STEEL & COPPER TUBING Steel tubing is called out by outside diameter and wall thickness. For hydraulic plumbing a low carbon welded steel tubing should be used which can be bent and flared without cracking. Order "hydraulic grade" tubing. Pressure ratings in this table are based on a tubing with tensile strength of 55,000 PSI, and were calculated by Barlow's formula: P = 2t x S O, in which P = burst strength in PSI, t = wall thickness, S = tensile strength in PSI, and O = outside diameter. This formula may be used to calculate tubing sizes not listed. All dimensions in the table are in inches. For hydraulic plumbing, a safety factor of at least six should be used and ratings for this factor are shown in the table. For pressure rating at other safety factors, take burst PSI and divide by desired safety factor. Copper Tubing Data Burst pressures are calculated by Barlow's formula: P = 2t x S O, in which P is burst pressure PSI; t is tubing wall thickness; S is ultimate strength of material (32,000 PSI for copper); and O is outside diameter of tubing.
