Piping

In the oil and gas industry, pipe systems transport liquids (liquids and gases) from one place to another. Pipeline engineering deals with the adequate transportation of liquids. Industrial process piping (and related components) can be made of wood, fiberglass, glass, steel, aluminum, plastic, copper, and concrete.

Built-in components, called fittings, valves, and other devices, usually measure and control the fluid’s pressure, flow, and temperature being pumped, typically included in the pipeline design. However, you can use sensors and automation interchangeably. Control is considered part of the instrument design.

The piping system is recorded in the instrumentation diagram (P&ID). If necessary, you can clean the pipe using a cleaning process. In addition, the piping system sometimes refers to piping design, a detailed description of the location of the process.

In the past, it was sometimes called drawing, engineering drawing, engineering drawing, and design. Still, today it is usually done by designers who have learned to use a computer-aided drawing or computer-aided design (CAD).

Most people are familiar with the piping system because it is a form of fluid transportation that provides drinking water and fuel to homes and businesses. The sanitary pipeline also discharges wastewater in wastewater to discharge the exhaust gas in the open air.

The fire extinguishing system also uses pipes, which can transport non-potable water or drinking water, or other liquids to extinguish fires. In addition, many other industrial uses are essential for transporting unprocessed and semi-finished liquids for processing into more valuable products. Some of the more exotic materials used in construction are Inconel, titanium, chromium-molybdenum, and various other steel alloys.

Stress Analysis

Pipe stress engineers typically check process piping and power piping to verify that the routing, nozzle loads, hangers, and supports are correctly placed. Also, they contain that allowable stress is not exceeded under different loads such as sustained loads, operating loads, pressure testing loads, etc., as stipulated by the ASME B31, EN 13480, GOST 32388, RD 10-249 or any other applicable codes and standards.

In addition, it is necessary to evaluate the mechanical behavior of the piping under regular loads (internal pressure and thermal stresses) under occasional and intermittent loading cases such as earthquakes, high wind or particular vibration, and water hammers. This evaluation should be performed with the assistance of a specialized (finite element) pipe stress analysis computer programs such as AutoPIPE,  CAEPIPE, CAESAR, PASS/START-PROF.

In cryogenic pipe supports, most steels become more brittle as the temperature decreases from normal operating conditions, so it is necessary to know the temperature distribution for cryogenic conditions. In addition, steel structures will have areas of high stress that may be caused by sharp corners in the design or inclusions in the material.
