This is an optimal piping support fitting for various pipes with insulation. It eliminates the welding process entirely and is constructed using a bending and fitting assembly method, achieving cost reduction. In the construction site, welding with the pipes is completely unnecessary. Benefits of being weld-free: - No need for skilled craftsmanship (welders) - Elimination of thermal distortion and finishing work - No need for compliance with regulations (welding fumes), etc. By eliminating deformation and thermal effects caused by welding, it contributes to stabilizing quality, shortening manufacturing lead times, maintaining high quality, and reducing costs. It can be used for pipe diameters from 15A to 400A and at pipe temperatures below 593°C. *For more details, please refer to the PDF document (product dimensional specifications).

In industrial plants, piping plays a crucial role in connecting various equipment and devices that make up the plant, and the function of pipe supports (also referred to as hangers) is to install and maintain these pipes within the plant's space. If this role is not fulfilled safely and reliably, it can cause undue forces and stresses on the piping, adversely affecting the connected equipment and potentially disrupting the operation of the plant. Therefore, to maintain and operate the plant safely, regular inspection and maintenance of pipe supports are essential, and planned periodic inspections and diagnostics are necessary. From the perspective of diagnosing pipe supports, we will explain in detail the diagnostic methods, their effects, and examples of non-conforming items detected through inspections. Please feel free to download the PDF document (Technical Material: Inspection and Diagnostic Techniques for Pipe Supports) or contact us for more information. According to your needs, we will conduct on-site inspections and diagnostics of pipe supports by experienced technicians.

This is a support bracket suitable for a wide range of pipe diameters and high-temperature piping. Specifically, it is a newly developed weldless pipe shoe saddle designed for use as a slide support in areas where the axial load on the piping is relatively large. In the manufacturing process, welding has been thoroughly eliminated, and the main components are constructed using a press machine for plate bending and assembly through fitting, thus eliminating deformation and thermal effects caused by welding, achieving quality stabilization and low cost. No welding is required at the construction site. By omitting the burdens associated with the welding process (such as heat treatment and securing skilled workers), it contributes to a reduction in construction days, maintenance of high quality, and cost reduction in piping construction, where these burdens can significantly increase costs. It is ideal for slide supports for high-temperature piping with insulation, such as in power plants. It can be used for pipe diameters from 65A to 400A and for pipe temperatures up to 593°C.

As environmental awareness increases and it becomes clear that severe noise can harm health, effective measures are being sought. In places where traditional heavy and rigid concrete systems cannot be used, the lightweight and flexible CISILENT soundproof wall demonstrates excellent effectiveness. Even in cases with spatial and technical issues, weight restrictions, and other constraints, new possibilities open up both indoors and outdoors. CISILENT efficiently solves noise problems. It features a lightweight structure that can be installed in narrow spaces and is easy to transport. Its simple assembly allows it to be used as a temporary system. The transmission loss of the flexible soundproof wall CISILENT is Rw=25dB, meeting the requirements of the German guidelines for road noise barriers (ZTW-Lsw 88). Moreover, when comparing the weight per unit area, it is significantly lighter than traditional sound barriers. Even if bulk materials have the same mass per unit area as CISILENT, their sound insulation effect is inferior. This is because their high rigidity causes sound to hit the surface and diffuse again. In contrast, the flexible CISILENT exhibits sound insulation effects proportional to its mass.

<Spring-type Vibration Isolation Device> Effectively isolates vibrations from structures and machinery using spring components. <Viscoelastic Damper> Viscoelastic dampers reduce vibrations during operation with high damping force. This device allows displacement in all directions of connected equipment while reducing vibrations at any position. It can be applied in all industrial fields, including structures and large machinery, with a simple installation method and high efficiency, but is particularly suitable for areas where displacement needs to be considered, such as complex piping systems. <Tuned Mass Damper (TMD)> Tuned Mass Dampers (TMD) are effective when there is insufficient space for the installation of conventional dampers. TMDs are devices that incorporate mass, springs, and damping mechanisms, functioning by being directly attached to vibrating structures or piping systems. To achieve sufficient effectiveness, TMDs need to be tuned to the natural frequency of the object being protected.
