ASAHI hose fittings Germany ASAHI model ASAHI price

ASAHI 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.

ASAHI hose fitting installation

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

ASAHI hose fitting material classification

1. Austenitic stainless steel: The matrix is primarily composed of austenite structure (γ phase) with a face-centered cubic lattice. It is non-magnetic and is mainly strengthened by cold working (which may induce some magnetism). 2. Austenitic-ferritic (duplex) stainless steel: The matrix contains both austenitic and ferritic phases (the content of the minor phase is generally greater than 15%). It is magnetic and can be strengthened by cold working. 3. Ferritic stainless steel: The matrix is primarily composed of ferrite structure (α phase) with a body-centered cubic crystal lattice. It 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 structure. It is magnetic, and its mechanical properties can be adjusted by heat treatment. 5. Precipitation-hardening stainless steel: The matrix is austenitic or martensitic structure, and it can be hardened (strengthened) by 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 as equipment materials in power stations, chemical industries, and petroleum industries. Stainless steel elbows have poor weldability; attention should be paid to welding processes, heat treatment conditions, and the selection of suitable welding electrodes.

ASAHI hose fitting classification

Air type: Mainly used for quick installation of air lines and as connector accessories for pneumatic tools. Corresponding to their applications, there is a rich variety of body materials, sizes, and installation shapes. Precautions for use: Do not use for purposes other than fluid handling. Do not use with fluids other than the applicable fluid. Do not exceed the maximum operating pressure during use. Do not use outside the specified temperature range to prevent deformation of sealing materials, which can easily lead to leaks. Do not subject to artificial impact, bending, or stretching to prevent damage. Do not use in environments contaminated with metal powder or sand/dust. Quick connectors can be used in harsh working conditions and ensure long service life. Attachment of debris can cause malfunction or leakage. Do not disassemble the quick connector. Gas type: Mainly used for general fuse piping, featuring high flow rate, durability, and corrosion resistance. Body materials, sizes, and installation shapes are diverse. Precautions for use: Fluid must flow from the sleeve side to the plug side. Use sealing material for external threads of controlled threads. When installing threads, do not exceed the maximum tightening torque to prevent damage. Do not use for purposes other than quick fluid connectors. Do not use with fluids other than the applicable fluid. Do not connect with quick fluid connectors from other manufacturers. 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 or sand/dust to prevent malfunction or leakage. Attachment of debris can cause malfunction or leakage. Do not use in places where gas accumulates. Do not perform loading/unloading operations when there is an open flame nearby. In case of flashback, replace with a new product. When installing hoses, ensure they are absolutely free of oil to prevent spontaneous combustion. When reinstalling hoses, cut the hose end from a point greater than 3 centimeters. Do not use for purposes other than quick fluid connectors. Insert the hose firmly into the root of the interface and secure it with a hose clamp or nut. To prevent moisture absorption, store indoors. Do not use cracked hoses to prevent leakage and detachment. Perform a leak check before use. If a leak is detected, stop use immediately and replace with a new product. Confirm that the gas welding gun valve is closed before connecting. For welding applications, note that after a period of use, safety checks on joints and pipelines should be conducted to check for gas leaks.
