Flexible Joint for Refrigerant Copper Pipes "Reflex"

Flexible Joint for Refrigerant Copper Pipes "Reflex"

Attention facility managers of school air conditioning systems. The "Reflex," compliant with the Ministry of Land, Infrastructure, Transport and Tourism's piping guidelines, is being increasingly adopted in public schools!

The installation of air conditioning systems in public elementary and junior high schools has become an urgent issue, and the government has announced the installation of air conditioning systems in all (public) elementary and junior high schools. The costs have been included in the government budget. Due to the low height and long horizontal layout of school buildings, expansion joints are often installed. This is because dividing the structure can minimize the damage the building receives from external forces such as earthquakes. The piping guidelines in the Ministry of Land, Infrastructure, Transport and Tourism's "Standard Specifications for Public Building Construction" mandate the use of flexible joints for piping that passes through expansion joints. As a result, the demand for Reflex, which complies with these piping guidelines and ensures the proper use of joints, has surged, and it is being increasingly adopted in public schools. [Please see our delivery records.] Additionally, Reflex is typically in stock, allowing for quick responses to urgent construction needs. *For more details about the product, please refer to the PDF materials or feel free to contact us.

★New Product★【Affordable and Easy Installation!】Ideal for Connecting Drain Pipes

★New Product★【Affordable and Easy Installation!】Ideal for Connecting Drain Pipes

This is a drainage joint for exposed piping. It is easy to install with band tightening! The inner surface is flat.

This product is the exposed band clamp type of the Atom Joint (rubber flexible expansion joint/vibration joint) series, model 【AJ-DA】. Unlike metal flexible expansion joints, rubber flexible expansion joints are elastic materials themselves, allowing them to follow complex displacements, making them suitable for sites requiring eccentricity. The flat inner surface reduces the risk of liquid accumulation. 【Features】 ■ Easy installation with band clamping ■ Flat inner surface suitable for rainwater drainage ■ For exposed use *For more details, please refer to the PDF materials or feel free to contact us.

Bridge expansion device: Aluminum alloy cast joint: KMA joint

Bridge expansion device: Aluminum alloy cast joint: KMA joint

~Excellent durability and high performance requirements~

The expansion joints of road bridges have been treated as secondary components in design, despite being subjected to harsh conditions where they directly receive repeated vehicle loads. Additionally, the mechanism for transmitting forces to the expansion joints has not been clearly defined, and fatigue strength checks have hardly been conducted. Our company has conducted fatigue tests to confirm durability and developed the "KMA Joint," which meets the required performance of expansion joints: "stability during operation," "static and dynamic durability," "ensuring movement," "water-tightness," and "low noise and low vibration." To reduce the time required for replacing expansion joints, we have improved the anchoring structure that fixes the expansion joints to the deck slab by introducing prestress into the steel rods of our Sepec Joint, using a perforated jib for the anchoring structure.

Flexible expansion joint CL-A type

Flexible expansion joint CL-A type

The CL type closure joint is a flexible expansion joint developed with extensive experience and technology based on many years of proven performance.

Due to the effects of ground subsidence, earthquakes, temperature expansion and contraction, various stresses are applied to the piping, which can lead to leaks and pipe disconnections. Closure joints are most suitable for relieving such stresses and absorbing displacements. Because the structural reaction force is small, the impact on the piping and structures is extremely minimal. With long-lasting stable airtightness and excellent performance in absorbing large expansions, eccentricities, and twists, they are widely used, particularly in the fields of water supply, electricity, and plants. ● Absorption of displacements after piping - Uneven subsidence - Deflection - Bending - Twisting - Temperature expansion and contraction - Piping vibrations
