WEH hose connectors, Germany WEH models, WEH prices

WEH hose connectors: In piping systems, elbows are fittings that change the direction of the pipeline. Classified by angle, the three most common types are 45° and 90°180°. Additionally, based on engineering requirements, other non-standard angle elbows such as 60° are included. Elbow materials include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals, and plastics. Connection methods to pipes include: direct welding (the most common method), flange connection, hot melt connection, electrofusion connection, threaded connection, and socket connection. According to production processes, they can be divided into: welded elbows, stamped elbows, push-formed elbows, cast elbows, butt-weld elbows, etc. Other names: 90 degree elbow, right-angle elbow, etc.

WEH hose connector crimping

How to crimp high-pressure pipe connectors: First is the international metric internal thread flat-face connector; second is the international metric bite-type connector; third is the international metric internal thread 74 degree internal cone face connector; fourth is the international metric internal thread spherical connector; fifth is the mining hydraulic support connector. Precautions for using high-pressure oil pipe connectors: 1. When handling high-pressure oil pipes, ensure no external friction occurs to avoid damage. Although hoses are consumable, prevent leakage from the exterior of the high-pressure oil pipe. 2. Do not bend high-pressure oil pipes, as this causes internal damage and creates unnecessary trouble for future use. 3. Do not use high-pressure oil pipes immediately; it is recommended to filter with water first. Some high-pressure oil pipes are acid and alkali resistant; do not test with liquids that conflict with the current fluid. 4. Tighten high-pressure oil pipe connectors securely during installation to prevent fluid leakage.

WEH hose connector classification

Inert gas type: Mainly used for vacuum piping and compressor pressure tests. Both sleeves and plugs have built-in automatic shut-off valves suitable for vacuum applications, maintaining a vacuum level of 1.3×10Pa in the disconnected state. Precautions: Do not exceed the maximum operating pressure limit. Do not use outside the operating temperature range to prevent seal wear or leakage. 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 material for external threads of 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 with metal powder or sand/dust to prevent malfunction or leakage. Debris attachment causes malfunction or leakage. A brake valve must be installed before the quick connector. Do not use as a hinge joint. Use in machines with vibration or shock reduces durability. Cold/hot water and oil type: Mainly used for general-purpose mold interfaces. Simplifies mold exchange operations, enhances rust prevention, and offers diverse types. Precautions: Do not use with fluids other than the applicable fluid. Do not exceed the maximum operating pressure limit. Do not use outside the operating temperature range to prevent seal wear or leakage. Do not subject to artificial impact, bending, or stretching to prevent damage. Do not use in environments with metal powder or sand/dust to prevent malfunction or leakage. For threaded installations, do not exceed the maximum tightening torque to prevent damage. Do not use cracked hoses to prevent leakage or detachment. Use in machines with vibration or shock reduces durability. The working fluid must be clean and filtered. Do not disassemble quick connectors. Semiconductor type: Mainly used for semiconductor and fluororesin semiconductor production equipment. The body material should be corrosion-resistant metal or molded fluororesin (PFA) all-resin products. Precautions: Conduct leaching tests of sealing materials with the fluid to confirm suitability. Use Teflon sealing tape for external threads of pipe threads. Do not exceed the maximum tightening torque during thread installation to prevent damage. To reduce friction (insertion load) and protect the "O" ring seal during insertion, apply the working fluid or pure water to the "O" ring seal or quick connector (folded part of the "O" ring seal). During separation, a small amount of fluid flows out; to prevent danger, use compressed air to discharge the fluid inside the quick connector before separation. Do not use as a hinge joint. 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 connector units alone to prevent valve ejection. Install specified dust caps when used as single units. Do not disassemble quick connectors.
