What is seamless steel pipe?
Seamless steel pipe (smls pipe) is a steel pipe made by heating, perforating, rolling and cooling steel billets. Compared with welded pipes, seamless steel pipes have obvious advantages in appearance and performance. First of all, its inner and outer walls are smooth, without welds and oxide scales, which not only reduces fluid flow resistance, but also prevents the fluid from being contaminated, thus ensuring better transportation quality. Secondly, seamless steel pipes have excellent strength and pressure resistance. Their structures are simpler, more durable, can withstand higher pressures and temperatures, have a longer service life, are not prone to rupture, and are more suitable for high-pressure and high-precision working environments.
What does SCH 80 mean in pipe?
SCH 80 in pipe represents wall thickness, which refers to XS thickened pipes with a pressure wall thickness less than DN200mm. Usage scenarios generally involve high temperature, high pressure, and highly corrosive conditions. The wall thickness of SCH 80 grade pipes is relatively thick, and the pressure and temperature in the use environment must comply with ASME/ANSI standards to ensure the safety and reliability of the pipeline system. SCH 80 grade piping systems are often used in the manufacture of chemical equipment, high-pressure pipelines, high-temperature heaters and some special piping systems. When designing and installing a steel pipe system, it is necessary to select the appropriate pipe number according to the actual use environment to ensure the stability and safety of the pipeline system.
Features of sch 80 seamless stainless steel pipes
1. Corrosion resistance: Seamless stainless steel pipes have good corrosion resistance, especially to chloride ions and oxidants. In corrosive media such as acid, alkaline, salt solution and sea water, its corrosion resistance is much higher than that of ordinary steel pipes.
2. High strength: Seamless stainless steel pipes have high strength and stiffness, can withstand high pressure and gravity, and have good earthquake resistance.
3. Aesthetics: Since no welding process is used during the manufacturing process, the seamless stainless steel pipe has a smooth surface, no welds, and is not easy to accumulate scale, so it has good aesthetics and cleanliness.
4. Easy maintenance: Seamless stainless steel pipes have good self-cleaning properties and are not easy to accumulate scale and breed bacteria. Therefore, maintenance is easy and only requires simple cleaning and disinfection.
5. Long service life: Seamless stainless steel pipes have a long service life, generally more than 50 years, and will not suffer from rust and corrosion problems like ordinary steel pipes during use.
