Overview of Our Pipe Prefabrication Solution
At FEITING Group, we pride ourselves on delivering a highly engineered and quality-assured Pipe Prefabrication solution tailored to the demands of large-scale petrochemical and energy infrastructure. Our recent involvement in the Ningbo Haiyue Propane Dehydrogenation (PDH) Project is a testament to our capability and precision in providing end-to-end prefabricated piping systems.
Project Background
The PDH project, designed by Sinopec Ningbo Engineering Company, is a cornerstone of China's advanced chemical manufacturing push. With a capacity of 600,000 tons, it requires extensive and highly reliable pipework. FEITING was entrusted to deliver prefabricated piping systems with a maximum caliber of DN2400 — highlighting the scale and complexity involved.
Scope of the Pipe Prefabrication Solution
FEITING’s Pipe Prefabrication solution for this project covered three major piping systems, involving both high and medium-pressure lines. The prefabrication work included complete assemblies of:
Steel pipes cut and beveled to project-specific lengths
Pipe fittings for directional and functional transitions
Welded and slip-on flanges for secure connections
Precision-engineered elbows and tees
High-temperature gaskets for leak-proof operation
All components were fully integrated at FEITING’s modern manufacturing facilities, then thoroughly tested and packaged for direct on-site installation.
Material Selection and Technical Superiority
One of the key strengths of our Pipe Prefabrication solution lies in the use of superior materials capable of withstanding harsh industrial environments:
WP321H / F321H – Excellent resistance to high-temperature corrosion and intergranular cracking.
WP11 / F11 – Chromium-molybdenum alloy steel offering high mechanical strength and oxidation resistance.
WP310S / F310S – Highly austenitic stainless steels ideal for extreme heat applications.
These materials ensure the long-term reliability and performance of the piping systems under severe operating conditions typical in propane dehydrogenation.
Advantages of FEITING’s Pipe Prefabrication Solution
FEITING Group’s pipe prefabrication services are designed to meet international standards and exceed client expectations. Our solution brings the following benefits:
Reduced Construction Time: With up to 90% of welding and assembly completed off-site, clients enjoy significant project acceleration.
Superior Quality Control: All prefabrication processes are performed in a controlled factory environment with certified welding technicians and NDT specialists.
Enhanced Safety: Minimizing on-site fabrication reduces risks associated with open flames and confined spaces.
Material Optimization: Accurate cutting and minimal waste save both resources and cost.
Integrated Process Workflow
Our Pipe Prefabrication solution is supported by a well-structured process that ensures every stage — from material handling to final delivery — aligns with the project schedule. The workflow includes:
Project drawing analysis and isometric preparation
Material procurement and traceability setup
Precision cutting, beveling, and welding
Dimensional inspection and pressure testing
Surface treatment and anti-corrosion coating
Packing, labeling, and shipping logistics
