Schedule 80 pipe is thicker than schedule 40 pipe. Look at the above formula of schedule number, allowable stress for material at a given temperature is fixed. That means with an increase in service pressure schedule number will increase which is a pipe wall thickness designator.
ASME 31.3 Allowable Pressure CalculatorExample - Allowable Pressure in a Steel Pipe. The allowable pressure in a 4 inch schedule 40 carbon steel pipe with outside diameter 4.5 in, wall thickness 0.237 in and allowable stress 16000 psi, can with quality factor E for steel 0.8 and wall thickness coefficient 0.4 be calculated as. p = 2 (0.237 in) (16000 psi) (0.8) / ((4.5 in) - 2 (0
Maximum allowable pressure is calculated with the Barlow's formula for A53 Grade B Seamless and Welded Standard Steel Pipe with Yield Strength 35000 psi and design factor 0.7.. Allowable stress used in the Barlow's formula is calculated as (35000 psi) 0.7 = 24500 psi Note! - in codes like ASME B31.3 modified versions of the Barlow's formula - like the Boardman formula and
Allowable Working Pressures (Type 304L)The allowable stress values used are shown in table A-3 of the ASME Code for Pressure Piping B31.1 1989 Edition for welded pipe to SA-312 with a weld joint efficiency of 0.85. Allowable working pressures shown reflect the minimum wall thickness.
Compare Schedule 40 & Schedule 80 Pipe and FittingsThe following property table overviews and compares Schedule 40 and Schedule 80 for its thickness, size, and maximum working pressure for fluids. Consider this chart and pressure ratings for pipe sizes whenever wanting to determine the compatibility of the pipe schedule
The material standard for such thickness pipes has no limitations, you could ask sch 40 stainless steel pipe, like ASTM A312 Grade 316L; Or sch 40 carbon steel pipe, such as API 5L, ASTM A53, ASTM A106B, A 179, A252, A333 etc.. Summary:Pipes with Schedule 40 come with a standard weight, and pipes with Schedule 80 come with extra strength.
