Metal Expansion joints
  Bellows Capsules
Hydro-Flex Hose supplies custom designed bellows capsules according to the Expansion Joint Manufacturer's Association (EJMA) guidelines. Our strict manufacturing processes and quality control procedures insure a precise product every time. Single ply and multi ply bellows are available in sizes 1-1/2" through 96" diameter. Metal bellows can be made in most alloys. T-321 stainless steel is used as a standard due to its excellent forming properties and high temperature properties. Other common alloys stocked at Hydro-Flex Hose include T-316 and T-304 stainless steel, Inconel 625, Monel 400 and Hastelloy C276.

  Single Bellows Expansion Joints
Hydro-Flex Hose supplies custom manufactured single bellows expansion joints in 1-1/2" through 96" diameters. Bellows design follows EJMA (Expansion Joint Manufacturers Association) standards and all welding is in accordance with ASME Section IX. T-321 stainless steel is the most widely used material for bellows applications. Hydro-Flex Hose can also supply bellows in other alloys such as Inconel 625, Inconel 600, Inconel 825, Monel 400, Hastelloy C276, T-316-L stainless steel, T-304 stainless steel, T-310 stainless steel and many other alloys.

  Universal Bellows Expansion Joints
This type of joint is generally designed to absorb large amounts of lateral deflection and possibly a small amount of axial compression. The ability to absorb motion in multiple planes makes it an ideal expansion joint for systems where the main anchors are not practical. Other applications include tank settlement and seismic building separations.

  Exhaust Bellows Expansion Joints
Expansion joints provide the ultimate vibration isolation and flexibility at the engine exhaust manifold. System expansion joints are required to absorb the thermal expansion of the piping. Hydro-Flex Hose is eager to assist in selecting the proper expansion joints for your system.
  Externally Pressurized Expansion Joints
 
This heavy duty expansion joint is used in applications with large amounts of axial movement. Hydro-Flex Hose offers a standard 350 Series single expansion joint with 4", 6", and 8" axial travels. For movement up to 16" axial travel, a dual expansion joint can be designed. It must be placed in the center of the piping run as it compresses from both ends.
