STEEL PIPING
Piping is very critical to an above ground supply installation. Location of every line, it's components, size and safety devices need planning by a person familiar with operations. Our experience in this field reveals a definite history of welded verses threaded pipe. If at all possible we weld all piping except where supplied manufactures equipment is threaded.
C.U.I. manufactures it's own methanol injectors for L. P. supply delivery line and bobtail unloading breakaways. Also, we have a special arrangement of piping that looks appealing as an installed system. We manufacture most piping on site to fit.
Underground piping, regulated by Maryland Department of the Environment and must meet certain requirements depending on usage.
Regulators, shut off valves, globe valves, metering devices, safety relief valves, expansion joints are some of the various components used in a tank installation.
