Tube fittings: a key element in connecting industry to life
In today's modern industrial and construction fields, pipe fittings as a basic component, although often unnoticed by the general public, but plays an important and indispensable role. Whether it is to transport various types of fluid media, or to build complex piping systems, pipe fittings are to ensure the stable operation of the entire system is a key link.
1. The types and characteristics of fittings
There are various types of pipe fittings to meet the specific needs of different scenarios. Among them, elbows are commonly used to change the direction of pipeline flow, and their bending angle can precisely guide the fluid to be transmitted in accordance with a predetermined route, and there are common 90-degree elbows and 45-degree elbows. Tee is mainly used to realize the function of pipe diversion or merging, in the complex pipeline network, it can be a main pipeline fluid distribution to a number of branch pipelines, or a number of branch pipeline fluid convergence together. Reducer, as the name suggests, can connect pipes of different diameters, effectively solving the connection problems brought about by changes in pipe diameter and guaranteeing the smooth transition of fluids between pipes of different diameters.
These fittings also have their own characteristics in terms of material, common materials include metal materials such as carbon steel, stainless steel, etc., as well as non-metallic materials such as PVC (polyvinyl chloride), PPR (random copolymerized polypropylene) and so on. Metal fittings usually have high strength and pressure resistance, can adapt to high temperature, high pressure and other harsh working environment, such as in the petrochemical industry, a large number of high-temperature and high-pressure fluid transportation pipeline are dependent on metal fittings to build a reliable transmission line. Non-metallic fittings have light weight, corrosion resistance, low cost and other advantages, in the building water supply and drainage systems and some normal temperature and pressure fluid transportation scenes have been widely used. pvc fittings because of its good chemical stability, in the family water pipeline installation is used in large quantities; PPR fittings are characterized by its high temperature resistance, in the hot water supply system excels.
2. The important application of pipe fittings in the industrial field
In the huge system of industrial production, the application of pipe fittings is almost everywhere. In the petrochemical industry, pipe fittings bear the heavy responsibility of conveying crude oil, natural gas, various chemical raw materials and finished products. These media are often corrosive, flammable and explosive, high temperature and high pressure and other dangerous characteristics, the quality and performance of the pipe fittings put forward extremely stringent requirements. Once the pipe fittings leakage or failure, may cause serious safety accidents, resulting in production interruption, bringing huge economic losses to the enterprise, and even to the surrounding environment and personnel life safety pose a serious threat. Therefore, petrochemical companies in the selection, procurement and installation of pipe fittings in the process, need to strictly follow the relevant standards and norms, the pipe fittings for strict quality testing and monitoring.
The electric power industry is also one of the important application areas of the pipe fittings. In the thermal power generation process, a large number of steam, water and other media need to be circulated and transmitted through the piping system. Pipe fittings in which not only to ensure the efficient transportation of media, but also have good heat resistance and sealing performance to ensure the normal operation of power generation equipment. In nuclear power plants, pipe fittings are even more critical components for nuclear safety. As the medium in the nuclear reactor is radioactive, the quality and reliability of the pipe fittings are directly related to the safe and stable operation of the nuclear facilities as well as the radiation safety of the surrounding environment and personnel. Therefore, the nuclear power plant on the pipe fittings material, manufacturing process, testing standards have very high requirements, from the procurement of raw materials to the final installation of the pipe fittings to use, each link has to undergo strict quality control and safety review.
3. The extensive use of pipe fittings in the construction field
In the construction industry, pipe fittings are the core components of the water supply and drainage system, heating system and fire protection system. In the water supply and drainage system, the pipe fittings connect the water source with the various water points in the building to ensure the stable supply of domestic water and the effective discharge of sewage. High-quality fittings can effectively prevent the occurrence of water leakage phenomenon, to avoid wall dampness, mold and other problems caused by pipe leakage, to protect the structural safety of the building and interior decoration. In the heating system, the fittings are responsible for the transmission of hot water or steam, so that the indoor can maintain a comfortable temperature. Their good insulation and sealing properties help to reduce heat loss and improve the energy efficiency of the heating system.
Fittings in fire protection systems are even more critical elements for the safety of life and property. In the event of a fire, fire piping fittings must be able to withstand the impact of high-pressure water flow to ensure that the fire water can be quickly and accurately transported to the fire scene of the nozzle to extinguish the fire in a timely manner. Therefore, the fire fittings need to have high strength, high pressure, corrosion resistance and other properties, and to be regularly checked and maintained to ensure that at the critical moment can work properly.
