Smooth Wall HDPE   UL Listed Smooth WallSmoothWallCollage

HDPE Duct from PNA has been tested and proven under the most severe conditions from extreme temperatures to abrasive and high tension applications in underground installations. HDPE from PNA provides quality service and economy in a wide range of uses. As a smooth and flexible duct for cable, HDPE is unequaled for ease of installation and continuous strength.

With a smooth inner wall, PetroDuct™ is supplied on light weight steel reels (take-apart or solid)  which are manufactured in house or can be supplied in coils.

Smooth Wall PetroDuct™ is available pre-lubed, with pull tape pre-installed. Joints are available in all sizes.

Sizes Available: 13mm 1/2″ 3/4″ 1″ 1-1/8″ 1-1/4″ 1-1/2″ 2″ 2-1/2″ 3″ 4″ 5″ 6″

NEMA Sizes Available:  ¾”, 1”, 1-1/4”, 1-1/2”, 2”, 2-1/2”


Ribbed HDPE  RibbedCollage

For specialized installation of underground cable, including fiber optics, PetroRib™ duct provides superior friction reduction and flexibility. Manufactured from quality HDPE resin, PetroRib™ offers maximum strength and adaptability on long pulls with numerous turns and elevation changes.

PetroRib™ duct is available pre-lubed, with pull tape pre-installed. Joints are available in all sizes.

Sizes Available: 1″, 1 1/4″, 1 1/2″, 2″.


Corrugated HDPE  RUSListedCorrugated collage

For specialized installation of underground cable, PetroDuct™ corrugated duct provides excellent friction reduction and superior flexibility in tight turns. Manufactured from quality HDPE, PetroDuct™ corrugated duct is most commonly used as innerducts to create cable raceways inside of larger duct.  Our corrugated duct can also be used in aerial applications as well as many general purpose applications.

Corrugated PetroDuct™ is available in stock with pull tape pre-installed.

Standard colors: Black (UV), Blue, Orange and Green.  Additional colors available upon request (lead times and minimum order quantities will apply).

Sizes Available: 1″, 1-1/4″, 1-1/2″, 2″


Fire-Retardant HDPE  Fire Retardant

PNA offers HDPE Fire Retardant Conduit in 1″ and 1-1/4″ sizes suitable for Riser applications.  PNA’s Fire Retardant duct is chemically inert to most acids, aliphatic and aromatic organic compounds, chlorinated solvents, and alcohols.  Fire Retardant also has excellent mechanical properties over a wide range of temperatures as well as being abrasion resistant with a relatively low coefficient of friction.

Not UL Listed. Orange Only.

Fire retardant duct has been tested and is offered in the top class (UL94 V-O only). Because the process of making Fire-retardant duct eliminates UV protection, it must be installed safe from exposure to natural or any other UV light.

Sizes Available: 1″, 1-1/4″

PNA uses a PVDF copolymer specially developed for wire and cable applications, which are very demanding with respect to fire resistance and smoke emissions.
