GOST 9567-75 is the Russian standard for high precision seamless steel tube. It is specified where the dimensional tolerance is tighter than ordinary GOST 8734 pipe, for example in hydraulic and precision machined parts.
What it covers
- High precision outside diameter and wall dimensions
- Seamless cold deformed tube
- Material grade taken from the technical conditions standard
Relation to other standards
- GOST 9567-75 is the precision dimension series
- GOST 8734-75 is the general cold deformed series
- DIN 2391 is the European equivalent buyers often compare it to
Applications
- Hydraulic cylinder barrels
- Precision machined parts
- Measurement and instrument components
Frequently asked questions
What is the difference between GOST 9567 and GOST 8734?
GOST 9567-75 gives tighter dimensional tolerances for precision tube, while GOST 8734-75 is the general cold deformed pipe series.
Is GOST 9567 the same as DIN 2391?
