FIELD: process engineering.
SUBSTANCE: invention relates to oil-and-gas industry and can be used for sealing of thread joints operated at high pressure and subjected to expansion in cross-section. This sealant comprises fibrous substrate in amount of 20-40% as hemp or linen, sealing filler in amount of 30-50% as clay powder, antifriction filler composed of surfactant making the rest.
EFFECT: high tightness of threaded joint at 23% expansion.
