Zookdisk hose fittings, Germany Zookdisk models, Zookdisk prices

Zookdisk hose fittings are connection tools between pipes and serve as detachable connection points between components and pipes. Main pipe fittings come in a wide variety; commonly used pipe fittings are generally classified into hard pipe fittings and hose fittings. Hard pipe fittings include flared, compression, and welded types, while hose fittings are primarily crimped rubber hose fittings. A compression pipe fitting consists of three parts: the fitting body, the ferrule, and the nut. When the ferrule and nut are placed on the steel pipe and inserted into the fitting body, tightening the nut causes the outer side of the ferrule's front end to seat against the conical surface of the fitting body, and the inner cutting edge bites uniformly into the seamless steel pipe, forming an effective seal. These are sealed pipe fittings suitable for non-corrosive or corrosive media such as oil, water, and gas. The specifications for use with aluminum-plastic pipes are relatively flexible. After connection to the pipeline, they feature reliable connections and good sealing performance.

Zookdisk hose fitting classification

Welded pipe fittings are also known as quick couplings, welded quick couplings, or welded-type quick couplings. The caps for welded pipe fittings are similar to plugs or end caps. They are mainly used for closing pipelines, functioning similarly to plugs. Caps include convex caps, reducing sections, conical shells, flat covers, and caps with contracted openings. Convex caps also include elliptical caps, dished caps, hemispherical caps, and spherical crown caps. From a stress perspective, among convex caps, the performance of hemispherical caps shows a downward trend; however, in terms of manufacturing difficulty for fittings, the variety of quick couplings shows an upward trend. We should select suitable welded quick couplings and welded pipe fitting caps according to our needs. Welded quick couplings can be abbreviated as quick couplings and are a type of welded pipe fitting. The caps for welded pipe fittings are also required during the connection of pipe fittings, and there are many types of pipe fitting caps. How are welded pipe fitting caps classified? If classified by material, they can be divided into plastic caps, forged steel caps, PPR caps, graphite caps, alloy caps, pvc caps, ABS caps, cast steel caps, cast iron caps, stainless steel caps, rubber caps, and pe caps. If classified by connection method, they can be divided into threaded caps, clamp caps, quick caps for welded pipe fittings, fusion caps, adhesive caps, compression caps, standard caps, rubber ring connection caps, socket caps, etc.

Zookdisk hose fitting functions

Insert the steel pipe into the ferrule and tighten it using the ferrule nut to press against the ferrule, cutting 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 operations, and eliminates the drawbacks of improper welding. The mechanical advantages and geometry of the fitting make this mechanical device a sealing component capable of preventing leaks. The mechanical thrust pushes the rear ferrule against the conical back of the front ferrule, while simultaneously pushing the front ferrule into the tapered contraction mouth of the fitting body. The ferrule is squeezed onto the conduit by an inward radial force. At this point, withdrawing the front ferrule forms a full-face seal on the tapered contraction surface of the fitting body. When hand-tightening feels secure, rotate the ferrule nut further from this manually tightened position to ensure uniform thrust on the seal. This ensures effective sealing even in high-pressure and ultra-high vacuum environments. Therefore, it is a relatively advanced connector for piping in automatic control systems in oil refining, chemical, petroleum, natural gas, food, pharmaceutical, and instrumentation sectors.

Zookdisk hose fitting selection criteria

1, fluid type, and temperature (please select quick couplings with body and sealing materials suitable for the fluid type and temperature). Depending on the fluid, the suitable body and sealing materials differ. For example, for air, steel quick couplings are recommended; for water, choose brass or stainless steel. 2, liquid pressure (please select quick couplings with pressure resistance suitable for the fluid pressure). Fluid pressure is also key to selecting quick couplings. Hydraulic quick couplings are serialized between 5.0Mpa (51kgf/cm&²) and 68.6Mpa (700kgf/cm&²). Corresponding to pressure resistance characteristics, the structure of quick couplings also differs. 3, automatic shut-off valve structure (please select quick couplings with valve structures suitable for piping applications). Valve structures include two-way shut-off, one-way shut-off, and two-way open types. Note that except for the two-way shut-off type, fluid will flow out from the piping upon disconnection. 4, operating environment of the quick coupling (please select quick couplings with structures and materials suitable for the operating environment). Consider the humidity, dust conditions, and corrosiveness of the operating environment when selecting the type, body material, and sealing material of the quick coupling. 5, ensure that the connection threads of the selected quick coupling are consistent. When using products from different brands, it is best to use male and female connectors from the same brand. If cross-brand usage is necessary, consult the supplier's technical staff before use to confirm compatibility. 6, installation shape and dimensions. Determine the model and material of the quick coupling, and specify the assembly shape and dimensions corresponding to the piping characteristics. Note that dimensions are related to fluid flow rate.
