US CW Company☆ Maintenance tools for piping and heat exchange tubes.
Curtiss Wright-EST Corporation / High Lift Flange Plug & Pop-Up Plug
☆Maintenance technology from CW Corporation, USA☆ High-pressure test flange local pressure resistance jig! No welding required, and high-pressure specification heat exchange tubes can be closed with a single touch!
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.
