Sveflow AB hose fittings Germany Sveflow AB model Sveflow AB price

Sveflow AB hose fittings are components in hydraulic systems used to connect pipelines or attach pipelines to hydraulic components. This is a general term for connectors that can be installed and removed in fluid passages. Main types include: welded, bite-type, crimped, and flared.

Sveflow AB hose fitting function

The role of a rotary joint is to serve as a sealing device for connection, inputting liquid from one side of the pipeline into rotating or reciprocating equipment and discharging it from there. For bent pipes, especially metal hoses, a considerable total length is required for the stroke due to the large bending radius. By installing a rotary joint at the base, the task can be completed with the shortest hose length. This not only saves space but can also be used to absorb hose twisting depending on the method of use. Rotary joints can be used in sets for hydraulic and water piping to accommodate complex movements. They can be used with confidence in locations where hose installation is difficult or where significant leakage is a concern, as well as under harsh environmental conditions such as high temperature and high pressure. For example, when a boiler burner is ignited, rotary joints used for inserting oil and steam piping can operate without problems even under harsh conditions of high temperature, high pressure, and complex motion. In summary, rotary joints can be equipped on cylindrical, drum-shaped, frustum-shaped, and spherical rotating equipment, as well as equipment that reciprocates or oscillates at any angle, using gases and liquids such as steam, water, oil, gas, air, brine, and ammonia for heating, drying, and cooling. They are also suitable for pneumatic and hydraulic clamping, braking, and gripping equipment.

Sveflow AB hose fitting classification

Air type: Mainly used for quick installation of air pipelines and accessories for pneumatic tool connectors. 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 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 subject to artificial impact, bending, or stretching to prevent damage. Do not use in places contaminated with metal powder or sand/dust; however, quick connectors designed for such environments can ensure long service life under harsh conditions. 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 pipe 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 subject to artificial impact, bending, or stretching to prevent damage. Do not use in places 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. If flashback occurs, replace with a new product. When installing hoses, ensure they are free of oil to prevent spontaneous combustion. When reinstalling hoses, cut the end of the hose from more than 3 centimeters. Do not use for purposes other than quick fluid connectors. Insert the hose firmly into the base of the interface and secure it with a hose band 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 exists, 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.

Sveflow AB hose fitting forming method

The hot push elbow forming process uses a special elbow pushing machine, core mold, and heating device. The blank placed on the mold is pushed forward by the pushing machine, undergoing heating, diameter expansion, and bending during movement. The deformation characteristic of hot push elbows is based on the principle that the volume of metal material remains unchanged before and after plastic deformation. The pipe blank diameter is determined accordingly; the adopted pipe blank diameter is smaller than the elbow diameter. The deformation process of the blank is controlled by the core mold, causing the compressed metal at the inner arc to flow and compensate for other parts thinned by diameter expansion, thereby achieving an elbow with uniform wall thickness. The hot push elbow forming process features an attractive appearance, uniform wall thickness, and continuous operation, making it suitable for mass production. Therefore, it has become the main forming method for carbon steel and alloy steel elbows, and is also applied in the forming of stainless steel elbows of certain specifications. Heating methods during the forming process include medium-frequency or high-frequency induction heating (heating coils can be multi-turn or single-turn), flame heating, and reflection furnace heating. The choice of heating method depends on the requirements of the formed product and energy availability.
