New Function Inducing Joint ID

New Function Inducing Joint ID

It will reliably contribute to crack prevention in concrete structures.

Concrete structures are subject to deformation due to factors such as hydration heat during setting and hardening, temperature changes caused by external air temperature, drying shrinkage, and external forces. When such deformations are restrained, cracks occur. The corrosion of reinforcing steel due to decreased water tightness from these cracks is expected to become a significant issue for the durability of concrete structures in the future. To improve waterproofing and prevent corrosion of reinforcing steel, we have developed a new functional inducing joint material called ID Joint.

Philosophy and Theory in Design: "Hulls" Edition

Philosophy and Theory in Design: "Hulls" Edition

The load is distributed across the entire joint area! The strength lasts for 10 to 20 years of use.

We would like to introduce the philosophy and theory behind the design of the "hull" of our company's boats. Through various tests, including those conducted at industrial testing facilities, we have demonstrated that our hulls possess the strength to withstand pulling tests exceeding 3 tons. By using the same FRP material as the hull throughout the entire joint cross-section and significantly reinforcing the joint areas compared to the average strength of the hull itself, we achieve overwhelming strength and durability. The hull section that supports the floats incorporates structures and theories that were being researched and developed at the time for aircraft and racing cars, which are applied to the hull reinforcement areas. 【Features】 ■ The boat body is produced in-house with a consistent process. ■ A thorough commitment to using world-class materials. ■ A special reinforcement structure theory for the hull area where the floats are attached. ■ Designed to ensure the entire bottom of the boat is flat. ■ The bow section is rounded, adopting a wide-bottomed hull structure. *For more details, please refer to the PDF materials or feel free to contact us.

Formless framework construction products

Formless framework construction products

It is a pit formation method that does not require formwork construction or rebar welding work.

This is a new construction method that simplifies the formation of indoor floor drainage channels and wiring/piping pits, enabling significant reductions in construction time. There is no need for formwork construction when forming drainage channels or welding during the installation of receiving frames. Level adjustment of the receiving frames is also easy, achieving a reduction in construction time compared to conventional methods. Additionally, there is no waste from formwork, contributing to a reduction in environmental impact. *For more details, please download the PDF or contact us.*

Transparent Joint "SPC Joint"

Transparent Joint "SPC Joint"

A joint that shapes the bonding surface using its unique molding technology without the use of any abrasives.

The connection part of the SPC joint is colorless and transparent, allowing for a clear view of the interior. It has excellent visibility for thermometer scales and other markings. General fitting joints, including transparent joints, are finished on both contact surfaces by using sand as an abrasive to eliminate large irregularities. The SPC joint is formed without any abrasives, using Shibata Science's unique molding technology, which shapes the joining surfaces. Therefore, it has excellent airtightness due to superior surface processing. The SPC joint is molded without scratching the original smooth glass surface with sand, making it a high-smooth surface joint that stands apart from fitting joints that include transparent joints. 【Features】 ○ The joint part is colorless and transparent ○ No grease is required For more details, please contact us or download the catalog.

Swivel joint

Swivel joint

Swivel joints are ideal for hose vibrations and twisting! They can be used in the piping of machines that use mineral-based hydraulic oil as the fluid!

The connection position of the high-pressure hose can be oriented in any direction, allowing for shorter piping and reduced installation time. It is prepared to match the specifications of the high-pressure hose fittings. The swivel joint can easily rotate 360 degrees even when pressurized. There are two types of operating pressure: 21MPa (210kgf/cm²) and 35MPa (350kgf/cm²).

[Case Study] Contributing to Cost Reduction and Environmental Conservation through Efficiency in Steam Management

[Case Study] Contributing to Cost Reduction and Environmental Conservation through Efficiency in Steam Management

Improve efficiency through steam management, contributing to cost reduction and environmental conservation!

At the paper manufacturing company, in the dry part of the paper machine (the machine used to produce paper), there was a high usage of steam, leading to increased costs, and frequent maintenance was causing issues in terms of time, effort, and expenses. Issues: 1. The amount of steam supplied to the cylinder dryers is excessive. 2. To increase production, there is a desire to increase machine speed. 3. The wear of the seal rings (carbon) in the rotary joints currently in use is rapid, resulting in significant losses due to steam leaks, and maintenance requires a considerable amount of time and effort. 4. There are temperature inconsistencies on the surface of the cylinder dryers, leading to poor product yield. In the process of manufacturing thick paper at the paper mill, a large amount of steam is introduced into several large cylinder dryers (approximately φ2000) to heat the surface and facilitate drying.

[Examples Related to Labor Saving] Screw Joint for the Water Heater Industry

[Examples Related to Labor Saving] Screw Joint for the Water Heater Industry

Streamlining water tests, solving challenges with a one-touch screw joint!

We received an inquiry from a customer who manufactures water heaters, seeking to improve the efficiency of their inspection process, which includes checking for cracks in the piping and leaks from welds through water flow tests before shipment. We proposed a specially designed "male joint" tailored to their work. As a result, the time required for inspections has been significantly reduced. The number of inspections that can be conducted per day has increased from 80 to 240, tripling the capacity. [Case Study] ■ Issues - Time-consuming installation and removal - Past incidents of seal tape remnants entering the piping ■ Proposal - We proposed a specially designed male joint tailored to their work. *For more details, please refer to the PDF document or feel free to contact us.
