A GUIDETO PIPE SIZES

Pipe Strengths

To identify the dimensions and strengths of different pipe, it is common to use ‘schedule’ terminology taken from the ANSI pipe schedule chart. The pipe schedule chart on the following page provides specific details about the most common types of pipe that we have available including:

•Schedule 5•Schedule 10•Schedule 20•Schedule 30•Schedule 40•Standard Weight

(STD)•Schedule 60

•Extra Strong (XH)•Schedule 80•Schedule 100•Schedule 120•Schedule 140•Schedule 160•Double Extra

Strong (XXH)

PIPEContinuous Buttweld This is a general purpose pipe for use in steam, gas and air lines. It is not intended for close coiling, bending or high temperature service. No minimum mechanical properties are specified for this product, but it is typically stocked with a standard black lacquer coating. Continuous buttweld meets ASTM A-53 Type F Specifications (which has replaced the obsolete ASTM A-120 Specifications.)

Electric Resistance Welded (ERW)This pipe is suitable for welding, coiling, bending, flaring and flanging. It is pressure tested and is typically stocked with a standard black lacquer coating with plain beveled edges. ERW meets ASTM A-53 Gr. B Type E Specifications.

Seamless PipeThis carbon steel pipe is lower in cost than its butt weld and ERW counterparts. It is most applicable where precise dimensions and high-pressure requirements are of utmost importance. It also meets ASTM A-519 specifications.
