Cast Iron Pipe

be measured and recorded for each change in grooving tool setup to verify

compliance with coupling manufacturer's tolerances. Grooved joints shall

not be used in concealed locations.

3.7.5

Cast Iron Pipe

Cast iron soil, waste and vent pipe joints shall be bell and spigot

compression and hubless gasketed clamped joints installed per the

manufacturer's recommendations.

3.7.6

Copper Tube and Pipe

Joints shall be made up with fittings of compatible material and made for

the purpose intended.

a.

Brazed. Brazed joints shall conform to MSS SP-73 and CDA A4015,

made with flux, and are acceptable for all pipe sizes.

b.

Soldered. Soldered joints shall be made with flux and are only

acceptable for piping 50 mm 2 inches and smaller. Soldered joints

shall conform to ASME B31.5 and CDA A4015. Soldered joints shall

not be used in compressed air piping between the air compressor

and the receiver.

c.

Copper Tube Extracted Joint. Mechanically extracted joints shall

be made in accordance with ICC IPC.

d.

Mechanical couplings may be used in conjunction with grooved tube

for aboveground, nonferrous, domestic hot and cold water systems

in lieu of unions, brazed, soldered, or threaded joints.

Mechanical couplings are permitted only in accessible locations,

including behind access plates. Designs which can only clamp on

the bottom of the groove or which utilize gripping teeth or jaws,

or which use misaligned housing bolt holes, or which require a

torque wrench or torque specifications will not be permitted.

Rigid grooved tube couplings shall be used with grooved end tubes,

fittings, and valves. Rigid couplings shall be designed for not

less than 862 kPa 125 psi service appropriate for static head plus

the pumping head, and shall provide a watertight joint. Grooved

fittings and couplings, and grooving tools shall be provided from

the same manufacturer. Segmentally brazed or soldered elbows

shall not be used. Grooves shall be prepared in accordance with

the coupling manufacturer's latest published standards. Grooving

shall be performed by qualified grooving operators having

demonstrated proper grooving procedures in accordance with the

tool manufacturer's recommendations. The Contracting Officer

shall be notified 24 hours in advance of test to demonstrate

operator's capability, and the test shall be performed at the work

site, if practical, or at an agreed upon site. The operator shall

demonstrate the ability to properly adjust the grooving tool,

groove the tube, and to verify the groove dimensions in accordance

with the coupling manufacturer's specifications.
