Valves

In the article "Overview of patents on new designs of ball valves or create a new crane" were considered such as ball valves, Orbit Valve Company Cameron and identified the main drawback of such a design – the need to press the stopper seat, which then loaded the whole area of the cross-section of the working pressure sredy.Izvlekaya the best of what is inherent in the considered crane conclusions were drawn: – to reduce the price of a new construction crane should have not treated the cork, and sealing belts only processed – for ease of operation and extend the life of a new construction crane should be able to wear compression adjustments during the operation, without removing the valve from the pipeline – in order to reduce prices and ease of maintenance control valve should be the usual quarter-negotiable drive – to reduce the size instead of moving traffic jams, must be disposed of unloaded from the pressure of the saddle, which will use less power and drive value. The idea to unload the pressure locking body has long been known and used in many constructions of valves. A related site: real-estate developer mentions similar findings. An example is the well-known cellular valves that are used in cases where the pressure drop across the valve does not allow the use of unbalanced butterfly knots. Cell (or kletkovy) throttle node, gets its name from the perforated sleeve within which the plunger moves (which originally was called a cell). The location and area of perforation sleeve shall determine the capacity of valve. .

The Advantage Of Cast Flanges

In the market of components to lines of recent times do not cease the debate which is better and cheaper than casting or forging billets. Wants to share specific views on this result. NGOs Engineering Tehnolgii prepared for use in pipeline transportation systems, chemical, oil, gas pipelines, as well as for setting up, restoration of objects to petrochemical plants. An impressive field of application flanges, fasteners, hits the concentric and the rest of our products is predetermined by the different types of steels used for creating parts: 09G2S, 40X, 35, 15H5M, 14H17N2, 20HN3A, 25H2M1F, 12X18H10T, 06HN28MDT, 10H17N13M2T. Land use data types steel is in an infinite range: operating areas – from water to areas of highest aggressiveness. operating temperatures from -150 to 1000 Co instructions centrifugal electroslag casting provide first-class quality of cast steel by refining it in the electroslag melting process, the application of additional technological means to extract the directional solidification of casting. all the features of these matters, while not inferior to forged, but surpass them by the properties of ductility, toughness with a similar figure of merit.

Our production is based on ispolzovaniiii electroslag methods developed in the Institute of Electric. Paton. Omsk master added to and changed partially in-service units are created in the 70 years preceding century. The result is a modern, productive installation of electronic subsystem regulirovaniyaiya.produktsiya company
