

Important instructionWith their material-specific qualities, sealing elements inpress connectors are adapted for use with the corre‐sponding media and/or the areas of use of the piping sys‐tems and are generally only certified for them.

The exchange of a sealing element is generally permitted.The sealing element must be exchanged for a designatedspare part for the intended application Ä Chapter 2.3.4‘Sealing elements’ on page 11. The use of other sealingelements is not permitted.

Exchanging a sealing element is permitted in the following situations:

n if the sealing element in the press connector is obviously damagedand should be exchanged for a Viega spare sealing element made ofthe same material

n if an EPDM sealing element should be exchanged for an FKM sealingelement (due to higher thermal resistance on ships)
