Steel Pipes Used For Pipeline Application

In most cases, utility systems such as those for water, sanitary or storm water, air, draining or low-pressure oil or gas service applications often use the nonsteel piping material systems. However, for the vast majority of the “pressure” piping systems encountered, steel pipe is required.

As we all know, there are many different types of pipelines that are used for different applications around us, which generally consist of very long pipes with large diameters and are used to transport products such as crude or refined oil and natural gas long distances. Transportation pipelines can stretch between cities, countries and even continents.

Steel pipelines, which lie buried for hundreds of years, has extraordinary properties including excellent stress crack resistance to natural gas and its contaminants, low permeation to methane and hydrogen, high HDB rating at 20°C, 60°C and 80°C, superior impact resistance, squeeze off, and dependable UV performance for outside storage. Generally, ERW pipe (Electric Resistance Welded steel Pipe) are used for oil and gas processing and transmission lines registered and assures consistent quality in its application. These oil and gas pipes are equally good in hot or wet applications such as river crossings and rough terrain. The use of steel provides standard for pipe suitable for use in conveying gas, water and oil in both the oil and natural gas industries.

Without pipelines our civilization would come to a screeching halt. There are two types of steel pipe, one is seamless steel pipe and another has a single welded seam along its length. About how to make a choice between welded pipe and seamless pipe, you can take into consideration from the reality. On basis of grades, the steel pipes are generally used by petroleum industry and so the standards are defined by American Petroleum Institute. The factors taken into account are based on applications like environment, weight, pressure, diameter and most importantly cost.

For petroleum applications, pipe materials that meet American Petroleum Inst. (API), American Soc. for Testing and Materials (ASTM), ASME, and ANSI standards are used most often. All of these standards have very rigid design, specification, chemistry, and testing standardization and manufacturing requirements. Modern steel pipe manufactured to these exacting standards assures both high quality and safety in design.
