GOST 13965-74 Reducing tees for connecting pipelines along the outer cone
Tees in accordance with GOST 13965-74 – The design feature is that the working flow can only be withdrawn at an angle of 90 0 with respect to the main pipeline and the tees have different diameters of the through holes in the branches and allow connecting pipe sections with different diameters.  ;
Description of product design features
Reducing tees should be made in five versions:
- performance 1 – hell. 1
- performance 2 – hell. 2
- performance 3 – hell. 3
- performance 4 – hell. 4
- performance 5 – hell. 5
Production material: from steel grades 45, 12X18H9T, 13X11H2V2MF, aluminum alloy and bronze.
Coating of reducing tees with zinc, cadmium, anodizing, passivation, chemical anodizing is carried out in our own galvanizing shop.
