What is this method?

Pipe is a tubular product used to convey a fluid. The pipe sizes are generally identified as nominal bore (NB) or nominal pipe size (NPS). Industrial process piping can be manufactured in with different materials such as wood, fiberglass, glass, steel, aluminum, plastic, copper, concrete, etc., Pipe fittings are used to connect lengths of pipes to construct a long piping system; commonly used fittings are flanges, elbows, tees, reducers, expansion bellows etc.,

Why is this method?

The in-line components, which is known as fittings, valves, and other devices, typically sense, and control the pressure, flow rate and temperature of the transmitted fluid, and usually are included in the field of Piping Design. In the similar way, a piping system is a network of pipes, fittings and valves intended to perform a specific job i.e. to carry or transfer fluids from one equipment to another. The plumbing network supplying water at your home is a common example of a piping system. Other more rigorous examples include steam piping in a power plant, milk piping in a dairy, paint piping in a paint manufacturing plant, oil piping in a refinery, etc.,

When is this method?

Prior to initial operation, and after completion of the applicable examinations required by ASME guidelines, each piping system shall be tested to ensure tightness. The test shall be a hydrostatic leak test in accordance with rules prescribed except as provided herein.

  1. a. At the owner’s option, a piping system in Category D fluid service may be subjected to an initial service leak test in accordance with in lieu of the hydrostatic leak test.
  2. b. Where the owner considers a hydrostatic leak test impracticable, either a pneumatic test in accordance with guidelines or a combined hydrostatic-pneumatic test may be substituted, recognizing the hazard of energy stored in compressed gas.
Roles and responsibilities:
  1. The Piping Supervisor must develop plans and specifications for the project. They create plans according to procedures and regulations that account for safety, communicating these plans to their team.
  2. Piping Supervisors manage the project from start to finish. They direct crews of assistant staff such as Piping Helpers, assign them tasks, and ensure that the project flows in a timely manner and according to the project plans and specifications.
  3. The Piping Supervisor participates in and oversees the installation and repair of piping systems. This requires a full understanding of the project plans and specifications and an ability to use all relevant tools and equipment.
  4. Piping Supervisors are ultimately responsible for ensuring both the safety of their crew and the environment. It is up to them to make sure that specifications are in accordance with safety procedures and regulations, and that the work area follows all safety guidelines as well.
