poeppelmann hose connectors Germany poeppelmann models poeppelmann prices

poeppelmann hose connectors are components used to connect hoses to other hoses or components. Hoses include stainless steel hoses, metal hoses, corrugated hoses, rubber hoses, plastic hoses, and other types. Different types of hose connectors vary. The materials for metal hose connectors mainly include stainless steel, nickel-plated copper, and zinc alloy. The shapes mainly include external thread end connectors, external thread 45-degree elbows, external thread 90-degree elbows, internal thread connectors, self-locking connectors, and compression ring connectors. Metal hose connectors can be selected based on installation conditions and operating environments.

poeppelmann hose connector 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. In the disconnected state, a vacuum level of 1.3×10Pa can be maintained. Precautions for use: Do not exceed the maximum operating pressure limit during use. Do not use outside the specified temperature range to prevent wear or leakage of sealing materials. Do not subject to artificial impact, bending, or stretching to prevent damage. Do not connect or disconnect under pressure or residual pressure. Do not disassemble. Use sealing materials for external pipe threads. Do not subject to artificial impact, bending, or stretching to prevent damage. Do not use with fluids other than the applicable fluid. Do not use for purposes other than quick connectors. Do not connect with quick fluid connectors from other manufacturers. Do not use in environments contaminated with metal powder, sand, or dust to prevent malfunction or leakage. Attachment of debris may cause malfunction or leakage. A brake valve must be installed before the quick connector. Do not use as a hinge connector. Use in machines with vibration or shock will reduce durability. Cold water and warm oil type: Mainly used for general-purpose mold interfaces. Fully simplifies mold exchange operations, enhances rust prevention, and offers various types. 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 specified temperature range to prevent wear or leakage of sealing materials. Do not subject to artificial impact, bending, or stretching to prevent damage. Do not use in environments contaminated with metal powder, sand, or dust to prevent malfunction or leakage. For threaded installations, do not exceed the maximum tightening torque during installation to prevent damage. Do not use cracked hoses to prevent leakage or detachment. Use in machines with vibration or shock will reduce durability. The working fluid must be clean fluid filtered through a filter. Do not disassemble quick connectors. Semiconductor type: Mainly used for semiconductor and fluororesin semiconductor production equipment and devices. The body material should be corrosion-resistant metal or all-resin products made of molded fluororesin (PFA). Precautions for use: Note: Perform dissolution tests of sealing materials with the fluid to confirm material suitability. 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 connector (the folded part of the "O"-shaped seal ring). During disconnection, since a small amount of fluid may leak out, compressed air can be used to discharge the fluid inside the quick connector before separation to prevent hazards. Do not use as a hinge connector. Do not use for purposes other than quick fluid connectors. Do not subject to artificial impact, bending, or stretching to prevent damage. Do not pressurize sleeves or quick connectors individually to prevent the valve from flying out. When used individually, the specified dust cover must be installed. Do not disassemble quick connectors.

poeppelmann hose connector features

1. Since most pipe fittings are used for welding, to improve weld quality, the ends are machined with bevels at a specific angle and with a specified land. This requirement is strict, with regulations on land thickness, angle, and tolerance range. Surface quality and mechanical properties are basically the same as those of the pipes. To facilitate welding, the steel grade of the pipe fittings is the same as that of the connected pipes. 2. All pipe fittings must undergo surface treatment, where oxide scale on the inner and outer surfaces is removed by shot blasting, followed by the application of anti-corrosion paint. This is required for export purposes; furthermore, in the domestic market, this process is also carried out to prevent rust and oxidation during transportation. 3. Regarding packaging requirements: for small pipe fittings intended for export, wooden crates are required, with a volume of approximately 1 cubic meters. It is stipulated that the quantity of elbows in such crates must not exceed one ton. The standard allows nesting (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.

poeppelmann hose connector installation

Cut the pipe to the required length using a sawing machine or specialized pipe cutting equipment. Flame cutting or grinding wheel cutting is strictly prohibited. Remove burrs, metal chips, and dirt from the inner and outer circles of the pipe end. Remove rust preventive agents and dirt from the pipe connector. Ensure the roundness of the pipe. Slide the nut and compression ring onto the pipe in sequence. The cutting edge (small diameter end) of the compression ring front should be at least 3mm from the pipe end. Then insert the pipe into the tapered hole of the connector body until it bottoms out. Slowly tighten the nut while rotating the pipe until it stops moving, then tighten the nut an additional 2/3 to 4/3 turns. Disassemble to check if the compression ring has cut into the pipe and if the position is correct. The compression ring must not move axially but may rotate slightly. After passing inspection, retighten the nut.
