The primary purpose of industrial and utility pipe systems is to transfer or process liquids and gases. Heating, cooling, filtering, steam generation, and compression are just a few of the applications that these systems are designed to handle. Manufacturers can build and produce more efficient fluid transfer techniques by applying some piping design ideas.
Carolina Process Piping has a lot of expertise designing and installing high-quality piping systems to satisfy the specific needs of our customers.
What are utility pipes and what do they do?
Pipes, cables, and other linear conveyance systems used to transfer power, water, gas, oil, wastewater, and other similar commodities are referred to as utility lines. Outfalls and intakes are examples of utility lines.
What is the definition of process piping?
The safest and most efficient way to carry fluids and gases through an industrial or manufacturing facility is through process pipework. Despite its resemblance to plumbing, process pipework is a distinct system made of materials tailored to the items it will convey.
What are the many types of piping systems?
Copper, galvanized steel, polyvinyl chloride (PVC), acrylonitrile butadiene styrene (ABS), and cross-linked polyethylene are the five main types of plumbing pipe materials still in use today (PEX). Also used is chlorinated polyvinyl chloride (CPVC).
In building, what is piping?
Pipework, commonly referred to as piping, is a system of pipes used to transport fluids. Pipework integrity requires careful design that adheres to a variety of concerns and principles.
Pipes, according to approved document B of the building requirements, “include pipe fittings and accessories.” A flue pipe and a pipe used for ventilation purposes, other than a ventilating pipe for an above-ground drainage system, are not included in the definition of ‘pipe.’
Pipes and piping components are manufactured to national standards such as ASME B31 Code for Pressure Piping or BS 1560 Circular Flanges for Pipes, Valves, and Fittings.
Pipework is made up of a variety of components, including pipes, supports, gaskets, flanges, bolts, valves, strainers, and flexible and expansion joints. The system is frequently documented in piping and instrumentation diagrams, and these are used to sense and control the pressure, flow rate, and temperature of the delivered fluid (P&IDs).
Utility pipes come in a variety of colors.
Because utilities are comprised of various sorts of materials, different section and positioning procedures are used.
Electromagnetic equipment with a transmitter and receiver is utilized for metal pipes and similar cables. Radio location and ground penetrating radars are used to test polymers and concrete.
Because of the nature of their composition, utilities such as petroleum products are permanently designated with posts and bollards. There are maps to help identify these utilities, but you’ll need some special equipment to get a precise and accurate position.
To designate lines, a specific sort of spray paint is employed, which is generally a neon color. To indicate the ownership of the lines on flags, a form of logo representing the corporation or municipal utility is utilized.
Companies who build irrigation lines for lawns and gardens frequently use flags as a form of advertisement. In this instance, landscapers will leave the sprinkler head open to avoid damage from tractors, construction equipment used for digging trenches, and fenceposts.
For subterranean services such as water, gas, electric, telephone, and cables, the United Kingdom utilizes a color code identical to that used in the United States. There is no published standard for the system, which is dependent on tradition. Contractors will use the color code to paint different colors onto the pavement to designate places with subsurface utilities.
For subsurface utilities, the National Color Coding System is as follows:
What is the distinction between a pipeline and a piping system?
Piping is typically connected to a variety of equipment and transports fluids via a complex network to be treated by that equipment. Pipelines, on the other hand, generally run straight and supply the feed for additional processing or convey the processed fluid or final product. In comparison to pipes, the number of equipment connections in the pipeline is quite low.
What’s the difference between utility and process piping?
Process piping is not regulated in the same way that plumbing or power pipes are. This is due to the fact that process pipe is not placed to provide building services, but rather to support a specific internal operation such as chemical manufacture or product refinement.
Engineering standards, not municipal codes, regulate the design and construction of process pipe systems. Process pipework will be governed by the American Society of Civil and Mechanical Engineers (ASCME) in many sites. Process piping, unlike plumbing, is not part of a building’s mechanical system.
That isn’t to suggest that process piping isn’t subject to federal regulation. For safe operation, process pipework must also adhere to OSHA regulations. Some process piping systems may also necessitate preliminary permitting, inspection, and approval.
Process piping also has a wider range of pipe materials to choose from. Based on the intended use, budget, and type of fluids to be transferred, facilities can select the best piping material. Process pipe systems can be used to support a wide range of industrial or manufacturing processes, including:
- Mixing and separating fluids
- Stopping and beginning the flow of fluid
- Pressurization/depressurization
What is the definition of power piping?
Power pipe refers to piping systems and components that are not part of a building’s plumbing system and are used in electric power plants, industrial and institutional plants, utility geothermal heating systems, and central and district heating and cooling systems.
What is the ASME piping code?
ANSI B31 was the previous name for ASME B31. 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 are all covered under the B31 Code for Pressure Piping.
Pipe, flanges, bolts, gaskets, valves, relief devices, fittings, and pressure-holding sections of other pipeline components make up piping.
