Classification of pipe fitting hardness testing
Recently, a customer from Singapore placed an order for a batch of pipe fittings, including flanges, elbows, tees, and lateral tees. The customer specified that these pipe fittings must undergo hardness testing. Haihao Group is committed to providing customers with high-quality pipe fitting products and conducts comprehensive quality inspections, with hardness testing being one of our commonly used quality control methods. In the process of measuring metal hardness, we are proficient in various testing methods to ensure accuracy and reliability.

The classification of commonly used hardness test methods includes various techniques. Since the initial application of the Mohs hardness test, which involved scratching metal with minerals, in 1722, hundreds of methods for measuring metal hardness have been proposed. Among these methods, Brinell, Rockwell, and Vickers are more common and widely used hardness testing methods. In addition, there are methods such as the drilling method, the abrasive method, and the pendulum hardness test.
Hardness testing methods can be classified based on the rate of applying the test force and the magnitude of the test force. According to the magnitude of the test force, hardness testing methods can be divided into macrohardness testing, microhardness testing, supermicrohardness testing, and nanoscale hardness testing. Furthermore, hardness testing can also be classified based on test conditions, such as room temperature hardness testing, low-temperature hardness testing, and high-temperature hardness testing.
We place great emphasis on the accuracy and reliability of hardness testing. Therefore, when selecting hardness testing methods, we consider the principles of the test and the testing conditions to choose the most suitable method. Our experienced quality control team ensures that the hardness testing of products complies with relevant standards and requirements.
As a leader in the pipe fitting industry, Haihao Group will continue to dedicate itself to providing high-quality and reliable products. Through advanced quality control methods, we ensure that the performance of our products meets the expectations of our customers.
