1. Development Trend 1: Demand Orientation
According to the use environment, the design of the target material is an inevitable trend in the development of stainless steel pipes. For example, designing pipes for seawater environments to achieve resistance to pitting and stress corrosion cracking in seawater environments; for example, designing pipes for high-oxygen water environments; designing pipes with higher creep and radiation resistance, such as high temperature steam resistance Oxidized pipes can be used to achieve stainless steel pipes with different properties, such as high strength, high plasticity, high toughness, high corrosion resistance, and high purity.
Adapting to the needs of various industries and developing new materials suitable for different environments is an inevitable requirement for the development of stainless steel pipes. According to the national science and technology plan, the main solutions are: special environments such as transportation and treatment of dangerous goods, harsh environments such as waste gas treatment, high temperature environments such as ultra-supercritical, high pressure, and high corrosion, antibacterial environments such as biocompatibility, and high-purity use environments . Developing steel grades from the source, meeting different environments, and solving the performance and high purity requirements of stainless steel pipes are the requirements for the development of stainless steel pipes in the future.
2. Development Trend 2: Process Innovation
Innovative technology, energy saving and emission reduction to achieve green enterprises and green products are the main theme of the development of stainless steel pipes. Process innovation refers to the production and commercialization process of the development of new technologies, including existing or innovative products.
Major innovations in craftsmanship will lead to fundamental changes in the economic system of the industry. For example, cold extrusion rolling technology can save more than 50% of electricity. The rolling process does not use rolling oil, reducing the number of pickling passes, large deformation and improving the yield are all underdeveloped development trends. The product performance is better than the current rolling process. The specified grain size can be achieved according to the user's requirements for the product, and the same longitudinal and transverse tensile properties can be achieved. Consistent vertical and horizontal performance is an important parameter for application design. The application of steel pipe is mainly horizontal compressive and tensile strength. When the vertical and horizontal strengths are different, the material used in the design will choose the minimum steel tube thickness. When the vertical and horizontal directions are the same, the consumption caused by heterosexual differences can be saved, which is not only an important contribution to the green energy-saving development of enterprises, but also an important contribution to the whole society.
3. Development Trend 3: Management Innovation
"Digital Intelligent Factory", "Process Intelligent Service Platform", "Intelligent Safety Management", and "Computer Process Aided Design" are all platforms for management innovation, such as Songyang, Shangshang Desheng, etc., through computer simulation technology, to achieve cold working plasticity Deformation enables a controlled process and improves product performance. Through intelligent management, the company's production cost management, product quality, employee salary level and safety production have been raised to a higher level, and domestic stainless steel pipe enterprises will gradually move towards unmanned chemical plants, intelligent control of quality, and intelligent management. .Intelligent era of process, no casualties and on-time delivery.
4. Development Trend 4: Green Development
In the era of increasingly strict national and local environmental protection policies, zero discharge of waste liquid, waste water, solid waste and NO2 exhaust gas generated during the pickling process of stainless steel pipes is an inevitable trend of future development. Today, the development of technologies such as microfiltration, electrodialysis, membrane technology and limit crystallization provides technical feasibility for the surface treatment of stainless steel pipes to achieve zero discharge. At the same time, the application of zero-emission technology is not only a simple means to ensure environmental compliance and social benefits in the production of stainless steel pipes, but also the recycling of waste liquid, wastewater and sludge is practical. Economic benefits can reduce the production of stainless steel pipe manufacturers. The cost makes considerable economic sense.
5. Development Trend 5: Industrial Chain Extension
The enterprise product extension processing chain advances and retreats with the demand side. For example, Foshan Yundaxing Metal Technology Co., Ltd. produces 445J2 ferritic material large-diameter tubes. Start with extended processing for air conditioning. Only make tens of millions. For example, the small-diameter thin-walled coils produced by Jingning Chuangyue Metal have a wall thickness of more than 0.4mm, a single length of several kilometers, and a pipe diameter of more than 6mm. They are used for heat exchange tubes and signal tubes with thousands of tons per year. For example, Taiyuan Zhongjin Tianwei, which produces high-value-added national defense equipment with high-precision small-diameter special-shaped pipes. For example, Foshan Xinyuantong Metal Products Co., Ltd. focuses on the development of special-shaped section pipes and cooperates with foreign companies. It has thousands of tons per year. Anti-dumping and tariff hikes have nothing to do with it. For example, Wenzhou Zhengkang International and Shanghai Victrex focus on pipe fittings and water pipes, and have no worries about the market. Companies like this are also the way forward.
