One of the specialties of Nishiyama Manufacturing, known for thin-walled tubes, is the production of ultra-thin pipes. We can produce wall thicknesses down to (t = 0.2mm), making them suitable for lightweight components. By changing from solid to hollow, further weight reduction is possible, and by switching parts that are machined on the outer and inner surfaces to our pipes, significant reductions in processing time can be achieved. Additionally, special pipes often require large production lots, which may lead to cases where obtaining them becomes impossible. However, we can accommodate lots starting from 100 kg and can also handle very small lots, such as prototypes. 【Features】 ■ Expansion processing is possible ■ Flanges up to 1.7 times are possible ■ Pipes can be produced with strength tailored for bending processing ■ Manufacturing of ultra-thin-walled pipes is possible *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the products that utilize the "high-efficiency heat exchangers" handled by Nishiyama Manufacturing Co., Ltd. The system of the economical energy-saving device, "household natural refrigerant water heater (EcoCute)," includes "water heat exchangers" and "reheating heat exchangers." Our products are adopted in these heat exchangers, contributing to space-saving and energy efficiency. [Examples of high-efficiency heat exchanger products] ■ Household natural refrigerant water heater (EcoCute) - Tank unit → reheating heat exchanger - Heat pump unit → water heat exchanger *For more details, please refer to the PDF materials or feel free to contact us.

• Heat exchanger

The "high-efficiency heat exchanger" is a double heat exchanger developed to solve the shortcomings of conventional double-tube heat exchangers, using a newly developed "multi-leaf heat transfer tube." By making the inner tube of the double tube multi-leaf shaped, the contact (heat transfer) area with the fluid flowing on the outside is significantly increased without increasing the flow path cross-section. As a result, the heat exchange efficiency of the heat exchanger has been improved to more than twice that of conventional models. 【Features】 ■ Larger heat transfer area compared to round tubes, enabling miniaturization and weight reduction ■ Various cross-sectional shapes can be formed using the pull-out processing method (thin diameter and thin wall are also possible) ■ Both ends are round tubes, making connection for piping easy *For more details, please refer to the catalog or feel free to contact us.
