Tungsten Carbide Choke Stem
Throttle valves are used for flow regulation or pressure regulation in various fluid operations. The choke stem is the most vulnerable part of the throttle valve. In such a structure, the choke stem is connected to the cone, and together with the valve seat and other components. They constitute the core part of the throttle valve. During the operation process, the cone and the valve stem will be eroded by the sand-containing fluid, and will be in a high-pressure and frequent vibration working environment for a long time.
Product Description
Cemented carbide choke stems are currently the most popular and well-received existence in the international market. Because during the operation process, once the wear exceeds the threshold of the valve, the cone and the stem will fall off, until the throttling channel is blocked, causing equipment failure and economic losses. This is a situation that no one wants to see.
In order to increase the service life of valves, major manufacturers have already used cemented carbide materials to replace traditional materials. In industrial fields such as petroleum, chemical industry, and energy, operators rotate the handwheel to make the throttle valve choke stem move axially to adjust the area of the throttle hole, thereby adjusting its flow and pressure environment. The valve choke stem faces not only the wear caused by repeated erosion of the fluid, but also special media and high-pressure environments. Therefore, the stable physical properties of the choke stem material are necessary and the primary characteristic.
Xingyu’s tungsten carbide throttle valve choke stem
The main material of the carbide throttle valve stem is tungsten carbide-based alloy. At the same time, we will also adjust the specific content and production process of the metal binder according to the specific needs of customers. Therefore, in the production process, YG6, YG8, YG10, YG6X and other grades are commonly used by us.
In our past orders for tungsten carbide choke stems, customers are mainly practitioners in the petrochemical industry from all over the world. We have our own relatively complete production lines, including blanks and fine grinding, as well as professional engineers and production personnel. Therefore, in most cases, as long as there are drawings, we can customize the production of corresponding products.
Since the establishment of our company, we have been deeply involved in the field of carbide for more than 25 years. In these 25 years, we have continuously provided carbide core components for equipment in the petrochemical field. For example, PetroChina is also one of our customers.
Tungsten carbide-based alloy has high hardness, high wear resistance, high compressive strength and excellent corrosion resistance. So if your equipment is also troubled by frequent wear and tear of parts and frequent equipment maintenance, you might as well try this more cost-effective material. Whether it is blanks or finely ground finished product, our four production lines can meet your different needs.
