Steel Pipe & Round Tube

Steel pipe and round tube provide reliable strength, dimensional uniformity, and consistent performance across structural, mechanical, and industrial applications. These round profiles support load transfer, alignment, reinforcement, and flow-related functions across numerous markets, making them essential components in construction, fabrication, and manufacturing.

Central Steel Supply Company stocks specification-compliant steel pipe and round tube in a wide range of diameters, wall thicknesses, grades, and standard lengths. The following sections outline available design options, grades, processing capabilities, and common applications.

Dimensions, Grades, and Value-Added Support

Steel Pipe (NPS Format)

Central Steel Supply Company stocks steel pipe in Nominal Pipe Size (NPS) designations with wall thicknesses primarily in Schedule (SCH) 40 and 80, depending on size and grade. Standard lengths include 21 feet and 42 feet. Additional non-stocked sizes can be coordinated through trusted partner resources when specialized dimensions are required.

Round Mechanical & Structural Tube (OD + Wall Format)

Steel round tube is stocked in a variety of Outside Diameter (OD) and wall thickness combinations. Standard lengths vary by product type and specification. Additional diameters and wall thicknesses can be coordinated when specialized sizing is required.

Boiler Tubes – ASTM A178

Central Steel Supply Company stocks ASTM A178 boiler tube—also referred to as heat exchanger tube and pressure tube—for mechanical, heat-exchange, and boiler applications requiring consistent performance under elevated temperature and pressure. Material is available in various outside-diameter and wall-thickness combinations, with additional sizes coordinated through trusted partner resources when specialized dimensions are required. The ASTM A178 specification covers electric-resistance-welded carbon steel boiler and superheater tube used in steam-generation and pressure-retaining systems.

Value-added services can be coordinated to supply pipe and round tube to specified lengths, supporting customer fabrication and installation operations by allowing labor and equipment to remain focused on core production and assembly tasks. This approach reduces preparation requirements in both the shop and the job site, minimizes waste, enhances efficiency, and strengthens long-term business relationships by contributing to the overall success of each customer’s business.

Processing Services for Steel Pipe & Round Tube

Central Steel Supply Company facilitates processing services designed to support customer efficiency, optimize processing operations, and reinforce strong business relationships. Advanced equipment and trusted partner resources allow pipe and round tube to be supplied to precise dimensional requirements, contributing to smoother fabrication and installation workflows.

  • Saw Cutting: Precision saw cutting—including miter-cut capabilities where applicable—allows pipe and round tube to be supplied in required lengths, supporting dimensional accuracy and reducing preparation time in both shop and job-site environments.

Note: Drilling, punching, slotting, and cutouts are not offered on round pipe or round tubing. These capabilities apply only to square and rectangular tubing, which will be detailed in the dedicated document.

CAD File Integration

CAD files and detailed shop drawings can be imported directly into machine programming, enabling precise control over hole placement, slot geometry, and cutting operations. Central Steel Supply Company maintains a full CAD department capable of developing or refining CAD drawings when required, enhancing dimensional accuracy and process efficiency. These capabilities support the overall success of each customer’s business by improving process consistency, reducing delays, and helping projects progress more efficiently through fabrication and installation stages.
