Application of seamless steel pipe in construction industry

Among the many pipeline materials, the most practical one is seamless pipe (SMLS), which is a relatively powerful pipeline material, not only because of the wide range of application fields and scope of this pipeline material, but more importantly, Because the quality of seamless steel pipe is very good, the quality of seamless steel pipe is the reason why this pipe material can be promoted and developed in the industrial field, the quality of seamless steel pipe is very good, this is the complex production process of seamless steel pipe Determined, the biggest feature of seamless steel pipes is that there are no seams on the pipe wall (capable of high pressure), while ordinary pipes have obvious seams, because of the small feature of seamless steel pipes, this kind of Types of piping materials can be used and promoted in the industrial field.

Seamless steel pipes are widely used. General-purpose seamless steel pipes are rolled from ordinary carbon structural steel, low-alloy structural steel or alloy structural steel, with the largest output. They are mainly used as pipes or structural parts for conveying fluids. Such steel manufacturing High-quality seamless steel pipes are widely used in hydraulic props, high-pressure gas cylinders, high-pressure boilers, fertilizer equipment, petroleum cracking, automobile half-axle sleeves, diesel engines, etc., and there are also many applications in the construction industry, such as stainless steel seamless pipes.

1. Application in decoration engineering. In addition to walls, cylinders, automatic retractable doors, rolling doors, ladder fence handrails, balcony handrails, rainwater downpipes, flagpoles, street light poles, arcade frames, kitchen and bathroom countertops, sinks, brackets, etc. in residential houses, The application is increasing day by day, the grade of steel used in decoration engineering is mostly 304, and 316 is also used.

2. The application of the roof. Early buildings that used stainless steel as roofs include the Savoy Hotel in London, the Eurostar Railway Station, the Chrysler Building in New York, and the Empire State Building.

3. Application in reinforced concrete. The selection of stainless steel bars in reinforced concrete structures is to improve the strength and resist the harsh marine environment and the corrosion of embedded steel bars by chlorides formed in concrete. Corrosion-resistant stainless steel concrete is used in the bridge decks of many marine buildings. 

4. In addition, more and more stainless steel structures are used in bridges, municipal construction cross-street bridges, awnings, corridors and other construction projects.
