Eisele Pneumatic hose fittings Germany Eisele Pneumatic models Eisele Pneumatic prices

Eisele Pneumatic hose fittings connect different hydraulic components to form a closed-loop hydraulic system, serving as a connecting accessory. They connect different 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.

Eisele Pneumatic hose fitting manufacturing process

Tee joint forming involves flattening a pipe blank with a diameter larger than the tee to approximately the tee diameter, and opening a hole at the branch location for stretching. The pipe blank is heated, placed into a forming die, and a punch for stretching the branch is inserted into the blank. Under pressure, the pipe blank is radially compressed; during this radial compression, metal flows toward the branch direction and forms the branch under the stretching action of the punch. The entire process forms the shape through radial compression of the pipe blank and stretching of the branch section. Unlike hydraulic bulging tees, the metal in the branch of the tee joint is compensated by the radial movement of the pipe blank, so it is also called the radial compensation process. Since the tee is pressed after heating, the equipment tonnage required for material forming is reduced. Hot-pressed tees have wide material adaptability, suitable for low-carbon steel, alloy steel, and stainless steel materials; especially for large-diameter tees with thicker walls, this forming process is commonly used.

Eisele Pneumatic hose fitting production key points

Stainless steel elbows, 1. When using welding rods, keep them dry. Titanium-calcium type rods should be dried at 150℃ for 1 hour, and low-hydrogen type rods should be dried at 200-250℃ for 1 hours (do not repeat drying multiple times, otherwise the coating may crack and peel). Prevent the welding rod 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 using similar types of welding rods, preheating above 300℃ and post-weld slow cooling around 700℃ are required. If post-weld heat treatment is not possible for the weldment, chromium-nickel stainless steel welding rods 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 welding rods, preheating above 200℃ and post-weld tempering around 800℃ are required. If the weldment cannot undergo heat treatment, chromium-nickel stainless steel welding rods should be selected.

Eisele Pneumatic hose fitting classification

Air type: Mainly used for quick installation of air lines and accessories for pneumatic tool connections. Corresponding to their applications, there is a rich variety of body materials, sizes, and installation shapes. Precautions: Do not use for purposes other than fluids. Do not use with fluids other than the applicable fluid. Do not exceed the maximum operating pressure during use. Do not use outside the operating temperature range to prevent deformation of sealing materials, which can easily lead to leaks. Do not manually strike, bend, or stretch to prevent damage. Do not use in environments contaminated with metal powder or sand/dust; quick connectors designed for such harsh conditions ensure long service life. Accumulation of debris can cause malfunction or leakage. Do not disassemble quick connectors. 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: 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 operating temperature range to prevent wear or leakage of sealing materials. Do not manually strike, bend, or stretch to prevent damage. Do not use in environments contaminated with metal powder or sand/dust to prevent malfunction or leakage. Accumulation of debris can cause malfunction or leakage. Do not use in areas where gas accumulates. Do not perform loading/unloading operations when open flames are nearby. In case of flashback, replace with new products. When installing hoses, ensure they are 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 base of the connector 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 leakage is detected, stop use immediately and replace with a new product. Confirm that the gas welding torch valve is closed before connecting. For welding applications, note that after a period of use, safety checks on connectors and pipelines should be conducted to check for gas leaks.
