Power piping means piping systems and their component parts, that are not building services piping systems, and that may be installed within electric power generating stations, industrial and institutional plants, utility geothermal heating systems, and central and district heating and cooling systems. Power piping includes, but is not limited to, piping used in the distribution of plant and process steam at boiler pressures greater than fifteen pounds per square inch gauge, high temperature water piping from high pressure and high temperature boilers, power boiler steam condensate piping, high pressure and high temperature water condensate piping, and compressed air and hydraulic piping upstream of the first stop valve off a system distribution header. Process piping means piping systems and their component parts, that are not building services or power piping systems, and that may be installed in petroleum refineries, chemical, pharmaceutical, textile, paper, semiconductor, and cryogenic plants, and related processing plants and terminals.

Singh, Nawin, and Sajith Nair. The most common method to transport oil and gas within the energy industry is through the pipeline transmission system. However, the pipeline system is very expensive, greatly on account of material and construction costs.
The material cost is primarily driven by "linepipe cost", which is a function of pipeline size and thickness. The aim of this paper is to present a comparative study and arrive at recommendations to optimize the material cost of linepipe, through a rational selection of the governing design code for pipelines, design philosophy and material grade.
Hence, it is expected that the pipeline industry can benefit, particularly during the initial feasibility stage of evaluating the capital expenditure of a pipeline project. As the pipeline diameter and operating parameters are fixed in line with process requirements, for purposes of mechanical design, wall thickness will be the governing cost parameter to be assessed. There are broadly two methods of design being followed in the industry to calculate the wall thickness based on pressure containment criteria i.
WSD stress criteria or limit state. However, there is inherent conservatism in the allowable stress method as only a certain fraction of material strength has been factored. A recognition of this conservatism by the industry resulted in the limit state approach. A detailed comparison has been performed of available international design standards and the approach followed worldwide to develop the matrix and perform the parametric study.
To substantiate the findings, a case study for a typical pipeline project in the Middle East has been performed. FEM tool e. The paper deliberates on the design code, design method and linepipe material and provides recommendations on the judicious selection of these parameters which can ultimately lead to optimum CAPEX.

The integrity of a piping system depends on the considerations and principles used in design, construction and maintenance of the system. Piping systems are made of many components as pipes, flanges, supports, gaskets, bolts, valves, strainers, flexibles and expansion joints. The components can be made in a variety of materials, in different types and sizes and may be manufactured to common national standards or according a manufacturers proprietary item. Some companies even publish their own internal piping standards based upon national and industry sector standards. Piping standards define application design and construction rules and requirements for piping components as flanges, elbows, tees, valves etc. A standard has a limited scope defined by the standard.
Pipe covers a very large part of any process plant. If you look at the Oil Exploration platform, Refinery and Petrochemical complex one thing that catches the attention is a complex network of piping. Piping is used to transport various process materials from one equipment to another. But why? Process Plant is a place where a series of activities are performed in particular ordered to convert raw material into a useful product. Interconnected pipe and pipe components are used to transport raw material, intermediated product and final product to the desired location.
Standardization is the process of implementing and developing technical documents based on the consensus of different parties that include firms, users, interest groups, standards organizations and governments. Standardization can, and does, reduce the cost, inconvenience, and confusion that results from unnecessary and undesirable differences in equipment, systems, materials and procedures. Standards can also document accepted industry practice in areas such as safety, testing and erection. In process plants standardization is achieved by implementation of various standards, codes and recommended practices.
