Schedule 80 Carbon Steel Pipe

Date:2022-11-11    keywords: schedule 80 carbon steel pipe
Schedule 80 Carbon Steel Pipe is made up of carbon steel materials. The carbon steels can vary in composition based on the grades. The strengths and the toughness vary. To have an international and equal identification of the pressure capacities of the pipes, the schedule scale is used. The Schedule 80 Carbon Steel Pipe means that it has schedule 80 characteristics. There are schedules 5 to 160. 5 is the least pressure capable and 160 is the most pressure capable.

So the Schedule 80 Pipe Dimensions would be in half way through the spectrum. The nominal bore sizes range from 1/8 inches through 6 inches and the internal and external diameters vary. This in turn affects the wall thickness to vary from 0.095mm to 0.432mm. So the Schedule 80 Pipe Pressure Rating depends on all of these factors; the wall thickness, the diameter and the material grade. The stronger materials don’t need to have thicker walls to be in schedule 80. The Schedule 80 Pipe Thickness In Mm ranges only from 0.095mm to 0.432. The applications of the carbon steels pipes are in the less corrosive, high toughness and high wear and tear applications. The Schedule 80 Pipe Weight differs based on the grade, wall thickness, diameter and length of the pipe.

High pressure resistance, high precision, cold bending deformation, no crack flattening, no oxide scale, good tensile and impact resistance.

Difference Between SCH 40 and SCH 80 Steel pipe

Pipes with Schedule 40 come with standard weight, and pipes with schedule 80 come with extra strength. The materials used for making Schedule 40 and Schedule 80 come from the same material.

Schedule 80 pipes have a thicker wall than Schedule 40 pipes. As such, Schedule 80 pipes are stronger than Schedule 40 pipes. Though both pipes are used in construction work, Schedule 40 is used more often. But if a stronger pipe was needed, then the engineers would go for Schedule 80 pipes. Schedule 80 pipes are used where the pipes have to be exposed. But if there is no need for any extra strength, Schedule 40 pipes are sufficient.
