The Benefits and Application of Steel Pipes

Steel pipes are the most commonly used pipes in water supply systems. They are also used in pipelines for natural gas, and sewerage systems. Although comparatively expensive to other pipes, they hold the advantage of being able to withstand high pressures and are available in more convenient lengths, and can also be welded easily, thereby resulting in lower installation and transportation costs. These types of pipes are highly efficient and can be used in small diameters as needed and are 100% recyclable compared to other materials. The pipes can further be melted down and turned into other usable material in industry. Furthermore, the high strength of these pipes and resistance to damage caused by human errors, tree roots, and extreme weather conditions make these pipes the ideal choice for most water and sewerage supply systems.

The disadvantages of steel pipes include thermal conductivity, which is very poor as there is a difference in heat transfer. These types of pipes are usually bonded with aluminum or copper to increase thermal conductivity and improve heat transfer. Cost is another issue, as these pipes are expensive and this is guided by the misconception of being a one-time purchase. However, Carbon steel pipes are difficult to fabricate and lack the malleable qualities that other materials have, therefore repairs and replacements of steel pipes are extra difficult.

Steel pipe is required in the majority of oil and gas production and pipeline applications. ASME A53 and A106 and API 5L seamless, electric resistance welding (ERW), and submerged arc welding (SAW) steel pipe are commercially available and most commonly used in pipeline systems. PVC, fiberglass, polypropylene, and other materials may be used in low-pressure and utility applications. ASME B31.4 and B31.8 allow the use of alternate materials in very restricted applications. Seamless pipe is seldom used in pipeline applications because of the higher cost and limited availability. From a design and regulatory perspective, pipe made with ERW and SAW seams is equivalent to seamless pipe and is less costly. Note: This is not true for piping systems designed in accordance with ASME B31.3.

For high-pressure pipeline, high-grade pipe, such as API 5L grades X42, X52, X60, and X65, is selected because much thinner wall pipe can be used, which significantly reduces pipe costs. Construction cost savings also are realized, as the welding time is reduced and material shipping/handling costs are reduced.

Steel pipe is normally used for pipelines operating at a pressure of 100 psig or more. Steel pipe withstands high pressures, is durable, and has a long operating life cycle. Fiberglass, PVC, or high-density polyethylene (HDPE) pipe is used in certain instances for low-pressure gas gathering pipelines. Components of the pipeline include the following: pipes, valves, fittings, and equipment such as metering, pumps, and compressors.
