Line
pipe is a type of steel pipe that is used for transporting materials
through pipelines across the country. Line pipe can be used to transport
petroleum, natural gas, oil, and water. It is a durable pipe that must meet
certain specifications and regulations. This pipe typically has a high strength
and durability in order to withstand high pressures. At Sunny Steel, we sell
and distribute line pipe in a complete variety of sizes, lengths, diameters,
and grades.

What is Line pipe?
What is Line PipeLine pipe is a type of pipe that is manufactured from
high strength carbon steel. It is typically made according to
metallurgical specifications that were developed by the American Petroleum
Institute (API). Line pipe can be used to build pipelines that transport a
variety of resources including natural gas, oil, petroleum, and water. This
pipe is available in a variety of diameters ranging from 2 inches to 48 inches.
Line pipe can include either seamless or welded carbon steel or stainless steel piping. Because line pipe
needs to withstand high pressures, there are important tests done on line pipe
to ensure it meets all of the requirements of steel chemistry, strength,
toughness, and dimensional characteristics. Using line pipe that meets the set
criteria will ensure safe and reliable pipeline service.The size and diameter
of line pipe that is required for a pipeline can vary based on the amount of
gas or liquid that a pipe is intended to carry as well as the pressures that a
line pipe must withstand. For example, in most cases a mainline, the principal
pipeline that delivers natural gas, will require line pipe that is around 16 to
48 inches in diameter. Smaller pipelines that deliver gas to the mainline or
take gas from a mainline can be constructed of 6 to 16 inch diameter line pipe.
One can determine the necessary diameter required for a pipeline by considering
the volume of gas or liquid that the line pipe will be carrying as well as the
pressure at which this will be transported. The thickness requirements for line
pipe are determined by the maximum operating pressure required for a pipeline.
This is based on published standards and federal regulations. Following proper
safety regulations when selecting and installing line pipe, will ensure proper
pipeline operation and prevent dangerous or hazardous situations.
