Spiral pipe of this type is a core component in low-pressure supply and return air distribution systems, delivering rigid, leak-resistant round ductwork that holds shape under typical HVAC static pressures. The helical seam construction adds rigidity compared to longitudinal seam pipe, making it well-suited for long straight runs. Licensed HVAC technicians and sheet metal contractors are the primary installers of this product.\u003c\/p\u003e\u003cp\u003eThis spiral pipe is used in residential and light commercial forced-air HVAC systems where round duct is the preferred or specified distribution method. Common applications include main trunk extensions, branch runouts off rectangular plenums, and supply or return air risers in multi-story builds. At 18 inches in diameter it is typically found in larger residential systems or commercial fan coil and air handler applications requiring higher airflow capacity. Fabrication and installation must conform to ACCA and SMACNA standards as specified for this product.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHot dip galvanized steel construction resists corrosion in both conditioned and unconditioned spaces\u003c\/li\u003e\n\u003cli\u003e24 gauge material thickness provides structural rigidity for low-pressure HVAC ductwork applications\u003c\/li\u003e\n\u003cli\u003eSpiral seam fabrication increases pipe stiffness and reduces deflection on unsupported spans\u003c\/li\u003e\n\u003cli\u003e18-inch diameter accommodates high-volume airflow in larger residential or light commercial systems\u003c\/li\u003e\n\u003cli\u003e10-foot length minimizes the number of joints needed on straight duct runs, reducing leakage points\u003c\/li\u003e\n\u003cli\u003eMeets ACCA and SMACNA applicable standards for sheet metal duct construction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in ACCA- and SMACNA-compliant round duct systems.

Power down the air handling unit and verify the system is de-energized before connecting to any supply or return air section. Secure joints with approved drive cleats or slip connectors and seal all connections with UL 181-rated mastic or foil tape to minimize air leakage. Support hangers should be spaced per SMACNA guidelines for the pipe diameter and gauge.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Spiral Seam\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 10 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Dip Galvanized Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Thickness\u003c\/strong\u003e: 24 Gauge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: ACCA, SMACNA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SOUTHWARK METAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SP10-24GA_18IN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284110999858,"sku":"SP10-24GA_18IN","price":159.34,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278870.jpg?v=1781068787","url":"https:\/\/voomisupply.com\/products\/southwark-metal-sp10-24ga_18in-spiral-pipe-24ga-18-in-10-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
