SSAW Steel Pipe Sizes

1. SSAW Steel Pipe Standard Size Range

Standard sizes typically range from 219.1 mm (8 in) to 3048 mm (120 in) in outside diameter, with wall thicknesses from 5 mm to 25.4 mm. Standard lengths are 6 m, 9 m, and 12 m, with custom dimensions available upon request.

2. Common Diameter Categories

The following diameter ranges are commonly specified for different applications.

2.1 Small to Medium Sizes (16–36 in)

16–20 inch SSAW pipes are commonly used for municipal water transmission, drainage systems, and low-pressure pipeline projects.

24–36 inch SSAW pipes are widely used for medium-pressure oil and gas pipelines, bridge structures, and industrial construction projects, providing a balance between capacity, strength, and cost.

2.2 Large Sizes (40–60 in)

40–60 inch SSAW pipes are generally selected for high-capacity water transmission systems, long-distance oil and gas pipelines, and large infrastructure projects for projects requiring higher flow capacity.

2.3 Extra-Large Sizes (72–100+ in)

72 inch and larger SSAW pipes are mainly manufactured for special engineering applications such as offshore platforms, marine pipelines, dredging projects, and large water diversion systems. Most orders are manufactured to project specifications.

3. SSAW Steel Pipe Size Chart

The following chart lists the available outside diameters, wall thickness ranges by steel grade, and standard production lengths for SSAW steel pipes.These dimensions are commonly supplied for oil and gas transmission, water pipelines, piling, and structural applications. Custom sizes are also available upon request.

Note: Wall thickness values are shown in millimeters (mm). Blank cells indicate that the corresponding size and grade combination is not typically manufactured.

4. Common SSAW Pipe Sizes by Application

The following table summarizes the most common size selections.

Note: The dimensions above represent commonly specified ranges. Actual pipe sizes depend on design pressure, transportation medium, and applicable project standards.

5. SSAW Pipe Size Selection Checklist

Before ordering an SSAW steel pipe, confirm the following:

✓ Required flow rate

✓ Design pressure

✓ Steel grade

✓ Applicable standard

✓ Pipe dimensions (OD × WT × Length)

✓ Surface coating

✓ Inspection requirements

✓ Transportation method

Besides standard sizes, Huaxi Steel also supplies custom SSAW steel pipes based on project requirements. Outside diameter, wall thickness, length, steel grade, coatings, end preparation, and inspection requirements can all be customized.

6. FAQs

Q1. What sizes are available for SSAW steel pipes?

Standard SSAW steel pipes are commonly available from 219.1 mm (8 in) to 3048 mm (120 in) in outside diameter, with wall thickness depending on the selected diameter, steel grade, and applicable standard.

Q2. What is the standard length of an SSAW steel pipe?

Standard pipe lengths are typically 6 m, 9 m, and 12 m. Custom lengths are also available to meet project specifications, transportation requirements, and installation conditions.

Q3. How do I choose the correct SSAW pipe size?

Select pipe size according to the required flow rate, design pressure, steel grade, and applicable standard. Both outside diameter and wall thickness should be specified to ensure the required pressure rating.

Q4. Can SSAW steel pipes be manufactured in custom sizes?

Yes. In addition to standard dimensions, SSAW steel pipes can be manufactured with custom outside diameters, wall thicknesses, lengths, coatings, and end preparations, subject to applicable standards and mill manufacturing capabilities.

Q5. What wall thickness is available for SSAW steel pipes?

Available wall thickness varies with the pipe diameter and steel grade. Standard wall thickness ranges from 5 mm to 25.4 mm. Heavier wall thicknesses are available for high-pressure or project-specific applications.
