GRP / GRE
GRE MATERIAL KOREAN BRAND
GRE(Glass-fiber Reinforced Epoxy) pipe is used in oil fields to increase workable pressure.
Epoxy resin typically allows for higher service temperatures than polyester resins, ranging up to 110℃. GRE pipe have superior properties to GRP(Glass-fiber Reinforced Polyester) pipe.
GRP MATERIAL KOREA TOP BRAND
GRP(Glass-fiber Reinforced Plastic) pipe resists a wide range of chemicals. The chemical resistance of GRP pipe depends primarily on the particular resin matrix material used.
The temperature resistance and workable pressure of GRP pipe also depends largely on the resin matrix.
Method
FILAMENT WINDING
GRP(Glass-fiber Reinforced Polyester) pipe is manufactured
by a self-developed winding machine. The mandrel
installed with the machine is wound with E/C-glass and
the Impregnated glass-fiber with resin at an angle of 54
degrees. In GRP standards, DN is GRP pipe’s inner diameter
and the mandrel’s outer diameter. The curing,
de-molding and machining progress is then performed.
