The specialized team from Petroval in France will conduct diagnostics of heating furnaces using infrared cameras. They will provide immediate technical feedback based on their expertise in infrared diagnostics deployed worldwide. Infrared thermography is a non-destructive testing method that measures surface temperatures using infrared cameras, checking the temperatures of industrial equipment such as refineries and petrochemical plants. By adjusting the wavelength through filters, the temperature of the target object is accurately measured through the flame of the burner. The measurable temperature can reach up to 1500°C, with measurement tolerances of ±5°C for 450°C to 650°C and ±10°C for 700°C to 900°C. The goal of Petroval's infrared specialist team is to identify potential limits occurring within the furnace, such as combustion, tube limit temperatures, tube damage, and heat flux distribution, and to provide immediate technical feedback based on their expertise in infrared diagnostics deployed worldwide. *For more details, please contact us or download the catalog.*

The TST company's swing coupling ensures a straight flow path without obstructions, resulting in extremely low losses in flow and pressure. (1) No-Pressure Attachment and Detachment The nipple can be attached in a no-pressure state, making it easy for anyone to use. (2) Safety Lock When swung to a straight position, the safety lock engages, preventing the nipple from detaching even under unexpected external forces. (3) Residual Pressure Release By sliding the safety lock and rotating the nipple about 70 degrees back to the release position, the pressure on the nipple side is released, preventing the "whip effect." (4) Excellent Durability Even when attached to air tools, damage due to tool vibrations, as seen with general products, is almost nonexistent (proven in use for over 15 years at a major factory). *For more details, please contact us or download the catalog.

In the maintenance of heat exchanger tubes, I believe that the current methods involve driving in taper pins to seal leaking tubes or using 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 with a dedicated tool. It maintains pressure resistance up to about 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-treatments such as heat treatment, applications related to the use of fire, and inspections during the welding process. However, Pop-A-Plug can reduce this workload and does not use heat, so there is no 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.

When using cap welding for the closure method during pressure testing of pipes, tubes, and conduits, we recommend using this Grip Tight plug for closure. It can achieve closure up to high pressure simply by assembling the plug to the end of the tube/pipe. (Max pressure rating: 96MPa) ● This will significantly reduce labor (cost) efforts. There is no need for the series of tasks involved in cap welding, cutting, or beveling; after assembling the plug and conducting the test, you only need to remove the plug.
