Nominal pipe thickness is a key factor in influencing pipe nipple property, and according to different standards (ASME B36.10 or ASTM A733), the thickness is usually expressed as "schedule (SCH) or class.
1. Common pipe wall thickness classification
The schedule is American standard pipe specification, and the pipe wall thickness varies with the increase in diameter. Common specifications include:
SCH 10: Thin wall thickness, suitable for low-pressure and non-critical applications.
SCH 40: Medium wall thickness, the standard choice for industrial and commercial use, suitable for medium-pressure applications.
SCH 80: Thick wall design, suitable for high-pressure and high-temperature conditions.
SCH 160: Extra thick wall, suitable for extreme high-pressure environments.
2. Performance and application of different wall thickness
-
SCH 10 Pipe Nipple
Schedule 10 pipe nipple has a thin thickness, 1/2 inch pipe nipple only 1.65mm wall thickness.
SCH 10 pipe is light, and lower cost.
Sch 10 pipe thickness has strong fluid permeability and low pressure bearing capacity.
-
SCH 40 Pipe Nipple
SCH 40 pipe thickness provides medium thickness.
Schedule 40 pipe thickness has medium strength, and schedule 40 pipe nipple is suitable for industrial applications.
Schedule 40 pipe wall thickness has low fluid resistance and strong durability.
-
SCH 80 Pipe Nipple
Sch 80 nipple is thicker.
Schedule 80 nipples are suitable for high-pressure applications, with stronger shock resistance performance.
Schedule 80 nipples have excellent high-temperature resistance.
-
SCH 160 Pipe Nipple
Extra thick with schedule 160 pipe nipple.
Schedule 160 pipe nipple is specialized in extreme high-pressure conditions.
Schedule 160 pipe nipple has excellent wear and corrosion resistance properties.
3. Schedule 40 vs 80 steel pipe thickness
Schedule 40 nipple thickness is the standard in multiple applications, widely in medium-pressure and temperature pipe systems.
Usually, it is the first choice for industrial and commercial use.
Sch 80 nipple is thicker, and suitable for more high-pressure and temperature environments.
Sch 80 nipple provides higher strength and durability, but the inner diameter through which the fluid passes is smaller.
-
Performance Difference
Schedule 40 pipe nipples are suitable for Water supply, HVAC, low-pressure steam systems, etc. They have more pipe flow and are popular for those that need higher flow speed systems.
Schedule 80 nipples can withstand higher pressure due to their thicker wall thickness, which makes them suitable for high-pressure liquid or gas transportation, especially in the industry and petrochemical field. Due to the reduced inner diameter, the Sch 80 nipple has a slightly lower flow rate.
