Aurashu Supports Indonesia National Energy Infrastructure Project with Coated Composite Steel Pipes

Summary

Aurashu provided coated composite steel pipes for Indonesia’s national energy project, ensuring reliable transmission, strong corrosion resistance, and long-lasting, efficient system performance.

Project Background
This project, located in a key energy region of Indonesia, involves the expansion of a gas-fired combined-cycle power plant and associated transmission and distribution pipelines. Given the tropical coastal climate and the high durability requirements of the pipeline system, coated composite steel pipe was selected for critical sections of the network. As the supplier and partner, Aurashu was responsible for providing the required pipeline system and supporting services to ensure the project's on-time, quality, and production schedule.
Project Challenges:
   ●  Harsh environmental conditions: High humidity, severe salt spray corrosion, and fluctuating ground conditions in tropical coastal areas place extremely high demands on pipeline materials.
   ●  High reliability and long life requirements: Energy transmission networks must operate continuously with minimal maintenance; pipeline failures or leaks could cause significant disruptions.
   ●  Complex specifications and logistics: The project required large-diameter steel pipes, specialized coating systems (e.g., 3LPE, FBE), long pipe strings, extensive prefabrication, and logistical coordination across remote sites.
   ●  Integration with existing infrastructure: The coated composite pipelines needed to be compatible with the existing pipe network, joints, welding standards, and corrosion protection systems, requiring precise engineering design and collaboration with local EPC contractors.
Solution: Coated Composite Steel Pipe Systems & Support Services
To meet these challenges, Aurashu offers comprehensive piping solutions:
   ●  High-Quality Steel Pipe Options: Pipe manufactured to API-5L X52/X60 or equivalent standards is suitable for high-voltage, high-temperature transmission lines.
   ●  Advanced Coating Systems: Multi-layer polyethylene (3LPE) or fusion-bonded epoxy (FBE) external coatings are designed to resist corrosion, saltwater attack, and mechanical damage; internal coatings or concrete linings are available upon request.
   ●  Prefabrication and Logistics Management: Pipe is supplied in pre-welded sections, factory-applied protective coatings, and numbered sections, with coordinated transportation to Indonesia. Local installation support is also provided.
   ● Lifecycle Support and Monitoring Services: Aurashu assists with implementing coating integrity monitoring, corrosion inspection programs, and maintenance guidelines to help reduce lifecycle costs and downtime.
Technical Highlights
   ●  Pipeline Specifications: For example, API-5L X52 steel pipe, 900 mm diameter, 12 mm wall thickness, coated with a three-layer polyethylene (3LPE) coating.
   ●  Coating System: Three layers of polyethylene (PE) with a total thickness of ≥ 3 mm, suitable for buried and coastal environments, with full adhesion and holiday testing.
   ●  Designed Service Life: Over 20 years with minimal maintenance, even in tropical coastal conditions.
   ●  Logistics and Installation: Multimodal transport (sea and road), factory-prefabricated segments, on-site supervision, and coating repair guidance.
   ●  Monitoring and Support: Coating integrity tracking, corrosion scanning, and operational asset health reviews.
Project Significance
This energy infrastructure project is a milestone in Indonesia's national energy strategy, aimed at increasing power generation and transmission capacity and improving reliability. Aurashu's coated composite steel pipe solutions help reduce pipeline failures, lower maintenance intervention costs, and improve asset lifecycle performance. For Aurashu, this project further demonstrates our capabilities beyond HVAC systems, extending to large-scale energy infrastructure supply and technical services. It also underscores our commitment to delivering high-performance, durable, and sustainable engineered systems in a challenging international environment.
