FRP Pressure Vessels

FRP pressure vessels (High-Pressure Vessels) are filament-wound composite tanks designed to withstand internal pressure while remaining corrosion-proof. Unlike atmospheric tanks, these vessels are engineered to ASME or European codes for pressures typically up to 10 bar. The polar winding technique (winding shell and ends in one piece) yields a seamless, stronger vessel.

Key Features

  • Polar Winding Construction: One-piece filament-wound shells and ends for uniform strength
  • Pressure Rated: Designed for pressures up to 10 bar (gauge) or more as required
  • Standards Compliant: Fabricated per ASME Section X (or other codes) with options for CE marking
  • Leak Detection: FRP vessels inherently non-corroding; optional instrumentation for pressure monitoring

Benefits

  • Economical High-Pressure FRP: Thicker laminates replace expensive metal in corrosive pressure duties, reducing cost
  • Lightweight Strength: Lower weight than equivalent steel or GRP vessels
  • Durable: Long life even under cyclic pressure conditions without corrosion fatigue

Applications

  • Process Industry: Pressurized scrubbers, gas holders, high-pressure chemical reactors
  • Oil & Gas: Autoclave vessels for injection/dissolution in petrochemical processes

Technical Specifications

  • Design Pressure: Up to 10 bar(g); higher pressure available on request
  • Construction: Filament-wound FRP using vinyl ester or epoxy resin
  • Compliance: Meets ASME RTP-1 or Section X standards; CE marking optional
  • Volume: Typically up to several hundred cubic meters

Unique Selling Points

  • Advanced Winding Technology: Proprietary polar-winding process yields stronger, more economical vessels
