Characteristics

Can only be used for buried pipe lines if the tube appears above ground, the visible section must be protected by a pipe sleeve (protection against ultraviolet radiation) It is highly chemical resistant, ductile, shock resistant, lightweight and less expensive than copper or steel.

Hydrostatic mechanical water resistance test pressure: 10 bars

HDPE can only carry LPG in the gaseous phase. HDPE requires covered storage (see sell-by dates). It comes in rings or coils depending on diameter.

HDPE is connected in various ways: Either using electro weldable couplings Or electro weldable T fittings

Characteristics

Use of HDPE is prohibited:

for above ground pipe lines for ventilation spaces

for passage under vehicle thoroughfares

For passage under vehicle thoroughfares, they must be protected by reinforced concrete or steel pipe sleeves.
