S-joint brass product "Ring Sleeve Joint"

S-joint brass product "Ring Sleeve Joint"

The outer diameter dimensions are small! The lightweight design allows for minimal space usage in fittings.

Brass products "Ring Sleeve Fittings" do not require any processing on the pipe section due to the connection relying on rings (beads). Tightening is achieved through a connection with a bag nut, eliminating the need for special tools, flames, or adhesives. After use, inspection, removal for redecoration, and reinstallation can be done easily. The fittings are nickel-plated, providing sufficient corrosion resistance and an aesthetically pleasing appearance. 【Features】 ○ Usable with oil, water, air, etc. ○ Can be used with any fluid that does not corrode copper and brass ○ The pressure can withstand considerable pressure (2.94 MPa) due to the ring completely adhering to the pipe under internal pressure (for resin pipes, up to 0.97 MPa) ○ The operating temperature range is -45 to 150°C for copper pipes and 0 to 60°C for resin pipes For more details, please contact us or download the catalog.

Expansion Joint

Expansion Joint

Supports up to 800℃! Prevents pipes from coming loose or breaking due to the expansion and contraction of metal caused by heat.

The "expansion joint" is a product that can absorb the expansion and contraction of piping with a structure that has peaks and valleys, similar to a flexible metal hose. By adding peaks to the pipe, it allows for expansion and contraction, just like a flexible tube. It is a joint that absorbs thermal expansion of piping caused by high-temperature gases, steam, or fluids, preventing the piping from coming apart or being damaged due to the expansion and contraction of the metal caused by heat. We also offer types that absorb pressure and vibration. 【Features】 ■ Structure with peaks and valleys ■ Can absorb the expansion and contraction of piping ■ Not constrained by blades ■ The bellows (tube) part can freely expand and contract ■ Made of stainless steel, capable of withstanding temperatures up to 800°C *For more details, please refer to the PDF materials or feel free to contact us.

Are you having trouble with unusual or special screws? Custom-made fittings production.

Are you having trouble with unusual or special screws? Custom-made fittings production.

Are you having trouble with SUS non-standard or special screws? We can manufacture custom fittings for you.

For example, if you want to connect a stainless steel PF1/2 (15A) female thread hose to an NPT1" (25A), normally you would need to connect the following three fittings: - Nipple [1] PF1/2 (15A) male thread - PT3/4 (20A) male - Socket [2] PT3/4 (20A) female - PT1" (25A) female - Nipple [3] PT1" (25A) male - NPT1" (25A) male If we can manufacture a nipple PF1/2 (15A) male thread - NPT1" (25A) male, it can be connected with just one fitting. In addition to pipe threads, American standard pipe threads, metric threads, unified threads, left-hand threads, and more, we also accommodate materials such as iron, brass, aluminum, etc., not limited to SUS. *For more details, please feel free to contact us.

No additional expenses for welding are required.

No additional expenses for welding are required.

Obtaining permits related to fire hazards, installing scaffolding and ventilation systems, etc.! There are various examples available.

If welding operations are eliminated, many indirect costs related to safety, labor, equipment, consumables, inspections, repairs, and monitoring will be unnecessary or significantly reduced. There are many examples, such as the installation of "sniff" areas, gas-free zones, rain shelters, fire monitoring systems, equipment, electrical cables, and purge lines. Additionally, ASME-certified welders will be freed from welding small-diameter pipes of 3 inches or less and can focus on welding larger diameter pipes or pressure vessels. 【Examples (partial)】 ■ Obtaining permits related to fire hazards ■ Installation of scaffolding and ventilation systems ■ Installation of "sniff" areas, gas-free zones, and rain shelters ■ Blank flanges/nozzles ■ Installation of fire monitoring systems ■ Installation of fire boxes/waterproof sheets *For more details, please refer to the PDF materials or feel free to contact us.
