Heat Treatment and Delivery Conditions
ASTM A335 pipes may be either hot finished or cold drawn with finishing treatment listed below:
1. Pipes of all grades of ASTM A335 except P5c, P23, P91, P92, P122, and P911 shall be reheated, and furnished in the
full-annealed, isothermal annealed, or normalized and tempered condition, the minimum tempering temperature for grades P5, P5b, P9, P21, and P22 shall be 1250°F (675°C), the minimum tempering temperature for grades P1, P2, P11, P12, and P15 shall be 1200°F (650°C). It is recommended that the temperature for tempering should be at least 100°F (50°C) above the intended service temperature; consequently, the purchaser should advise the manufacturer if the service temperature is to be over 1100°F (600°C).

2. ASTM A335 Pipe of Grades P1, P2, and P12, either hot finished or cold drawn, may be given a final heat treatment at 1200°F (650°C) to 1300°F (705°C) instead of heat treatments above-mentioned.

3. Pipe of grade P5c shall be given a final heat treatment in the range from 1325°F (715°C) to 1375°F (745°C).

4. ASTM A335 grades P92 & P911 shall be normalized at 1900°F (1040°C) minimum and tempered at 1350°F (730°C) minimum as a final heat treatment.

5. Grade P122 shall be normalized at 1900°F (1040°C) minimum, and tempered at 1350°F (730°C) minimum as a final heat treatment.

6. Grade P23 shall be normalized at 1900°F (1040°C) minimum with air cooling or accelerated cooling and tempered at 1350°F (730°C) minimum as a final heat treatment.

7. ASTM A335 P91 shall be normalized at 1900°F (1040°C) minimum, and tempered at 1350°F (730°C) minimum as a final heat treatment. Alternatively, liquid quenching and tempering is allowed for thicknesses above 3 inch when mutually agreed upon between the manufacturer and the purchaser. In this case the pipe shall be quenched from 1900°F (1040°C) minimum and tempered at 1350°F (730°C) minimum as final heat treatment.

boiler tube Packaging & Shipping
ASTM A335 Steel Pipes may be furnished bare or coated and with capped ends. Tubes and pipes up to 3” OD will be supplied in bundles. In order to prevent rust during sea shipment, bundles of ASTM A335 tubes may be wrapped with polypropylene sheets, and secured with flat steel bands. Over 3” OD will be supplied loose.
