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.
