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.
SCH 80 steel pipes have strong resistance to high pressure, high temperature and chemical environments, and their high pressure resistance is more than twice that of SCH40, making them more suitable for use in petrochemical, natural gas and other high-pressure fluid transmission pipelines. In addition, its good corrosion resistance is unmatched by other pipes. After rigorous testing, SCH80 steel pipe can operate stably for a long time in chemical, acid and salt corrosive environments.
High pressure resistance, high precision, no deformation during cold bending, no cracks and flattening, no oxide scale, good tensile and impact resistance.
How to choose SCH 80 steel pipe correctly?
When selecting SCH 80 steel pipes, factors such as usage environment characteristics, working pressure, working temperature and service life need to be taken into consideration. In situations where high temperature and pressure are required or where high strength and corrosion resistance are required, it is more appropriate to choose SCH80 steel pipes; if it is in general situations, it means that SCH40 or thinner pipes can also meet the needs. SCH80 steel pipes are not only unnecessary, but also increase the cost. cost. Of course, there are various types of SCH80 steel pipes, such as galvanized, seamless, welded, etc. The corresponding pipe material and type need to be selected according to the specific environment and usage requirements.
SCH 80 pipe has thicker walls and requires more material and more manufacturing time, which increases costs. When selecting pipe for a specific application, it is important to consider the pressure requirements and the cost-effectiveness of selecting thicker, more expensive pipe.
