What is the ASME Code followed for design of piping systems in process piping?
B31 Code for pressure piping, developed by American Society of Mechanical Engineers – ASME, covers Power Piping, Fuel Gas Piping, Process Piping, Pipeline Transportation Systems for Liquid Hydrocarbons and Other Liquids, Refrigeration Piping and Heat Transfer Components and Building Services Piping.
What pipe is used for oil and gas?
Benefits and applications of stainless steel The main pipes used in the offshore Oil and Gas Industry are Duplex 2205 (22% Chromium, 5% Nickel) and 2507 (25% Chromium, 7% Nickel); and Super Duplex 2507 which has higher corrosion resistance.
What are the factors to be considered when designing a pipeline?
There are many factors that affect the pipe-wall-thickness requirement, which include:
- The maximum and working pressures.
- Maximum and working temperatures.
- Chemical properties of the fluid.
- The fluid velocity.
- The pipe material and grade.
- The safety factor or code design application.
What’s the difference between code and standard?
A code is a model, a set of rules that knowledgeable people recommend for others to follow. It is not a law, but can be adopted into law. A standard tends be a more detailed elaboration, the nuts and bolts of meeting a code.
What diameter are oil pipelines?
4 to 48 inches
Oil pipelines are made from steel or plastic tubes with inner diameter typically from 4 to 48 inches (100 to 1,220 mm). Most pipelines are typically buried at a depth of about 3 to 6 feet (0.91 to 1.83 m).
What are the 4 design factors?
The four resultant product design dimensions are affective, cognitive, ergonomic and reflective.
What are the standards for oil and gas pipelines?
If there are no codes or standards that specifically apply to the oil and gas production facilities, the design engineer may select one of the industry codes or standards as the basis of design. The design and operation of gathering, transmission, and distribution pipeline systems are usually governed by codes, standards, and regulations.
What do you need to know about offshore piping?
This standard covers the basis for design and layout of process, drilling and utility piping for offshore oil and/or gas production facilities. Relevant parts of this standard may also be used for control room, laboratory, helideck and other facilities around the platform.
What are the Recommended Practices for piping construction?
The documents define the application design, construction rules, and necessary requirements for piping components like valves, flanges, elbows, tees, etc. Recommended practices, as mentioned before, are mostly developed by the same organization, group or committee that developed the standards.
Why are pipeline design considerations and standards important?
The considerations and standards guiding pipeline design insures stability and integrity in the industry. The fluid flow equations and formulas presented thus far enable the engineer to initiate the design of a piping or pipeline system, where the pressure drop available governs the selection of pipe size.
