Have you heard of metal hose, I believe that many friends do not know what metal hose, so here we will give you an introduction to what is metal hose, metal hose has what uses and metal hose connection is how it, together with a look at it.
What is a metal hose
Metal hose is an important connecting component in engineering technology, by the combination of corrugated flexible pipe, mesh sleeve and joints. In a variety of gas, liquid pipeline system and length, temperature, position and angle compensation system as a compensation element, sealing element, connecting element and vibration damping element, used in aviation and aerospace, petrochemical industry, mining and electronics, machinery shipbuilding, medical and health care, textile and electronics, energy and construction and other fields.
The metal hose is made of austenitic stainless steel or materials required by the user, with excellent flexibility, corrosion resistance, high temperature resistance (-235 ℃ ~ +450 ℃), high-pressure resistance (up to 32MPa), in the pipeline can be connected in any direction for temperature compensation and absorption of vibration, to reduce the noise, to change the direction of the medium transport to eliminate the vibration between the pipeline or between the pipeline and the equipment. Piping or piping and equipment between the mechanical displacement, etc.,
double-flange corrugated metal hose on the displacement, vibration of a variety of pumps, valves and other flexible joints are particularly suitable.Metal hose use
Metal hose has many types, mainly various specifications of small caliber instrumentation with threading hose, stainless steel shaped tube, shower hose, UL hose, single and double-button stainless steel hose, galvanized hose, plastic-coated hose,
explosion-proof hose, classification societies special hose, fiber-optic cable protection tube.1, armored fiber optic cable, precision optical ruler, optical measuring instruments, medical instruments, machinery and equipment with wire protection tube;
2, applicable to public telephones, remote water meters, door magnetic alarms, and other need for wire safety protection equipment;
3, a variety of small wires of the protection of the tube;
4, all kinds of computers, robots and so on, the network line protection tube. Tubes for protection of computers, robots and so on.
Metal hose connection
1, flange connection, due to different working conditions, both ends are fixed flange connection, generally used for short length occasions. If one end for the fixed flange, one end for the live flange, this structure is easy to connect, the bolt is easy to center, can effectively prevent the metal soft connection to torsion. Mainly used in petrochemical, electric power, metallurgy and other industries.
2, welding connection, due to the use of receiver butt welding connection, no leakage problems, with high strength, long service life and other characteristics, especially for high-pressure occasions, widely used in petrochemical, pharmaceutical and other industries.
In summary, we understand the characteristics of the two types of metal hose connection, to facilitate our future in the installation and selection of metal hose. Because there are many kinds of metal hose connection, the most common is the above two.
