Flange Connections for Aggressive Fluids

Chemical plants require demountable, leak-free connections throughout the plant. Our HDPE flange fittings with metal backing rings provide corrosion-resistant joints between HDPE pipelines and equipment handling acids, bases and specialty chemicals.

The flanged design allows easy maintenance access while HDPE's chemical inertness protects against corrosion and contamination, delivering a long service life in the most demanding processing environments.

Key Features

  • Excellent chemical resistance to acids, bases, and solvents
  • Smooth interior surface prevents scaling and buildup
  • Leak-free joint systems
  • Compliance with industry standards (ISO, ASTM)
  • Customizable for specific chemical applications

Applications

Acid Handling

Piping systems for sulfuric, hydrochloric, and nitric acid transport.

Specialty Chemicals

Transport systems for specialty and high-purity chemicals.

Chemical Process Lines with Verified Compatibility

Every chemical attacks polymers differently. Our line sheets map each medium, concentration and temperature to a verified pipe material before a single fitting is quoted.

Industrial duty demands piping that survives aggressive media, thermal cycling and continuous mechanical stress. We supply complete fabricated systems - bends, tees, reducers and custom weldments - documented with material certificates and pressure test records for seamless site acceptance.

From chemical dosing lines to cooling water headers, every assembly is manufactured under ISO 9001 controls. Our engineering team supports the full cycle: line sizing, stress review, fabrication drawings and on-site fusion supervision where required.
