bielomatik hose fittings Germany bielomatik model bielomatik price

bielomatik hose fittings are straight-through connectors used for linear connections such as instruments. Connection methods include socket welding or threaded connection. They are mainly used for small-diameter, low-pressure pipelines, for parts that require frequent assembly and disassembly, or for final adjustment of pipelines using threaded fittings. Relevant products are all listed in Kuaiyiyou. The structural design should preferably adopt a metal-to-metal contact sealing structure. Gasket sealing structures are generally used in general pipelines transporting water, oil, air, etc., and are made of malleable cast iron. In addition, application requirements and quotation are also factors to consider when selecting. There are many types of hose straight-through connectors. Commonly used hose straight-through connectors can generally be divided into hard hose straight-through connectors and soft hose straight-through connectors. If classified according to the connection method between the hose straight-through connector and the pipeline, hard hose straight-through connectors come in three types: flared, ferrule-type, and welded. Soft hose straight-through connectors are mainly crimped rubber hose straight-through connectors. The connection methods between pipelines and hose straight-through connectors in hydraulic systems also differ. The pipe insertion end uses connecting threads. Tapered threads rely on their conical body to tighten and use materials such as polytetrafluoroethylene for sealing operations. They are mainly used in medium and low-pressure hydraulic systems.

bielomatik hose fitting classification

Inert gas type, mainly used for vacuum piping and compressor pressure resistance tests. Both the sleeve and plug have built-in automatic shut-off valves suitable for vacuum applications, which can maintain a vacuum degree of 1.3×10Pa in the disconnected state. Precautions for use: Do not exceed the maximum operating pressure limit during use. Do not use outside the operating temperature range to prevent wear or leakage of sealing materials. Do not artificially strike, bend, or stretch to prevent damage. Do not connect or disconnect under pressure or residual pressure. Do not disassemble. Please use sealing materials for external pipe threads. Do not artificially strike, bend, or stretch to prevent damage. Do not use with fluids other than the applicable fluid. Do not use for purposes other than quick couplings. Do not connect with quick fluid couplings from other manufacturers. 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 coupling. Do not use as a hinge joint. Use in machines with vibration or impact will reduce durability. Cold water/warm oil type, mainly used for general-purpose mold interfaces. Completely simplifies mold exchange operations, enhances rust prevention functions, and offers a wide variety. Precautions for use: Note, do not use with fluids other than the applicable fluid. Do not exceed the maximum operating pressure limit during use. Do not use outside the operating temperature range to prevent wear or leakage of sealing materials. 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. For threaded installation, do not exceed the maximum tightening torque during installation to prevent damage. Do not use hoses with cracks to prevent leakage or detachment. Use in machines with vibration or impact will reduce durability. The working fluid must be clean fluid filtered through a filter. Do not disassemble the quick coupling. Semiconductor type, mainly used for semiconductor and fluororesin semiconductor production equipment and devices. The main body material should be corrosion-resistant metal or molded fluororesin (PFA) all-resin products. Precautions for use: Note, conduct dissolution tests of sealing materials with the fluid to confirm whether the material is suitable. Please use Teflon sealing tape for external pipe threads. Do not exceed the maximum tightening torque when installing threads to prevent damage. To reduce friction (insertion load) and protect the "O"-shaped seal ring during insertion, apply the working fluid or pure water to the "O"-shaped seal ring or the quick coupling (the folded part of the "O"-shaped seal ring). During separation, since a small amount of fluid flows out, compressed air can be used to discharge the fluid inside the quick coupling before separation to prevent danger. Do not use as a hinge joint. Do not use for purposes other than quick fluid couplings. Do not artificially strike, bend, or stretch to prevent damage. Do not pressurize when using sleeves or quick couplings individually to prevent the valve from flying out. When used individually, the specified dust cap must be installed. Do not disassemble the quick coupling.

bielomatik hose fitting differences

Difference between external water pipe fittings and union joints: Unions are used to connect pipes. Quick-install fittings have one end that can connect to a pipe and the other end that can connect to a hose for easy material discharge. They can also be covered with a cap when not in use. When installing water pipe fittings, you must first understand the original components of the water pipe fitting. The components of water pipe fittings include: elbows, reducing elbows, internal/external thread elbows, tees, reducing tees, internal thread fittings, reducing internal thread fittings, external thread fittings, internal/external thread fittings (bushings), caps, plugs, union joints, etc. If you choose PPR pipes, simply weld them with a hot melt machine; if using iron pipes, you need to thread them with a threading machine first, then wrap with hemp yarn or raw material tape.

bielomatik hose fitting cleaning

To ensure the cleanliness of the lubrication system and supply clean grease to the bearings of mechanical equipment, the pre-installed pipelines must be removed and cleaned. Cleaning methods include kerosene cleaning and acid pickling. Objects and methods for kerosene cleaning: copper pipes, stainless steel pipes; steel pipes that have undergone acid pickling treatment before pre-installation and have no rust or iron oxide scale on the inner wall; pipe fittings dirtied during pre-installation. Remove the pipes and fittings that need cleaning. Wipe the inside of the pipes clean with a cloth dipped in kerosene. Soak both ends and fittings in kerosene for cleaning. Then coat the inside of the pipes with engine oil or fill with grease, and seal both ends tightly for installation. There must be no visually visible contaminants after cleaning. Pay special attention to thoroughly cleaning the welding slag on the inner wall of the welds. During disassembly, transportation, and acid pickling, take care not to damage the pipelines, threads, and sealing surfaces. Seal the openings with tape or plastic tubes. Threaded parts should be protected with acid-resistant materials such as plastic tape or rubber tape, or coated with dry oil at the threads after degreasing and water washing before rust removal in acid solution to prevent acid erosion. During acid pickling, take care not to let the matching marks on the pipes disappear or become blurred.
