Our stainless steel cylinders have achieved the world’s top-class clean performance with Rmax from 1 to 3s required for semiconductor production through precise inner surface polishing, and have been used by many major chemical manufacturers. For stainless steel welded cylinders, we conduct solid solution heat treatment to remove internal stress after performing advanced welding processing, and conduct x-ray inspection for all products to ensure the welding quality.

* We are capable of manufacturing stainless steel cylinders that meet the laws and standards of each country, such as Korea (KGS) and China (GB).

Our general seamless cylinders can be used for a variety of industrial gases used at factories and construction sites. They are manufactured by cutting a seamless pipe made of materials such as manganese steel into a standard length, hot-working the piece, and molding a cylinder having a concave or convex bottom or a double-ended shape. In addition, advanced heat treatment is performed to manufacture general seamless cylinders with excellent pressure resistance and safety.

We offer seamless aluminum alloy cylinders and FRP cylinders as an authorized agent of Luxfer, the world’s largest aluminum gas cylinder manufacturer. Seamless aluminum alloy cylinders are lightweight and corrosion-resistant and ideal for high-purity gases and medical gases. We also offer a wide range of FRP cylinders that are lighter than aluminum ones.

We offer special welded cylinders of various sizes from small quantities to 7,000 L. The accuracy of polishing of the c cylinder inner surface can be specified. We can handle all kinds of high-purity gases by performing blasting, acid cleaning, barrel polishing, and composite electrolytic polishing. We also manufacture various cylinders for LP gases for automobiles and forklifts. dissolved acetylene gases.

We have been supplying LP gas cylinders for households, stores, and factories, pursuing quality improvement and safety for many years. Furthermore, we have developed a new light-weight LP gas cylinder having a thin body plate, using our unique welding and processing technology. We have reduced the weight of a 50-kg cylinder by about 1 kg compared to a conventional one.

We manufacture LP gas bulk storage tanks of various sizes from 150 kg to 2,900 kg, using our proprietary precision welding technology. Our LP gas bulk storage tanks have many features unique to SK Cylinder, such as a leg structure that facilitates installation and a double seal structure with a gasket and an O-ring that prevents minute leakage from the flange.
