This document describes the case of installing oil tanks in the limited space of existing office buildings, focusing mainly on the "installation of vertical oil tanks" and the "adoption of flexible piping for underground installation." In this instance, we demonstrated a case of applying vertical oil tanks and UPP piping in the renewal construction, suitable for installation in confined spaces. As the demand for BCP power supply measures is expected to continue to rise, we hope this article will serve as a reference for future construction projects. 【Contents】 ■ Introduction ■ Overview of the construction and constraints ■ Installation of vertical oil tanks in confined spaces ■ Background of adopting flexible piping for underground installation ■ Conclusion *For more details, please refer to the PDF document or feel free to contact us.

The "UPP Double Pipe" is a flexible piping made of high-density polyethylene resin, which incorporates a primary pipe with a liner and a protective pipe pre-assembled. It can be cut to the desired length, and generally does not require pipe connections in the buried section. It adopts "electrofusion joining" without fittings, which minimizes the risk of leakage during connection. It is resistant to corrosion and galvanic corrosion, ensuring high pressure resistance even when buried, and exhibits excellent resistance to the absorption and permeation of gasoline and alcohol-blended fuels. Installation of a leakage detection system is also possible. Piping can be buried underground directly without a trench, significantly contributing to the reduction of construction time and costs for fuel piping installation. ★ You can view a PDF comparison document that clearly shows the benefits! 【Features】 ■ Allows for underground piping installation without a trench ■ Significantly reduces installation labor and costs ■ Offers pipes up to 100 meters in length ■ Supports continuous monitoring with a leakage detection system ◎ Kajima Corporation will present on this product at the National Conference of the Electrical Equipment Society! * For details, please refer to the PDF or feel free to contact us. * We also handle "corrugated type stainless steel piping," which is characterized by high safety.

At P&D Japan, we handle "corrugated stainless steel piping" characterized by high safety. 1. Single piping - The temperature of the hot water passing through the piping (above 40 degrees) is transmitted through thermal conduction → fermentation progresses. - The piping is spiral-shaped → it has a larger surface area and transmits heat easily. - Despite being made of steel, it is flexible. ⇒ In addition to contributing to the progress of fermentation, it is suitable for fermentation tanks and is utilized in "effective heating systems for biogas fermentation tanks." (Case studies are summarized in the PDF. Please download it.) 2. Double piping - Complies with the Water Pollution Control Act for the transport of toxic liquids and gases, such as harmful chemicals. - Can be delivered in the required lengths, eliminating the need for fittings. - Utilizes the gap between the primary and secondary pipes for leak detection and prevention. - High-spec design that can be utilized in facilities where operational downtime due to external factors must be absolutely avoided. ⇒ Used in data centers and other applications. ■ Adoption results Teijin DuPont Film Co., Ltd., NEXCO, and others. *For more details, please download the PDF.

The "Leak Prevention (Detection) System" is a system that enables early prevention of leaks by sounding an alarm in the event of an abnormality (leak) in the piping. Air or nitrogen is pressurized and filled between the primary and secondary pipes (sleeve pipes), and the leak prevention (detection) device detects the level of pressure drop (whether it is a natural decrease or an abnormal occurrence). 【Features】 ■ Continuous monitoring can be performed, allowing for safe facility operation. ■ Leak prevention (detection) is also possible for double-shell tanks (underground tanks) and aboveground tanks. ■ Available in pressure type and vacuum type. ■ Depending on the installation situation, the best system can be proposed from various types. *For more details, please refer to the catalog or feel free to contact us.

The "UPP System Piping" offers a variety of underground fuel pipes that can be used for different types of fuels. The primary pipe (with liner) has a single-layer structure made of high-density polyethylene (PE100) and features an EVOH lining on the inside. The secondary pipe is also made of high-density polyethylene (PE100) with a single-layer structure, but without EVOH lining, and is used as a protective pipe for the primary pipe. The double pipe is a system where the primary pipe with a liner and the protective pipe are pre-assembled, designed to be cut to the required length, thus eliminating the need for pipe connections in the buried section. 【Features】 ■ High resistance to damage (strong seismic resistance) ■ No leakage due to electric fusion connections of joints ■ No corrosion due to the material being resin (high-density polyethylene) ■ Product lifespan of 50 years (manufacturer's warranty of 30 years) ■ Easy installation reduces construction costs compared to existing works (steel pipes) *For more details, please refer to the catalog or feel free to contact us.
