Transitions fine-molded for parawires

Transition steel concentric welded.

Transition concentric steel - the pipeline element connecting pipes of diameter, different in size (big and small), the having appearance of the truncated cone. Concentric transition allows either to increase, or to narrow a stream of the Wednesday transported on the pipeline. This transition is applied, as a rule, to pipes on suspended support.
Most often, as material for transition of concentric steel the alloyed steel acts. Thanks to its excellent welded properties, it is widely applied to production of welded designs. Such transition can be used with success for transportation on it liquid, gaseous, loose substances.

In production transition concentric is made of steel of various brands. Steel transitions are widely applied in pipelines chemical, oil and gas, power, municipal and many other spheres of the industry. For each separate task facing transition concentric steel it is necessary to choose truly brand of steel of which it has to be made. It has to be calculated on certain service conditions - pressure, temperature, climate, properties of the moved environment. In the course of a pipeline construction often there is a requirement of connection of two pipes of different diameter. Reliable connection of pipe pieces on a site of change of diameter of the pipeline is provided by connecting elements - transitions.

Transition is concentric: types

On manufacturing techniques and on use steel transitions are divided into two types: seamless stamped concentric and welded sheet. Sometimes on sale dot and cast steel transitions, however meet as a type of steel transition they were not widely adopted.
Depending on qualitative characteristics of a working environment, steel perekhodyizgotavlivat from different brands of steel. Transition steel in small and sredneagressivny environments (gas, oil, oil products, etc.) is made for operation from brands of carbonaceous steel 10, 20, STZ. Transition steel with working high-hostile environment is made for pipelines from the alloyed and high-alloyed steel of brands 5XM, 15X5M, 12X18H10T. Increased requirements to oxidation of hostile environment assume use of transitions corrosion-proof. Transitions corrosion-proof find application in food, chemical, power and other spheres of the industry. Temperature range of operation of transitions makes from-70 to +450 °C with a pressure up to 16 MPas.
