High Pressure Gimbal Expansion Joint for a Chemical Plant in Europe

We have successfully completed the design, manufacturing and testing of one unit High Pressure Gimbal Expansion Joint for a Chemical Plant in Europe.

 

What makes this a special unit is that the bellows are manufactured in Alloy C276 (2.4819) UNS N10276 and all its hardware (gimbal system, flanges, supports, reinforcement rings, etc. in A240 Tp 304H and that it has been designed for 20.0 barg (290 psi) and has been tested at 42.76 barg (609 psi).

 

Alloy C276 is a nickel alloy which exhibits excellent corrosion resistance in harsh environments. It is known as the most universally corrosion resistant material available today.

 

Type 304H has a high carbon content making the steel more suitable for use in applications where elevated temperatures are present. It is an austenitic chromium-nickel steel alloy and the greater carbon content delivers an increased tensile and yield strength.

 

The material is recommended for use in ASME pressure vessels in working service above 525 °C due to the grade's heat resistant properties
