Industrial pipeline refers to the pipes used within industrial operations. Industrial piping is characterized as a system made up of a series of components that are put together with the aim of transferring a substance whether it be a liquid, gas, or fine particles. Pipe fittings are components used to join pipe sections together with other fluid control products like valves and pumps to create pipelines.
Industrial piping, fittings, valves, pumps and instruments constitute the industrial piping system Industrial piping systems transfer fluids throughout manufacturing plants. These pipes and fittings are used in industries such as chemical plants, oil refineries, metal fabricators, pharmaceutical facilities, food processing companies, water treatment plants, mining operations, power generation plants, pulp mills, oil drilling platforms, etc. Industrial piping designs and components vary greatly based upon what industrial application of pipe, what materials are used, and the required service life of the pipe.
Industrial pipeline and fittings can be made from a range of different materials such as aluminum, iron, concrete. The material used for the piping is determined by the industry it’ll be used for. It’s essential that the operating conditions align with the piping material to ensure that the material used is safe to be used under operating conditions of potential temperature, erosion, pressure, or corrosion. Pipes and fittings need to meet certain criteria regarding their strength, durability, flexibility, resistance to corrosion, ease of installation, cost, availability and environmental impact. They need to have excellent mechanical properties and maintain these properties over time, even under extreme conditions. In addition, they need to be able to withstand various stresses, such as vibration, pressure fluctuations and temperature changes. A variety of materials and designs are used to construct these industrial systems. Different materials require different types of pipe joints to ensure maximum performance over the life of the system. For example, polyethylene pipes require crimp fittings, whereas stainless steel pipes require threaded unions.
The uneven thickness of pipe fitting wall mainly occurs in the part with the largest deformation.If the wall thickness of the back of the elbow is thinner than other parts;The thickness of the pipe mouth and the wall of the fitting body are different.It is stipulated in the relevant national standards that the maximum thickness reduction of the wall thickness of the pipe shall not exceed 12.5 of its nominal thickness. However, the field measurement shows that the thickness reduction of some wall thickness reaches 20 ~ 30.For the inspection of this kind of problem, with the general calipers and other measuring tools are often difficult to find, at this time only the use of ultrasonic thickness gauge can be detected.
The problem of excessive hardness is mainly caused by the heat treatment process after forming. The solution is to conduct another heat treatment with the correct heat treatment process, which can generally be solved after treatment.
This kind of problem has the biggest harm to the safety of the device, and it is troublesome to check.There are many and complicated factors that cause defects, which are not only the defects of the material itself but also the defects caused by the processing and manufacturing process problems and the incorrect heat treatment process.
