Medical oxygen regulators are precision devices which control oxygen pressures up to 2,000 and even 3,000 psig (per square inch gauge) and regulate this pressure to allow patients to receive the proper prescription of oxygen. Oxygen Conserving Devices and Regulators are pressure reducing devices designed to regulate or lower oxygen pressure from a cylinder to levels that can be safely used by the patient. A Regulator simply regulates the (free) flow from an oxygen cylinder.Oxygen regulat …

Shell Dot 4: Your Quality Brake Fluid IntroductionBrake fluid is a type of hydraulic fluid used in hydraulic brake and hydraulic clutch applications in automobiles, motorcycles, and light trucks. It is used to transfer force into pressure and to amplify braking force. It works because liquids are not appreciably compressible.Shell DOT 4 Brake and Clutch fluid is long-lasting and has a low viscosity. It is suitable, especially for anti-braking systems, electronic stability control s …

Dispersants are chemicals that are sprayed especially on a surface oil slick, to break down the oil into smaller droplets that are distributed or spread over a large volume of water which are more readily mix with the water. Dispersants do not reduce the amount of oil entering the environment, but push the effects of the spill underwater. Dispersant contain compounds such as surfactant that lowers the interfacial tension of molecules with both water-soluble and oil soluble component, which …

Surface Preparation of Marine Vessels For CoatingCoating is the most cost-effective way of providing protection for corrosion and to prolong the lifespan of marine vessel and other offshore structures. Paint and preservative coatings can be found on both interior and exterior surfaces of a ship with separate areas being coated differently according to their particular kind of exposure. Before paint can be effective as an anticorrosive, the substrate to which it is to be applied must be thoroughl …

An alkyd is a polyester modified by the addition of fatty acids and other components. The term alkyd is a modification of the original name "alcid", reflecting the fact that they are derived from alcohol and organic acids. Alkyds are used in paints and in moulds for casting. They are the dominant resin or binder in most commercial "oil-based" coatings. Alkyd paint or oil based paint, is popular in applications that require a high gloss, durable finish. They are the most suitable choic …
