YJTMC is leading manufacturer in the fabrication design and manufacture of Primary Quench Exchanger for petrochemical industry. Since 2000, YJTMC has been researching and developing machine welding processes and equipment for the fabrication of various special types of heat exchangers.
In 2003, we successfully completed our first project for PQE fabrication using our own developed welding process and Jig-fixtures at DHIC's Changwon shop, based on the results of our R&D and innovative spirit. Since then, we have been the main contractor for PQEs over 20 ethylene furnace projects at YJTMC's Haman shop, demonstrating our expertise in the field. With our experience in the design and manufacturing of special equipment, YJTMC is fully equipped to provide various types of pressure vessels and heat exchangers, including PQEs.
