Customers struggling with steam! Here is the solution!

Are you using PTFE or joint sheets and experiencing significant leakage with steam? Our expanded graphite gaskets improve the handling issues and are widely used in the market. Here are two of our gaskets: - 8851ND CleaLock The 8851ND CleaLock is our original gasket made from high-density expanded graphite combined with stainless steel. This improves handling and provides a good tightening feel, which has received great acclaim from operators. Additionally, we have a quick turnaround time, typically responding within 3-4 days, and we will do our best to accommodate urgent requests, so please feel free to contact us. - 1500 HOCHDRUCK-Pro The 1500 HOCHDRUCK-Pro retains the soft expanded graphite while featuring multiple layers of stainless steel. It has 5 layers of stainless steel at a thickness of 3mm and 7 layers at a thickness of 4mm. It can be used under high pressure, making it a popular choice as an emergency substitute for metal gaskets, and of course, we can also provide quick delivery.

The gasket during flange release suppresses the sticking of the packing, significantly reducing flange cleaning time!

The anti-seizing spray eCLEAR is a gasket anti-seizing spray based on inorganic minerals. Please apply it to the gasket before tightening. This will help suppress seizing during opening. <Features> - Prevents gasket burning (seizing) to flanges! - Compatible with most gasket materials! - Significantly reduces flange cleaning time! - Excellent heat resistance up to 800℃ - Can be used in conjunction with gasket seal paste (seal auxiliary agent)! *It cannot remove gaskets that have already seized. Please apply it beforehand. *The heat resistance temperature depends on the performance of the base material gasket.

[Free Sample Offered] Easy, convenient, and with excellent permeability, making the difficult task of removing bolts easy!

If you apply an appropriate amount to the bolt you want to loosen, it will penetrate in about 30 minutes. Applying it the day before will make it more effective in loosening. This is expected to shorten the time required for disassembly and inspection. 【Features】 ■ Improved equipment operating rate ■ Cost benefits from reusing bolts ■ Reduction in the number of bolts to be removed and associated costs *For more details, please download the PDF or feel free to contact us. *If you would like a free sample, please reach out to us through the contact form.

At construction sites, temporary parking lots may be established for workers and construction-related vehicles. On unpaved ground, mud and ruts can easily occur due to rain, which may hinder vehicle access. Hyper CLT mats are civil engineering materials that utilize wood CLT. By laying them in temporary parking lots, a suitable environment for vehicle passage and parking can be created while protecting the ground. They can be laid only in the necessary areas, and after the construction is completed, they can be removed and repurposed for temporary roads or access routes. The 5×10 panels weigh approximately 230 kg, and the 5×20 panels weigh about 460 kg, making them lightweight and easy to install and remove even with small machinery, allowing for changes in parking space. Additionally, they offer benefits unique to wood, such as glare reduction, noise reduction, and CO2 fixation. They are registered as a technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS as "TH-250021-A," and can be utilized for the development of temporary parking lots and innovative public works.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding repair methods can change the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Water Supply Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.
