CZSD Seamless Pipe Technology Corporation is a national high-tech enterprise dedicated to the research and development and application of high-performance stainless steel seamless pipes.
The company has research and development platforms such as a national-level seamless steel pipe engineering technology research center for nuclear power and a post-doctoral workstation.
The company mainly develops, produces and sells various carbon steel, alloy steel and stainless steel seamless steel pipes. Since its establishment, the company has been focusing on the R&D and manufacturing of various types of high-performance and high-value-added seamless steel pipes. Its product applications include power station boilers, aerospace and navigation, petrochemicals, and automobile manufacturing.
The company has broken the international monopoly of Japan’s Sumitomo, France’s Vallourec, etc., and provides a favorable guarantee for the nationalization of high-performance, low-cost raw material accessories for China’s green, environmentally friendly and energy-saving large-scale power plant boiler manufacturers in innovative applications and promotion of the international market.
Among them, T91, T92, TP347H, TP347HFG, super stainless steel S30432 and other high-performance seamless steel pipes have a market share of more than 60% in the field of seamless steel pipes for small-diameter high-pressure boilers in China, and have become China’s leading enterprises in this segment and standard setter.
The company’s seamless steel pipes can be used in the fields of solar thermal power generation, hydrogen energy and nuclear power. The small-diameter seamless pipe of stainless steel products developed by the company has passed the type test evaluation of the National Iron and Steel Product Quality Supervision and Inspection Center.
In May 2021, the company sent samples to Dongfang Boiler Materials Research Institute and Harbin Boiler Plant Materials Research Institute for comprehensive performance evaluation tests (including high-temperature creep tests of more than 10,000 hours), which are expected to be completed in the second half of 2022. After the evaluation is completed, the small-diameter stainless steel seamless pipe will be the highest-grade domestic stainless steel material for the current ultra-supercritical unit.
The company’s competitive position in the field of small-diameter stainless steel seamless pipes for power station boilers continues to increase. In 2021, the domestic small-diameter stainless steel boiler tubes purchased by the three major power plant boiler plants in China will account for more than 50% of the total purchased small-diameter stainless steel tubes. The annual output of power station boilers in China’s three major power station boiler plants accounts for about 75% of the national power station boiler output, and the company’s market share of small-diameter stainless steel seamless pipes exceeds 60%.
