OST 1 13838-81 Straight adapters with compression nuts
Adapters according to OST 1 13838-81 – the design feature lies in the crimp nut (made of steel 13Kh11N2V2MF-Sh) and the manufacture of titanium alloy VT3-1.
Description of product design features
Straight adapters must be made in two versions:
- performance 1 – hell. 1
- performance 2 – hell. 2
Material:
- straight adapter – titanium alloy VT3-1;
- compression nut – 13Х11Н2В2МФ-Ш.
Maximum operating and ambient temperature for straight adapter – 300 oS.
Coating:
- straight adapter – anodic oxidation (An.Ox.2-3);
- compression nut – chemical passivation carried out in our own electroplating shop.
An example of the name and designation of a direct adapter version 1 with a compression nut to a pipeline with an outer diameter Dn = 10 mm and Dн1 = 6 mm from VT3-1:
Straight adapter with compression nut 1-10-6-OST 1 13838-81
Product applications
Straight adapters with ferrule nuts are used in many industries. An increased demand for products, in particular, is observed in the aircraft industry, where such adapters are used for reliable connection of pipelines along the outer cone in liquid and gas systems of aircraft (helicopters).
