Fractional Stainless Steel Seamless Tubing Data
Allowable working pressures are calculated from an S value of 20 000 psi (137 800 kPa) for ASTM A269 tubing at -20 to 100°F (-28 to 37°C), as listed in ASME B31.3, except as noted. multiply stainless steel rating by 0.94 for working pressure in accordance with ASME B31.1.
For Welded TubingFor welded and drawn tubing a derating factor must be applied for weld integrity. - For double welded tubing multiply pressure rating by 0.85
- For single welded tubing multiply pressure rating by 0.80
Suggested Ordering InformationFully annealed, high-quality (Type 304, 316, etc.) (seamless or welded and drawn) stainless steel hydraulic tubing ASTM A269 or A213, or equivalent. Hardness 80HRB (180 HV) or less. Tubing to be free of scratches, suitable for bending and flaring. |

Metric Stainless Steel Seamless Tubing Data
Allowable working pressures are based on equations from ASME B31.3 for EN ISO 1127 tubing (D4, T4 tolerance for 3 to 12 mm; D4. T3 tolerance 14 to 50 mm), using a stress value of 1370 bar (20 000 psi) and tensile strength of 5170 bar (75000 psi). except as noted.Multiply stainless steel rating by 0.94 for working pressure in accordance with ASME B31.1. For Welded TubingFor welded and drawn tubing, a derating factor must be applied for weld integrity: - for double-welded tubing, multiply pressure rating by 0.85
- for single-welded tubing. multiply pressure rating by 0.80.
Suggested Ordering InformationFully annealed, high-quality (Type 304, 316. etc) stainless steel tubing to EN ISO 1127 or equivalent. Hardness 180 HV (80 HRB) or less. Tubing to be free of scratches, suitable for bending or flaring. |
