Valve rubber is applied to the valve seal on the fluid end of mud pumps and fracturing pumps. It is usually polyurethane. The quality of polyurethane valve rubber directly affects the effect of fracturing operations. The use of poor quality rubber will lead to the scrapping of the valve body and seat. What's more serious will also cause the box to be scrapped so that personal safety accidents occur. Next, let us understand the application of valve rubber in the petroleum industry with Xinruituo.
Polyurethane valve rubbers are mainly used for sealing in the petroleum industry.
1. Polyurethane valve rubber is used for the valve seat seal of the drilling mud pump and the valve seat of the cement truck. It is a vulnerable part of petroleum equipment such as fracturing trucks, cementing trucks, plunger pumps, and mud pumps. It is also the rubber part matching the valve body of the mud pump used for drilling.
2. The rubber is made of polyurethane material. Polyurethane is the abbreviation of polyurethane, which is a kind of polymer material. Because of its excellent performance, it is widely used in many fields of national economy.
3. The full name of polyurethane is polyurethane, which is a general term for macromolecular compounds containing repeated carbamate groups on the main chain. It is formed by addition polymerization of organic diisocyanate or polyisocyanate and dihydroxy or polyhydroxy compound. Polyurethane materials are very versatile and can replace rubber, plastic, nylon, etc., and are used in airports, hotels, building materials, automobile factories, coal mines, cement factories, high-end apartments, villas, landscaping, colored stone art, parks, etc.
4. The mechanical properties of polyurethane are highly adjustable. By controlling the ratio between crystalline hard segments and non-crystalline soft segments, polyurethanes can obtain different mechanical properties. Therefore, its products have excellent properties such as wear resistance, temperature resistance, sealing, sound insulation, good processing performance, and degradability. Polyurethane is resistant to various acids, alkalis and organic solvents, so it is often used as a substitute for rubber products in harsh environments.
The above is the application of polyurethane valve rubber in the petroleum industry compiled and shared by Xinruituo. Shandong Xinruituo Precision Industry Co., Ltd. is a professional large-scale production enterprise dedicated to the research, development, manufacture and sales of polyurethane raw materials and products.
