Chemical resistance
NOTICE!
Damage to material due to aggressive chemicals
Aggressive chemicals, especially those containing solvents,
may cause material damage and leaks. This may lead to
water damage.
– Prevent contact between the system components and
aggressive chemicals.
NOTICE!
Material damage due to impermissible leakage detection
agents
Impermissible leakage detection agents may cause material
damage and leaks. This may lead to water damage.
– Use only leakage detection agents approved by the
manufacturer for use on PPSU material.
– Observe the manufacturer's notes on processing.
Protect the system components against excessively high concentra‐
tions of chloride generated by both the medium or in the area around
the area of use. An excessive chloride concentration can lead to corro‐
sion in stainless steel systems.
The chloride concentration in the medium must not exceed a maximum
value of 250 mg/l.
The following rules apply for avoiding external contact with materials
containing chloride:
n
Insulating materials must not have a water-soluble chloride ion con‐
tent by weight that exceeds 0.05 %.
n
The sound insulating inlays on the pipe clamps must not contain
leachable chloride.
n
Stainless steel components must not come into contact with building
materials or mortar containing chloride.
If external corrosion protection is required, observe the general rules of
engineering, see
