SPLICING CROSS PIPE

The following instructions should be followed, when

required, to join more than one section of cross pipe

together to ensure bonding is maintained throughout the

system.

A. ALLIED MECHANICAL TUBING SPLICES

Mechanical tube splices shown in the table below shall be

of equivalent Allied Flowcoat or Gatorshield zinc coating.

Insert splice tube 6” into rst section of cross pipe and se-

cure with 2 self-drilling screws (1/4”-14 x ¾”), spacing them

approximately 1.25” from end of pipe and approximately

3.50” apart, tightening screws to 9 ft-lbs.

Slide second section of cross pipe over splice tube and

secure with two more self-drilling screws. Tighten screws

to 9 ft-lbs.

B. SCHEDULE 40 PIPE SPLICES

Use galvanized threaded pipe couplings that match the

pipe size used for the structure. Threaded Schedule 40

pipe must be used when splicing cross pipe together.

Fully thread coupling onto both sections of pipe being

spliced together.

Þ To ensure structural integrity of cross pipes, mechanical tube or

coupling splices are not permitted in end spans or in middle 1/3 of

interior cross pipe spans.

C. CROSS PIPES CAN BE JOINED OVER AN INTERIOR

TOP CAP WITH A MAXIMUM GAP OF 1/2”

Þ To avoid potential problems from the effects of thermal

expansion, a maximum total continuous cross pipe length

of 100 ft is recommended.
