6) pressures chamber.

4. The major dangerous factors (risks) which should be avoided are:

1) unprotected mobile elements;

2) the increased noise level and vibrations;

3) exceeding of pressure (working pressure did not exceed the most admissible working);

4) fire-dangerous and explosive elements.

2. Terms and determinations

5. In this Technical regulation the terms and determinations established by the legislation in the field of technical regulation and in the field of industrial safety and also the following terms with the corresponding determinations are applied:

1) sample witness - the sample made of the same material and on the same technology as the vessel used for determination of condition of material in use;

2) the reinforced plastic - the material of heterogeneous structure consisting of plastic (binding) and filler;

3) cylinder - the vessel having one or two mouths for installation of gates, flanges or unions, intended for transportation, storage and uses compressed liquefied or dissolved under pressure of gases;

4) coil - the heat-exchanging device executed in the form of curved pipe;

5) composition material (composite) - the material of heterogeneous structure consisting of several homogeneous materials (components);

6) multichamber vessel - the vessel having two or more working cavities used under different or identical conditions (pressure, temperature, environment);

7) cap - the volume detail hermetically closing openings of the union or lug;

8) residual resource - total operating time of object from the moment of control of its technical condition before transition to limiting condition;

9) leyner - the inside pressurizing layer of vessel from the reinforced plastic bearing part of loading;

10) nonmetallic vessels - the vessels made of homogeneous or composition nonmetallic materials;

11) metalplastic vessels - multilayer vessels in which the inside layer (cover) is made of metal; other layers are made of the reinforced plastic. The inside layer bears part of loading;

12) filler - the material reinforcing plastic; as the reinforcing material use fibers, woven and nonwoven fabrics;

13) the passport - the document containing data on product characteristics and measures for ensuring safe handling of it;

14) the tank - the portable vessel which is constantly established on frame of the rail car, on the chassis of the car (trail car) or on other vehicles, intended for transportation and storage of gaseous, liquid and other substances;

15) settlement service life of vessel - the service life in calendar years estimated from the date of input of vessel in operation;

16) the permitted pressure of vessel (element) - the most admissible excessive pressure of vessel (element) established by results of engineering certification or diagnosing.

3. Product circulation conditions in the market of the Republic of Kazakhstan

6. The equipment, working under pressure, realization in the market is not subject if they do not conform to requirements of this Technical regulation and can do harm to life, health of the person and the environment.

7. The complete and reliable information given in the accompanying documentation is provided to consumers.

The accompanying documentation shall contain:

1) project documents and passport of products;

2) instruction for installation;

3) maintenance instruction.

8. Each vessel is delivered by the manufacturer to the customer with the passport (appendix 2 presents of the Technical regulation).

The operation manual is put to the passport.

On each vessel the plate is attached. For vessels with an outer diameter less than 325 mm it is allowed not to establish the plate. At the same time all necessary data are applied on the vessel case.

On the plate are put:

1) trademark or name of the manufacturer;

2) name or designation of vessel;

3) sequence number of vessel on numbering system of the manufacturer;

4) year of production;

5) working pressure, MPa;

6) settlement pressure, MPa;

7) trial pressure, MPa;

8) admissible maximum and (or) minimum working temperature of wall, hail. With;

9) mass of vessel, kg.

For vessels with the independent cavities having different settlement and trial pressure, temperature of walls specify these data for each cavity.

9. Marking is carried out according to requirements of the order of the Government of the Republic of Kazakhstan of March 21, 2008 No. 277 "About approval of the Technical regulation "Requirements to Packaging, Marking, Labelling and Their Correct Drawing".

10. The equipment working under pressure, and if necessary separate assembly units shall have the accurate and nonerasable marking executed in the state and Russian languages.

4. Safety requirements

11. For each vessel settlement service life taking into account service conditions is established and is specified in the passport.

12. The devices interfering outside and internal surveys of vessels (mixers, coils, shirts, plates, partitions), are provided removable.

In case of use of welded devices the possibility of their removal for carrying out outside and internal surveys and the subsequent installation into place is provided. The procedure for renting and installation of these devices is specified in the operation manual on vessel.

13. Vessels have the union for filling and discharge of water, for removal of air in case of hydraulic testing.

On each vessel the gate, the crane or other device allowing to exercise control of lack of pressure in vessel before its opening is provided; at the same time withdrawal of the circle goes to the safe place.

14. The vessels intended for work in the conditions of cyclic and sign-variable loadings are calculated on durability taking into account these loadings.

The design of the vessels warmed by hot gases provides reliable chilling of the walls which are under pressure up to the settlement temperature.

15. Vessels are supplied with the necessary number of the hatches and viewing hatches providing survey, cleaning and repair of vessels, installation and dismantle of folding internal devices.

16. The vessels consisting of the cylindrical case and lattices with fixed in them tubes (heat exchangers), and vessels intended for transportation and storage of cryogenic liquids, the vessels intended for work with substances of the 1st and 2nd class of danger, but which are not causing corrosion and scum it is allowed to produce without hatches and hatches irrespective of diameter of vessels.

17. Vessels with internal diameter more than 800 mm have hatches, and with internal diameter of 800 mm and less - hatches.

18. Covers of hatches are removable. On the vessels isolated on the basis of vacuum welded covers are allowed.

19. Covers weighing more than 20 kg are supplied with lifting and rotary or other devices for their opening and closing.

20. The design pivotally - folding or plug-in bolts, collars, tightening devices of hatches, covers and their flanges shall prevent their spontaneous shift.

21. In the presence on vessels of unions, flange sockets, the removable bottoms or covers which internal diameter provides possibility of carrying out internal survey it is allowed not to provide hatches.

22. Openings for hatches, hatches and unions are located out of welded seams.

The arrangement of openings is allowed:

1) on longitudinal seams of cylindrical and conic feedwells of vessels if the nominal diameter of openings is no more than 150 mm;
