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.

The EST Group's G-160 tube tester can safely and quickly detect tube leaks by injecting air from a gun. Leak checks can be performed in just a few seconds per tube, improving time loss during equipment malfunctions. Each gun weighs less than 1 kg, and the neoprene seal and gripper design effectively enhance safety and reduce the burden on operators. There are also extension tools available, making it effective for air fins and other applications. Additionally, we offer the vacuum tester G-650, which can check for leaks at the junction of tube plates and tubes. *Please feel free to contact us if you would like detailed materials or explanations. (You can also easily request size selection or quotes.)*

In plant maintenance piping work, pressure tests of weld points, purging during welding, and upstream monitoring can be performed. - Local implementation with a plug is possible, eliminating the need for ancillary work. - Significant reduction in labor (cost) is achieved. - It can be used repeatedly multiple times. - Local testing allows for a reduction in the amount of medium used. Pressure tests can be conducted on various shapes of flanges, such as neck flanges and slip-on flanges. *For more details, please download the PDF or contact us.

Curtiss-Wright Corporation in the United States offers maintenance technologies with special features called "Pop-A-Plug" and "High Lift Flange Plug." 【Pop-A-Plug】 The Pop-A-Plug allows anyone to easily seal heat exchanger tubes in high-pressure equipment without the need for welding. - No welding required: Since welding is not necessary, there is no need for fire permits or inspections related to welding. - High-pressure compatible: It can withstand a maximum pressure of 48MPa and is used in various plant equipment. - No qualified personnel or skilled techniques required: With engineered plugs and specialized tools, anyone can achieve the same quality of crimp sealing. - Reduced labor: Significantly shortens work time and equipment recovery time. 【High Lift Flange Plug】 This is a tool for local pressure testing of flange welds, capable of testing up to high pressure. - Capable of testing up to high pressure: Flange #150 is 3.1MPa, #300 is 7.7MPa, and #600 is 15.5MPa. - Compatible with various flange shapes: WN, SO, SW. There are already numerous achievements, particularly in the maintenance sites of domestic petrochemical plants. *For more details, please feel free to contact us.
