Schedule 40 "and" schedule 80 "refer to the reference charts issued by the American National Standards Association (ANSI).
schedule 80 pipe
When it comes to seamless pipes, the different timetable refers to the size, thickness and maximum pressure of the pipeline.
Smaller planned pipelines are cheaper than larger planned pipelines. According to the volume and pressure of materials required to move along the pipeline, different timetables provide material cost choices. If the low-pressure drain pipe is being installed, the seamless Schedule 40 pipe is enough and the cost efficiency is higher than the seamless pipe of schedule 120.
