Piping routes tailored to the installation location for IR method/BCF method.

Piping routes tailored to the installation location for IR method/BCF method.

Custom piping routes tailored to the installation location are possible! We measure precise adhesive curing times to maintain quality.

Our company's "connecting" technology involves piping using pipe materials through welding or adhesive bonding to create fluid pathways. In addition to standard socket welding, we also offer the "IR method," which allows for non-contact construction using infrared, and the "BCF method," which enables construction without creating irregularities on the inner surface of the pathway. Furthermore, we can create original piping routes tailored to the installation location. Our space-saving design has reduced the burden on existing exclusion devices. 【Our connecting products (partial list)】 ■ Chemical relay box housing ■ PVC bending tank ■ PVC welded duct ■ PVDF utility piping ■ PVDF prefabricated piping *For more details, please download the PDF or feel free to contact us.

Duct series that is resistant to air leakage

Duct series that is resistant to air leakage

The leakage airflow is almost "zero" for the positive pressure duct "Non-Leak Duct." For negative pressure duct used in high-pressure ventilation systems such as long-distance shields, "Pita Joint Duct."

■ Non-Leak Duct (Positive Pressure Use) ● Non-Leak Duct (Packing Type) (Patent Application No. 2015-38261) Measured value φ2500 at 8kPa with a maximum leakage rate of 0.1m³/min (per one fastening connection point) Available in φ800 to φ2500, standard length of 10m ● Small Diameter Non-Leak Duct (Patent No. 4917069) This is a duct for positive pressure use. Air leakage is almost zero. With a leakage rate of 1/3700 compared to conventional ducts, it is an excellent air duct for long-distance small cross-section shield and tunnel ventilation. Available in φ300 to φ700, standard length of 10m ■ Pita Joint Duct (Negative Pressure Use) This is a duct for negative pressure use. Air leakage is almost zero even at -80kPa. With low friction resistance and good long-distance air delivery characteristics, it enables significant energy savings and allows for a smaller blower size. Compared to conventional steel pipes, the outer diameter of the joint section is smaller, allowing for space-saving installation. It offers excellent cost performance for methane gas exhaust, long-distance shields, small cross-section tunnel mechanical excavation, TBM, and more.

Bus duct construction examples

Bus duct construction examples

Introducing examples of construction such as a new concept bus duct that allows branching from the connection section!

A bus duct is a device that consists of a strip conductor made of copper or aluminum, covered with an insulating material or supported by an insulating material, and housed in a box-like case made of iron or aluminum. Our company's bus ducts are manufactured under strict quality control within a consistent production facility. In the installation of bus ducts, the correct tightening of connection bolts is the most important point. Kyodo Kaitech has achieved "non-loosening," "maintenance-free," and "visualization of safety" with its unique technology. ● You can view installation examples by downloading the catalog. If you have any questions, please feel free to contact us.

New factory "Ayase Plant" begins production.

New factory "Ayase Plant" begins production.

Manufacturing capacity is approximately 1.5 times greater! By having multiple manufacturing bases, we achieve BCP (Business Continuity Plan) response and stable supply.

Kyoudo Kaitech Co., Ltd. began construction of the new factory "Ayase Plant" on July 1, 2019, and started production on July 1, 2020. The construction of the "Ayase Plant" aims to address BCP (Business Continuity Planning) and the increasing demand for bus ducts. We will enhance productivity by establishing a continuous manufacturing line that only allows horizontal movement, which was impossible at the current Kanagawa Technical Center, and by semi-automating the sheet metal processing that is currently done manually. Our company offers a wide range of bus duct products, including the "E-BD type insulated bus duct" and the "F-PE type fire-resistant bus duct." We also handle the SS-T type low-pressure trunk line system "Shaft Star," which has been developed specifically for medium-sized buildings such as tenant buildings and apartments, as well as logistics warehouses. *For more details, please refer to the PDF document or feel free to contact us.
