Working pressure of rotary joint:
The normal working pressure range for rotary joints is 10 to 315 bar
Conditions for use of rotary joints:
The DNF type rotary joint we provide can be widely used in various occasions, suitable for various media such as water, sewage, hydraulic oil, other oils, chemical crystals, coal gas, dust, mud, etc.
By joining the rotary joint with bent pipes or corner components, flexible pipelines of different structural styles can be formed.
We provide this set of assembled flexible pipelines, which can be sealed with different materials according to the needs and temperature of the application site.

Main structure and working principle
Structural composition: usually composed of an elbow shell, a rotating outer tube (connecting moving parts), a sealing friction pair (such as graphite ring/spherical seal), an elastic compensation mechanism (spring), and supporting bearings; Some models include siphon tubes (for steam condensate discharge).
Sealing principle: relying on the pre tightening force of the spring and the pressure of the medium to push the sealing surface (such as the spherical or end surface) tightly together. When the sealing surface wears out, the spring automatically compensates for axial displacement to maintain the sealing performance; Bearing support ensures smooth rotation.
Movement mode: divided into continuous 360 ° full rotation transformation (such as universal joint) and reciprocating swing type (angle limited, such as ± 45 ° or ± 90 °), the latter is commonly used for guiding switches between rigid pipelines. ‌‌
We can use inner and outer double-layer seals in the rotary joint according to customer requirements to ensure “no leakage of water”.
The DNF rotary joint can be combined with various threaded or flange joints. We suggest ordering the necessary connectors at the same time as ordering the adapter.
It is a company that integrates scientific research, development, and manufacturing. Since its establishment, the company has made significant improvements in product quality and exterior design to meet market demands and better serve new and old customers. Particularly, there have been significant improvements in mechanical seals, resulting in a more rational internal structure, more stable seals, and extended service life. The product has the advantages of stable quality, excellent performance, and easy installation, which not only solves the problems of “running, emitting, dripping, and leaking” for users, saves energy, but also reduces the frequency of maintenance and the losses caused by frequent start-up and shutdown, and is highly praised by new and old users.
The company’s main products include rotary joints, metal hoses, high-pressure rubber hoses, corrugated expansion joints, quick couplings, sealing rings, siphons, flow sensors, drain valves and other products and fittings. The product is widely used in industries such as steel, papermaking, packaging, plastics, printing and dyeing, rubber, chemical fibers, printing, cigarettes, mining, electricity, petroleum, chemical, pharmaceutical, food, and construction.
