Stainless steel by order, also often referred to as stainless steel ferrule fittings or stainless steel pipe fittings, is an important tubing used to connect stainless steel piping. The following is a detailed introduction about it:
Structure and principle
Stainless steel fittings are mainly composed of three parts: fitting body, ferrule and nut. One end of the fitting body is connected to the pipe, and the other end is connected to another pipe or equipment through the nut and ferrule. The ferrule is an annular metal part with taper, when the nut is tightened, the ferrule is squeezed between the joint body and the nut, and its taper will make the ferrule radially contracted, so as to hold the pipe tightly and realize the function of sealing and connection.
Characteristics
Reliable connection: through the extrusion of the ferrule, it can form a tight connection with the pipeline, effectively preventing the leakage of the medium, with good sealing performance, and can adapt to different pressures and temperatures of the working environment.
Convenient installation: no need for welding or other complex processes during installation, just insert the pipe into the joint body and tighten the nut to complete the connection, greatly improving the installation efficiency and reducing the installation cost, especially suitable for rapid on-site installation and maintenance.
Corrosion resistance: due to the use of stainless steel, it has excellent corrosion resistance, can resist the erosion of various chemical media, and is suitable for piping systems conveying corrosive liquids, gases and other media, such as chemical, petroleum, pharmaceutical and other industries.
Reusable: In the case of needing to disassemble and reconnect, as long as the ferrule and pipeline are not damaged, stainless steel by order can be reused many times, saving the cost of fittings replacement.
Good anti-vibration performance: the ferrule connection can absorb the vibration and displacement of the pipeline to a certain extent, reducing the risk of loosening and leakage of the pipeline connection parts caused by vibration, suitable for pipeline systems with vibration requirements, such as the connection pipeline of machinery and equipment.
Application Areas
Industrial piping system: Widely used in the piping system of chemical industry, petroleum, natural gas, pharmaceutical, food and beverage and other industrial fields, used to connect all kinds of pipelines for transporting liquids, gases and powders, to ensure the safe and reliable operation of piping system.
Hydraulic and pneumatic system: in hydraulic and pneumatic equipment, stainless steel by the order used to connect hydraulic oil pipe and pneumatic air pipe, can withstand high pressure, to ensure the stability of the hydraulic and pneumatic system work.
Instrumentation connection: in the pipeline connection of instrumentation, stainless steel by the order of its high-precision connection and good sealing performance, to ensure the accuracy and stability of instrumentation measurement, widely used in a variety of industrial automation control systems.
Refrigeration and air-conditioning system: in the pipeline connection of refrigeration and air-conditioning system, stainless steel by order can adapt to the working environment of low temperature and high pressure, prevent the refrigerant leakage, and ensure the cooling and heating effect of the system.
Selection considerations
Size: According to the outer diameter and wall thickness of the connected pipeline, select the appropriate specification of stainless steel fittings to ensure that the fittings and pipelines can be a close fit.
Pressure level: According to the working pressure of the pipeline system, select the corresponding pressure level of the order, in order to ensure the safe and reliable operation under the working pressure.
Material selection: according to the nature of the pipeline conveying medium and the working environment, select the appropriate stainless steel material. Common 304 stainless steel and 316 stainless steel, 316 stainless steel corrosion resistance is better, suitable for more severe working environment.
Connection: Stainless steel by order has a variety of connection methods, such as straight, elbow, tee, etc., according to the layout of the piping system and connection requirements, choose the appropriate connection method.
