Preface
Shimla is a historic hill top city and capital of the Himachal Pradesh. It has an average altitude of 2,206 meters above mean sea level. There are no water bodies near the main city and the closest river, the Sutlej, is about 21 km away. Due to water scarcity, people faced hardship in getting drinking water, thus there is a water crisis in the city. Despite acute water scarcity, water infrastructure is too old. Most of the distribution pipelines are laid during British era, as a result the Non-revenue water (NRW) level is high and there is no consumer satisfaction. With an aim of increasing drinking water availability to the city and improving service level, Shimla Municipal Corporation (SMC) has a planned a comprehensive water supply project. Government of Himachal Pradesh (GoHP) has incorporated this scheme in AMRUT program aided by the World Bank. To begin with, a 24x7 water supply scheme has been suggested in three Demo areas of Sanjauli1, Sanjauli2 and Totu. Design of distribution system of these demo areas has been submitted. As the pressures in the pipelines are very high, it is necessary to provide strong pipes to sustain the pressures. Hence, design of pipe thickness has been carried out which is submitted in this report.

Design Procedure
Design of M.S. Pipe for Internal Pressure The thickness of pipe shell is required to be checked to withstand internal pressures. The internal pressure for which the pipe thickness is required to be checked which should be the maximum of the pressure for the three conditions given below:
1. 1.5 times working pressure 2. 1.5 times maximum static pressure 3. Maximum operating pressure plus pressure due to water hammer.
Field Conditions Following field conditions are considered:
• Since flow in entire distribution pipe network is by gravity, water hammer pressure is not considered. Hence, only above conditions of (1) 1.5 times working pressure and (2) 1.5 times maximum static pressure are considered and the maximum pressure shall be the maximum of these two conditions.
• It is assumed that the pipelines are laid above ground level on RCC chairs. Design of
the chairs shall be such that the deflection shall not be more than the permissible value. It is strongly suggested that the spacing between the two chairs should not be more than 5m. Proper expansion joints shall be provided.
Analysis of Results From pipe results provided in Volume II, maximum pressure acting on each pipe in demo zone is known which is considered in the design. These pressure are increased to 1.5 times as per above conditions of internal pressure, so the maximum pressure for which pipes are to be designed is computed. The analysis is made for two cases, (i) pipes with Pressure reducing Valves (PRVs) and (ii) pipes without PRVs. The pressures will be maximum for the demand of the year 2020 and without considering the peak factor. Hence, analysis is carried out for the two cases- (a) Pipe results with PRVs, with demand of 2020 and without peak factor of 3 and (b) Pipe results without PRVs with demand of 2020 and without peak factor of 3. The two tables with results are shown in Appendix. The pipe material, diameter and thickness are shown in Table (b).

Procedure (1)Minimum Thickness: As per IS 3589 : 2001, Edition 4.2, the minimum thickness of the M.S. Pipe line shall not be less than the thickness’’, worked out by the formula given below.
2
PDT
S=
Where: P = Internal design pressure in Mpa D = Diameter of pipe in mm (O.D.) S = axfxe a = Design factor = 0.6 for working pressure = 0.9 for test pressure f = minimum yield stress in MPa = 235 MPa for Fe 410 e = Weld efficiency = 0.8 to 0.9
Corrosion Allowance: Corrosion Allowance of 1.5 mm has been considered in the design. Check for minimum wall thickness: If D/t ratio is less than 300, minimum wall thickness computed as above is correct.
(2)Hydraulic Pressure Test (Factory Test) As per IS 3589, each pipe shall be hydraulically tested at the manufacturer’s works before the pipe is coated, wrapped and lined. The maximum test pressure to be limited to 5 MPa wherever applicable.
(3)Vacuum Design:-
Under certain conditions of operations, water may get removed from some section of pipeline faster than it can be supplied from the source. Such condition may occur as a result of valve operation (sudden full opening of scour valve) or draining of pipe /rupture of pipe at a point at low level. If at such locations the pipe is exposed to atmosphere and the thickness of the pipe is small, air must be admitted into the pipe to prevent an excessive reduction of the internal pressure and the subsequent collapse of the pipe throughout in portion of its length because of external atmospheric pressure.
-

The resistance of an exposed pipe to vacuum pressure depends on thickness to diameter ratio. As per American Practice (Errata of M11 Code), the critical collapsing pressure of mild steel pipe can be calculated as under:
3
66,000,000ct
Pd
=
Where t = thickness in inch And d = diameter in inch Pc= Collapse pressure in psi The pressure obtained shall be converted to kg/cm2 by the relationship 1 psi = 0.070307 Kg/cm2
Also as per I.S. 5822 – 1970, the pipe thickness shall be strong enough to withstand partial vacuum corresponding to two third of the atmospheric pressure, which may occur with in the pipe. This means the Pc shall be greater than 0.34 kg/cm2.
(4)Design Scenario As terrain is hilly, huge pressures are encountered. Pipe thickness shall be strong enough to withstand pressure at worst condition. Such condition shall be when the pipes are subjected to the demand of the year 2020 and the PRv are inactive (fully open). Hence, the thickness of pipes have been computed for this condition and are shown in Tables 2 to 13 in Appendix.
(5)Summary of Pipes Required Summary of Pipes Required is shown in Table 1.
