OST 1 13861-81 Thrust crosses with compression nuts
Cross according to OST 1 13861-81 – the design feature is a compression nut (made of 30KhGSA steel) and made of aluminum alloy.
Description of product design features
Material:
- through cross – aluminum alloy AK4-1;
- compression nut – steel grade 30HGSA.
Maximum operating and ambient temperature for the through-cross – 150 oS.
Covering crosspieces with anodic oxidation (An.Oks.tv10-15), crimp nuts with cadmium (Kd6.fos.oks.gfzh) is carried out in our own electroplating shop.
An example of the name and designation of a crosspiece with a compression nut to a pipeline with an outer diameter Dn = 10 mm from aluminum alloy:
Thru cross with compression nut 10-OST 1 13861-81
Product applications
Frogs with compression nuts are used in many industries. An increased demand for products, in particular, is observed in the aircraft industry, where such crosses are used for reliable connection of pipelines along the outer cone in liquid and gas systems of aircraft (helicopters).
