A.

PIPE TESTING

CONTRACTOR shall perform a pneumatic test on solid pipe and fittings greater
than 50 ft in length after placement in the trench, in accordance with the
Manufacturer’s recommendations.

Pipes shall be pressure tested in presence of ENGINEER. Provide a minimum 7
days notice to ENGINEER before performing test.

Pneumatic testing shall be performed as follows:

1. The test period at the test pressure shall last no less than 10 minutes.

2. Provide all necessary connections, bulkheads, flanges, bracing, and
blocking, as well as all required test equipment.

3. Test pressure gauges:

a. For GCCS and condensate main pipes, the test pressure gauge shall
have a maximum range of no more than 20 psig, with minor
gradations no greater than 0.1 psig.

b. For the compressed air pipe, the test pressure gauge shall have a
maximum range of no more than 200 psig, with minor gradations no
greater than 1 psig.

4. Pipe to be tested shall be exposed in the trench, except bends, reduced
pressure rated fittings and components, which shall be buried or
restrained. Flange connections shall be visible to check for leaks.

5. Test pressure:

a. For GCCS and condensate main pipes, the test pressure shall be 10
psig.

b. For the compressed air pipe, the test pressure shall be 75 psig.

6. Test shall be accepted if the pressure drop over 10 minutes is less than 5
percent of the pressure at the beginning of the test period.

Test Report

1. ENGINEER shall prepare and submit to OWNER a test report using the

attached forms for each pipe system tested. Include following information
in test report.

Date of test.

Description and identification of pipe system tested.
Type of test performed.

Test fluid.

Test pressure.

Results of test.

Type and location of leaks detected.

Corrective action taken to repair leaks.

Results of retesting.

Name of person performing test.

SECTION 15212

POLYVINYL CHLORIDE (PVC) PIPE AND FITTINGS

PART 1 - GENERAL

1.1 SCOPE OF WORK

A.

Supply polyvinyl! chloride (PVC) Schedule 80 pipe and fittings as shown on the
Drawings.

1.2 SUBMITTALS

A.

CONTRACTOR shall submit to ENGINEER manufacturer’s technical product data
and installation instructions for PVC pipe and fittings.

PART 2 - PRODUCTS

2.1 PIPE AND FITTINGS

A.

Pipe and fittings shall be manufactured from a PVC compound which meets the
requirements of Cell Classification 12454-B polyvinyl chloride as outlined in
ASTM D1784. Pipe and fittings materials shall be specially formulated with
sufficient ultraviolet screeners to provide for longer term outdoor exposure with
no deleterious effects.

PVC pipe used in the construction of landfill gas extraction well shall meet the
requirements of ASTM D1784 and ASTM D1785 for Schedule 80 PVC pipe.

PVC fittings used in the construction of landfill gas extraction well shall meet the
requirements of ASTM D2464 and ASTM D2467.

All PVC cements shall meet the requirements of ASTM D2564 for solvent
cemented PVC joints.

Clean rework or recycle material generated by the manufacturer’s own
production may be used so long as the pipe or fittings produced meet all the
requirements of this Section.

Fittings shall be industrial, heavy duty, hub style.

Socket fittings shall be pressure rated the same as the corresponding size pipe

prescribed by ASTM D1785. Threaded fittings shall be pressure rated to at least
50 percent of the rating for socket fittings.

January 2021 3066.21

PART 3 - EXECUTION
3.1 PVC PIPE HANDLING
A. PVC pipe and pipe fittings shall be handled carefully in loading and unloading.
They shall be lifted by hoists and lowered on skidways in such a manner as to
avoid shock. Derricks, ropes, or other suitable equipment shall be used for
lowering the pipe into well borings. Pipe and pipe fittings shall not be dropped
or dumped.

3.2 PVC PIPE INSTALLATION

A. PVC pipe installation shall conform to the requirements of this Section, the
Manufacturer’s recommendations, and as outlined in ASTM D2774V.

3.3. JOINING OF PVC PIPES
A. Pipes shall be joined in accordance with ASTM D2855.

B. All pipe shall be inspected for cuts, scratches, or other damages prior to
installation. Pipe with imperfections shall not be used.

C. All burrs, chips, etc., shall be removed from pipe interior and exterior.

D. All loose dirt and moisture shall be wiped from the interior and exterior of the
pipe end and the interior of the fitting.

E. All pipe cuts shall be square and perpendicular to the center line of pipe.

F. Pipe ends shall be beveled prior to applying primer and solvent cement so that
the cement does not get wiped off during insertion into the fitting socket.

G. A coating of CPS primer, as recommended by pipe supplier, shall be applied to
the entire interior surface of the fitting socket, and to an equivalent area on the
exterior of the pipe prior to applying solvent cement.

H. The solvent cement shall comply with the requirements of ASTM D2564 and
shall be applied in strict accordance with the Manufacturer’s specifications.

]. Pipe shall not be primed or solvent welded when it is raining, or when

atmospheric temperature is below 40°F, or above 90°F when under direct
exposure to the sun.

SANBORN HEAD

Specification 15212 - Polyvinyl Chloride (PVC) Pipe And Fittings Page 3 of 3
January 2021 3066.21

J. After solvent welding, the pipe shall remain undisturbed until cement has
reached initial set. As a guideline for joint setting time, use 1 hour for ambient
temperatures between 60 and 100°F, or 2 hours when ambient temperature is
between 40 and 60°F.

K. Pipe and pipe fittings shall be selected so that there will be as small a deviation

as possible at the joints, and so that inverts present a smooth surface. Pipe and
fittings that do not fit together to form a tight fitting shall be rejected.
