The following perspectives must be taken into account in the determination of pipe center distances:

a) Latimea podului de conducte, latimea traverselor, etc.

a) Pipe bridge width, sleeper width, etc.

b) Dimensiunile de proiectare a conductelor, luand in calcul reazemele, grosimea straturilor de izolatie, flanse, armaturi, mecanisme de actionare, bratari, etc.

b) Design dimensions of the pipes, in consideration of pipe supports, insulation layer thicknesses, flanges, valves, drives, pipe clamps, etc.

c) Dilatatia termica pe directia distantei dintre conducte. c) Thermal expansion in the direction of the distance in question

2.0 PRINCIPII 2.0 PRINCIPLES Dimensiunile conductelor, ale partilor componenete de conducte, ale bratarilor de conducte si ale straturilor de izolatie, care sunt determinante pentru stabilirea distantei dintre axele conductelor, se vor stabili conform normelor relevante, aflate in vigoare.

The dimensions of pipes, pipe parts, clamps an insulation layers that factor into the pipe center distance must be taken from the relevant standards.

2.1 Traductoare de presiune diferentiala 2.1 Differential pressure producers Daca pe conducte sunt montate traductoare de presiune diferentiala, distanta dintre axul unei conducte si conductele invecinate va fi marita in mod corespunzator, in functie de stuturile de priza necesare (Norma Petrom OMV K 3412) si de organele de inchidere ale diafragmelor de masura (Norma Petrom OMV K 3416).

If differential pressure producers are built into the pipelines, the pipe center distances to the adjacent pipelines must be increased correspondingly due to the necessary bleeder connections (Petrom OMV standard K 3412) and measuring diaphragm shut-off elements (Petrom OMV standard K 3416).

La conductele de abur, pentru medii rezultate din condensare sau medii cu vascozitate ridicata, in dimensionarea distantelor dintre axele conductelor se va tine cont si de vasele de compensare (Norma OMV K 3415) sau de vasele de separare (Norma OMV K 3413), montate intre stuturile de priza si organele de inchidere a diafragmelor de masurare.

For steam lines, lines with products that condense out or highly viscous products, the equalization vessels (OMV standard K 3415) or separating vessels (OMV standard K 3413) inserted between the bleeder connections and the measuring diaphragm shut-off elements must also be taken into account in the dimensioning of the pipe center distances.

Pozitionarea traductoarelor de presiune diferentiala in conducte se va face conform Normei Petrom OMV K 1311.

The positioning of the differential pressure producers in the pipelines must be taken from Petrom OMV standard K 1311.

3.0 TABEL DISTANTE INTRE AXELE CONDUCTELOR

3.0 TABLE FOR PIPE CENTER DISTANCES

3.1 Distanta intre conducte Distanta intre axe la conducte neizolate si conducte fara armaturi (de ex. flanse etc)

3.1 Pipe distance Pipe center distance for non-insulated pipelines and pipelines without built-in parts (e.g. flanges, etc.)

Tabelul de mai jos a fost intocmit cu o distanta intre conducte de 75 mm. Nu trebuie sa inregistrati valori sub aceasta distanta. Distanta de 30 mm este cota minima pentru piesele (tronsoanele) invecinate si trebuie respectata intocmai, fara valori mai mici decat aceasta.

The following table was determined with a pipe distance of 75 mm. This pipe distance may not be less than this minimum. The distance of 30 mm represents the minimum dimension for the approaching parts and must be upheld.

3.2 Distanta intre conducte Distanta intre axe la conducte izolate si conducte cu armaturi

3.2 Pipe distance Pipe center distance for insulated pipelines and pipelines with installed parts

Distanta "A" intre axele conductelor se determina din dimensiunile individuale aferente (distanta minima, raza exterioara a conductei (1/2 diametrul exterior), grosimea stratului de izolatie, raza exterioara a flansei (1/2 diametrul exterior) etc. Oricum, pentru distanta intre conducte nu trebuie sa inregistrati valori sub 75 mm (vezi Fig.2).

The desired pipe center distance "A" is determined from the respective individual dimensions (minimum distance, half pipe outer diameter, insulation thickness, half flange outer diameter, etc.). However, the minimum pipe distance of 75 mm must still be met (see Fig. 2).

Pag / Page 5 Norma Petrom OMV H 1201 / Petrom OMV Standard H 1201

Daca unele piese de conducta, ca de ex. flansele, sunt prevazute cu izolatie, atunci distanta minima intre capacul flansei si conducta invecinata trebuie sa nu fie mai mica de 50 mm (vezi Fig.3).

If pipeline parts, such as flanges, are insulated, the smallest distance of the flange cap to the adjacent pipeline may not be less than 50 mm (see Fig. 3).

4.0 DILATATIA TERMICA 4.0 THERMAL EXPANSION O conducta care, sub influenta temperaturii min. si max. de functionare (TB), se poate deplasa din punctul fix pe directia distantei dintre axele conductelor, va trebui sa fie supusa calculelor de dilatatie.

A pipeline that can move from the fixed point in the direction of the pipe center distance due to the max. and min. operating temperature (TB) must be calculated for expansion.

Se aplica urmatoarele formule : The following applies: X = A + k X = A + k k = L . . TB k = L . . TB A = valoarea calculata a distantei dintre centrele conductelor (mm)

A = Calculated value of the pipe center distance (mm)

k = dilatarea conductei (mm) k = Expansion of the pipe (mm) = coeficient de dilatare liniara (mm/m . 100 Grade

Celsius) / (cca.1,2 mm/m . 100 Grade Celsius = Length expansion coefficient (mm/m . 100 Grad

Celsius) / (approx. 1.2 mm/m . 100 degrees Celsius)

La conductele care se pot deplasa in directii opuse, calculul va include X = A + 2k .

Pipes that can move in opposite directions must be calculated with X = A + 2k.

Fig. 4 Fig. 4

Exemplu: Example: L = 8m, A = 510 mm, TB = 300 Grade Celsius L = 8m, A = 510 mm, TB = degrees Celsius k = L TB = k = L TB =

= 28,8mm3001001,28 = = 28.8mm300

1001.28 =

X = A + k = X = A + k =

= 510 + 28,8 = 538,8 mm => rezulta 540 mm = 510 + 28.8 = 538.8 mm => implemented 540 mm
