Overview

We are pleased to announce the full successful commissioning and first start-up completion of our customized valve solution for a leading steel manufacturer’s Air Separation Unit (ASU) project in Korea. This overseas landmark project marks another solid breakthrough in our global market layout and industrial gas industry application capability, verifying our reliable engineering strength and overseas project delivery experience.

Project Background & SuppliedProduct Range

Air separation unit is the core facility for stable gas supply in modern steel production, requiring long-term continuous, high-precision and zero-failure operation. The Korean steel industry holds extremely strict standards for valve performance, material adaptability and sealing reliability under complex working conditions.

For this high-standard ASU project, we provided tailored valve solutions covering the core working scenarios of the entire air separation system, including: Cryogenic globe valves inside coldbox and outside coldbox, and Ambient globe valves. The matched dual product lineup perfectly covers low-temperature cold box environments and conventional normal-temperature pipeline systems, meeting the full-cycle fluid control demands of ASU production.

Technical Strength & Project Advantages

This ASU plant not only undertakes conventional air separation tasks, but also produces high-value rare gases (Ne, He, Kr, Xe), which demand ultra-precise flow control and extreme sealing stability under cryogenic temperatures. Such rigorous operating conditions put forward ultra-high requirements for valve precision, temperature resistance and operational stability.

Our professional globe valve series deliver outstanding performance for this challenging project. The cryogenic globe valves are specially optimized for cold box internal and external installation environments, effectively adapting to extreme low-temperature working conditions, avoiding temperature deformation and control deviation, and ensuring stable and accurate fluid regulation for cryogenic gas and rare gas production. The ambient globe valves maintain stable, precise and consistent flow control for conventional normal-temperature pipelines, supporting the continuous and efficient operation of the entire ASU system.

All supplied valves are engineered in full compliance with international industrial standards and project-specific specifications. The entire unit achieved zero valve-related faults during the first start-up, completely avoiding common industry problems such as unstable flow regulation and medium leakage, and fully satisfying the stringent technical requirements of rare gas purification and steel industrial gas supply systems.

Project Value & Strategic Significance

The successful stable operation of this Korean ASU project strongly verifies our professional R&D, manufacturing and customized solution capabilities in the steel and industrial gas sectors. This in-depth cooperation fully demonstrates the excellent adaptability and reliability of our ambient and cryogenic globe valves in high-end air separation and rare gas production scenarios.

As an important overseas benchmark project, it further expands our market influence in East Asia’s industrial manufacturing field, accumulates rich practical experience for subsequent overseas ASU and steel industry projects, and lays a solid foundation for the company’s continuous deepening of global market layout.

Conclusion & Service Commitment

Adhering to the concept of quality-oriented and customer-centric, we will continue to focus on the R&D and optimization of industrial valve products for high-standard industrial scenarios such as air separation, petrochemical and metallurgy. We will provide global customers with one-stop, customized and reliable fluid control system solutions and full-cycle project service support.
