Key Engineering Highlights

  • Custom thicknesses from 5mm to 100mm to overcome field fitup gaps
  • 100% chemically inert virgin fluoropolymer composition
  • Steel-inserted variants prevent creep and maintain bolt load over time
  • Precision machined to ANSI B16.5 flange bolt circle diameters

All components are manufactured in our specialized industrial facility located at GIDC Chhatral, Dist. Gandhinagar, Gujarat. The seamless fluoropolymer liner completely shields all wetted metal surfaces from chemical attack and fluid contamination.

Lining Fluoropolymer Options

We select virgin grade fluoropolymers matched precisely to process chemistry and operating temperature:

  • PTFE: -29°C to +200°C, universal chemical inertness, in-house paste extrusion.
  • PFA: -29°C to +200°C, melt-processable, superior clarity and permeation resistance.
  • FEP: -29°C to +150°C, high dielectric strength and smooth non-stick surface.
  • PVDF / PP / HDPE: Cost-effective options for mild corrosive and water treatment lines.

Housing & Metallurgy Options

Rugged metallic outer shells provide high pressure containment and mechanical strength:

  • Cast Steel: ASTM A216 Gr. WCB for heavy-duty pressure valves and fittings.
  • Carbon Steel Pipe: ASTM A106 Gr. B seamless pipe spools with A105 flanges.
  • Ductile Iron: ASTM A395 / GGG40.3 for economical vibration-absorbing installations.
  • Stainless Steel: CF8 / CF8M (SS304/SS316) for highly corrosive external plant atmospheres.
