The pressure thrust imposed on the system piping anchors is nearly eliminated with the pressure balanced expansion joint design. Triad Bellows designs and manufactures both the 90 degree elbow style( shown) and the inline pressure balanced style. When space limitations prevent sturdy enough anchor designs this metal expansion joint comes to the rescue. Let our design engineers help you determine the right expansion joint for your piping system.
The Tied Universal Expansion Joint design has large lateral offset capabilities. This double bellows style expansion joint can also be engineered for large amounts of axial compression or a combination of both. Tie rods are designed to absorb the full pressure thrust of the bellows eliminating the need for anchors when used for lateral offset only. The universal expansion joint can be used in a wide variety of applications from engine exhaust piping systems, steam piping and even for seismic isolation. The design team at Triad Bellows Design and Manufacturing is always ready to assist with your next project.
Bellows Capsules for Fabricators. Triad Bellows Design and Manufacturing will custom design your metal bellows specifically for your application. We use sophisticated engineering software developed to meet the strict guidelines of the Expansion Joint Manufacturing Association (EJMA) 10th Edition. If your requirement has already been engineered we can make your bellows to your design. We specialize in multi-ply bellows construction which is your best choice for the ultimate bellows cycle life. Our goal is to simplify the process for expansion joint fabricators. The bellows necks or tangents can be precisely expanded to fit your end fittings. Flow liners, vanstone stub ends and spacer tubes can be furnished and pre-fit to the bellows to speed up the welding process. To make the assembly welding process even easier the bellows necks can be banded and resistance welded providing a thicker neck to attach ...
Externally Pressurized Expansion Joints for extreme axial travel. Triad Bellows custom designs externally pressurized expansion joints up to 18” diameter with axial compression capabilities up to 16” travel. All expansion joint are manufactured in the United States and can be custom designed with all stainless steel construction, Inconel bellows, ANSI forged flanges etc… By design the externally pressurized expansion joint is extremely rugged and has several built in features. The construction provides an external cover for the bellows and a flow liner for the media. Special lengths are never a problem.
With modular tooling Triad can manufacture even the odd diameter bellows and metric sizes. With the addition of new tooling our size restriction will increase to 144” diameter. As with the smaller bellows we can also make the larger diameters with multi-ply construction for increased cycle life and movement capability. High temperature T-321 stainless steel is our standard material of construction but T-316, T304, T309, T310, Hastelloy X, Hastelloy C276, Inconel 625 and other alloys can also be used in any of our metal bellows designs. To insure that you get the best expansion joint products available Triad Bellows designs and manufactures ALL metal bellows in accordance with EJMA 10th edition.
Triad specializes in multi-ply metal exhaust bellows which provides the best cycle life available. We stock special flanges to mate with most major engine manufacturers exhaust manifolds and turbo chargers. Floating flanges are standard for Caterpillar, Cummins and Detroit / MTU and Waukesha exhaust expansion joints. For high flow velocities Flow liners are recommended. All expansion joints can be manufactured to any length that best suits the available space. Any weldable fitting can be attached to the outlet side of the bellows to make the installation quick and easy. Manufacturing custom expansion joints is our business, let us know how we can help.
