Seamless High Carbon Steel Pipe A333 Grade 1 Oil Gas / Water Delivery Application

ASTM A333 covers nominal (average) wall seamless and welded carbon and alloy steel pipe intended for use at low temperatures. Several grades of ferritic steel are included. Some product sizes may not be available under this specification because heavier wall thicknesses have an adverse affect on low-temperature impact properties.

1. Standards:
ASTM A333: Standard Specification for Seamless and Welded Steel Pipe for Low-Temperature Service

2. Application:
Oil, Gas and water delivery;

Refinery, Boiler and Mechanical equipment manufacture;

structure construction; drilling, ship building and etc.

3. Ordering Information

Quantity (feet, centimeters, or number of lengths),

Name of material (seamless pipe),

Grade (Gr.1),

Size (NPS or outside diameter and schedule number of average wall thickness),

Lengths (specific or random),

End finish

Optional requirements

Test report required

4. Chemical Requirements

For each reduction of 0.01% carbon below 0.30%, an increase of 0.05% manganese above 1.06% would be permitted to a maximum of 1.35% manganese. When Grade 6 is ordered under this specification, supplying an alloy grade that specifically requires the addition of any element other than those listed for the ordered grade is not permitted. However, the addition of elements required for the deoxidation of the steel is permitted.
