UNIL hose fittings Germany UNIL model UNIL price

UNIL hose fittings connect different hydraulic components to form a closed-loop hydraulic system, serving as a connecting accessory. They connect various hydraulic components (pumps, delivery lines, directional valves, shut-off valves, hydraulic motors, hydraulic cylinders, and auxiliary components such as level gauges, thermometers, and pressure gauges) to form a closed-loop hydraulic system, acting as a connecting accessory.

UNIL hose fitting material classification

1. Austenitic stainless steel: the matrix is primarily composed of austenite structure (γ phase) with a face-centered cubic lattice, non-magnetic, and strengthened mainly through cold working (which may induce some magnetism). 2. Austenitic-ferritic (duplex) stainless steel: the matrix contains both austenite and ferrite phases (with the minor phase content generally greater than 15%), is magnetic, and can be strengthened through cold working. 3. Ferritic stainless steel: the matrix is primarily composed of ferrite structure (α phase) with a body-centered cubic lattice, is magnetic, generally cannot be hardened by heat treatment, but can be slightly strengthened by cold working. 4. Martensitic stainless steel: the matrix is martensitic, is magnetic, and its mechanical properties can be adjusted through heat treatment. 5. Precipitation-hardening stainless steel: the matrix is austenitic or martensitic, and can be hardened (strengthened) through precipitation hardening (also known as age hardening). 6. Stainless steel: 1Cr18Ni9Ti 0Cr18Ni9 00Cr19Ni10 0Cr17Ni12Mo2Ti 00Cr17Ni14Mo2 304 304L 316 316L etc. 3, stainless steel elbows have certain corrosion resistance (to oxidizing acids, organic acids, cavitation), heat resistance, and wear resistance. They are typically used in equipment materials for power stations, chemical industry, and petroleum. Stainless steel elbows have poor weldability; attention should be paid to welding procedures, heat treatment conditions, and the selection of suitable welding electrodes.

UNIL hose fitting precautions

Hoses must not be excessively bent during movement or when stationary, nor bent at the root; bending should start at least at 1.5 times the diameter; hoses should not be pulled too tight when moved to extreme positions and should remain relatively slack; avoid twisting deformation of the hose as much as possible; keep hoses away from heat-radiating components, installing heat shields if necessary; avoid external damage to the hose, such as long-term friction against component surfaces during use; if the hose's own weight causes excessive deformation, supports should be provided.

UNIL hose fitting functions

Exchange function: accessories for pneumatic and hydraulic tools, cylinders, hydraulic cylinders, and metal mold-related machinery. Maintenance function: cooling devices for computers, maintenance of die-casting machine cylinders. Testing function: testing for vacuum, pressure resistance, leakage, and operation. Conveying function: transport and handling of solids such as bolts and nuts, as well as electrical conductivity. Filling function: inert gases, nitrogen, PG, carbonic acid. Connection function: fixtures for fishing rods and portable CD players, connections for mobile operations, and applications other than fluid transfer. Time and labor saving: disconnecting and connecting oil lines with quick couplings is simple, saving time and manpower. Oil saving: when oil lines are disconnected, the check valve on the quick coupling closes the line, preventing oil outflow and avoiding loss of oil and pressure. Environmental protection: no oil spills occur when disconnecting and connecting quick couplings, protecting the environment. Modularization of equipment for easy transport: large equipment or hydraulic tools that need to be portable can be disassembled using quick couplings for transport and reassembled at the destination. Economic value: the above advantages create economic value for customers.
