| Coloumn bindings | ||||||
| The coloumn bindings OKK are intended for binding of 2 or more coloumns and check of pressure in inter coloumn space. Coloumn bindings are produced at operating pressure of 21 and 35 Mpa. Depending on the structure of downhole environment, bindings are produced as the following: Usual - for media containing petroleum,gas,gas condensate,flash fund,cement starry,particles of bored soil,water and their mixtures. Corrosion resistant (K2 and K2I): for media containing oil,gas,gas condensate,flush fluid,cement starry,particles of bored soil,water and their mixtures containing H2S and CO2 up to 6% in volume. |
