as stroemungstechnik hose fittings Germany as stroemungstechnik model as stroemungstechnik price

as stroemungstechnik hose fittings connect different hydraulic components (pumps, delivery lines, directional valves, shut-off valves, hydraulic motors, hydraulic cylinders, and some auxiliary components, such as level gauges, thermometers, pressure gauges, etc.) to form a closed-loop hydraulic system. Hydraulic pipe fittings are the connecting accessories in this system. Hydraulic pipe fittings are detachable connectors between oil pipes and oil pipes, or between oil pipes and hydraulic components. They should meet the requirements of easy assembly and disassembly, reliable connection, reliable sealing, small external dimensions, high oil flow capacity, low pressure loss, and good processing technology. Hydraulic pipe fittings are widely used in various aspects of our lives. They are mainly used in hydraulic piping systems in industries such as energy, petrochemicals, electric power, ships, automobiles, rail transit, mining, metallurgy, steel plants, marine engineering, and construction machinery. Construction machinery is where hydraulic pipe fittings are most frequently used.

as stroemungstechnik hose fitting classification

Classification by pipe diameter size: The ends of equal-diameter tees are all the same size; for reducing tees, the main pipe connection size is the same, while the branch pipe connection size is smaller than the main pipe connection size. Classification by process: 1. Hydraulic bulging. Hydraulic bulging of tees is a forming process in which the branch pipe is bulged out through axial compensation of the metal material. The process involves using a special hydraulic press to inject liquid into a pipe blank with a diameter equal to that of the tee. The two horizontal side cylinders of the hydraulic press move synchronously to center and squeeze the pipe blank. After being squeezed, the volume of the pipe blank decreases, and the pressure of the liquid inside the pipe blank increases as the volume decreases. When the pressure required to bulge out the tee branch is reached, the metal material flows along the mold cavity under the dual action of the side cylinders and the liquid pressure inside the pipe blank, thereby bulging out the branch pipe. The hydraulic bulging process for tees can be formed in one step, with high production efficiency; the wall thickness of the main pipe and shoulder of the tee both increase. Because the hydraulic bulging process for seamless tees requires equipment with a large tonnage, it is mainly used in China for the manufacture of standard wall thickness tees smaller than DN400. The applicable forming materials are low-carbon steel, low-alloy steel, and stainless steel with relatively low tendency for work hardening, including some non-ferrous metal materials such as copper, aluminum, and titanium. 2. Hot pressing forming. Hot pressing forming of tees involves flattening a pipe blank larger than the tee diameter to approximately the tee diameter size, opening a hole at the position where the branch pipe will be stretched; the pipe blank is heated, placed into a forming mold, and a punch for stretching the branch pipe is inserted into the pipe blank. Under pressure, the pipe blank is radially compressed. During radial compression, the metal flows toward the branch pipe direction and forms the branch pipe under the stretching of the punch. The entire process is formed through the radial compression of the pipe blank and the stretching of the branch pipe part. Different from hydraulic bulging tees, the metal of the hot-pressed tee branch 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 adaptability to materials, suitable for low-carbon steel, alloy steel, and stainless steel; especially for large-diameter tees with thicker walls, this forming process is usually adopted. Classification by material: carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon chrome asphalt, pvc, etc. Classification by manufacturing method: top-made, pressed, forged, cast, etc.

as stroemungstechnik hose fitting common problems

1. Clear residue. When installing water pipe connectors, completely remove various residues from the pipeline. This can prevent valve core damage, blockages, clogging, and leaks. At the same time, clean the surface to avoid residual building decoration materials. 2. Do not use excessive force when switching. For any household accessory, you do not need to apply excessive force when switching; just shake or rotate it. Even traditional home decorations do not require much effort to tighten them. In particular, do not use the handle as a railing for support. After using for a period of time, disassemble and clean products with outlet filter covers to remove residues. Products with hoses should be kept in a natural stretched state to avoid rupture. 3. Keep household tee joints flexible. The shower metal bellows of household hose fittings should be kept in a naturally stretched state. Do not wrap it around the faucet when not in use. At the same time, whether in use or not, pay attention to avoid blind spots at the connection between the hose and the oil circuit board to prevent hose rupture or damage. 4. Pay attention to regular cleaning. Domestic water pipe connectors that are not used for a long time may also lead to incomplete closure, water leakage, loose handles, loose connectors, and water leakage. Customers can often handle these issues themselves.

as stroemungstechnik hose fitting application

Quick-connect fittings are also commonly known as self-locking fittings or quick-insert sealing fittings. They allow locking of pipes and fittings through simple operation, without the need for nuts or clamps. They can adapt to higher pressures, 70Bar or even higher. Flanged ports or straight round pipes in cooling water channels usually require clamps for ordinary fittings, involving more operational steps and having poor pressure resistance. With technological progress, in addition to self-locking quick-connect fittings, pneumatic quick-connect fittings (automated quick-connect fittings) are better suited for industrial automated production, using air pressure drive. The purpose of using quick-connect fittings is for faster operation. Modern mechanized production emphasizes efficiency and reducing the workload of operators. Their speed is reflected in: convenient handling, fewer operational steps, simple operation, automatic locking, and sealing and disconnecting requiring only one plug and one pull, which is much more convenient compared to ordinary fittings.
