The Uses of Seamless Carbon Steel Pipe
A seamless carbon steel pipe has many uses, thanks to the tough and versatile nature of carbon steel. This pipe is seamless, so it tends to have better durability and strength, making it useful for construction work. Many heat-transfer systems use a seamless carbon steel pipe network to the hot or cold liquid or gas in an area. The petroleum industry uses this pipe to carry large amounts of petroleum from the ground to the surface, and this pipe also is commonly used to transfer the petroleum to other places. This pipe is easier to form and bend than other carbon steel pipes, so it also can be used in places where custom angles and shapes are needed.
Many large structures use pipes in the deep foundation, the section that is underground. If a seamless carbon steel pipe is used, then it is driven into the ground by a large machine and may be filled with concrete after it is pile-driven to protect the pipe and make it even sturdier. This type of pipe generally is very durable and does not bend easily from stress, so it is uniquely suited for deep foundations.
Heat transfer systems are used in many structures, and one way to carry the heat around the structures is with a seamless carbon steel pipe. A fluid or gas, such as hot water or steam, normally is sent through the pipe and travels the length of the structure. The steel is corrosion resistant, and the lack of seams further protects this pipe from warping during use, so this pipe commonly is used for this purpose.
Similar to a heat-transfer system, the petroleum industry typically will use a seamless carbon steel pipe to transfer petroleum. This pipe typically is much larger than carbon steel pipes used for other purposes to allow the pipe to carry the large amount of petroleum. Depending on where the pipes are positioned, they can be used to carry the petroleum from the earth into a holding tank, or from tank to tank.

World Steel Pipe Industry
This report offers historical demand data (2004, 2009 and 2014) plus forecasts (2019 and 2024) by application for six world regions and 19 major countries. The study also considers market environment factors, examines the industry structure, evaluates company market share and profiles 25 industry players worldwide.
World demand to rise 3.5% annually through 2019
Global demand for steel pipe is forecast to advance 3.5 percent per annum through 2019 to 79.7 million metric tons, with growth paced by continued strong increases in developing markets. The pace of gains will decelerate from that of the 2009-2014 period as construction activity slows in China and numerous other developing countries, and oil and gas exploration moderates in North America after a period of rapid growth.
Equipment manufacturing market to see fastest gains
The oil and gas market is the dominant application for steel pipe. Steel makes up the vast majority of pipe used in oil and gas transportation and especially production due to its high strength and pressure and thermal resistance. Demand for oil and gas pipe saw healthy growth between 2009 and 2014, driven by growth in China and North America; however, advances are expected to decelerate because of slowing exploration and drilling due to already high production and lower oil prices.
Steel pipe used in equipment manufacturing is expected to see above-average growth through 2019. Although efforts to simplify automotive manufacturing and reduce the weight of finished products will check more robust demand advances, continued expansion in durable goods manufacturing will support strong growth. Structural steel will also see growth above the global average through 2019. Although slowing expansion in the oil and gas market (as structural steel pipe is often used in well construction) will limit advances, construction spending growth will drive demand.
Steel pipe also sees significant usage in construction markets, where it is used in a variety of applications, such as conduit, sewer, and drainage. However, unlike the oil and gas market, steel exhibits lower penetration in most applications due to price and performance advantages of other materials such as plastic.
Growth in China to slow but remain above global average
China, by far the world's largest national market, with 30 percent of global demand in 2014, was a primary driver of demand growth for steel pipe between 2004 and 2014. Expansion across all steel pipe markets, especially in OEM, structural, mechanical, and construction applications, sparked global steel pipe demand.
