Supplying high quality and high precision high-pressure gas cylinders that meet cutting-edge needs to all industrial fields around the world
SK CYLINDER offers a variety of gas cylinders that meet cutting-edge needs, ranging from LP gas cylinders for household use to semiconductor material gas and medical gas cylinders. We supply high quality and high precision products to all industrial fields around the world.
Stainless steel cylinders
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).
Stainless steel welded cylinders are prepared with an internal volume of 1.0/3.4/10.0/40.0 L. Other specifications are made to order.
General seamless cylinders
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.
Seamless manganese steel cylinders are prepared with an internal volume of 1.0/1.25/2.1/3.4/6.8/10.1/13.4/20.1 L. Other sizes and seamless chrome-molybdenum steel cylinders are made to order.
Aluminum alloy and FRP cylinders
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.
Seamless aluminum alloy cylinders for medical use are prepared with an internal volume of 2.0/3.0/9.4 L, FRP cylinders for medical use with that of 1.1/2.0/2.8 L, and seamless aluminum alloy cylinders for carbon dioxide with that of 7.0/10.5 L. Other specifications are made to order.
Special welded cylinders
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.
LP gas cylinders for forklifts are prepared with an internal volume of 36/47 L, and dissolved acetylene gas cylinders for forklifts with that of 3.6/12.5/24.0/41.0 L. LP gas cylinders for automobiles and fluorocarbon cylinders are made to order.
LP gas cylinders
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.
LP gas cylinders are prepared with a gas volume of 2/5/8/10/20/30/50 kg. For those with 20/30/50 kg, we also offer aluminum alloy cylinders separately. Other specifications are made to order.
LP gas bulk storage tanks
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.
LP gas bulk storage tanks are prepared with a gas volume of 150/200/300/500/980/2000/2400/2900 kg, and underground bulk storage tanks with that of 300/500/990/2900 kg. Other specifications are made to order.
We make made-to-order high-pressure gas cylinders with optimum specifications for various production applications.
SK CYLINDER manufactures made-to-order high-pressure gas cylinders with optimum specifications to meet the laws and standards as well as production applications of each country.
