These new bellows-type expansion joints absorb
pipe movement in any direction. They have the
important advantage of absorbing unlimited
amounts of lateral deflection without imposing
any pressure thrust on piping or equipment, thus
eliminating the need for heavy structural anchors.
They are manufactured in sizes from 3 in. to 72 in.
and with three different types of bellows, depending on the conditions.
