Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang AQUASOL dari 3G Electric.
What is the typical dissolution time for AQUASOL water-soluble purge dams after welding?
AQUASOL water-soluble purge dams are designed to dissolve when exposed to water or high humidity after welding. The dissolution time depends on water temperature, flow rate, and the thickness of the dam material. For standard pre-formed dams like the EZP-3, complete dissolution typically occurs within 30 minutes to 2 hours when flushed with warm water at 40-60°C. Cold water may extend the time. The dams leave no solid residue, eliminating the need for mechanical removal from the pipe.
Can AQUASOL fiberglass weld-backing tapes be used for multiple weld passes?
AQUASOL fiberglass backing tapes, such as the AFBT-4.0-200 and AFBT-2.5-200, are rated for a maximum continuous current of 200 A. They are intended for single-use applications, typically for root-pass or tack welding. The tape provides a backing surface that prevents burn-through and contains the weld puddle. After use, the tape is consumed or damaged and should be replaced for subsequent passes. For multi-pass welds, the tape is used only for the initial root pass.
What is the maximum pipe diameter that AQUASOL inflatable purge bladders can seal?
The AQUASOL inflatable purge bladder model ABLD-10 is designed for a maximum pipe diameter of 10 inches. It features a 12-inch harness length to secure the bladder in place. The bladder is inflated to create a seal inside the pipe, allowing for localized inert gas purging. For pipes larger than 10 inches, alternative sealing methods or larger bladder models may be required. Always verify the bladder size against the pipe inner diameter before use.
Are AQUASOL water-soluble purge papers suitable for use in vertical pipe welds?
Yes, AQUASOL water-soluble purge papers, available in sheets and rolls, can be used in vertical pipe welds. The paper is cut or positioned to form a dam inside the pipe. For vertical applications, the paper must be secured with adhesive or mechanical means to prevent displacement during welding. The paper dissolves after welding when exposed to water, leaving no residue. Thickness options include 0.089 mm (ASW-35/S-14RW) and 0.178 mm (ASW-60/R-15 and ASW-60/R-31), with thicker paper providing greater rigidity.
What is the adhesive-free width on AQUASOL aluminum tape, and why is it important?
The AQUASOL aluminum tape model EZ-ZT 2.5 has a total width of 2.5 inches, with a 1-inch adhesive-free width along one edge. This adhesive-free zone allows the tape to be positioned without sticking to the pipe surface, enabling precise placement for sealing purge areas or masking. The remaining 1.5 inches have adhesive for secure attachment. This design is useful for applications where the tape must bridge a gap or cover a joint without adhesive contamination in the weld zone.
