Field Test pressure for pipe line

No. MJP/QCC/TB/ 322 Date 31/12/1997

TECHNICAL CIRCULAR

After laying and jointing any pipe line, the pipe line must be pressure

tested to easure that pipes and joints are strong enough to withstand the

maximum pressure likely to be developed under working condition. In this

respect G.O.I. Manual on water supply and Treatment (IIIrd Edition March

1991) describes the field test pressure to be imposed on pipe lines. In this

respect, for different types of pipes concerned paras from this manual are

as follows.

-----------------------------------------------------------------------------------------------------------

S.N. Type of pipe Page No. Page No.

----------------------------------------------------------------------------------------------------------

1. M.S. pipe Para 6.5.2 As per Para 6.4.4.2

2. Ductile Iron pipes Para 6.5.2 As per Para 6.4.4.2

3. Concrete pipes Para 6.8.3 As per Para 6.4.4.2

4. Prestressed pipes Para 6.9.3 As per Para 6.4.4.2

5. P.V.C. pipes Para 6.10.5 As per Para 6.4.4.2

6. C.I. pipe Para 6.4.4.2 As per Para 6.4.4.2

-------------------------------------------------------------------------------------------------------

Thus, for above 6 types of pipes, field test pressure is as per para 6.4.4.2.

As per this paragraph the field test pressure to be imposed should be not

less than the maximum of the following.

a) 1.5 times the maximum sustained operating pressure.


b) 1.5 times the maximum static pressure in the pipe line

c) Sum of maximum sustained operating pressure and the maximum

surge pressure.

d) Sum of maximum pipe line static pressure and the maximum surge

pressure subject to a maximum equal to the work test pressure for any

pipe fittings incorporated.

Here it is to be noted specifically that, while determining the class of

pipe along with other conditions, aspect of above field hydraulic test

pressure should also be contested

Para 6.7.1 of the Manual refers to A.C. pipes lines and there is no

specific mention about field hydraulic test pressure and it is not clear

whether it should be as per para 6.4.4.2 or not. Hence there were

doubts in the minds of some field officers about field hydraulic test

pressure of A.C. pipe line. It is also seen that the idea of operating

pressure and working pressure is also not very clear in the field. Hence

these points are clarified as under.

About working pressure, it is clarified that working / operating pressure

is the maximum sustained internal pressure, excluding the one coming

in abnormal conditions such as surge (water hammer) to which the

pipe line may be subjected to when in use. When we consider A.C.

pipe lines as Gravity Mains, then maximum internal pressure occurs

when water in tank is at the F.S.L. (Full supply level of full tank level)

and the sluice valve, located at lowest level in the section under

consideration, Is in closed position. In such case, the static head i.e.

the difference between the F.S.L. of source and lowest invert level of

pipe line in that section, is the maximum, head in that section. Thus

here as for as test pressure and class of pipe is concerned maximum


operating pressure is the static pressure. When we refer to I.S. 6530/

1972, the field hydraulic test pressure for A.C. pipe line should be 1.5

times the operating pressure and as explained about, considering the

definition of operating pressure A.C. pipe Gravity main should be

tested for 1.5 times the operating pressure i.e. for 1.5 times the static

pressure. In other words, this is the condition given in G.O.I. Manual

para 6.4.4.2 for gravity mains. For deciding the class of A.C. Gravity

main, maximum static pressure shall not exceed 50% of pressure

defining class of pipe 9Ref. App. 6.4)

All the field tests should be carried out for the pressure as clarified

above only.

Single we are not using A.C. pressure pipes for large/ long rising

main no mention of A.C. pipe rising mains is made in the above

circular.
