Sichuan-Tibet Railway (Ya'an to Linzhi section) project

Products：Ductile Iron Pipe, High-Strength Seamless Steel Pipe, Hot Rolled Steel Coil

Quantity: 5300 tons

Project location: The route spans Sichuan Province and the Tibet Autonomous Region. It starts in Ya'an, Sichuan, and goes west through Tianquan, Luding, Kangding, Yajiang, and Batang before crossing the Jinsha River into Tibet. It then passes through Gongjue, Changdu, and Bomi before reaching Linzhi.

Date: 2021.12

Project Story

I. Project Overview: A World-Class Construction Challenge

Project Name: Ya'an-Linzhi Section of the Sichuan-Tibet Railway

Engineering Characteristics: The line traverses the Hengduan Mountains, passing through high-intensity earthquake zones, high-temperature tunnels, and areas prone to landslides and debris flows.

Material Standards: Due to the high-altitude location of the construction site, materials must possess excellent low-temperature toughness, fatigue strength, and superior corrosion resistance.

II. Shandong Runhai Steel's Material Supply Matrix

Addressing the complex and variable working conditions of the Sichuan-Tibet Railway, Shandong Runhai Steel provides targeted product solutions: ductile iron pipes (possessing the essence of iron and the performance of steel, with high seismic resistance and excellent ductility), high-strength seamless pipes (precise heat treatment process ensures the material does not fracture in extremely cold environments), and hot-rolled coils (uniform composition, excellent weldability, and strong impact load resistance).

III. Overcoming Challenges: The Core Competitiveness of Products

1. Withstanding Extreme Cold: The toughness of high-strength seamless pipes; 2. Withstanding Strong Earthquakes: The ductility advantage of ductile iron pipes; 3. Efficient Construction: The weldability of hot-rolled coils.

IV. Cooperation Value and Strategic Significance

1. Ensuring Infrastructure Safety: Shandong Runhai's products not only provide physical support but have also passed multiple safety verifications by national-level testing institutions, ensuring the long-term success of this monumental project. 2. Implementing National Strategy: Participation in the "mega-project" of the Sichuan-Tibet Railway signifies that Shandong Runhai Steel possesses top-tier R&D and supply capabilities in serving key national infrastructure construction.

3. High-Altitude Logistics Fulfillment: Facing the challenges of treacherous routes and inconvenient logistics to Tibet, the company overcame high-altitude transportation difficulties through specialized scheduling, ensuring the timely and high-quality arrival of materials.

From the Chengdu Plain to the snowy plateau, Shandong Runhai Steel's products are accompanying the rails of the Sichuan-Tibet Railway, traversing treacherous terrain and connecting the future. Every pipe and every steel plate embodies Runhai's dedication to quality, contributing indelible wisdom and strength to building a "green and safe railway."
