Random Section of GOST 12.2.016-81

2.2. Safety requirements for driven elements.

2.2.1. Physical or chemical properties of the materials of compressor equipment essential driven elements shall not be subject to change by the impact of compressed gas and cooling fluids.

2.2.2. Windows and apertures in exterior surfaces of gas compressor equipment sub-assemblies, necessary for assembly, installation, testing, inspection, and adjustment of moving parts and piston-cylinder assemblies, dangerous for operating personnel, shall have safely closing hatches, covers, plugs, or enclosures.

(Revised Version, Rev. No. 1).

2.2.3. Threaded joints of moving sub-assemblies of compressor equipment driven elements shall have arresting devices to prevent spontaneous unscrewing.

2.2.4. Manual cranking of the compressor shaft or the use of a barring gear shall be provided as per GOST 24444-80 for inspection of the motion mechanism working order and for adjustment of compressor equipment driven elements position.

2.2.5. Compressor equipment shall have pressure relief devices for starts and stops of the driving motor.

2.2.6. Design of compressor equipment main bearings of the main shafts (rotors) shall allow for free axial displacement of the shaft caused by expansion in operation.

2.2.7. Design of compressor equipment piston-cylinder and moving assemblies shall enable monitoring and adjustment of linear clearance areas in the cylinder compression chambers.

2.2.8. To allow for free elastic and thermal displacement, horizontally arranged cylinders of large PD compressor should be provided with sliding or swinging mountings.

2.2.9. Cylinder design shall allow for free thermal displacement of its hub.

2.2.10. Design of heat exchangers comprised in a compressor plant shall ensure thermal expansion compensation of the case and individual components of such exchangers.

2.2.11. Pipelines and manifolds design shall ensure their thermal expansion self-compensation (where required, expansion absorbers should be used). Gland expansion absorbers are not recommended for use.

2.2.12. Lubricating oils and fluids used for lubrication of compressor equipment driven elements (cylinders, gland seals of PD compressors, friction assemblies of centrifugal compressors etc.), shall retain their properties in the compressed gas environment. Materials requiring no lubrication may be used for sealing.

2.2.13. Regulating and/or bypass valves shall be installed on pressure lines of the moving assembly circulating lubrication system to adjust oil pressure. Each line of oil supply to cylinders and glands shall be provided with a check valve. The lubrication system design shall ensure availability of oil (lubricating fluid) at all points of lubrication prior to the compressor start. General safety requirements for lubrication systems shall be as per GOST 12.2.040-79.

2.2.14. The design of compressor housings serving as a sump for oil of the moving assembly lubrication system shall prevent oil spillage at pressure rises in the housing cavity.

2.2.15. Compressor sub-assemblies design shall prevent lubricating oil spillage to the foundation and the maintenance platform.

2.2.16. Compressor equipment lubrication system design shall prevent contact of cooling fluid with compressed gas, except for compressors that are cooled by fluid injection into the compression cavities.

2.2.17. Design of sub-assemblies of the fluid cooling system shall include devices ensuring fluid drainage from the cooling cavities.
