YN-Coupling Joints, thanks to their great fl exibility and economy, are steadily replacing the fl anged pipe joints nowadays, from various industrial plants to vessels. These YN-coupling joints are not only to eliminate the welding costs, but also prevent any linear expansion and defl ection of the pipes by welding repairs. YN-Couplings are the easiest way to join and repair pipes of all materials.
They require no special tools or pipe-end preparation.
They are fl exible, lightweight and fi reproof and are used in shipbuilding, wastewater treatment, general industry and the construction sector. YN-Couplings come fully assembled and ready to install. A torque wrench is the only tool required to do the job. YN-Couplings are used to join and repair any plain end pipes or tubes including steel, stainless steel, ductile iron, FRP, PVC, CPVC, C900, concrete pipe, copper and CuNi piping.

e static caused by the ball and seat friction are grounded to avoid fi re or explosion. The stem incorporates the blow-out proof design. The stem and body have excellent sealing performance with redundant steam seals and a graphite gasket on the gland plate. They also have cavity relief design and double lock and bleed.
Swivel joints have been optimally designed for ball bearing race. This is considered as high pressure application. It is the best design for high twist stress and optimized heat treatment on ball race. The point contact is designed to reduce friction factor.
With accumulated experiences and production knowhow, the company is currently supplying a variety of items ranging from auxiliary products for heavy electrical machinery to general industrial products.
Among the maker’s hott est-selling items are LED traffi c safety arrows.
The fi rm’s other popular items include gas insulated switchgear (GIS)-transporting covers. Made of plastic resin, the products eff ectively solve the problems of ordinary steel products. Very light, they allow the user to conduct the installation work by himself, thus helping save time and labor costs.
The company has acquired an international patent (PCT) for its mixing head assembly with double tilted injection nozzle system. With the unique technology, it is capable of making foaming machines which show superior mixing quality by stable laminar fl ow. It originally started in the PU business with its innovative mixing head, a core PU technology, and since then has constantly expanded its business fi eld to all the PU applications.
