Brinell Hardness Tester for Petroleum Machinery Equipment

The quality requirement of petroleum instrument is quite high. Leeb hardness tester and Vicker hardenss tester couldn't meet the test requirements. Generally speaking, users of this kind of equipment would ask the manufacturer to test the Brinell hardness value one by one, and specifically stipulate 3000kgf test force and 10mm carbide alloy ball indenter, or 750kgf test force with 5mm carbide alloy ball indenter. The traditional Brinell hardness tester is mainly applied in lab because of its large volume, heavy weight, and high requirement of test condition. 


At the end of 1990s, more and more petroleum machinery equipment accessories were exported, and there were more and more requirements for Brinell hardness testers. The king portable hydraulic Brinell hardness tester of America is brought into China and be widely used. However, the imported hydraulic Brinell hardness testers are more expensive and the manufacturer would not provide after sale service. Hardness tester is high accuracy testing instrument. There is high requirement of debugging and calibrating after perchasement, and that makes the imported product difficult to meet the requirement of maintaining and repairing for domestic users. Baded on the requirement for portable hardness testers in the domestic market, Shenyang Tianxing company manufactures three kinds of portable hydraulic Brinell hardness testers, they are PHB-3000, PHB-3000a and PHB-750.

There are three kinds of test force which are 3000kgf, 750kgf and 500kgf, and two kinds indenters which are 10mm and 5mm carbide alloy ball indenter. As long as clamping specimen, the test can be finished. The Brinell hardness test methods comply with relevant standards of the US and China.

Based on PHB-3000, the PHB-3000a Brinell hardness tester changes the support to a chain, and it is specifically designed to test Brinell hardness for large cylinder specimen.

PHB-750 is a magnetic Brinell hardness tester with test force of 750kgf, which is suitable for testing Brinell hardness of large, and huge specimen.

The above three kinds hardness testers manufactured by Shenyang Tianxing are all up to American and Chinese standards. The models of this kind of hydraulic Brinell hardness testers are more than foreign ones, and are more suitable for on site application in domestic market. Tianxing company sets up three domestic service centers to inspect instruments for users two times every year, ensuring the prompt, efficient and professional after sale service of the products.
