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
