Transition concentric seamless welded (water, steam, nonaggressive liquids).
- Diameter is 325 * 108 mm
- Material: steel
The specifications and technical documentation is defined by GOST 17378 - 2001 on concentric transitions
Types of transitions:
• Eccentric transition
• Concentric transition
Transition steel concentric - the pipeline design detail intended for connection of pipes on sites of change of diameter of the pipeline. With the help perekhodovkonets of a pipe of bigger diameter it is possible to connect to the end of a pipe of smaller diameter and vice versa, as a result increase or reduction of the movement of a stream of substance. Transitions concentric in different areas are applied: oil and gas industry, chemical and power industry, and also municipal sphere, etc. Concentric transition is made the next ways: stamping, rolling from sheet and pipe preparations with the subsequent welding and assembly, stamping of conic forgings with the subsequent fur. completion. In production of this production apply: carbonaceous brands became (in small and sredneagressivny environments), namely: 10; 20; st3, alloyed and high - alloyed became (high - hostile environment), namely: 09G2S, 15HM, 15H5M, 12H18N10T.
Loading of metal is carried out by the crane only in the opened car.
