Flange connections are a common and key component in piping and equipment systems, used to connect pipe sections, valves, pumps, and other components. The integrity of flange connections is directly linked to the safety and stable operation of the entire system. In flange connections, bolts play a key role in maintaining the integrity of the pipeline system. They must be tightened with sufficient torque to ensure that the system remains leak-free and functional despite pressure fluctuations, thermal expansion, or mechanical vibrations. Flange bolt torque technology involves controlling ......

Case hardening techniques play a crucial role in enhancing the surface properties of metal components. Among these techniques, Carburizing, Nitriding, and Carbonitriding are three of the most widely used methods. This article will introduce each process, compare their differences, and provide assistance in choosing the best surface treatment for specific applications. What Is Carburizing? Carburizing, also known as carburising and carburization, is a heat treatment and surface hardening technique designed to enhance the hardness and wear resistance of metal (usually steel) by allowing i......

Drill bits can be made of various materials; understanding the relative hardness of your drill bits compared to that of the material you are drilling is critical for the tool selection. Here we’ll explore the hardest or strongest drill bit material, carbide vs cobalt, and the best choice for hardened steel and stainless steel.  Strongest Drill Bit Material – What Are the Hardest Drill Bits? There are a few different materials that drill bits can be made of, with varying levels of hardness. The tungsten carbide is considered the strongest drill bit material and can work w......

A cutting speed that is too low or too high will harm the quality of machined parts and the life of tools in CNC manufacturing. How to set the best SFM in machining? In this article, we’ll dive into the SFM meaning and definition, its calculation formula, conversion between RPM and an SFM chart for different machining processes, and cutters. What Is SFM in Machining – SFM Meaning and Definition In CNC machining, SFM stands for surface feet per minute; it is a combination of surface speed and the unit feet per minute that defines the relative linear velocity between the cutting edg......

A clearance hole is necessary to permit a fastener to pass through a material without its threads gripping into it, what size should a clearance hole be for different fasteners such as a M4 screw or a 3/8 bolt. To determine its diameter, check out the clearance hole size chart for metric and imperial bolts, screws, and studs according to ASME B18.2.8 standard. What Is Clearance Hole? A clearance hole is a specific type of hole drilled in a material that is designed to allow a threaded fastener to pass through without engaging the threads. Is is distinct from a tapping drill hole, which ......
