Tajikistan Hydropower Station Project

A Testament to Excellence in Large-Diameter Steel Pipe Supply

Project Overview

Project Name: Hydropower Station Project

Location: Tajikistan

Scope: Supply of DN2300 (OD2337×14MM) steel pipes for high-pressure water conveyance in a critical hydropower infrastructure project.

Challenge: Meeting Stringent Standards for Large-Scale Hydropower Infrastructure

The Tajik Hydropower Station project demanded steel pipes capable of withstanding extreme water pressure while ensuring long-term durability in a demanding environment. The client required:

Large-diameter pipes (DN2300) with precise dimensions (OD2337×14MM).

Compliance with EN10025-2/EN10217 standards, using S235J2 material for structural integrity.

Zero tolerance for wall thickness deviations (upward bias only) to guarantee safety under high-pressure conditions.

Advanced corrosion protection: Solvent-free epoxy resin coating internally and 3LPE (3-Layer Polyethylene) externally.

Rigorous quality validation, including third-party pressure testing and full documentation review.

Our Solution: Precision, Expertise, and Uncompromising Quality

Leveraging our expertise in large-diameter pipe manufacturing, we delivered a tailored solution that exceeded expectations:

1. Customized Pipe Production

Produced SSAW/Spool pipes with an outer diameter of 2.3 meters (scalable up to 4 meters), meeting the client’s unique specifications.

Utilized S235J2 steel per EN10217, ensuring optimal strength and weldability for hydropower applications.

Maintained strict wall thickness control (upward bias only) to eliminate weak points and guarantee long-term performance.

2. Advanced Corrosion Resistance

Applied solvent-free epoxy resin internally for chemical resistance and smooth water flow.

Coated externally with 3LPE for superior protection against environmental corrosion, extending pipe lifespan.

3. Comprehensive Quality Assurance

Conducted high-pressure water testing to validate performance under simulated operational conditions.

Provided full technical documentation for client review, including material certificates, testing reports, and production traceability.

Passed third-party inspections with flying colors, ensuring compliance with international standards.

Outcome: Client Satisfaction and Industry Recognition

l 100% compliance with the client’s technical and safety requirements.

l Seamless integration into the hydropower station’s water conveyance system, with zero defects reported during installation.

l Strengthened client trust, leading to discussions for future collaborations on similar large-scale infrastructure projects.

l Enhanced reputation as a global leader in supplying high-specification pipes for energy sector applications.
