locatesd in the cities and other populated areas, should be prcvicied

for use/application as tne systeas of the centralized gas supply cn

should be set in the project ct gas supply cc the basis of

DOC = 30042801 F&GS 10

coni-ions.

In the systems of gas supply it is to accept the following

categories of the gas FrXessure:

low - at a pressure of gas is not acre than 0.05 kg/c.z;

average - at a pressure ct gas is acre than 0.05 to 3 kg/ca2;

high - at a pressure of gas is more than 3 to 6 kg/cmz;

high - at a pressure of gas as more than 6 to 12 kg/cm2.

2.2. Vith centralized gas su~ply can be used following

distribution systems of gas:

a) single-stage, and witn supply of gas to users only according

to gas pipes of one, as a rule, cf low pressure;

b) two-stage, witi gas sufily to users cn gas pipes of two

Fressures - average and lcv or kagh to 6 kg/¢c2 and low;

c) three-stage,.vitk gas supply by users on gas pipes of three

pressures - high to 6 kg/cm*. average and low;

d) multistage, with which the distributicu of gas is

accouplished/realized by gas pipes of four pressures: high to 12

kg/cm2. high to 6 kg/cia. averages and lcw.

communications between the gas pipes of different pressures,

entering the system of gas sup ply, must be accompJlished/realized only

through the qas-regulatcz areas.

2.3. Selection of distribution system of gas should be done

depending on sizes/limenhions and ilanning of city or another

populated area, use cf Sas, azzang~aent/pcsition of residential and

industrial consumers, sizes/dineasions of gas consumption,

arrangement of sources of gas supply (gas-distributing stations, gas

plants) and physicccheuical Farazeters of gas. The solution most be

of technical-economically substantiated.

2.4. Gas-distributing staticas of main-line gas pipes must be

furnished, as it inculcated, near of gas supplied objective (city,

populated area, enterprise), gut act are nearer than distances of

those determined in acccriance with demands of chapter SNIP
