Union, also called union or union, is a common pipe connection that can be easily installed and disassembled. It must be composed of three parts: nut, cloud head and flat connection. Pipe connectors are machined after forging of round steel or steel ingots. Its connection forms are divided into socket welding and threaded connection. Socket welding is to insert the steel pipe into the socket hole for welding. Therefore, it is called "socket welding". "Union", threaded connection is to screw the steel pipe into the screw hole for connection, therefore, it is called "threaded union", the main manufacturing standards are ASMEB16.11, MSSSP83. The types of socket unions include equal diameter and different diameter. The socket union is composed of a socket, a socket, a socket groove, etc. It is characterized in that there is a socket groove on the socket, and the socket and socket are located at both ends respectively; compared with the existing technology, it is reasonably designed, simple to operate and practical. Strong performance, improves operation quality and convenience. Socket unions can be widely used in pipes of different diameters, and can also be used in water meters and valves. Due to the socket structure, the pipe joint reduces the cost and is extremely convenient to install, use and maintain. It also has extremely high leakage prevention capabilities and has great market prospects. A quick connector is a connector that can connect or disconnect pipelines without tools. Quick connectors can be divided into: quick connectors for air, quick connectors for oxygen and fuel gas, quick connectors for gas and liquid pressure, quick connectors for oil pressure, quick connectors for inert gas, quick connectors for cooling water temperature oil, and semiconductor quick connectors. Air type Quick connectors for air are mainly used for quick installation of air pipelines and connector accessories for pneumatic tools. Corresponding to its use, there are a variety of body materials, sizes and installation shapes. Precautions for use: Please do not use it for purposes other than fluids. Please do not use it with fluids other than applicable fluids. Do not exceed the maximum operating pressure when using it. Do not use it outside the operating temperature range to prevent deformation of the sealing material, which may easily lead to leakage. Do not hit, bend, or stretch artificially to prevent damage. Do not use it in places where metal powder or sand dust is mixed. You can use a quick connector here to use it under very harsh working conditions and ensure a long service life. If debris is attached, it may cause malfunction or leakage. ?Do not disassemble the quick connector. Gas type: Mainly used for general fuse piping, with the characteristics of large flow, durability and corrosion resistance. The main body materials, sizes and installation shapes are diverse. Precautions for use: Warning Fluid must flow from the sleeve side to the plug side. Please use sealing material for the external thread of the pipe thread. When installing threads, please do not exceed the maximum tightening torque to prevent damage. Please do not use it for purposes other than quick fluid couplings. Please do not use it with fluids other than applicable fluids. Please do not connect with quick fluid couplings made by other companies. Do not exceed the maximum operating pressure limit when using it. Do not use it outside the operating temperature range to prevent wear or leakage of the sealing material. Do not hit, bend, or stretch artificially to prevent damage. Do not use it in places where metal powder or sand dust is mixed to prevent malfunction or leakage. If debris is attached, it may cause malfunction or leakage. Please do not use it where gas accumulates. Please do not carry out loading and unloading operations when there is an open flame nearby. When tempering occurs, please replace it with a new one. When installing the hose, be sure not to get oil on it to prevent natural fires. When reinstalling the hose, cut off the end of the hose from more than 3 cm. Note: Please do not use it for purposes other than quick fluid couplings. Insert the hose firmly into the base of the interface and secure it with a hose strap or nut. To prevent moisture from being absorbed, it should be stored indoors. Do not use cracked hoses to prevent leakage and falling off. A leak check should be carried out before use. If there is leakage, stop using it immediately and replace it with a new one. Make sure the gas welding gun valve is closed before making connections. For welding products, please pay attention to safety inspection of joints and pipelines after using them for a period of time to see if there is any air leakage. Gas-liquid application: Mainly used for ion cooling device piping, brewing equipment, cutting oil piping of working machines, and car washing machines. With a simple lever-operated connection, liquids, gases, powders, etc. can be transported. The main body materials, sizes and installation shapes are diverse.
Precautions for use: Warning: Please do not use it with fluids other than applicable fluids. Do not exceed the maximum operating pressure when using it. Do not use it outside the operating temperature range to prevent wear or leakage of the sealing material. Do not disassemble. Note: Please use sealing material for the external thread of the control thread. When installing, the applied torque should not exceed the maximum torque to prevent damage. Please do not use it for purposes other than quick connectors. Please do not connect with quick fluid couplings made by other companies. Do not hit, bend, or stretch artificially to prevent damage. Do not use it in places where metal powder or sand dust is mixed to prevent malfunction or leakage. If debris is attached, it may cause malfunction or leakage. A brake valve must be installed before the quick connector. Please do not use it as a hinge joint. If used in machines with vibration and impact, the durability will be reduced. Do not use water or glycol series media for steel and iron quick connectors. The zinc coating on the surface will dissolve. The fluid used is clean fluid filtered by the filter. The "O" seal ring must always be kept in a state of oil content when used. Hydraulic type Mainly. The main body material should be made of metal that can resist vibration and impact. Various sizes and installation shapes are available.
