KN-6082 High-Temperature Foaming Characteristic Apparatus

The tendency of oils to foam at high temperature can be a serious problem in systems such as high-speed gearing, high volume pumping, and splash lubrication. Foaming can cause inadequate lubrication, cavitation, and loss of lubricant due to overflow, and these events can lead to mechanical failureRead more >

It is a good laboratory special-purpose instrument in petroleum chemical industry, transporRead more >

KN-130J Metal Bath Copper Strip Corrosion Tester

KN-130J Metal Bath Copper Strip Corrosion Tester conforms to the ASTM D130 Standard Test Method for Corrosiveness to Copper from Petroleum Products by Copper Strip Test and ASTM D4048 Standard Test Method for Detection of Copper Corrosion from Lubricating Grease. This tester is suitable for testing aviation gasoline, jet fuel, motor gasoline, natural gasoline, or other hydrocarbons with Reid vapor pressure not exceeding 124kPa (930mmHg), solvent oil, kerosene, diesel, distillate fuel oil, lubricRead more >

KN-4048 Grease Copper Strip Corrosion Apparatus

KN-4048 Grease Copper Strip Corrosion Apparatus conforms to ASTM D4048 Standard Test Method for Detection of Copper Corrosion from Lubricating Grease. It can measure the tendency of lubricating grease to corrode copper under specific static conditions. It may be of some value in predicting possible chemical attack on lubricated parts, such as bearings that contain copper or copper alloys. Such corrosion, for example, can cause premature bearing failures. However, no correlations with actual fielRead more >

KN-1743 Corrosion Preventive Properties of Lubricating Greases

New, cleaned, and lubricated bearings are run under a light thrust load for 60 6 3 s to distribute the lubricant in a pattern that might be found in service. The bearings are exposed to water, then stored for 48 6 0.5 h at 52 6 1°C (125 6 2°F) and 100 % relative humidity. After cleaning, the bearing cups are examined for evidence of corrosionRead more >

KN-1838 LPG Copper Strip Corrosion

Copper corrosion limits provide assurance that difficulties will not be experienced in deterioration of the copper and copper-alloy fittings and connections that are commonly used in many types of utilization, storage, and transportation equipment.Read more >

KN-1384 Corrosion Test for Engine Coolants

this test method will generally distinguish between coolants that are definitely deleterious from the corrosion standpoint and those that are suitable for further evaluation.however, the results of this test method cannot stand alone as evidence of satisfactory corrosion inhibition. the sctual serivice value of an engine coolant formulation can be determined only by more comprehensive bench,hynamometer,and field testsRead more >

KN-B117 Salt Spray Corrosion Test Chamber

Brief introduction to structural design The salt spray test box has the advantages of beautiful appearance, reasonable structure, smooth and smooth lines. The shell adopts high quality flame retardant PP plastic board, durable temperature greater than 85 DEG C, between the board and the board of the joint by planing and milling after a 90 degree angle, then using the high temperature molten plastic welding torch welding wire fill, after cooling solid weld, the whole body of the joint box formatiRead more >

KN-4340 Corrosion of Cast Aluminum Alloys in Engine Coolants

It is essential that engine coolants prevent heat-transfer corrosion of aluminum cylinder heads during engine operation. Any corrosion products formed may deposit on interior radiator surfaces, reducing heat-transfer efficiency of the radiator. Overheating and boil-over of the cooling system may then occurRead more >

KN-2809 Apparatus for Cavitation Corrosion and Erosion-Corrosion Characteristics

KN-2809 Apparatus for Cavitation Corrosion and Erosion-Corrosion Characteristics conforms to ASTM D2809 Standard Test Method for Cavitation Corrosion and Erosion-Corrosion Characteristics of Aluminum Pumps with Engine Coolants. This test method can be used to distinguish between coolants that contribute to cavitation corrosion and erosion-corrosion of aluminum automotive water pumps and those that do not. It is not intended that a particular rating number, as determined from this test, will be eRead more >
