174. On pipelines of dangerous chemicals, the shutoff valves allowing to disconnect both all pipeline, and its certain sites from the working technology systems, to establish caps and to provide possibility of emptying, washing, purge and testing for durability and hermeticity of pipelines are established.

175. All shutoff valves, the backpressure and safety valves before installation are subjected to check and hydraulic test for mechanical durability and hermeticity. Results of testing are registered in the magazine.

176. Safety valves before their start-up in operation are regulated at the stand on working pressure and sealed up. Loads of lever safety valves are fixed and fixed.

177. The locking and regulating armature established on pipelines is located in places, available to servicing. In case of armature arrangement at meter 1,8 height for its servicing platforms and ladders are provided. The armature intended for frequent opening and closing it is not allowed to have above meter 1,6 from the level of floor or the platform.

178. Use of adjusting valves as shutoff valves is not allowed.

179. Pipelines in which release of condensate is possible are supplied with kondensatootvodchik for its removal. Steam lines in order to avoid water hammers and vibration are performed with bias.

180. Laying of pipelines of pozharovzryvoopasny hazardous and caustic substances through household, utility and administrative rooms, distributing devices, electrorooms, rooms for KIP and air-ventilation chambers is not allowed.

181. For the pipelines passing through walls or overlappings of the building steel sleeves from pipes which internal diameter is 10 - 20 millimeters more than the outer diameter of pipelines are provided (taking into account thermal isolation). The gap between the pipeline and sleeve since both ends is filled with the fireproof material allowing movement of the pipeline along its longitudinal axis.

182. Pipelines are located so that the possibility of their damage by the moved loads or vehicles was excluded.

183. Laying of pipelines of acids and alkalis on outside walls of the buildings which are not connected with the address of acids and alkalis through auxiliary, utility, administration and household rooms is not allowed. In places of crossing iron and highways, pedestrian passes pipelines consist in the trench with withdrawal of leakages of acids and alkalis to the safe places determined by the project.

184. To the pipelines transporting acids and alkalis it is not allowed to fix other pipelines (except the heat tracers fixed without welding).

185. In case of transportation of chemicals through pipelines for prevention of hardening (crystallization) laying of outside pipelines with heat tracers and heat insulation of pipelines is provided.

186. In places of movement of people and transport (over roads, drives, transitions) the pipelines having flange connections and transporting aggressive liquids are performed with the closed casings and consist in trenches with removal of aggressive liquids to the safe place.

187. The pipelines for transportation of acids and alkalis laid on platforms are protected from mechanical damages, including:

from the falling objects (the arrangement over the pipeline of lifting devices and the easily dumped canopies is not allowed);

from possible blows from vehicles for what the pipeline have on removal from dangerous sites or separate from them barriers;

in case of multilevel laying pipelines of acids and alkalis to have on the lowermost tiers.

188. For the pipeline of acids or alkalis laid out of the territory of the companies the conservation zone at least 2 meters wide from each its party within which implementation of works without approval and control from the representative of the organization operating the pipeline is not allowed is provided.

189. Amounts and terms of carrying out audit of pipelines, shutoff valves and safety valves are carried out according to requirements of Security guidelines in case of the operation of technology pipelines approved by the order of the Minister of Emergency Situations of the Republic of Kazakhstan of July 27, 2021 No. 359 (it is registered in the Register of state registration of regulatory legal acts at No. 23754) (further - Security guidelines in case of operation of technology pipelines).

190. On pipelines hermetic shutoff valves are applied. Constructional materials of armature approach from stability conditions the transported circle and ensuring operation of armature in the admissible range of parameters of the circle.

191. All locking cranes are provided with designation of provision of stopper of the crane in the form of the line which is sawn through on its face part and painted by white paint. The provision of gates and shiber designate by means of cuts on the face parties of axis. Automatic splitters are supplied with indexes of extreme provisions ("Is open", "closed").

If by the methods stated above it is impossible to designate provision of traffic jams of cranes and locking devices, the arrows indexes or texts designating their provision are applied.

192. It is not allowed to make repair, adjustments and cleaning of the devices, pipelines, mechanisms and armature which are under pressure, in case of high temperature, filled with liquids and not exempted from technology gas, or on the run.

193. Works at height on dismantling, installation of pipelines and the equipment make from the woods or stage with handrail and onboard barrier.

194. On the pipelines giving combustible substances to fire chambers for burning the cutting valves automatically blocking supply of fuel in fire chambers in case of blackout of flame, the termination electro-pneumo - food of control and measuring and automatic devices of fire chamber are established.

195. In the presence of viewing glasses for observation of circulation of liquid in devices and pipelines, glasses are equipped with protective grids and "illumination".

196. Use of active pipelines for fixture of blocks, scaffolding and ladders is not allowed.

197. Places of transition via pipelines are equipped with metal ladders (bridges) with bilateral handrail.

198. Sanitary and technology pipelines are not allowed to be passed through electrorooms, premises of complete and transformer substations (further - KTP).
