Piping is a vital part of any system. Whether it is a vehicle, machinery, or an entire building, piping ensures that the fluid making up the system has direct and unimpeded access to its destination. Piping is also vital for ensuring that fluids are transported in the safest, most efficient way possible. In general, piping is designed to ensure that fluids do not come into contact with air and prevent contamination by minimizing pressure drop. This blog covers the basics of piping engineering and how it is important for engineers who work with fluids like gases, water, and oil. The information presented here should be useful for students who want to understand piping systems and the impact they have on our daily lives.
Pressure Drop Calculations for Pipes
– Pipe pressure drop is the difference in pressure between pipe and surrounding atmosphere. This is calculated using the appropriate codes, standards, and methods described in ASME B31.3 or EN 13480.
– Pneumatic testing can be used for pressure drop calculations, but it is more accurate for small changes in air pressure than for large changes.
– Pipe wall thickness can be calculated using predefined piping materials, such as schedule 40 or 60P. It also depends on the application, such as fluid flow, pressure drop, and physical properties of the fluid.
– Stress analysis is an important factor in pressure drop calculations. It’s used to determine pipe wall deflection under static loads and dynamic loads caused by water flow or gas flow.
– Industrial piping engineering has three major subfields: piping material, piping design, and stress analysis.
Industrial piping engineers work with a variety of different material types and designs to meet customers’ needs and ensure safe operations. They are responsible for developing specifications and designing pipelines to meet safety requirements, environmental regulations, and mechanical specifications.
They also ensure that pipelines are built according to specified standards and specifications to ensure proper installation and functioning of the system.
Fluid Flow Calculations in Piping Systems
– Fluid flow calculations are important in the design of piping systems.
– Piping engineers must have the necessary tickets and insurances for the proper mobilization of a piping system.
– A piping engineer must be aware of the various types of fluids and their respective flow rates and pressures as per standards or legislation. This knowledge is essential to specify, design, and troubleshoot piping systems accurately.
– Stress analysis is used to ensure that the routing and nozzle loads of a piping system are correctly placed and selected. In this process, the stresses acting on a pipe or conduit are calculated to determine if it can withstand the forces applied.
– Pneumatic testing is often used to test piping systems when moisture is undesirable or residual water cannot be removed. Hydrostatic pressure is far less in comparison to a piping system subjected to pneumatic pressure.
A piping engineer must possess an extensive knowledge of fluid mechanics, structural mechanics, and hydraulics for effective design and operation of a piping system.
Pipe Stress Analysis and Calculations
A Pipe Wall Thickness Calculator for predefined Piping Materials is available for calculating the design wall thickness for predefined piping materials for internal pressure based on the 2014 edition of ASME B31.3. This calculator is a useful tool for pipe stress analysts to calculate the required wall thickness from material properties, such as specified yield strength and tensile strength, and other factors. The calculated thickness should be taken as a guide and not as an absolute minimum value. The analysis must be carried out taking into account other critical factors such as stresses in the long term due to curvature-bending or distortion at inner or outer surfaces of the pipe and any additional loads that may be applied during stress analysis.
The use of dynamic pipe bending analysis software has become mainstream to provide accurate and efficient solutions in pipe stress analysis with better results compared to manual calculations, which are time consuming and prone to errors. Besides, Pipe stress analysis is a necessary process before designing pipes according to all prevailing legal standards, take into consideration local conditions, pipeline size, capacity, rotation speed etc. It also helps in preventing any potential safety hazards in pipelines by identifying cracks or defects in them before they lead to failure.
Pipe stress analysis is especially important for small diameter pipes, because these have higher probability of experiencing large deformations owing to high pressures than large diameter pipes due to low pressures. So it becomes vital to conduct proper analyses before constructing them.
Selection of Piping Materials
Piping materials play a vital role in the safe and efficient operation of a variety of systems. They are used for the construction and maintenance of pipelines, water and gas pipes, waste handling systems, and other infrastructure. To ensure effective operation, various factors such as environmental conditions, pressure, temperature and service requirement should be considered. The selection of suitable materials for piping systems depends on these factors. Every material has properties suitable for different applications.
In some cases, multiple materials may be required to serve a particular function or application. For instance, steel and glass are used to construct pipeline systems because they have high strength and durability. Different materials have different advantages and disadvantages. Some are expensive while others are easy to maintain and clean.
The proper selection of materials ensures the safety and reliability of the system. Besides, it helps in reducing operating costs and greenhouse gas emissions as well.
Design Considerations for Piping Systems
Piping systems typically require specialized engineering for design and implementation. Piping engineers are responsible for developing a management system for the piping system, which includes monitoring the integrity of the system. They must consider various factors, such as mobilization, BPJS, accommodation/mess, and medical insurance. These considerations help to ensure that the piping system is able to withstand different loads and operate safely and efficiently. It is vital that they conduct stress analysis of the piping system to ensure that it can withstand different loads, such as sustained loads and pressure testing loads. Piping engineers are also responsible for ensuring the proper layout of piping systems in accordance with safety standards.
Types of Piping Systems
Types of Piping Systems
– Main engineering fields related to piping systems include piping material, piping design and stress analysis.
– Here, the term ‘Piping material’ refers to any material used for the purpose of connecting the components of a piping system together. This includes copper, steel, plastic, and more. Each of these materials has its own advantages and disadvantages.
– The term ‘Piping design’ refers to the process involved in designing and developing a piping system from concept to completion. This can involve identifying the correct type of piping system for a given application, determining how many pieces of that system will be needed, calculating the sizes of each piece required, and more.
– Last but not least, ‘Stress analysis’ is another engineering field revolving around predicting and understanding the loads placed on piping systems. This involves taking into consideration factors such as velocity, pressure, and temperature when making sure a system will be able to handle that input without damage or failure.
Now that you have a basic understanding of piping and piping systems, it’s time to shift your focus to piping applications. You can use the above information to choose piping materials, create piping drawings, and perform pressure drop calculations for piping systems. Further, select piping design methods based on material properties and system requirements.
