NORGREN hose fittings Germany NORGREN model NORGREN price

NORGREN hose fitting is a type of hose fitting mainly composed of three components. Metal hose fittings are used in many applications. The main component of the metal hose fitting, the bendable part, is made of braided metal wire. Metal hose fittings offer excellent performance and come in a wide variety. Different types of metal hose fittings have different characteristics, structures, and maximum temperature ratings.

NORGREN hose fitting features

1. Since most pipe fittings are used for welding, to improve welding quality, the ends are machined with bevels, leaving a certain angle and edge. This requirement is strict; there are regulations for edge thickness, angle, and tolerance range. Surface quality and mechanical properties are basically the same as the pipe. To facilitate welding, the steel grade of the pipe fittings is the same as that of the connected pipes. 2. All pipe fittings undergo surface treatment; oxide scale on the inner and outer surfaces is removed by shot blasting, followed by application of anti-corrosion paint. This is required for export purposes. Domestically, this is also done to facilitate transportation and prevent rust and oxidation. 3. Packaging requirements: For small pipe fittings, such as for export, wooden crates are required, approximately 1 cubic meters. It is specified that the quantity of elbows in such crates must not exceed one ton. Nesting is allowed under this standard (i.e., smaller fittings inside larger ones), but the total weight generally must not exceed 1 tons. For large items y, individual packaging is required; for example, 24″ fittings must be packaged individually. Additionally, packaging marks must indicate dimensions, steel grade, batch number, manufacturer trademark, etc.

NORGREN hose fitting precautions

Three-way water pipe connector, solution for quick-connect water pipe fittings. This process is very fast. Many friends may not be particularly familiar with high-pressure quick-connect water pipe fittings. In fact, this type of water pipe is quickly connected in faucets, spray guns, and water pipelines. This method is labor-saving and especially convenient. The method for quick connection of high-pressure water pipe fittings is as follows: First, install quick connectors on both ends of the water pipe, and gently tighten the adjacent nuts. Next, connect to the faucet connector or use the spray gun connector. If you hear a "click" during this process, it indicates that the high-pressure water pipe quick connector has been successfully connected. Closed-type water pipe connector method: When the mold connector and mold water nozzle in the high-pressure water pipe quick connector are closed, the female and male heads block the fluid channel under the force of their respective pins and springs when not connected. The pins of both the male and female heads close, instantly blocking fluid flow. When in the connected state, as the male head is inserted into the female head, the pins return to their original positions under spring action. Steel balls roll to lock, ensuring a tight connection between the male and female heads. Simultaneously, the pins of the female and male heads push each other open, allowing fluid flow. The O ring in the high-pressure water pipe quick connector can completely prevent fluid leakage.

NORGREN hose fitting classification

Different names for the same type of pipe fitting. To remember easily: Internal connector has external threads; external connector has internal threads. Threaded connectors are generally used for pipelines to provide connection. External thread refers to threads on the outside of pipes, etc., which can generally be touched directly. Internal thread refers to threads inside pipes, etc., which generally require reaching inside to touch. In industry, you may also encounter right-hand threads and left-hand threads. Right-hand thread: Threads that tighten in the clockwise direction (righty-tighty). This type of thread is common in daily life, with screws being the most common example. Left-hand thread: Threads that must be turned in the reverse direction to tighten. This type of thread is not very common in daily life but is seen more often in specialized fields, such as ventilation.
