After take a break for few days, Piping & Fabrication ready to go again and this is the other topics from this blog, and I believe this will be more interesting.
MANUFACTURING OF METALLIC PIPE
DEVELOPMENT OF COMMERCIAL PIPE-MAKING
There have been increasing societal demands for modern structures and facilities and concomitant increased emphasis on safety and reliability of equipment under all operating conditions. Piping manufacturing processes have been developed to provide the quality and reliability commensurate with these demands, together with economically feasible production methods. To meet the more stringent reliability goals, the quality control of the piping manufacturing process from the production of the raw material to the finished product is of significant importance. Driving the need for process quality improvement are the social and economic consequences of equipment failure in critical applications such as power generation, chemical and petroleum production, and transportation.
This chapter considers the methods by which different types of metallic pipe are produced. It also considers the various steel-making processes which are important to the ultimate quality of the manufactured pipe.
Historical Background
The history of pipe manufacturing goes back to the use of hollow wooden logs to provide water for medieval cities. The use of cast-iron pipes in England and France became prevalent in the early nineteenth century. The first major cast-iron water pipeline for Philadelphia was obtained in 1817 and for New York in 1832. Distribution of gas for gaslights was initiated in England, using sheet iron drawn through a die to a cylindrical shape and with the edges welded together. In 1887 the first pipe was made of Bethlehem steel in the United States.
Seamless pipe manufacture was attempted in the mid–nineteenth century by various means; the Mannesmann process was developed in Germany in 1885 and operated commercially in England in 1887. The first seamless pipe mill in the United States was built in 1895.
In the early twentieth century, seamless tubes gained wide acceptance as the Industrial Revolution proceeded with automobiles, oil refineries, oil pipelines, oil wells, and fossil power generation boilers. At that time, the welded tube had not achieved the reliability of present-day electric resistance welded tubes. The development of pipe and tube production methods, together with the development of steel alloys capable of withstanding the demanding environmental conditions of temperature, chemistry, pressure, and cyclic thermal and pressure load application have enabled pipe and tube to be used reliably in the most critical applications, ranging from Alaskan pipelines to nuclear power generation plants.
World Tubular Product Production Capability
World production and consumption of iron and steel tubular products makes up almost 14 percent of the worldwide crude steel conversion. World production of steel tubular products is continuously increasing to meet the demands of worldwide industrialization and growing population. The production of iron and steel tubular products vary depending on a wide range of worldwide economic factors such as oil exploration, power generation plant construction, and automotive production.
For example, in economic climates where oil prices are low, there is less incentive to drill new oil wells. Consequently, the production of steel pipe for oil drilling casings would be reduced. Similar examples of steel pipe production as a function of economic climate can be seen in the power generation and automotive industries. Total world production of pipe is an integration of the effects of the local national economic climates throughout the world.
