New opportunities for the development of stainless steel welded pipes
Posted by： Hangao Time：3/26/2025 9:05:35 AM
Stainless steel welded pipe as an important basic material in the industrial field, with its excellent corrosion resistance, high strength and good processing performance, is widely used in petrochemical, food medical, building decoration, environmental protection energy and other fields. In recent years, with the upgrading of global manufacturing and the rise of emerging industries, the stainless steel welded pipe industry has ushered in a new round of development cycle, but also faces the challenges of technological iteration, environmental protection requirements and increased market competition.
First, industry status: demand diversification to promote market expansion
Energy transformation drive: Hydrogen energy storage and transportation pipelines, nuclear power equipment cooling system for high-precision stainless steel welded pipe demand surge;
Environmental protection policies increase: Environmental protection projects such as sewage treatment and flue gas desulfurization promote the increase in the purchase of corrosion-resistant pipes;
Consumption upgrade demand: the penetration rate of food-grade stainless steel welded pipe in dairy products, wine and other industries continues to increase;
Emerging application scenarios: new energy vehicle battery shells and ultra-thin precision tubes for semiconductor equipment have become new growth points.
Second, technological breakthrough: intelligent manufacturing and process innovation
Laser welding technology: the use of fiber laser welding instead of traditional TIG welding, welding speed increased by more than 3 times, weld strength close to the base metal level;
Automatic production line upgrade: AI visual inspection system is introduced to realize real-time identification of weld defects, and the product pass rate is increased to 99.5%;
Material research and development breakthrough: The application of new materials such as biphase steel and super austenitic steel to meet the needs of extreme working conditions such as deep-sea oil and gas pipelines and LNG ultra-low temperature environment.
Challenge and response: Cost pressure and green transformation
Raw material price fluctuations: nickel, chromium and other alloy costs accounted for more than 60%, 2023 LME nickel price fluctuations led to pressure on corporate profits;
Upgrading of environmental standards: pickling wastewater treatment and VOCs emission restrictions force enterprises to invest in environmental protection equipment, and small and medium-sized manufacturers face the risk of elimination;
International trade barriers: Europe and the United States frequently anti-dumping investigations on China's stainless steel pipe, export-oriented enterprises need to open up the "Belt and Road" new market.
Stainless steel welded pipe industry is shifting from "scale expansion" to "quality and efficiency" development stage. Under the dual drive of the "double carbon" goal and the upgrading of the manufacturing industry, enterprises need to take technological innovation as the core, and build the competitiveness of the whole value chain from material research and development to terminal services, in order to occupy a favorable position in the reconstruction of the global industrial chain.
