At the recently concluded seminar on high-grade seamless steel pipe production for power station boilers, the physical quality of SUPER 304H and HR3C seamless steel pipes for ultra-supercritical power plant boilers developed by the entire process of TISCO was assessed to have reached the international advanced level of similar products. With the global energy and environmental problems becoming more and more serious, the development of an efficient and clean large-capacity super (super) critical power station boiler is an inevitable trend. However, the use environment of key components of ultra-supercritical units is extremely harsh on the performance of materials. In the past, it can only rely on imports, seriously restricting the development of ultra-supercritical boilers in China. Since 2005, TISCO has developed many complete sets of SUPER304H and HR3C seamless steel pipe technology for the ultra-supercritical power plant boilers that fit the characteristics of our equipment and processes. Both products have the characteristics of high temperature creep rupture strength, good resistance to high temperature steam corrosion and good cold and hot processing performance, fully meet the design requirements of power station boiler industry. Products have passed the Shanghai Power Generation Equipment Design Institute of the complex re-evaluation, the China Machinery Industry Federation organized the identification of new products industry and the National Boiler and Pressure Vessel Standardization Technical Committee review, and adopted a number of domestic well-known boiler Technical Review, in-kind Quality reached the international advanced level of similar products. It is learned that over the years, TISCO has continuously developed a series of seamless steel tubes for boilers for substation, supercritical and supercritical power plants. These products have been widely used in well-known domestic enterprises. Among them, the three kinds of products produced by TISCO are widely used in China's super (super) critical power stations and become the designated suppliers of the three major power tubes and pipes in China. A sucker rod coupling is a mechanical device used to connect two sucker rods together in an oil well pumping system. Sucker rods are long, threaded steel rods that are connected end-to-end to form a continuous rod string. These rod strings are used to transmit the pumping motion from the surface to the downhole pump, which is located in the oil well.

The sucker rod coupling is typically made of steel and has internal threads that match the external threads on the sucker rods. It is designed to provide a secure and leak-proof connection between two rods, ensuring that the pumping motion is efficiently transmitted down the well.
Sucker rod couplings come in various sizes and designs to accommodate different rod diameters and thread types. They are typically made to withstand high tensile loads and harsh operating conditions, such as high temperatures and corrosive environments.
Proper installation and maintenance of sucker rod couplings are essential to ensure the integrity and performance of the pumping system. Regular inspections and replacements are necessary to prevent coupling failures, which can result in production downtime and costly repairs.
