Resistoflex Metal Expansion Bellow with floating flanges for HVAC and industrial applications supplied by RMS Corporation.

APPLICATIONS

These joints are mainly used in pipelines for the conveyance of a liquid, gas or granular medium under lowest and highest temperatures involving a wide range of applications- Such as :

  • EXHAUST PIPES OF ENGINES AND TURBINES
  • SHIP INDUSTRY CHEMICAL AND PETROCHEMICAL PLANTS
  • POWER PLANTS
  • CONSTRUCTION MACHINE INDUSTRY
  • HYGIENIC APPLICATION IN FOOD INDUSTRY
  • AIRCRAFT AND NUCLEAR INDUSTRY
  • DISTRICT HEATING SYSTEM

ADVANTAGES

  • COMPENSATES FOR AXIAL
  • MOVEMENTS DUE TO THERMAL CHANGES
  • COMPENSATES FOR TORSIONAL AND ANGULAR MOVEMENTS ISOLATES VIBRATIONS,
  • DAMPENS NOISE AND PRESSURE SURGES FLOATING FLANGE EASES INSTALLATION
  • THE FLUID DOES NOT COME IN CONTACT WITH THE FLANGE MATERIAL

EVERY JOINT IS TESTED FOR PRESSURE & VACUUM for durability, long life & trouble free service

Description

Metallic Expansion Bellow with Floating Flanges

Overview

Metallic expansion bellows with floating flanges are flexible pipe joints manufactured from stainless steel bellows elements with loose (floating) flanges. The floating flange design allows for easier installation on existing piping and compensates for angular and lateral misalignment. Suitable for high temperature, high pressure and corrosive applications.

Features

  • Stainless steel bellows (304, 316, 321 grades)
  • Loose floating flanges for easy installation
  • Single or multi-ply bellows construction
  • Compensates for axial, lateral and angular movement
  • High temperature and pressure capability
  • Corrosion-resistant construction
  • Custom designs available

Applications

  • Industrial process piping (chemical, petrochemical)
  • Steam and condensate systems
  • Hot water and thermal oil piping
  • Exhaust and flue gas ducting
  • Power plant piping systems
  • Turbine and compressor connections
  • High-pressure industrial applications

Technical Specifications

  • Material: SS 304, SS 316, SS 316L, SS 321, Inconel
  • Flange Standard: BS10, ANSI B16.5, BS4504
  • Size Range: DN25 (1″) to DN1500 (60″)
  • Pressure Rating: PN10 to PN40
  • Temperature: Up to 600°C
  • Bellows Plies: Single or multi-ply (2-3 plies for higher pressure)
  • End Connections: Floating flanges, tie rods optional

Advantages of Floating Flanges

  • Easier installation – flanges rotate freely
  • Compensates for angular misalignment
  • No need for precise pipe alignment
  • Suitable for retrofit and replacement applications
  • Reduces installation time and cost

Benefits

  • Absorbs thermal expansion in piping systems
  • Reduces stress on equipment and pipe supports
  • Suitable for high temperature and pressure service
  • Corrosion-resistant stainless steel construction
  • Long service life with proper installation
  • Manufactured to international standards
