IFM hose fittings Germany IFM model IFM price

IFM hose fittings are components in hydraulic systems that connect high-pressure oil hoses to other high-pressure oil hoses. Hydraulic pipe fittings can be further classified into hydraulic hoses, high-pressure ball valves, quick couplings, compression-type pipe fittings, welded pipe fittings, high-pressure hoses, transition-type pipe fittings, tee-type pipe fittings, non-standard pipe fittings, flared-type pipe fittings, right-angle pipe fittings, rotary pipe fittings, quick couplings, stainless steel pipe fittings, and copper fittings.

IFM hose fitting selection

Metal hose fittings are widely used in industrial piping systems; they are also a type of high-quality flexible piping. They mainly consist of bellows, wire braiding, and fittings, offering advantages such as novel structure, stable performance, and high reliability. 1, installation shape and dimensions: determine the model and material of the quick coupling, and specify the assembly shape and dimensions corresponding to the piping characteristics. 2, operating environment of the quick hose coupling: consider the humidity conditions, dust levels, and potential corrosion in the operating environment to select the type of quick coupling, body material, and sealing material. 3, fluid pressure: fluid pressure is also a key factor in selecting quick couplings. 4, construction of automatic shut-off valves: valve constructions include two-way shut-off type, single-way shut-off type, and two-way open type. 5, fluid type and temperature: suitable body materials and sealing materials vary depending on the fluid. Steel is recommended; for water, choose brass or stainless steel. Note that except for the two-way shut-off type, fluid may leak from the piping during disconnection.

IFM hose fitting selection

Unidirectional flow type: Rotary joints are installed at both ends of the drum; fluid enters from one end and exits from the other, without using an inner tube. Unidirectional flow type: A rotary joint is installed at one end of the drum, where fluid is both introduced and discharged; the inner tube remains stationary relative to the rotation of the drum. Bidirectional flow type (fixed inner tube): Unlike the previous type, this version uses different types of siphon tubes inside the drum to discharge condensate; this type is mostly used for steam applications. Bidirectional flow type (rotating inner tube): This type features a structure where the inner tube is fixed relative to the drum and rotates synchronously with it; in this case, fluid is introduced through the inner tube and discharged through the outer tube. Bidirectional flow type (rotating inner tube): A siphon device rotating synchronously with the drum is installed inside the drum to discharge condensate; this type is mostly used for steam applications.

IFM hose fitting manufacturing key points

Stainless steel elbows: 1, keep welding electrodes dry during use. Titanium-calcium type electrodes should be dried at 150℃ for 1 hour, and low-hydrogen type electrodes should be dried at 200-250℃ for 1 hours (do not repeatedly re-dry, otherwise the coating may crack and peel). Prevent the electrode coating from adhering to oil and other contaminants to avoid increasing carbon content in the weld and affecting weld quality. During elbow welding, repeated heating causes carbide precipitation, reducing corrosion resistance and mechanical properties. Post-weld hardening is significant, making cracks likely. If welding with similar types of electrodes, preheating above 300℃ and slow cooling to around 700℃ after welding are required. If post-weld heat treatment is not possible for the weldment, chromium-nickel stainless steel electrodes should be selected. 2, to improve the corrosion resistance and weldability of stainless steel elbows, appropriate amounts of stabilizing elements such as Ti, Nb, and Mo are added, resulting in better weldability. When using similar chromium stainless steel electrodes, preheating above 200℃ and tempering at around 800℃ after welding are required. If heat treatment is not possible for the weldment, chromium-nickel stainless steel electrodes should be selected.
