KNORR hose fittings, Germany KNORR models, KNORR prices

KNORR hose fittings are connectors that allow pipeline connection or disconnection without tools. 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 oil cylinders in die-casting machines. Test function: testing for vacuum, pressure resistance, leakage, operation, etc. Conveying function: conveying and handling of solids such as bolts and nuts, as well as electrical conductivity. Filling function: inert gases, nitrogen, PG, carbonic acid. Time and labor saving: when disconnecting and connecting oil lines via quick couplings, the operation is simple, saving time and manpower. Oil saving: when the oil line is disconnected, the check valve on the quick coupling can close the oil line, preventing oil from flowing out and avoiding loss of oil and oil pressure. Environmental protection: when the quick coupling is disconnected and connected, oil does not spill, protecting the environment. Equipment modularization for convenient transport: large equipment or hydraulic tools that need to be portable can be disassembled using quick couplings for transport, and then assembled for use at the destination.

KNORR hose fitting distinctions

The difference between internal threads and external threads is: internal threads are female threads, with the thread located inside a hole; external threads are male threads, with the thread located on the outer surface of a cylinder. Internal and external threads are industry terms referring to the thread mating process used in screw and nut connections. Screw and nut mating allows for easy disassembly and convenient installation, and is one of the commonly used connection and fixation processes in mechanical equipment, pipelines, and metal structure engineering installation. For different names of the same type of pipe fitting, remember this simply: an internal connector has external threads; an external connector has internal threads. Threaded fittings are generally used for pipelines to provide connection. External thread: refers to the threaded port on the outside of pipelines, etc., which can generally be touched directly. Internal thread: refers to the threaded port inside pipelines, etc., which generally requires reaching inside to touch. In industry, you may also encounter right-hand threads and left-hand threads. Right-hand thread: threads that tighten by turning clockwise (righty-tighty), which are very common in daily life, with screws being the most typical example. Left-hand thread: threads that must be turned in the reverse direction to tighten, which are not very common in daily life but are seen more often in specialized fields, such as ventilation.

KNORR hose fitting crimping

How to crimp high-pressure pipe fittings: first, the international metric internal thread flat-face fitting; second, the international metric bite-type fitting; third, the international metric internal thread 74 degree internal cone face fitting; fourth, the international metric internal thread spherical face fitting; fifth, the mining hydraulic support fitting. There are some points to note when using high-pressure hydraulic hose fittings: 1. When handling high-pressure hydraulic hoses, care must be taken to avoid friction on the outer surface to prevent damage. Although the hose is meant for use, we must not allow leaks to appear on the outer surface of the high-pressure hose. 2. Do not bend the high-pressure hydraulic hose, as this will cause internal damage, adding unnecessary trouble for future use. 3. Do not put the high-pressure hydraulic hose into immediate use; it is recommended to flush it first with water or similar fluid. Some high-pressure hoses are acid and alkali resistant, so we cannot use fluids that conflict with the current medium for testing. 4. When installing high-pressure hydraulic hose fittings, they must be tightened securely to prevent fluid leaks.

KNORR hose fitting classification

Welded pipe fittings can also be called 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 pipeline closure, with functions similar to plugs. Caps include convex caps, reducing sections, conical shells, flat covers, and caps with narrowed openings. Among them, 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, but from the perspective of manufacturing difficulty, the variety of quick coupling types shows an upward trend. We should select suitable welded quick couplings, welded pipe fitting caps, etc., according to our own needs. Welded quick couplings can also be abbreviated as quick couplings; they are a type of welded pipe fitting. Pipe fitting caps are also required during the connection of pipe fittings, and there are many types of pipe fitting caps. So 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 welded pipe fitting caps, fusion caps, adhesive caps, bite-type caps, standard caps, rubber ring connection caps, socket caps, etc.
