After the air has been expelled and the valve or valves segregating the part of the system under test have been closed, pressure is then normally applied with a hand pump, gasoline-powered pump, or fire department pumping equipment for large lines.

After the main has been brought up to test pressure, it is held at least two hours and the make-up water measured with a displacement meter or by pumping the water from a vessel of known volume.

The hydrostatic pressure test helps to identify damaged or defective pipe, fittings, joints, valves, or hydrants, and also the security of the thrust restraint system. A: Yes. Section 4. Repair is achieved by first cutting out the defective or damaged lining to the metal so that the edges of the lining not removed are reasonably perpendicular to the pipe wall or slightly undercut. A stiff mortar is then prepared, containing not less than one part of cement to two parts of sand, by volume.

This mortar is applied to the cutout area and troweled smooth with adjoining lining. To provide for proper curing of patches by preventing too rapid of a moisture loss from the mortar, the patched area is normally seal-coated immediately after any surface water evaporates, or alternatively the area is kept moist e. Of course, in potable water-related applications, no patch or curing components should be used in the repair that would negatively affect health or water quality.

A: No. Casing pipes should normally be 6- to 8-inches larger than the outside diameter of the Ductile Iron Pipe bells. Insulating chocks, skids, or spacers normally should be placed on the Ductile Iron Pipe carrier pipeor affixed to the casing, to ensure approximate centering of the carrier pipe within the casing pipe. In order to further stabilize the Ductile Iron Pipe, normally the area between the casing pipe and the carrier pipe is partially filled with sand or grout.

If the annulus is completely filled, it can be argued that external loads might understandably be transferred to the carrier pipe. If restrained joints are needed to resist thrust forces on a Ductile Iron Pipeline for example, to anchor unblocked bends immediately outside the casingand the required restrained length extends into a casing pipe, it would then be necessary to install restrained joint pipe into, and often extending completely through, the casing pipe.

In normal buried service, the function of restrained joint pipe is to transfer thrust forces to the soil structure. Therefore, if the annular space between the two pipes is not grouted, the length of restrained pipe inside the casing should not normally be considered as part of the restrained length in a thrust calculation to balance the thrust force.

Of course, if effectively designed thrust blocks are utilized to restrain thrust forces outside a casing, such thrust forces would not pull axially on joints through a casing pipe. Ductile Iron Pipe can, and has been used for both directional drilling and microtunneling installations. The methods involve forming a hole a little larger than the outside diameter of the pipe joint. The Ductile Iron Pipe is then pushed or pulled through the hole. When the pipe is pulled into position, restrained joints are utilized.

Also, specially designed and manufactured Ductile Iron Microtunneling Pipe is currently available. Consequently, the bell sockets are different and the gaskets are not interchangeable. Proper gaskets for both designs are readily available. Therefore, the direction of the bells is not functionally related to the direction of flow within the main. It is common practice — but not mandatory — to lay pipe with the bells facing the direction in which work is progressing. When the main is being laid up a slope, for example, the pipe is frequently laid with the bells facing uphill for ease of installation.

A: Not necessarily. Additionally, possible damage might occur to valves and appurtenances that may be rated at lower pressures. For an example, assume a inch Ductile Iron Pipeline is to operate at psi working pressure.

In addition, C states that the test pressure shall not exceed pipe or thrust restraint design pressures. For inch diameter Ductile Iron Pipe, the lowest pressure class available is psi. A specification calling for a test pressure of 1.This standard describes stainless-steel, ring-type, slip-on flanges and blind flanges for use in conjunction with stainless-steel pipe used in facilities of waterworks service.

This standard covers installation procedures for ductile-iron mains and their appurtenances for water service. Installations that require special attention, techniques, and materials are not covered. Each such installation requires special considerations based on many influencing factors and cannot be covered adequately in a single standard.

This type of installation can best be accomplished by a competent engineering design in consultation with representatives of the material manufacturing industry. Some of these installations include the following: Piping through rigid walls; Piping on supports above or below ground; Piping requiring insulation; Treatment plant or pump-station piping; Industrial piping; Piping through geologically hazardous areas; Piping in high-density-stray-current environments; Piping through corrosive soil; and Piping through unstable soil.

I kknow that AWWA Standard C was replaced in by C, does anyone have a copy of the previous standard and if so can you tell me what the section regarding hydrostatic pressure testing of the main required?

Thanks in advance. The formulae look drastically different, until one realizes the most common type of pvc pipe in the USA is gasketed joint and in 20 feet lengths, and if you multiply the denominator of the equation by 20 you will in fact get thedenominator value of the current where "N" has been replaced by "L". In practical terms, very likely close to the "same difference". Hope this helps, and as I unfortunately do not have the version, I will like you await more learned comment.

I was able to obtain a copy of the old standard, C It reads as follows in " 7. The hydrostatic pressure shall not be less than 1. The hydrostatic test pressure shall not be less than 1. However, in no case shall the test pressure exceed the rated working pressure for any joint, thrust restraint, valve, fitting, or other connected appurtenance of the test section.

Thanks for your thoughts on this. It seems like more and more words are being added to some hydrostatic testing specifications. That list now includes, " System design pressure, required test pressure, and test duration Sec.

This edition approved June 6, The testing methods described in this section are specific for water-pressure testing.

These procedures should not be applied for air-pressure testing because of the serious safety hazards involved. Use of a test pressure greater than the rated valve pressure can result in trapped test pressure between the gates of a double-disc gate valve.

For tests at these pressures, the test setup should include a provision, independent of the valve, to reduce the line pressure to the rated valve pressure on completion of the test. The valve can then be opened enough to equalize the trapped pressure with the line pressure, or fully opened if desired.

After the pipe has been laid, all newly laid pipe or any valved section thereof shall be subjected to a hydrostatic pressure of at least 1. Each valved section of pipe shall be slowly filled with water, and the specified test pressure based on the elevation of the lowest point of the line or section under test and corrected to the elevation of the test gauge shall be applied by means of a pump connected to the pipe. Valves shall not be operated in either the opening or closing direction at differential pressures above the rated pressure.

It is good practice to allow the system to stabilize at the test pressure before conducting the leakage test. Before applying the specified test pressure, air shall be expelled completely from the section of piping under test.

If permanent air vents are not located at all high points, corporation cocks shall be installed at such points so that the air can be expelled as the line is filled with water.

At the conclusion of the pressure test, the corporation cocks shall be removed and plugged or left in place as required by the specifications. All exposed pipe, fittings, valves, hydrants, and joints shall be examined carefully during the test. Any damage or defective pipe, fittings, valves, hydrants, or joints that are discovered following the pressure test shall be repaired or replaced with sound material, and the test shall be repeated until satisfactory results are obtained.

Leakage shall be defined as the quantity of water that must be supplied into the newly laid pipe or any valved section thereof to maintain pressure within 5 psi Leakage shall not be measured by a drop in pressure in a test section over a period of time.

These formulas are based on an allowable leakage of Acceptance shall be determined on the basis of allowable leakage. If any test of laid pipe discloses leakage greater than that specified in Sec. Learn more about Scribd Membership Home.
