Providing necessary security measures at the same time is assigned to the operational organization. Necessary security measures are specified in the special instruction developed by contract organization and approved with the customer, the operational organization and the project organization. The instruction affirms contract organization to which providing necessary security measures is assigned. The gas supply in the consumer's gas pipelines in case of complex approbation of the equipment of gas distribution station is not allowed.

Gas pipelines

131. The pipes applied to trunk gas pipelines and gas pipelines of technological binding of compressor stations, gas distribution stations, gas-measuring stations, underground gas storages, and also to emergency inventory conform to requirements of these rules.

132. Pipelines of process, fuel, starting and pulse gas belong to gas pipelines of technological binding.

133. Application of the pipes and shaped connecting products which do not have certificates or other documents confirming compliance to their requirements of standards (technical specifications) and also in the absence of marking on surface of pipes is forbidden.

134. Maintenance and repair of trunk gas pipelines and gas pipelines of technological binding of compressor stations, gas distribution stations, gas-measuring stations, underground gas storages are carried out by the relevant services according to the scheduled plan approved with terms of repair of other production equipment and approved by the gas transmission organization (operator). Control of fixture of gas pipelines (the bases, support, suspenders, collars, etc.), and also vibrations and thickness of walls of gas pipelines by nondestructive methods in places, the most subject to erosive and corrosive wear is periodically exercised.

135. Frequency, procedure and amounts of control are determined by the gas transmission organizations. Welding wiring works on the gas pipelines operating or exposed to major repair are carried out according to requirements of the existing regulating documents.
