Advantages of PEBCO/Meccom

Pebco Sales are Designers and fabricators of devices used to compensate for thermal expansion / contraction, lateral offset, and angular misalignment. They are most commonly known as “Expansion Joints” or “Flexible Connectors” in the U.S.  They are mostly called Kompensators in Europe. They are most commonly used in piping and ducting systems when the pipe or duct is adjacent to vibrating and other equipment. The expansion joint is designed to relieve stresses between the duct or pipe and the equipment.  Long runs of pipe or duct need expansion joint to absorb the thermal growth of the pipe or duct as they get hot.  The expansion joint will compress as the pipe or duct expands relative to the co-effiction of growth per their temperature over ambient.  Equipment where expansion joints are most used is of course long runs of pipe or duct, pumps, valves, pressure chambers, scrubbers, precipitators, dust collectors, drop chutes, furnaces, and ovens.

Why Choose PEBCO/MIPCO?

We have the design capability to develop and build special designs that fit specific tough applications and will also help to increase life.  Many times placement, i.e. location of the expansion joint, can help increase service life and provide lower spring rates to allow for greater equipment life.
Special materials that most of our competitors are unfamiliar with can be used for very tough abrasive and corrosive applications.
