Stainless steel cylinder with 1/4" needle valves for purging and admitting LPG samples. K40000 LPG Copper Strip Corrosion Test Cylinder: ORDER UP TO 4 TEST CYLINDERS (sold separately) Complete test consists of LPG Corrosion Test Cylinders, Water Bath, Copper Strips, Polishing Materials and the ASTM Copper Strip Corrosion Test Standards. After one hour the test strip is removed and compared against the ASTM Copper Strip Corrosion Standards. Some solvent mixtures have been used successfully for dip-polishing.Tests the corrosiveness of LPG to copper by immersion of a polished test strip in the sample inside a test cylinder at elevated temperature. ![]() The article is usually dipped or wiped with a suitable solvent and then dried. Circular and band saws usually produce the best surfaces, and they can be used in most sawing operations.Īn effective method of eliminating fine surface scratches and producing a high gloss on cellulose plastics is solvent polishing. Some of these saws, however, are better suited for sawing plastics because they produce smoother or faster cuts than others. Tenite can be sawed with any saw used for wood or metal- circular saws, band saws, saber saws, jigsaws, hacksaws, or handsaws. An electric strip heater set at optimum profile temperature may be used for hot bending.ĭrills designed especially for plastics are available, and their use is suggested for drilling Tenite cellulosic plastics however, standard twist drills used for drilling metal or wood can be satisfactory as long as speeds and feed rates are kept modest. The maximum amount of bend will depend on the extruded shape, thickness, and rate of deflection. Hot or cold bending can be used to produce simple shapes from Tenite profiles. In general, the highest speed at which overheating the tool or plastic does not occur will give the best results. Tool speeds should be such that the plastic material does not melt from frictional heat. Tenite can be worked with most tools used for machining wood or metal.
