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
| Chemical Composition % Gr. 1 |
| Carbon (C) max | Manganese (Mn) | Phosphorus (P) max | Sulfur (S) max | Silicon (Si) | Nickel (Ni) | Chromium (Cr) | Copper (Cu) | Aluminum (Al) | Vanadium (V) max |
| 0.3 | 0.40-1.06 | 0.025 | 0.025 | … | … | … | … | … | … |
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.
5. Manufacturing Process
Raw Material Inspection → Cold Centering → Heating → Piercing &
Rolling → SIzing → Heat Treatment → Testing → Finishing → NDE →
Visual & Dimension Inspection → Marking → Storing & Shipping
