zimmerlin hose connectors Germany zimmerlin model zimmerlin price

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

zimmerlin hose connector installation notes

Pipe threads must meet requirements; threading should be completed in two passes. Coolant must be used during machining. Machine threads to standard specified dimensions. Clean off chips remaining on the threads or pipe ends. Apply rust inhibitor to the thread surface for corrosion protection and sealing. The engagement length of the threaded connection should be tightened with a pipe wrench to adjust torque. After connecting the pipe and fittings, apply rust-proof sealant or zinc-rich paint to exposed threads, clamp marks, and surface damage. Do not install backwards when threaded connector heights differ. Locking methods must be reliable. For bolt structures subject to bending moments, minimize thread loading to avoid bending stress on the bolt. Threaded holes should not pass through two welded parts. For deep threaded holes, design corresponding bosses on the part. The heads of fastening bolts for high-speed rotating bodies should not protrude.

zimmerlin hose connector classification

Bite-type pipe fittings: The bite-type fitting works by inserting the steel pipe into the ferrule and tightening the ferrule nut, which presses against the ferrule and cuts into the pipe to create a seal. No welding is required for connection to steel pipes, which aids in fire prevention, explosion protection, and high-altitude work, and eliminates drawbacks from improper welding. Therefore, it is a relatively advanced connector used in piping systems for automatic control devices in oil refining, chemical, petroleum, natural gas, food, pharmaceutical, and instrumentation systems. It is suitable for connecting pipelines carrying oil, gas, water, and other media. Bite-type fittings feature reliable connection, high pressure resistance, temperature resistance, good sealing, good repeatability, easy installation and maintenance, and safe and reliable operation. Flared pipe fittings: Flared pipe fittings are suitable for media such as oil, water, and gas (non-corrosive or corrosive). Requirements for matching steel pipe specifications are flexible. After welding to the pipeline, they offer reliable connection and good sealing performance. Thus, they are widely used in oil refining, chemical, light industry, textile, national defense, metallurgy, aviation, and shipbuilding systems, as well as in hydraulic transmission lines for various mechanical engineering and machine tool equipment. Welded pipe fittings: Welded pipe fittings are suitable for media such as oil, water, and gas (non-corrosive or corrosive). For welded sealed pipe fittings, requirements for matching steel pipe specifications are flexible. After welding to the pipeline, they offer reliable connection and good sealing performance. Thus, they are widely used in oil refining, chemical, light industry, textile, national defense, metallurgy, aviation, and shipbuilding systems, as well as in hydraulic transmission lines for various mechanical engineering and machine tool equipment. When production of bite-type pipe fittings cannot meet demand, or in highly corrosive environments, their use should be prioritized.

zimmerlin hose connector features

1, Since most pipe fittings are used for welding, to improve welding quality, the ends are machined with bevels, leaving a specific angle and edge. This requirement is strict, with regulations on 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 fittings is the same as that of the connected pipes. 2, All pipe fittings undergo surface treatment, where 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 and also done domestically to prevent rust and oxidation during transportation. 3, Packaging requirements: For small fittings, such as for export, wooden crates are required, approximately 1 cubic meters in volume. Regulations state that the quantity of elbows in such crates must not exceed one ton. Nesting is allowed under this standard (i.e., smaller items inside larger ones), but the total weight generally must not exceed 1 tons. For large items y, individual packaging is required; for example, 24″ items must be packaged individually. Additionally, packaging markings must indicate dimensions, steel grade, batch number, manufacturer trademark, etc.
