Advantages of GREDurable and Corrosion ResistantInternal and external surfaces resistant to a wide variety of chemicals, crude oil, residues, injection water and bacteria in aggressive and caustic environments.

LightweightA quarter to an eighth of the weight of comparable steel pipe; easy to install without the requirement of heavy equipment or machinery; no welding; no X ray; etc

Cost-effectiveSmooth internal surfaces reduce friction and maintain flow volumes, thus allowing for downsizing of piping system or decreased pumping costs and optimal operating flows

Low Life Cycle CostGRE pipe has lower life cycle cost compared with steel pipe. Practically no maintenance required after installation and therefore no operational downtime.

Hanwei Integrated GRE Piping SystemsComplete range of GRE piping systems with different diameters, joint systems and pressure ratings to suit different applications, including different choices of joint systems. In all cases superior performance and cost to steel pipe.

Common Steel PipeHanwei GRE Pipe

Severe corrosion after steel pipe put in service for some time under highly corrosive application

Epoxy matrix, which can meet the stringent requirement for delivery of highly corrosive media



Long service life

20-30 years (can go up to 50 years)

Short service life

5-10 years (No Cathodic Protection or Corrosion Inhibitor)


Light Weight• Low transportation and

installation cost.• Low thermal conductivity• Good electrical and magnetic

insulation properties• Not affected by complex

geographical, conductive or static electricity conditions

• Environmental protection• Low energy consumption during

field use and operating/production

• No significant maintenance costs

Heavy weight• Higher transportation and

installation cost.• High thermal conductivity• No electrical and magnetic

insulation properties• Conducts electricity• Not conducive to application in

areas with dense electrical transmission lines and telecommunication lines.

• High energy consumption during field use and production

• Ongoing maintenance costs




Low operation cost

• Very smooth inner wall which reduces paraffin and scale build up

• Very low surface friction increases efficiency of flow rates and volumes

Low maintenance cost. Requires minimal or no maintenance.

High operation cost

• Rough inner surface• Easy to form scale and

paraffin deposits• High surface friction

results in loss of working pressure and flow rates.

High ongoing maintenance costs and operational closures. Requires corrosion protection coatings, cathodic protection and corrosion monitoring.
