The development of the stainless steel tube industry will go through the introduction period, growth period, maturity period and recession period. The law of market development remains unchanged, and the stainless steel pipe industry should look at the timing and wait for opportunities. The stainless steel market has entered the stage of brand competition, and market competition is intensifying. In order to gain more market share, stainless steel pipes must formulate new strategies based on market conditions and open up market segments. China's stainless steel market has entered the stage of development of brand and marketing competition from products and channels.
In the stage of brand and marketing competition, doing a good job in market segmentation has become the key to winning competition in stainless steel pipes. Many well-made stainless steel pipe companies are focused on doing a good job in market segments. Stainless steel pipes focus on introducing ecological and environmentally friendly products and opening up new market segments. With the continuous maturity of the stainless steel pipe market and the intensification of market competition, the future industry is “the market segmenter has the world”. The market segment will become the new corner of the stainless steel tube. The following is an overview and manufacturing method for the stainless steel tube for fluids.
Overview of fluid stainless steel tubes
The stainless steel tube for fluids has a hollow section with no welds from beginning to end. Compared with solid steel such as round steel, stainless steel pipe products have light weight when they have the same bending and torsional strength. They are economical section steels and are widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes and automobile drive shafts. , bicycle racks and steel scaffolding used in construction. The use of stainless steel tubes to manufacture ring-shaped parts can improve material utilization, simplify manufacturing processes, save materials and processing man-hours, such as rolling bearing rings, jack sleeves, etc., and have been widely used in stainless steel pipes.
Stainless steel pipes are also indispensable materials for various conventional weapons, and barrels, barrels, etc. are all made of stainless steel pipes. Stainless steel pipe products can be divided into round pipes and shaped pipes according to the shape of the cross-sectional area. In addition, the circular section is more uniform when subjected to internal or external radial stainless steel tube pressure, so most stainless steel tubes are round tubes.
Method for manufacturing stainless steel pipe for fluid
1 The general boiler tube use temperature is below 450 °C, and the domestic tube is mainly made of 10 or 20 carbon steel hot rolled tube or cold drawn tube.
2 High-pressure boiler tubes are often subjected to high temperature and high pressure conditions, and the tubes will oxidize and corrode under the action of high temperature flue gas and water vapor. Stainless steel pipe products are required to have high durability, high oxidation resistance and good structural stability.
1 General boiler tubes are mainly used to manufacture water-cooled wall pipes, boiling water pipes, superheated steam pipes, superheated steam pipes for locomotive boilers, large and small smoke pipes and arch brick pipes.
2 High-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, air guiding tubes, main steam tubes, etc. for high-pressure and ultra-high pressure boilers.
However, the round pipe also has certain limitations. For example, under the condition of being bent by the plane, the round pipe is not as strong as the square and rectangular pipe, and some agricultural machinery skeletons, steel wood furniture, etc. are commonly used square and rectangular pipes. Shaped stainless steel tubes of other cross-sectional shapes are also required depending on the application.
