Quick branch plug "QLDER type" for drain discharge branch pipe.

You can create new air extraction points and connection routes without cutting the piping, saving time and costs.

The design prevents drainage that has accumulated at the bottom of the piping from mixing in easily. Additionally, by changing the installation direction of the quick branch plug, horizontal expansion and drainage discharge are also possible. There is no need to remove it, and post-installation work can be done easily.

20A heat-resistant plug and socket

It is resistant to oxidation, uses high-quality porcelain as the main insulating material, can withstand high temperatures, and has excellent insulation resistance.

Until now, commercially available plugs for electric heating devices have had several drawbacks, including low allowable current, inability to withstand high temperatures in areas close to the heat source, susceptibility to moisture leading to rust, and lack of electrical, thermal, and mechanical stability. Therefore, our company has been urgently developing a new product that addresses all these issues. After several years of monitoring, we have recently completed a heat-resistant plug rated at 20A, which has been approved under model number 41-26620 and is now available for sale. We particularly recommend the excellent 20A heat-resistant plug from Toyo Electric Heating.

Pop-A-Plug (Closure plug for heat exchanger tubes)

This is a mechanical plug for closing off heat exchange tubes. It is a groundbreaking maintenance method that eliminates the need for welding closures in high-pressure equipment.

In the maintenance of heat exchanger tubes, the current methods for sealing leaking tubes include driving in taper pins and seal welding for high-pressure equipment. The Pop-A-Plug from Curtis Wright in the United States uses a specially machined mechanical structure plug that is sealed using a dedicated tool. It maintains pressure resistance up to approximately 40 MPa, and seal welding after plugging is not required (the maximum pressure resistance varies by size). Welding work requires time for the work itself, pre-treatment such as heat treatment, applications related to the use of open flames, and inspections during the welding process. However, Pop-A-Plug can reduce this workload and does not use heat, thus preventing damage to the equipment. It is a sealing method that can significantly shorten the recovery period of the equipment. *According to ASME PCC-2-2022, the guidelines for the maintenance of pressure equipment, Pop-A-Plug is recommended as a tube plug for heat exchangers. *For more details, please download the PDF or contact us.
