Icotek hose fittings Germany Icotek models Icotek prices

Icotek hose fittings refer to threaded pipe connectors, which are the most common type of pipe fittings in industrial and daily applications. They are mainly used for small-diameter low-pressure pipelines, for locations requiring frequent assembly and disassembly, or as final adjustments for pipelines using threaded fittings. The structural form should preferably adopt a metal-to-metal contact seal. Gasket-sealed structures are typically used in general pipelines transporting water, oil, air, etc., and are manufactured from malleable cast iron. The significance of threaded fittings is that they make pipe connections simpler and disassembly/replacement easier, greatly saving on piping connection costs. They are mainly used for small-diameter low-pressure pipelines, for locations requiring frequent assembly and disassembly, or as final adjustments for pipelines using threaded fittings. Features of threaded fittings: high joint strength and good ductility, allowing full utilization of the strength and ductility of the base material of reinforcing steel. Connection is convenient, fast, and simple to operate. No electricity, gas, or open flame is required during construction connection; there is no oil leakage or pollution. They are corrosion-resistant, leak-proof, anti-detachment, safe, and have a long service life. Application fields: fluid and gas transmission systems in industries related to hydraulics, such as automotive, engineering machinery, lathes, machines, metallurgy, petroleum, mining, construction, chemical industry, shipbuilding, aerospace, military industry, textiles, marine, entertainment, electronics, etc.

Icotek hose fitting classification

The structural forms of fittings are generally divided into three main categories: spiral, flange, and quick-connect. 1. Threaded type: For metal hose fittings with a nominal diameter below 50 mm that withstand higher operating pressures, threaded types are predominantly used. After tightening the threads, the internal and external tapered surfaces on the two fittings mate closely to achieve sealing. The cone angle is generally 60 degrees, though 74 degrees is also used. This structure offers good sealing performance, but concentricity of the two mating parts must be ensured during installation. To address common issues in practical engineering such as repeated assembly/disassembly and difficulty in achieving concentricity, the fitting can also be designed with a tapered surface mating with a spherical head. 2. Flange type: For metal hose fittings with a nominal diameter above 25 mm that withstand general operating pressures, flange types are predominantly used. They seal via a tongue-and-groove mating arrangement. A loose flange, which can rotate radially or slide axially, connects the two bodies under the tensile force of tightening bolts. This structure provides good sealing performance but is difficult to manufacture, and the sealing surfaces are prone to damage. For special occasions requiring quick release, the holes for the tightening bolts can be slotted to create a quick-release flange. 3. Quick-connect type: For various metal hose fittings with a nominal diameter below 100 mm, quick-connect types are generally adopted when rapid assembly and disassembly are required. They commonly use an "O"-shaped sealing ring made of fluoroplastic or special rubber for sealing. When the handle is moved through a certain angle, it is equivalent to locking the jaws of a multi-start thread; the tighter the "O"-shaped sealing ring is compressed, the better the sealing performance. This structure is most suitable for fire scenes, battlefields, and other occasions where rapid installation and removal are essential. A set of fittings can be connected or disconnected within seconds without any special tools.

Icotek hose fitting types

1, Classified by pipe fitting diameter, there are generally equal-diameter tees, reducing tees, etc. 2, Classified by branch direction, there are straight tees and lateral tees. 3, Classified by material, there are carbon steel, alloy steel, stainless steel, copper, pvc tees, etc. 4, Classified by connection method, there are standard tees, threaded tees, compression tees, and socket tees. 5, Tee designation methods are as follows: For an equal-diameter tee, such as "T6" tee, it indicates an equal-diameter tee with an outer diameter of 6 inches. 6, For a reducing tee, for example, "T4×4×3.5" indicates a reducing tee with a same diameter of four inches and a reducing diameter of 3.5 inches. The pressure rating is the same as that of elbows, and the specification range is also the same.

Icotek hose fitting features

Double ferrule fittings feature reliable connection, high pressure resistance, temperature resistance, good sealing and reusability, convenient installation and maintenance, and safe and reliable operation. The working principle of a double ferrule fitting involves inserting the steel tube into the ferrules and tightening the ferrule nut, which presses against the ferrules, causing them to cut into the tube to form a seal. No welding is required when connecting to steel tubes, which aids in fire prevention, explosion protection, and high-altitude work, while eliminating drawbacks caused by improper welding. Therefore, it is a relatively advanced connector used in piping systems for automatic control devices in oil refining, chemical, petroleum, natural gas, food, pharmaceutical, and instrumentation systems. It is suitable for connecting pipelines carrying oil, gas, water, and other media. A compression tube 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 tube and inserted into the fitting body, tightening the nut causes the nut to move forward, pushing the rear ferrule forward. Simultaneously, the rear ferrule 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 mate with the tapered surface of the fitting body, while the inner edge uniformly bites into the seamless steel tube, forming an effective seal.
