Carbon steel is a popular material used for fuel oil applications and is valued for its durability and reliability. It is common, readily available and very familiar to plumbers and pipefitters. Because fuel oil is non-corrosive, there is no concern for scaling and corrosion on the inside of the pipe. However, when installed outdoors, uncoated steel pipe can and will rust over time

System Application and Material Usage

Steel pipe is available in a variety of wall thicknesses with "standard wall" being the most common for use in fuel oil systems because of the relatively low operation pressure.

Carbon steel’s combination of mechanical properties continues to make it a popular choice for fuel oil applications. The strength and elongation properties of steel allow it to withstand stresses and strains without breaking under shocks from surges, water hammer and other man-made disturbances.

Steel pipe may be installed using a variety of joining methods including grooved, welded, flanged, threaded and other mechanical joining methods. Longer lengths enable faster and more economical installations.

Carbon steel pipe is a very familiar material for plumbers and pipefitters and the numerous special tools required will be on hand. They include a pipe vise or tripod to hold the pipe, a heavy duty cutter to slice the pipe, a ratchet and assorted pipe threading dies, a reamer and cutting oil, pipe wrenches, a pipe burring tool, and Teflon tape or pipe-joint compound, commonly referred to as pipe dope.


Our products meet the oil industry’s needs for onshore transportation and are ideal for use in extreme conditions such as corrosive environments, low and high temperatures, high pressure and sour service.
