Oil & Gas

Petrochemical plants run under high temperature, high pressure, aggressive corrosion and flammable atmospheres — a leaking flange bolt can trigger a major incident, so fastener requirements are severe. JIALI supplies 316 / 316L, 2205 duplex and corrosion-resistant alloy bolts with Dacromet and PTFE coatings to ASME and ASTM specifications, meeting the reliability required of Hong Kong petrochemical plant corrosion-resistant fasteners, with material certificates and third-party testing supported.

Typical Applications

  • Reactor & heat-exchanger flanges
  • Pipeline flanges & valve assembly
  • Storage tanks & column platforms
  • Pump & compressor base fixing
  • High-temperature steam lines
  • Coastal refinery corrosion zones
