ジャパン・エンヂニアリング株式会社 List of Products and Services

Japan Engineering's "Smile Joint" is a new fitting that achieves "housing joints" with high-performance polyethylene pipes that excel in corrosion resistance and seismic resistance. Due to factory prefabrication, on-site fusion processing is not required. Additionally, since no fusion machine is used, it can be installed without being affected by site conditions such as high floors, narrow spaces, power shortages, or exposure to rain. 【Features】 ■ Uses cast iron ring type housing ■ No on-site fusion processing required ■ Stable quality through factory prefabrication ■ Easy installation with two bolts ■ Obtained technical review certification from the General Incorporated Foundation Better Living *For more details, please refer to the PDF materials or feel free to contact us.

Japan Engineering's "Stainless Steel Sprinkler Piping" significantly improves construction efficiency by changing from the traditional carbon steel pipe (SGP) threaded joint method to a housing joint connection method using general-purpose stainless steel pipes (Su). It can reduce the overall construction cost by 5% to 10%. We also propose considering piping loops and calculating friction losses. **Benefits of Switching to Stainless Steel Piping** - No waste generated on-site due to factory processing, and no additional space required. - Easy installation with just two bolts, making it possible for unskilled workers to install. - Improved durability. - Size reduction of the diameter is possible due to differences in flow coefficient. *For more details, please refer to the PDF document or feel free to contact us.*

Japan Engineering's "High-Performance Polyethylene Pipe" is a polyethylene piping that excels in corrosion resistance and seismic resistance, with no concerns about condensation. Since the piping is fused in the factory, the pipes delivered to the site are simple to assemble, leading to cost reductions. There are two types of piping processing methods: butt fusion and EF coupling, allowing for various pipe types to be proposed according to applications and environments. 【Features】 ■ No skilled labor required, enabling shorter construction periods ■ Significant reduction in fusion points on site ■ Easy installation ■ No need for disposal of leftover materials on site ■ Butt fusion can cut material costs by approximately 25% *For more details, please refer to the PDF document or feel free to contact us.

Japan Engineering's "Stainless Steel Firefighting Equipment Piping" utilizes stainless steel pipes for general piping, achieving longer lifespan and reduced weight, while improving workability and safety in firefighting equipment piping. This product can be used as a substitute for the carbon steel pipes used in conventional delivery pipes for S/40 pressure piping, eliminating deterioration due to rust and providing a lighter option. Due to the difference in flow coefficient, it is possible to reduce the pipe diameter, which can lower material and labor costs. 【Features】 ■ Possibility of reducing pipe diameter ■ Improved durability, extended lifespan, and reduced aging deterioration ■ Enhanced workability and safety through significant weight reduction ■ Firefighting certification obtained *For more details, please refer to the PDF document or feel free to contact us.

Japan Engineering's "In-Pipe Phoenix" is a method that creates new pipes inside existing piping, allowing for the reuse of the piping. Compared to replacement construction, it features less noise and dust, and it can be performed even when pipes are embedded in walls. It can also regenerate pipes with holes, and the drainage restrictions are typically just one day, resulting in a short construction period, making it an environmentally friendly method for residents. 【Features】 ■ New pipes are created inside existing pipes, revitalizing the piping ■ Construction is possible even when pipes are embedded in walls ■ Epoxy resin and PVC shape memory resin are used according to the application ■ Less noise and dust, with a short construction period ■ Warranty ranges from 10 years *For more details, please refer to the catalog or feel free to contact us.

"SUS Mate" is a suitable piping material for sites where water must be passed through immediately, like during renovation work. In response to the voices from the field asking for "products that can be delivered faster and are easier to install than processed pipes," we made it a reality. We keep standard fittings with grooves (notched) processed on both ends and J-housings in stock at the factory, and if you place your order by 14:00 on weekdays, we will ship it on the same day. [Features] - Made of stainless steel, ensuring hygiene - Approximately one-third the weight of carbon steel pipes and PVC-lined steel pipes - Uses standard stock fittings, with straight pipes processed and installed on-site - Easy installation with housings, and maintenance is also simple - Fully recyclable *For more details, please refer to the PDF materials or feel free to contact us.
