2-4 Superiority of GRE pipe

16

Chemical Resistance

- No damage from Oil, Seawater, Sewage, Chemicals,Exhaust gas

- Lower maintenance cost Longer replacement period than steel

Dimensional Stability

Thermal expansion in the circumferential & axial directions during the production sets off dimensional deformation.

Light Weight

- ¼ of a weight of steel pipe

- Easier installation & handling

Low Friction Loss

- Smoother surface with 43% lower friction loss than steel pipe

- Superior fluid flow

- Hazen Williams Factor 150

Wide Range of Production

Diameters (25A~ 900A) with major Classes(up to 25 bar)

1350A under tests for approval, Feb, 2021

Low Installation Cost

- Cheaper and easier joint method than Welding one

- Lower transportation cost

GRP / GRE Production

2-4 Superiority of GRE Pipe

Low maintenance cost for its semi permanent life cycle

Superior properties than other pipe materials

Used in oil field and marine industry, design pressure up to 25 bar.

Higher temperature allowance up to 108℃.

2-4 Superiority of GRE Pipe

* Better mechanical and chemical properties compared to GRP and GRV pipes

* More resistant to corrosion, mainly used in the petrochemical industry’s processing lines and oil and gas lines

2-5 Joint Methods

BUTT & WRAP

Laminating method on the pipe ends meet each other.

Highly adoptable for the installation in a confined room, for its easier

adjustment workability in the field adjustment work.

i.e. SOx scrubber line

DOUBLE O-RING EXPANSION COUPLING

Double O-rings and Lock-key are inserted in the expansion adaptor.

Suitable for where it requires resistance from external pressure.

i.e. Ballast Line

FLANGES

Same to steel pipe’s flange joint type. Applicable to ANSI. JIS, DIN standards.

Can be connected to different pipes materials.

BELL & SPIGOT

Applicable where it requires precision, quick, resistance force against inner

pressure.
