Description
GeoFusion socket heat fusion 󶈵ttings are intended and
recommended for use in open or closed loop, ground
source heat pump systems installed with IPS-OD, HDPE
pipe manufactured to a minimum pressure rating of
SDR11 or Schedule 40.
This product speci󶈵cation designates the requirements for
GeoFusion high density polyethylene (HDPE) socket heat
fusion 󶈵ttings to be used as connections for Iron Pipe Size
Outside Diameter (IPS-OD) controlled HDPE pipe in ¾",
1", 1¼", 1½", and 2" sizes.
Materials
GeoFusion HDPE socket heat fusion 󶈵ttings are
manufactured from a bimodal polyethylene resin
PE4710 with a cell classi󶈵cation, PE345564C per ASTM
D-3350. This high performance resin exhibits enhanced
performance properties including superior Slow Crack
Growth (SCG) resistance plus improved tensile strength
and modulus.
GeoFusion socket fusion by metallic adapter 󶈵ttings are
manufactured using machined components of brass alloy
B360 per ASTM B-16 that are inserted into the molded
polymer 󶈵tting body and attached by a stainless steel
press ring.
Certi󶈵cations
■ ASTM D 2683
■ NSF 358-1
UV Resistance:
Viega GeoFusion 󶈵ttings are produced using a minimum of
2% carbon black, a material used to protect PE products
from the e󶈴ects of UV radiation. Viega GeFusion 󶈵ttings
can be used in exposed, above ground applications for
inde󶈵nite periods of time and do not require protection
from UV exposure during shipping, handling, storage,
installation or use.
