We will introduce examples of the use of LLFA products such as "LLFA Tape" and "LLFA Smooth." These include emergency repairs for leaks that occurred at the joints of gas piping, initial responses to sprinkler pressure leaks, and urgent repairs for water leaks from the threaded joints of outdoor air conditioning cooling pipes, among others. Additionally, they can be used for insulation and protection of electrical cables and connection terminals, as well as waterproofing work. [Case Overview] ■ Target: Gas companies, electrical companies, plumbing contractors ■ Content: Repairs for piping leaks and water leaks, insulation and protection of electrical cables and connection terminals, and waterproofing work. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce case studies of LLFA products utilized by electric utility companies. "LLFA Tape" and "LLFA Smooth" can complete insulation and protection of electric cables and connection terminals, as well as waterproofing, with minimal effort. In traditional methods, it is necessary to remove adhesives for regular insulation testing, but with LLFA products, you can cut away the treated area using just a single cutter without worrying about adhesive residue. 【Other Use Cases】 ■ Short-circuit and ground fault measures up to 69kV ■ Prevention and maintenance of pipe leaks, corrosion, and salt damage ■ Leakage of fire extinguishing liquid caused by aging deterioration of fire protection equipment piping and degradation of sealing materials in joint piping *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study of the use of LLFA products by a gas operator. At a hot spring inn in Japan, a leak occurred from the joint of a gas pipe rising from the ground. An emergency repair was completed using "LLFA Tape" and "LLFA Smooth" on the corroded joint. [Case Overview] ■ Tape Usage: 3500mm ■ Smooth Usage: 500mm ■ Work Time: 15 minutes *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study of LLFA products utilized by plumbing contractors. On a scorching summer day, water leakage occurred from the threaded joint of the large air conditioning outdoor cooling pipe on the building's rooftop due to aging deterioration. A local equipment contractor performed emergency repairs, restoring the indoor air conditioning in a short time. 【Case Summary】 ■ Tape usage: 3500mm ■ Smooth usage: 20g ■ Work time: 30 minutes *For more details, please refer to the PDF document or feel free to contact us.

The "LLFA Tape/LLFA Smooth" is a product well-suited for emergency response to pipe expansion and rupture caused by freezing during the harsh winter months. It can be installed quickly without the need for mechanical tools, making it especially useful during late-night or early-morning hours when expansion ruptures are most concentrated, without producing loud work noises. By using "LLFA Smooth" in conjunction, it is also possible to apply it to various uneven areas such as joints, step areas, and around reinforcements. 【Lineup】 ■ LLFA Tape (Red) ■ LLFA Smooth *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce a case study on the use of LLFA products for sprinklers. It is said that about 90% of sprinkler systems nationwide are wet sprinklers, which have water constantly filled in the pipes. There has been an increase in incidents of leaks caused by tiny pinholes due to corrosion from aging metal pipes and cracks at joint sections. The "LLFA Tape" can be wrapped around the leaking areas to effectively stop the leaks and prevent further damage. 【Case Overview】 ■ Target - Installation to address leaks from a pinhole with a diameter of 1mm in a straight section of a water pipe with an internal pressure of 3kg/cm² and a pipe diameter of 20A. ■ LLFA Tape Usage: Approximately 200mm *One roll can repair about 50 locations under the same conditions. *For more details, please refer to the PDF document or feel free to contact us.

If there is a water leak of about 1 MPa, it can be instantly stopped without closing the valve. It is also suitable for use underwater and can be buried. It can be used in a temperature range of -90°C to +260°C, making it compatible with various fluids such as high-temperature steam, air, gas (city gas and propane), and hydrogen sulfide. It can also be used for up to about 3 days as a temporary measure for acids, alkalis, lubricants, fuels, and other oils and fats. It is compatible with various piping materials, supporting use in diverse environments. There is no expiration date, so you can use it anytime without worrying about a validity period until it is completely used up. Additionally, it has over 20 years of weather resistance after application, making it suitable for permanent installations. By using the sister product LLFA Smooth (dedicated filling putty) to level out steps and gaps, it becomes easy to apply to joint steps, threaded areas, and uneven surfaces caused by corrosion. LLFA products have been widely adopted by nine major electric power companies in Japan, major automobile manufacturers, electrical manufacturers, local government water departments, and large food and beverage manufacturers. ■ For more details, please contact us.

LLFA Smooth is a supplementary filling putty specifically designed for the self-fusing tape LLFA Tape. It is used in conjunction with LLFA Tape when there are uneven surfaces at joint areas or when the surface of the installation is uneven due to corrosion. It can be torn and used like clay, allowing for the leveling of steps and gaps, making it easy to apply to joint steps, screw threads, and uneven areas caused by corrosion, thereby significantly expanding the range of application. This unique system, which uses putty in conjunction, effectively fills steps and gaps, providing higher sealing performance. *Note: LLFA Smooth alone cannot be used for insulation or leak repairs.*

LLFA tape is effective for insulation, waterproofing, and leak repairs in various cases. It is suitable for special high-voltage safety work from high pressure up to 69kV, and can last for 20 years after installation. It performs excellently over long periods in various environmental conditions, including outdoor UV exposure, high temperature and humidity, underwater, and corrosive piping. No specialized tools are required for installation, making it easy to use. It can be utilized for various repair and maintenance tasks at a low cost. It is also suitable for insulation treatment in large-scale power transformation facilities and for preventing animal damage that could lead to moisture, short circuits, or ground faults in cubicles. With a storage life of up to 40 years, it can be confidently introduced as a safety measure. Using the sister product LLFA Smooth (a dedicated filling putty), it is easy to level out steps, uneven surfaces, and gaps, facilitating the installation process. Its electrical and mechanical performance is equivalent to that of LLFA tape. LLFA products have been widely adopted by nine domestic power companies, major automobile manufacturers, electrical manufacturers, municipal water departments, and large food and beverage manufacturers.
