ASTM A333 Gr 6 Pipe Weight Chart

The pipe complied to Nominal Dimension standard ASME B36.10M. (NPS or outside diameter and schedule number of average thicknes). Meanwhile, some pipe sizes may not be available under the ASTM A333 standard, as heavier wall thickness have an harmful on impact properties. In case client have special requirements shall follow the supplementary specification in ASTM A333. When ordering ASTM A333 pipe (including ASTM A333 6 pipe), list the required NPS/OD, wall thickness (or schedule), length (random or fixed), end preparation (plain, beveled, or threaded), heat treatment condition, and impact test requirement. Confirming these inputs upfront helps keep the ASTM A333 Grade 6 specification consistent across production, inspection, and site acceptance.

Differences Between Each Grade

If you are comparing ASTM A333 Gr 1, Gr 3, and Gr 6, start from the project minimum temperature, required toughness, and material availability. Grade 6 is widely used as a general low-temperature carbon steel option, while other grades are selected when the service condition or alloy requirement is more specific.

As we know ASTM A333/A333M pipe could be manufactured in seamless or welded, so in which cases to use seamless type and when to use welded type?

In case of ASTM A333 Grade 4 steel pipe, it shall be made by the seamless process.

If welding process in EFW or ERW with filler metal added, and fabricated of pressure vessel quality plates.

ASTM A333 Pipe Heat Treatment Options

All the seamless and welded steel pipe, except ASTM A333 Grade 8 and Grade 11, shall be treated to control the micro-structure in one option as follows,

1. Normalized in a uniform temperature not less than 815℃ [1500℉], and cool in air or in the cooling chamber of an atmosphere controlled furnace, or after this heat treatment then heating to a suitable temperature to do the termpering.

2. Besides above heat treatment option, and with manufacturers will, reheat material to a suitable tempering temperature.

3. In case the seamless steel pipe in the ASTM A333, reheat and control hot working and the temperature of the hot finishing operation to a finishing temperature range from 845 to 945℃ [1550 to 1750℉], and cool in air or in a controlled atmosphere furance from an initial temperature more than 845℃ [1550℉]. For the ASTM A333 seamless steel pipe in Grade 1, Grade 6, and Grade 10 could be heat treated from a uniform temperature more than 815℃ [1500℉], then quenching in liquid and reaheat to a suitable tempering temperature, this type of heat treatment could replace the above plan also provided the ASTM A333 4.3.1. For the ASTM A333/ A333M Grade 8 and Grade 11, heating treatment shall be complied the standard specification.

For the ASTM A333 Grade 1, Grade 6 and Grade 10 steel pipe, and it is not allowed to add the chemical element not specified in the specification, but it is allowed to add the element for the deoxidation of steel.

Why Choose Octal for ASTM A333 Grade 6 Pipe

Low-temperature service is unforgiving: what usually slows projects down isn’t the pipe body itself, but toughness proof + traceability. Octal supplies ASTM A333 Grade 6 pipe (ASTM A333 6 pipe / A333 ASTM) with a documentation-first workflow that aligns to EPC/owner review. Each order can be supported with an acceptance-ready pack that ties the pipe marking to the paperwork—typically including EN 10204 3.1 MTC (showing ASTM A333 Gr 6 chemical composition and mechanical results), Charpy impact test reports at the specified test temperature (often referenced as the “ASTM A333 temperature range” requirement), dimensional inspection records (OD/WT, length, straightness), and a heat/lot traceability list that maps heat numbers to pieces. Where the project calls for it, third-party inspection and release notes can be coordinated so the submittal is cleaner and needs fewer revisions. The end result is simpler: the offer matches the ASTM A333 pipe specification you issued, and the shipment arrives with the documents needed to pass receiving inspection without rework.

FAQ

Q1: What is ASTM A333 Grade 6 pipe used for?
A1: ASTM A333 Grade 6 pipe is used for low-temperature pressure service where the project requires verified toughness. It’s commonly specified for cold-service process piping and pipeline systems where Charpy impact testing is part of acceptance.

Q2: What is the ASTM A333 temperature range for Grade 6?
A2: In procurement and engineering practice, “ASTM A333 temperature range” usually refers to the required impact test temperature and the project design minimum temperature. ASTM A333 Grade 6 is commonly impact tested at −45°C (−50°F) unless the project specifies a different test temperature and acceptance criteria.

Q3: What is the ASTM A333 Gr 6 chemical composition requirement?
A3: ASTM A333 Gr 6 chemical composition is controlled by the specification limits for key elements (such as C, Mn, P, S, and Si) to support weldability and low-temperature toughness consistency. For bid comparison and incoming inspection, buyers should confirm the chemistry limits on the MTC and ensure they match the applicable ASTM A333 edition and any project supplements.

Q4: What information should I provide when ordering ASTM A333 6 pipe (ASTM A333 pipe)?
A4: For an accurate quote and acceptance-ready supply, provide the pipe size (NPS/OD), wall thickness or schedule, length (random or fixed), end preparation, required grade (ASTM A333 Gr 6), test temperature/impact requirement, heat treatment condition, and document level (MTC + test records). This avoids mismatched offers and reduces approval delays.
