Our company provides "cleaning (internal cleaning and washing of tanks)." Inside the tank, sludge accumulates due to rust, water, and impurities. This sludge can cause corrosion of the tank, leading to leakage accidents, clogging of strainers, and failures such as boiler ignition issues. To prevent such failures and protect the tank from deterioration, it is necessary to carry out "internal cleaning." 【Differences from Internal Cleaning】 ■ Work can be performed during operation ■ No need to remove residual oil ■ Cost is low *For more details, please refer to the PDF document or feel free to contact us.

"FRP lining" is one of the effective tank maintenance methods. Compared to tank replacement, it can be carried out at about one-third of the cost. The construction period is also short, taking approximately 10 days for one 10kL tank and about 16 days for four tanks. Additionally, it can be performed while the business is operating, allowing for the extension of the tank's lifespan without interrupting operations. 【Features】 ■ Excellent weather resistance and heat resistance ■ Capable of producing various shapes ■ Electrically insulating and has excellent radio wave permeability ■ Excellent thermal insulation ■ Lightweight and has outstanding strength *For more details, please refer to the PDF document or feel free to contact us.
