factories representing the chemical industry, the application of a huge number of special techniques and equipment. Among the variety of these devices deserve special attention, quick couplings, the couplings, as well as composite and rubber hoses.
Quick coupling
This category of equipment is represented by a coupling with an internal cylindrical thread or adapter for the hose. In the first case uses an internal spring-loaded locking pin, the end of which there is a special snap ring. It provides the fixation of the post in a perpendicular position relative to the hose. This ensures facilitating the manipulation of the levers when removing. Moreover, this design feature helps to avoid inadvertent disconnection. The coupling with the internal adapter on the hose operate in a similar way.
the couplings
This is an equipment for chemical industry designed to prevent spill of transported oil products as a result of involuntary departure of vessels from the pier. The same emergency situation may occur caused by delayed pick-up rail or tank trucks. Thus, the use of the breaking of the coupling can completely eliminate the dependence on the human factor.
the advantages of clutches with cone valves note:
- minimum differential pressure;
- high throughput level;
- resistance to lateral forces.
Hoses
In the chemical industry can not do without hoses. They can be rubber or composite. The first option is used for loading or unloading extremely aggressive chemicals from rail and road tankers. In this case, use either pressure, or pressure-suction hose with a diameter of 8 inches.
But far more common are composite hose designed for chemical products that come into contact with the external environment. Such products are usually referred phosphoric acid and phenol. Composite hoses are also relevant for application in marine environments. In these conditions, can be used additionally and equipment for bunkering.
In conclusion, I should add that when selecting a hose it is necessary to pay attention to the 4 main technical parameter: inner diameter, bending radius, weight and working pressure.
