What is Piping System?

Piping system can be defined as when the piping components are joined together to perform some specific activities such as convey, distribute, mix, separate, discharge, meter, control, or stop the fluid flow is known as a piping system.

What is piping components?

Piping components are mechanical elements suitable for joining or assembling into a pressure-tight fluid containing piping system. Components includes pipes, tubes, fittings, flanges, hose pipes, gaskets, bolt-nuts, valves, expansion joints, traps, strainers, separators, control valves, safety valves, blind flanges, spectacle blinds, drip rings, etc.

What is pipe class and specification?

Pipe class is a document that specifies the type of components such as a type of pipe, schedule, material, flange ratings, branch types, valve types, valve trim materials and all other components which is specifically to be used for different fluids under different operating conditions in a plant. Pipe class is developed considering operating pressure, temperature, and corrosive environment. Different material specifications are segregated into separate “piping class”. Short code is used to cover all the information applicable to the given pipe class.

Piping specifications are technical documents that are generated by private companies to address additional requirements applicable to a specific product or application. Piping specification will provide specific or additional requirements for the materials, components, or services that are beyond the code and standard requirements.

Why did specification require?

  • It allows a purchaser to include special requirements as per design and service conditions.
  • It also allows to customize the product as per our requirements.
  • Please note requirements in the specification is must meet requirements as critical dimensions in industrial and application drawings.

For example: If you want A106 Gr B pipe with maximum carbon of 0.23% against standard requirements of 0.3% Max, you must be specified this requirement in your purchase specifications.

Normally in oil and gas facilities they generate their own specifications during the FEED stage which is front-end engineering and design, or sometimes uses readily available specifications from well established companies such as Shell, Bechtel, Chevron etc.
