SR Systems hose connectors, German SR Systems models, SR Systems prices

SR Systems hose connectors are end-type straight fittings used to connect metal hoses to enclosures; they are detachable connection points between components and pipelines. They play an indispensable role in pipe fittings and are one of the two main components of hydraulic piping. Hose connectors are high-quality flexible pipes in modern industrial piping systems. They mainly consist of bellows, a wire braid, and connectors. The inner tube is a thin-walled stainless steel bellows with a spiral or annular shape, and the outer braid of the bellows is woven from stainless steel wire or steel strip according to specific parameters. The connectors or flanges at both ends of the hose match the connectors or flanges of the customer's pipeline. The bellows of the hose are formed by high-precision plastic working of extremely thin-walled seamless or welded stainless steel pipes. Due to the elastic characteristics of the bellows profile, the hose has good flexibility and fatigue resistance, making it easy to absorb cyclic loads from various motion deformations, especially the ability to compensate for large displacements in piping systems.

SR Systems hose connector features

Double ferrule fittings feature reliable connections, high pressure resistance, temperature resistance, good sealing and repeatability, convenient installation and maintenance, and safe and reliable operation. The working principle of double ferrule fittings involves inserting the steel pipe into the ferrule and tightening the ferrule nut, which presses against the ferrule, causing it to cut into the pipe to create a seal. No welding is required when connecting to steel pipes, which is beneficial for fire prevention, explosion protection, and high-altitude work, and eliminates the drawbacks of improper welding. Therefore, it is a relatively advanced connector in the piping of automatic control devices in oil refining, chemical, petroleum, natural gas, food, pharmaceutical, and instrumentation systems. It is suitable for connecting oil, gas, water, and other pipelines. The ferrule-type pipe fitting consists of four parts: the fitting body, front ferrule, rear ferrule, and nut. When the front and rear ferrules and the nut are placed on the steel pipe and inserted into the fitting body, tightening the nut moves the nut forward, pushing the rear ferrule forward, which in turn pushes the front ferrule forward. The tip of the fitting body squeezes the front ferrule inward, causing the outer side of the front end of the ferrule to fit tightly against the conical surface of the fitting body, while the inner edge evenly bites into the seamless steel pipe, forming an effective seal.

SR Systems hose connector working principle

1, the basic structure of this type of connector is relatively simple, consisting of only three basic parts: the fitting body, the ferrule, and the nut. The main component is the ferrule, which is a metal ring with a cutting edge at the front. The international standard GB3764-83 recommends a unified I type shape for the cutting edge. 2, the ferrule, which plays the main sealing role in this connector, moves axially along the inner conical hole of the fitting body under the axial force of the tightening nut R. At the same time, the cutting edge end undergoes radial contraction under the radial reaction force R', eliminating the gap between the ferrule and the pipe, causing the cutting edge to contact the pipe surface. At this point, the pipe no longer rotates; continuing to rotate the nut causes the ferrule cutting edge to firmly bite into the pipe to ensure sealing. Another sealing stage is where the 13° chamfer at the end point of the ferrule cutting edge and the intersection line (edge) with the outer circle come into tight contact with the annular conical surface of the fitting body to form a sealing band, which is the main part of the ferrule-type seal. The 86° conical surface at the tail of the ferrule undergoes radial contraction under the force of F, tightly gripping the connected pipe, while the middle part bulges slightly. Thus, the ferrule has axial elastic deformation, which plays a favorable role in ferrule sealing and preventing the tightening nut from loosening.

SR Systems hose connector functions

Exchange function: Accessories for pneumatic and hydraulic tools, cylinders, hydraulic cylinders, and machinery related to metal molds. Maintenance function: Cooling devices for computers, maintenance of die-casting machine cylinders. Testing function: Testing for vacuum, pressure resistance, leakage, operation, etc. Transport function: Transport and handling of solids such as bolts and nuts, as well as conductive functions. Filling function: Inert gases, nitrogen, PG, carbonic acid. Connection function: Fixtures for fishing rods and pocket laser discs, connections for mobile operations, and uses other than fluid transport. Time and labor saving: Disconnecting and connecting oil lines via quick connectors is simple, saving time and manpower. Oil saving: When the oil line is disconnected, the check valve on the quick connector can close the oil line, preventing oil from flowing out and avoiding loss of oil and oil pressure. Environmental protection: When quick connectors are disconnected and connected, oil does not spill, protecting the environment. Equipment disassembly for easier transport: Large equipment or hydraulic tools that need to be portable can be disassembled using quick connectors for transport and reassembled at the destination. Economic: All the above advantages create economic value for customers.
