SF-FILTER hose fittings, German SF-FILTER models, SF-FILTER prices

SF-FILTER hose fittings are widely used in high-pressure piping applications in industrial fields, such as shipbuilding, offshore oil, metal processing, and mining. Flared tube fittings are suitable for hydraulic, lubrication, high-pressure water flushing, and high-pressure air pipelines. Flared tube fittings have been certified by many auditing bodies; they offer high reliability, inherent cleanliness, and strong flexibility, with faster and simpler pre-processing assembly and installation. The flared connection requires no welding, saving subsequent processes such as pickling and flaw detection. Flared tube fittings are a type of quick-connect fitting suitable for various pipe fittings and pipes with nominal pressures not exceeding 32MPa. Introduction to flared connection manufacturers: widely used in industries such as oil refining, chemical engineering, light industry, textiles, national defense, metallurgy, aviation, automotive, pharmaceuticals, machinery, shipbuilding, natural gas, and CNG refueling stations.

SF-FILTER hose fitting classification

For both gas and liquid, mainly used for piping in ion cooling devices, brewing equipment, cutting oil piping for machine tools, and car wash machines. Connected via simple lever operation, it can transport liquids, gases, powders, etc. There is a wide variety of body materials, sizes, and installation shapes. Precautions for use: Do not use with fluids other than the applicable fluid. Do not exceed the maximum operating pressure during use. Do not use outside the operating temperature range to prevent wear or leakage of sealing materials. Do not disassemble; use sealing material for external threads of pipe threads. During installation, do not exceed the maximum torque to prevent damage. Do not use for purposes other than quick-connect fittings. Do not connect with quick fluid connectors from other companies. Do not artificially strike, bend, or stretch to prevent damage. Do not use in places mixed with metal powder or sand/dust to prevent malfunction or leakage. Attachment of debris will cause malfunction or leakage. A brake valve must be installed before the quick connector. Do not use as a hinged joint. Use on machines with vibration or impact will reduce durability. For steel and iron quick connectors, do not use water or glycol-based media, as the zinc coating on the surface will dissolve. The working fluid must be clean fluid filtered through a filter. When using "O" seals, they must always remain in an oiled state. For hydraulic types, the body material should be metal resistant to vibration and impact. There is a wide variety of sizes and installation shapes. Precautions for use: Do not use with fluids other than the applicable fluid. Do not exceed the maximum operating pressure limit of the quick-change connector during use. Do not use outside the operating temperature range to prevent wear or leakage of sealing materials. Do not disassemble when hydraulic pressure is present; use thread-specific sealing material for the external threads of pipe threads. During installation, do not exceed the maximum torque to prevent damage. Do not use for purposes other than quick-connect fittings. Do not connect with quick fluid connectors from other companies. Do not artificially strike, bend, or stretch to prevent damage. Do not use in places mixed with metal powder or sand/dust to prevent malfunction or leakage. Attachment of debris will cause malfunction or leakage. A brake valve must be installed before the quick connector. Do not use as a hinged joint. Use on machines with vibration or impact will reduce durability. Do not use water or glycol-based media. Such substances will cause the surface zinc coating to dissolve. The working fluid must be clean fluid filtered through a filter. When using "O" seals, they must always remain in an oiled state. The flow velocity of the fluid during use should be kept below 8m/s. Refer to the end of these precautions to confirm the sealing material and body material suitable for the working fluid.

SF-FILTER hose fitting selection criteria

1, fluid type, and temperature (please select quick connectors with body and sealing materials suitable for the fluid type and temperature). Depending on the fluid, the suitable body and sealing materials differ. For example, for air, steel-made quick connectors are recommended; for water, choose brass or stainless steel. 2, liquid pressure (please select quick connectors with pressure resistance suitable for the fluid pressure). Fluid pressure is also key to selecting quick connectors. Hydraulic quick connectors are serialized between 5.0Mpa (51kgf/cm&²) and 68.6Mpa (700kgf/cm&²); corresponding to pressure resistance characteristics, the structure of quick connectors also differs. 3, automatic shut-off valve structure (please select quick connectors with valve structures suitable for piping applications). Regarding valve structures, there are two-way shut-off, one-way shut-off, and two-way open types. Note that except for the two-way shut-off type, fluid flows out from the piping upon separation. 4, usage environment of the quick connector (please select quick connectors with structures and materials suitable for the usage environment). Consider the humidity conditions, dust status, and corrosive nature of the usage environment when selecting the type, body material, and sealing material of the quick connector. 5, ensure the connection threads of the selected quick connector are consistent. When using products from different brands, it is best to use male and female ends from the same brand. If cross-use is necessary, consult the supplier's technical personnel beforehand to confirm compatibility before use. 6, installation shape and dimensions. Determine the model and material of the quick connector, and specify the assembly shape and dimensions corresponding to the piping characteristics. Note that dimensions are related to fluid flow rate.

SF-FILTER hose fitting material classification

Malleable iron tee. The manufacturing material and specification range of malleable iron tees are the same as those of malleable iron elbows (please refer to the aforementioned introduction to malleable iron elbows), mainly used for indoor heating, water supply/drainage, and gas pipelines. Cast iron tee. Like cast iron elbows, cast iron tees are cast from gray cast iron, with commonly used specifications and pressure ranges being the same. According to different connection methods, they are divided into socket cast iron tees and flange cast iron tees. Socket cast iron tees are mainly used for water supply and drainage pipelines; water supply pipelines mostly adopt 90° straight tees; drainage pipelines usually adopt 45° angled tees to reduce fluid resistance and prevent pipeline blockage. Flange cast iron tees are generally 90° straight tees, mostly used for outdoor cast iron pipes. Steel tee. Standardized tees are usually made using molds, undergoing processes such as blanking, hole punching, and heating, then machined from medium/low-pressure steel to form tees, which are welded during on-site installation. There are two cases for tees used in steel plate rolled pipes: one is blanked from steel plates at the processing plant and formed by rolling and welding; the other is hole-punched and connected during on-site installation.
