Have you ever wondered how industrial valves are made? Without valves, the pipe system is incomplete. Valve manufacturers must deliver high-quality valves since safety and service life are the most important considerations in a pipeline process. What is the secret behind high-performance valves? Do the calibration machines make a difference? All of this, in fact, matters. Before delving into the finer points of an industrial valve, it’s necessary to first understand how valves are made.
Cast ᴍᴇᴛʜod
Turning is the process of removing excess material by cutting it using a lathe or a turning machine. It entails connecting the pre-shaped body to the amount as well as the turning machine. This machine spins at a high rate. A single-point cutter cuts the body into the desired and precise shape as it rotates. Among other things, turning can create grooves and holes. The next step is to apply a plating metal, usually per, to various parts of the body. Per plating ensures that the body is completely sealed.
The polishing of the body is the next step. The threads that allow certain valve parts to be attached to other components or pipes are then created by technicians. Because valves require holes, holing occurs as well. This is when regulations and standards come into play. Teflon or another form of elastomer is then applied to the valves.
Forged ᴍᴇᴛʜod
Following the selection of the material, the next step is to cut it into the required lengths and widths. The next step is to forge each part by partially heating it to a certain temperature. Trimming is the next step. This is where any excess material or burr is removed. After that, the body is flashed to give it the correct valve shape. The next step is sandblasting. The size of the sand used is determined by customer requirements or standards. The valves are first sorted to remove any that are defective. Machining improves the sizes and shapes of threads, holes, and other components, depending on the design and requirements of the customer. The surface of the valve is treated with various acids and other chemicals.
Pressure test
The valves must be pressure tested for leakage during the pressure test phase. In some cases, air at 6-8 bar pressure is used to fill the sd valve for a set period of time. It could take anything from 2 hours to a day, depending on the size of the valve. It could take anything from 2 hours to a day, depending on the size of the valve. Otherwise, the valve will advance to the next phase. Water pressure is used to detect leaks in some cases. This indicates that the valve can withstand the increased pressure. If there is a leak, the valve is returned to the warehouse. Before doing another set of pressure tests on this batch of valves, the technicians will look for leaks.
When the valve, on the other hand, shows internal leakage, it’s likely that the manufacturing ᴍᴇᴛʜods used aren’t up to snuff. In the video below, you can see the state-of-the-art valve manufacturing process as well as the incredible assembly process of the world’s largest valve.
