It holds an inert purge gas — typically argon or nitrogen — directly at the weld area to prevent oxidation and maintain weld quality on stainless steel, titanium, and other oxidation-sensitive alloys. Sized for 36-inch diameter pipe, each dam ships with tape pre-installed in sections for precise alignment inside the pipe bore. The water-soluble paper construction dissolves rapidly after welding, leaving no residue in the line and eliminating the need for manual retrieval.\u003c\/p\u003e\n\u003cp\u003eThis purge dam is used in industrial piping, process piping, and structural fabrication where back-purge gas coverage is required to meet weld quality standards. It is suited for shop fabrication and field welding on large-diameter pipe runs. Side walls are tapered to fit different pipe schedules, so the same dam works across varying wall thicknesses at the 36-inch nominal diameter. The package contains 24 dams, supporting production welding environments and reducing per-joint material cost on high-volume jobs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSized for 36-inch compatible pipe diameter\u003c\/li\u003e\n  \u003cli\u003eWater-soluble paper dissolves rapidly and leaves no residue after weld completion\u003c\/li\u003e\n  \u003cli\u003eTape pre-installed in sections for precise, repeatable alignment inside the pipe\u003c\/li\u003e\n  \u003cli\u003eTapered side walls accommodate different pipe schedules at the same nominal diameter\u003c\/li\u003e\n  \u003cli\u003ePositions 12 inches from the weld centerline for effective gas isolation\u003c\/li\u003e\n  \u003cli\u003eEPA approved water-soluble material — compliant with environmental discharge requirements\u003c\/li\u003e\n  \u003cli\u003ePack of 24 dams for production and high-volume welding applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 36-inch diameter pipe across varying pipe schedules.

Before installation, confirm the pipe interior is clean and dry to ensure proper adhesion of the pre-installed tape sections. Insert the dam at the specified distance from the weld joint — 12 inches as indicated — and verify a consistent seal around the pipe wall before introducing purge gas. After welding is complete, the dam dissolves on contact with water; flush the line per standard post-weld procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Pipe Diameter\u003c\/strong\u003e: 36 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDistance from Weld\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Water-soluble paper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWater Soluble\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: EPA Approved\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: United States\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: AQUASOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ezp-36\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AQUASOL","offers":[{"title":"Default Title","offer_id":51268829610290,"sku":"EZP-36","price":339.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308911920.jpg?v=1780706909","url":"https:\/\/voomisupply.com\/products\/aquasol-ezp-36-pre-formed-purge-dam-36-in-dia-pk24","provider":"Voomi Supply","version":"1.0","type":"link"}
