Indonesia Hydrometallurgical Project

1. Project Overview

• The project is a large-scale nickel hydrometallurgical processing project in Indonesia, involving laterite nickel ore processing and supporting pipeline infrastructure.

• The demanding operating environment required pipeline systems with high strength, corrosion resistance, reliable long-term performance and efficient installation, particularly for large-diameter process applications.

2. Donghong Solution

• Large-Diameter SRTP Mining Pipeline

• Donghong supplied DN1000 mm Steel Wire Reinforced Polyethylene (SRTP) mining pipes for the project's hydrometallurgical process pipeline system.

• The composite structure combines the high mechanical strength of steel wire reinforcement with the corrosion resistance and lightweight characteristics of polyethylene, providing a cost-effective alternative to conventional metal piping for demanding mining applications.

• The large-diameter solution also reduces the number of pipeline runs required for high-volume fluid transportation, supporting efficient system design and installation.
