As an industry leader in high-end industrial pipeline manufacturing, FEITING Group is proud to announce the successful delivery of precision Pipe Prefabrication Services for the New Materials and Hydrogen Energy Comprehensive Utilization Project, specifically for the 900,000 tons/year Propane Dehydrogenation (PDH) Unit. This project represents a critical step in China’s transition to sustainable chemical processing and highlights our strength in providing comprehensive Pipe Prefabrication Services for high-temperature and high-pressure applications.

Project Overview

Design Unit: Qilu Petrochemical Design Institute

Project Name: New Materials and Hydrogen Energy Comprehensive Utilization Project

Unit: 900,000 tons/year Propane Dehydrogenation Unit (Reactor High-Temperature Piping)

Product Name: Three Major Piping Systems

Product Specifications: Maximum Diameter DN2700

Product Materials: WP321H, F321H, WP22, F22, WP310S, F310S

FEITING Group’s scope of Pipe Prefabrication Services includes critical components such as:

√ High-performance flanges

√ Precision-engineered elbows

√ Seamless and welded steel pipes

√ High-temperature-resistant gaskets

All components were prefabricated in our state-of-the-art factory under strict process control and quality assurance protocols.

What Sets FEITING’s Services Apart?

Our Pipe Prefabrication Services offer unparalleled advantages in quality, speed, and cost efficiency. For the reactor pipelines in the PDH unit, we applied high-temperature-resistant materials capable of withstanding the extreme conditions of dehydrogenation reactions. Each prefabricated part was manufactured according to the specifications of Qilu Petrochemical Design Institute, ensuring exact dimensions, tolerance controls, and flawless weld integrity.

Key features of our Pipe Prefabrication Services include:

High Precision: CNC-assisted cutting, beveling, and welding ensure component compatibility and dimensional accuracy.

Advanced Materials: Alloys like WP321H and F321H provide excellent creep resistance and oxidation stability at high temperatures.

Time-Saving: Offsite prefabrication significantly reduces construction time at the job site.

Improved Safety: Less hot work on-site leads to fewer safety hazards.

Cost Control: Reduced manpower, material waste, and downtime.

Commitment to Project Excellence

The reactor pipelines are the core of the PDH process, transporting high-temperature hydrocarbons with stability and safety. Our Pipe Prefabrication Services ensured rapid and reliable pipeline delivery for this crucial process section.

FEITING Group applied full-cycle QA/QC, including:

√ Radiographic testing (RT)

√ Dye penetrant testing (PT)

√ Ultrasonic testing (UT)

√ Dimensional inspections and PMI (Positive Material Identification)

From material procurement to prefabrication, inspection, packaging, and delivery, every phase of our Pipe Prefabrication Services was executed to exceed project specifications.
