components retrieval”
application of nonflammable materials for heat- and sound insulation of
pipelines and the equipment;
equipping of the technological equipment by all necessary control devices,
automatics, safety valves (drain, back valves, etc.), providing reliability
and trouble-free operation;
remote control of tap valves on the main gas pipeline, tap valves on the
candles of pressure dumping in head gas pipelines;
emergency lighting with supply by batteries;
application of explosion-proof equipment for explosive zones;
gas pipeline protection from electromagnetic induction, static electricity, and
measures for prevention of high potentials bringing in buildings;
usage of steel seamless pipes for gas pipelines and other technological
pipelines with obligatory hydraulic test of each pipe at the factory of
origin;
usage of welded connections on gas pipelines and pipelines with explosivefire-hazardous
and toxic substances;
usage of shaped connections of pipelines (taps, tees, adapters) of the factory
manufacturing, checked up and tested at factory;
identification coloring of gas pipelines and other technological pipelines.
With a view of protection of the personnel from thermal effect, the hot surfaces of the
equipment and pipelines in the service area have a heat insulation providing temperature of hot
surfaces in permissible by norms sanitary limits.
Sewage waters
Industrial sewage waters discharge is made in designed on CGTU sewerage
network and further in ponds-evaporators. Household flows are discharged in rakings.
Protection of land resources
The construction organizations should reduce as much as possible use time of the
lands, occupied under temporary using, strictly observe norms of duration and terms of
lands restoration carrying out (under construction of the connecting gas pipeline and
condensate line).
Lands restoration is included in the general complex of works on construction of
pipelines and is carried out in following sequence:
- stripping of the soil fertile layer and its removal to temporary spoil.
- construction of pipelines (earth, insulation-packing works, etc.)
- distribution of surplus of the mineral ground which has remained after
tranches filling, throughout restoration zone.
- clearing of rubble and debris.
- backspacing from the temporary spoil of the sfl and its uniform distribution
within restoration zone.
