D+P hose connector Germany D+P model D+P price

D+P hose connectors are accessories that connect different hydraulic components to form a closed-loop hydraulic system, serving a connecting function. They connect various hydraulic components (pumps, delivery lines, directional valves, shut-off valves, hydraulic motors, hydraulic cylinders, and auxiliary components such as level gauges, thermometers, and pressure gauges) to form a closed-loop hydraulic system.

D+P hose connector manufacturing process

Includes a sealing ring, a connection part, and a union nut for connecting the pipe; therefore, the sealing ring is designed as a ring cutter with one or more cutting edges. By screwing the union nut onto the connection part, the ring cutter can be inserted into the bore of the connection part, which has a tapered surface. The outside of the sealing ring has an annular reinforcement on the nut side. This annular reinforcement forms an annular surface at its transition zone towards the narrow ring section. The inclination of this annular surface, formed by the reinforced part of the ring cutter, relative to the pipe axis is 45°-90°. When fully assembled, the axial length of the annular reinforcement allows the transfer element located on the annular surface to imprint its own negative image structure onto the end face of the connection part. The transfer element has a three-dimensional profile, the negative image of which can be transferred to the surface of the connection part. Similar to die stamping, the assembler applies pressure to imprint the negative image onto the surface of the connection part.

D+P hose connector classification

Welded pipe fittings are also known as quick connectors, welded quick connectors, or welded-type quick connectors. 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 narrowed openings. Convex caps include elliptical caps, dished caps, hemispherical caps, and spherical crown caps. From a stress perspective, the performance of hemispherical caps among convex caps shows a downward trend, but from a manufacturing difficulty perspective, the variety of quick connector types shows an upward trend. We should select suitable welded quick connectors and welded pipe fitting caps according to our needs. Welded quick connectors can be abbreviated as quick connectors and are a type of welded pipe fitting. Pipe fitting caps are also required during connection, and there are many types of caps. How are welded pipe fitting caps 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. By connection method, they can be divided into threaded caps, clamp caps, quick caps, hot-melt caps, adhesive caps, ferrule caps, standard caps, O-ring connection caps, and socket caps.
