How To Buy Steel Tube

How To Buy Steel TubeSteel Friend offers a comprehensive selection of tubing in various forms and grades, catering to a wide range of industrial needs. Whether you require large structural carbon tubes for construction projects or specialized small OD tubes for aerospace applications, we've got you covered.

  1. Understanding Tubing Basics If you're new to purchasing tubing, it's essential to grasp some basic concepts to streamline the process. Here are the fundamentals to help you navigate:

  2. Identifying Steel Type and Grade Like all steel products, the first step is determining the type of steel and its grade. For instance, you would specify whether you need "Carbon Steel" (the type) and "A500 GR B/C" (the grade).

  3. Selecting Tube Shape Steel tube comes in various shapes, including round, square, and rectangular, among others. While round, square, and rectangular are common shapes, specialty shapes like hexagon or oval may require special production runs. Feel free to inquire about these shapes, and we can provide a custom quote.

  4. Understanding Tube Measurements Unlike pipe, which is measured by inner diameter and schedule, tube is measured by its Outer Diameter (OD) and Wall Thickness (WT). Additionally, tube measurements may include terms like "Average Wall Thickness" or "Minimum Wall Thickness," providing insights into the tube's thickness consistency.

  5. Choosing Seamless or Welded Tubing It's crucial to determine whether you need Seamless or Welded tubing. Seamless tubing has no visible weld seam, whereas Welded tubing features a noticeable weld seam. Additionally, we offer Drawn over Mandrel (D.O.M.) Tubing, a welded product with the weld seam removed, providing a seamless appearance.

  6. Common Grades and Specifications At Steel Friend, we supply a variety of tubing grades and specifications to suit different applications. For instance:

    TypeGrade/Specification

    Drawn over Mandrel (DOM) TubingASTM A513 TY 5
    Round Mechanical TubingElectric Weld (ERW), Cold Drawn Seamless
  7. Length and Quantity Requirements To provide an accurate quote, we'll need to know the length and total quantity of tubing needed, regardless of the grade or specification.
