Coking Heat Exchanger Power Plant Shell And Tube Condenser Spiral Plate

Heat Exchanger, Shell‑and‑Tube & Spiral Plate Heat Exchanger, Condenser, Cooler, Heat Transfer Equipment for Coking, Power Plant, Petro‑Chemical, Custom Pressure‑bearing Heat Exchange Unit

All heat exchangers are strictly designed according to GB150, ASME BPVC Section VIII‑1, IBR, PED, JIS and KS codes, complying with NB/T 47004 for spiral‑plate heat exchangers. Fabrication follows validated WPS & PQR welding procedures, with integral post‑weld stress‑relief heat‑treatment for heavy‑wall shells and critical weld joints. Every finished unit undergoes 100% full‑range UT, RT, MT, PT non‑destructive testing, plus hydro‑static pressure test at 1.5 times of design pressure and tightness inspection before shipment. Complete material test certificates(MTC), full NDT inspection reports, thermal‑mechanical calculation sheets and full export‑oriented technical documentation are provided for global project acceptance. Our heat‑exchange equipment has been exported to over 30 countries across Southeast Asia, Central Asia, Middle East, Japan and South Korea, widely adopted in new‑project construction, energy‑saving revamping and heat‑exchanger replacement works.
