Vickers hardness

Vivtorinox hardness test is a kind of indentation test method, which can be used to measure the hardness of thin metallic materials and surface layer. It has the main advantages of the method of the method of the law of the family and the law of the law, but it is simple and easy to use, but it is not easy to use the method of the Vivtorinox method.

Hardness test

Stainless steel tube inner diameter above 6.0 mm, wall thickness in 13mm following annealing of stainless steel tubing can used to W-B75 type Merriam Webster Hardness Meter, it tests the very fast and easy, suitable for of stainless steel pipes do quick and nondestructive inspection. The inner diameter of the stainless steel tube is larger than 30mm, and the wall thickness is larger than that of 1.2mm stainless steel pipe. The hardness of HRB and HRC is tested by using the hardness tester. Stainless steel tube inner diameter greater than 30mm, wall thickness less than 1.2mm of stainless steel pipe, using the surface of the hardness tester, test HRT or HRN hardness. The inner diameter is less than 0mm, more than 4.8mm of stainless steel pipe, using the tube special for the hardness tester, test HR15T hardness. When the inner diameter of the stainless steel pipe is larger than 26mm, the hardness of the inner wall of the tube can be tested by the tester of the surface of the tube or the surface of the hardness tester.


Variety of stainless steel pipe connection, the common types of pipe fittings with compression type, compression type, connection type, push, push threaded, socket welding and connecting flange connection, welding and welding with the traditional connection derived from a combination of series connection mode. These connections, according to its principle of different, the scope of its application is also different, but most of the installation is convenient, reliable and reliable. Connection with the seal or gasket materials, most of them selected in line with the requirements of the national standard silicon rubber, nitrile rubber and ternary ethylene propylene rubber, eliminating the user to worry about.
