CURTISS-WRIGHT Corporation Pop-A-Plug
★New Method for Closing Heat Exchange Tubes by CW Company, USA★ This is a groundbreaking technology that allows for closure with a one-touch, no welding required. There are many successful cases in domestic plants!
The "Pop-A-Plug" from Curtis Wright in the United States is a completely new method for plugging heat exchanger tubes that does not require welding. It uses a special tool to crimp a uniquely designed plug. After polishing with a dedicated brush, a one-touch crimp closure is completed with the same material plug. It has already been adopted in numerous maintenance projects for domestic oil refining, petrochemical, and chemical plants. 【Features and Benefits】 ■ Significant reduction in labor hours is possible. ■ No need for fire permits or welding inspections, and no welding damage, as it does not use open flame welding. ■ Recommended by ASME standards for maintenance guidelines. ■ Permanent closure is possible with equivalent material plugs for each tube. ■ Maximum pressure resistance: 48MPa. ■ Applicable tube inner diameter: minimum 12.00mm to maximum 52.50mm. *For more details, please download the PDF or contact us.
