Underground Pvc Hvac Ductwork

Underground duct systems shall be constructed of approved concrete clay metal or plastic.

Underground pvc hvac ductwork.

Pvs ductwork needs no protection in the earth from sand concrete or plaster. The maximum duct temperature for plastic ducts shall not be greater than 150 f 66 c. The blueduct is the only proven direct burial underground duct system made from ultra durable advanced hdpe high density polyethylene. Pvc duct pipe has excellent chemical resistance to most fumes gases and media.

Both pvc and hdpe are acceptable materials for temperatures up to 150e f. Joints are joined with either pvc or approved metal duct couplings. The sizes range from 2 up to 60 in diameter. Is an industry leader manufacturing pvs underground hvac ductwork.

The duct is available in sizes ranging from 4 inches through 24 inches. The blueduct products are engineered to protect against corrosion mold and mildew radon rust and air leaks. Ultimately you could save money with pvc ductwork. Standard pvc cement and primer can be used for installation.

This would be required for any underground plastic duct system. Durability pvs ductwork is a rugged durable material that will take ordinary shipping and handling without damage. Over time metal ductwork can rust and will need to be replaced. In homes pvc ductwork can allow a heating and cooling system to run beneath the house without being corroded by moisture or even radon.

Spiral manufacturing co inc. Most commonly used in industrial hvac applications for new constructions. Also known as pvs or pcd polyvinyl coated steel duct and fittings. The smooth interior of the plastic duct has minimal friction resistance to air flow.

Pvs ductwork is specified by more engineers and architects than any other underground hvac duct system. Pvc duct pipe is rated to handle temperatures up to 140 degrees f. In addition to providing the industry with sheetmetal fittings our coated duct is compatible with hundreds of chemicals for exhaust and make up air systems. Underground duct pvs polyvinyl steel coated underground hvac duct also known as pcd pvc coated and pvcs is ul listed and specified more often by architects engineers and contractors than any other underground air delivery system because it offers both the strength of steel and the inertness of plastic.

The blueduct underground duct for hvac is the only proven direct burial underground duct system made from ultra durable advanced hdpe high density polyethylene. Metal ducts shall be protected from corrosion in an approved manner or shall be completely encased in concrete not less than 2 inches 51 mm thick.
