METHOD OF MOUNTING OF PETROLEUM PRODUCT SUPPLY HARDWARE CONNECTORS Russian patent published in 2008 - IPC F16L37/00 

FIELD: mechanics.

SUBSTANCE: invention relates to the production and operation petroleum product supply hardware split joints incorporating flexible sealing elements. Prior to placing the elastic sealing element on the circular grooves, an elastic barrier layer is formed all along its surface from the material with brittle temperature not exceeding minus 60°C and petroleum product permeability at (70±2)°C not over 10 g/m per a day. The barrier layer thickness is selected from the following relation (H=K·D_nom·10^-4), where H is the elastic layer thickness, D_nom is the nominal bore of the connector, K=3÷5 is the tightness factor for various values of the flange connection and hydro pneumatic grip D_nom , K=6÷10 is the tightness factor for various D_nom values of the faucet connection and mechanical grips, K=20, 35 is the tightness factor for D_nom of the threaded joint making 0.025 and 0.040, respectively. The invention allows increasing the efficiency of the petroleum product supply hardware split joints, decreasing costs of petroleum leaks liquidation.

EFFECT: higher reliability of joints along with higher ecological safety of the petroleum product supply hardware split joints operation.
