Precision Prefabrication Supports Cutting-Edge CATOFIN Dehydrogenation Technology
Project Background
FEITING Group proudly announces its successful delivery of Lummus PDH Pipe Prefabrication solutions for the Ningbo Haiyue Propane and C4 Utilization of Propane Dehydrogenation Project. This strategic project, developed by Ningbo Haiyue New Material Co., Ltd. and designed by Sinopec Ningbo Engineering Company, employs advanced CATOFIN technology to convert propane into propylene with outstanding efficiency.
About CATOFIN PDH Technology
The CATOFIN process is a fixed-bed dehydrogenation technology used worldwide to produce high-purity propylene from propane. Its core advantage lies in its reliable performance, low energy consumption, and high selectivity. Operating under optimal temperature and pressure conditions, CATOFIN reactors deliver superior conversion rates and high propylene yields—making it a favored option for PDH (Propane Dehydrogenation) projects globally.
FEITING Group’s Lummus PDH Pipe Prefabrication services were developed in full compliance with the design demands of the CATOFIN process, ensuring temperature resilience, pressure integrity, and operational reliability.

Core Advantages of FEITING's Lummus PDH Pipe Prefabrication
FEITING Group’s Lummus PDH Pipe Prefabrication approach is built on a foundation of engineering rigor, industrial insight, and a commitment to client success. Our prefabrication services offer a range of benefits that are particularly vital for high-performance PDH systems:
High Precision Fabrication: Our advanced CNC and robotic welding facilities ensure unmatched dimensional accuracy and weld quality.
Material Excellence: Using corrosion-resistant and high-temperature alloys such as WP321H and WP11 ensures long-term durability in severe operating environments.
Reduced On-Site Labor: Our pre-tested, pre-assembled modules minimize installation complexity and field welding, which accelerates project timelines.
Energy Efficiency: Waste heat recovery components are designed to enhance energy utilization across the PDH system, aligning with green engineering principles.
Compliance with International Codes: All prefabrication follows ASME, ISO, and customer-specific standards to meet safety and reliability benchmarks.
Design Collaboration and Execution
Working closely with Sinopec Ningbo Engineering Company, FEITING’s technical team ensured that all Lummus PDH Pipe Prefabrication drawings and material specifications were fully aligned with CATOFIN process requirements. The large diameter (DN2200) of the system introduced engineering challenges, especially in ensuring weld integrity and thermal expansion control, which were successfully overcome through detailed FEA simulations and stringent QC protocols.
Sustainability and Innovation
Our prefabricated piping systems integrate sustainability at every stage—from design to delivery. The waste heat mixer unit itself reflects an energy-conscious philosophy, reusing excess heat to reduce fuel consumption and carbon emissions. FEITING Group also implements green manufacturing practices, such as low-waste cutting, recycling of metal offcuts, and solvent-free coatings.
Customer Satisfaction
The prefabricated piping set has been fully delivered to the Ningbo Haiyue construction site and successfully passed dimensional checks and pressure testing. The client has recognized FEITING Group for its fast response, engineering support, and outstanding execution throughout the project lifecycle.
