"ONE" Team The Strengths of JFE Project One

We work together with our customers.

  • We support you in plant construction right from the research and development level.

  • We have experience with various types of fluids (powder, slurry, ultra-high pressure fluids (up to 300MPa), high-viscosity fluids, etc.)

  • We assist in creating PDPs, supporting basic design, and preparing ITB (Invitation to Bid) documents, among other things.

  • We have extensive experience in Southeast Asia, especially in Singapore and Thailand, and we support our customers in their overseas expansion.

Examples of Design Collaboration from the Basic Design Stage
Facility Outline Detail
Polymer Plant Considering equipment during manpower shortages or with tight delivery schedules Examining equipment sizing to equipment placement considerations, creating equipment and instrumentation lists, etc.
We support the creation of client ITBs (Invitation to Bid) and related tasks.
Basic Chemical Plant Examining constructability and cost-effectiveness under challenging site conditions Including layout planning, heavy machinery planning, and transport planning,
we develop and propose feasible plans.
Distillation Equipment Examination of the need for modification and capacity verification of existing equipment due to changes in operating conditions From conducting process simulation to proposing layout planning and on-site construction methods
Intermediate Materials for Electronic Components Batch Reactor Tanks & Fixed Catalyst Continuous Reactor Tanks, Filtration and Recovery of Powdered Catalysts, Distillation Equipment for Reaction Liquids Developing basic designs based on the demonstration data from the customer's laboratory
Solvent Recovery Incorporating a heat pump system into the distillation tower for energy saving measures Proposal of basic design based on our own technology

Heating Furnace
Heating Furnace

We are one of the few domestic engineering companies that possess a specialized unit for heating furnaces

  • We have numerous achievements in various facilities such as heating furnaces, cracking furnaces, hydrogen reformers, and flares.
  • We broadly handle everything from fuel conversion of existing furnaces (including those made by other companies) to energy-saving evaluations.

We conduct feasibility studies for the introduction of HTS (inorganic molten salt-based heat transfer medium).

It can be used at high temperatures (operating temperature range: 300-550°C).

We have extensive experience with facilities subject to the High Pressure Gas Safety Act

  • Capable of handling self-certified construction of piping.
  • Seismic strength calculations using SEISMIT-TW, SP, etc. (Level 1, 2).

Spirelf (Dirt Preventer)

  • Prevents dirt inside the tubes of multi-tube heat exchangers (contact + turbulent effect).
  • Developed by the former ELF company in France.
  • A spring-like metal device is installed inside the tube and fixed at both ends of the tube for use.

Dense Smoke and Hot Air Live Fire Training Device

  • A hot training facility where firefighters experience dense smoke and hot air.
  • We have also developed a VR system for a safer experience.
