Understanding the Role of Pressure Vessels in Hydrogen Energy
A Pressure vessel is a container designed to hold gases or liquids at a pressure substantially different from the ambient pressure. In hydrogen energy and chemical industries, pressure vessels are core components for processes involving high temperature and high pressure. They must be constructed from materials that provide superior mechanical strength, corrosion resistance, and thermal stability.
FEITING Group is a specialized supplier of high-grade pressure vessel piping systems, delivering prefabricated assemblies tailored to the world’s most demanding projects. One such example is our recent supply for the 900,000 tons/year Propane Dehydrogenation (PDH) unit — a critical part of the hydrogen energy development infrastructure.
Project Overview
Designed by Qilu Petrochemical Design Institute, the PDH unit is a major pillar of the New Materials and Hydrogen Energy Comprehensive Utilization Project. This facility transforms propane into propylene and supports downstream hydrogen energy applications. To meet its exacting technical standards, FEITING Group was entrusted to manufacture and deliver piping systems integrated with pressure vessel functionality, ensuring safe and efficient media transport under extreme conditions.
Technical Specifications and Product Highlights
The prefabricated solution from FEITING included three primary piping systems capable of handling elevated temperatures and pressures. The pipeline diameter reached a maximum of DN2700, showcasing FEITING’s fabrication scale and engineering capability. The prefabricated components included:
High-strength steel pipes
Welded and slip-on flanges
Precision reducers and elbows
High-performance sealing gaskets
These parts were prefabricated under strict industrial protocols, ensuring every component aligned with the high-performance standards required for pressure vessel systems.
Advanced Material Applications
One of the core success factors of this project was the use of specialty alloys specifically designed for high-pressure, high-temperature environments:
WP321H / F321H: Austenitic stainless steel with titanium stabilization for high-temperature creep resistance.
WP22 / F22: Chromium-molybdenum steel ideal for elevated pressure and thermal stress environments in pressure vessel assemblies.
WP310S / F310S: Heat-resistant stainless steel known for excellent oxidation and scaling resistance at temperatures exceeding 1000°C.
All material grades were fully traceable and matched to quality inspection records to guarantee long-term durability and compliance.
Benefits of FEITING’s Pressure Vessel Fabrication Approach
FEITING’s prefabrication and delivery model for pressure vessel pipeline systems provides the following critical advantages:
Reduced Site Work: Prefabrication minimizes the need for complex on-site welding and assembly.
Improved Safety: Factory fabrication lowers the risk of high-temperature on-site processes.
High Dimensional Accuracy: CNC-controlled manufacturing ensures tight tolerances.
Enhanced Quality Control: All components undergo NDT, pressure testing, and surface inspection before dispatch.
These advantages have made FEITING a preferred partner for pressure-intensive infrastructure projects across the energy and chemical sectors.
