The AFA Style 99 rubber expansion joints are specially crafted in a spherical shape. Reinforced with steel wire and nylon, these rubber balls undergo vulcanization under high pressure. These joints come with either floating metallic flanges or MCB unions. Thanks to its spherical shape, it offers high resistance to explosion. Its elastic structure provides several benefits:
SUPERIOR ABSORPTION OF VIBRATION, NOISE, AND SHOCK
The AFA Style 99 rubber expansion joints are designed to mitigate vibrations, noise, and inherent movement in piping systems. Installing these joints allows equipment to move freely, reducing vibration and sound typically found in metallic joints. They cushion against water hammer, pumping impulse, and waterborne noise.
GREATER COMPENSATION FOR ELONGATION, COMPRESSION, LATERAL AND ANGULAR MOVEMENT
Machines such as pumps, chillers, cooling towers, compressors, and piping systems can misalign due to wear, load stress, and foundation settling. The AFA Style 99 joints account for lateral, torsional, and angular movements, preventing damage and reducing costly downtime in plant operations.
EXCEPTIONAL PRESSURE RESISTANCE
The spherical structure combined with special reinforcing nylon gives the AFA Style 99 joints notable resistance to internal pressure. They exhibit outstanding resistance to burst pressure.
BROAD RANGE OF POLYMERS
These joints can be produced using various polymers to cater to different fluid applications. Choices include Neoprene, EPDM, Natural Rubber, Nitrile, and more.
VERSATILE FLANGE TYPE AND MATERIAL
The flanged end joints can come with various flange combinations, such as DIN, ANSI, JIS, BS, and other special types. They can also be paired with different flange materials like carbon steel, stainless steel, bronze, brass, and PVC, catering to a multitude of applications.
EASY INSTALLATION WITH METALLIC FLANGES
The joints are equipped with loose, rotatable metallic flanges, simplifying the installation process and reducing time.
ADAPTABLE UNION MATERIAL AND THREAD STANDARD
The AFA Style 99 TU, TUA, and TUF rubber expansion joints offer compatibility with different union types. Options with NPT threading are available on demand, with the AFA 99 TU and TUF typically employing a malleable iron union with SSP threading.
ROBUSTNESS AND QUALITY
Made from special synthetic rubber and under stringent quality control, every production step of the AFA Style 99 joints is rigorously monitored and documented prior to shipping.
ADDITIONAL BENEFITS
No need for gaskets and packing.
Economical due to bulk production.
