Understanding 1 1/2 x 3 1/2 Steel Tubes
Steel tubes are versatile construction materials used in a wide range of applications. One common size is the 1 1/2 x 3 1/2 steel tube, which refers to the outer dimensions of the tube. This article will delve into the characteristics, applications, and considerations when using this specific size of steel tube.
Dimensions and Weight
A 1 1/2 x 3 1/2 steel tube has an outside diameter of 1 1/2 inches and an outside width of 3 1/2 inches. The wall thickness can vary depending on the grade and application of the tube. Common wall thicknesses range from 0.095 inches to 0.188 inches. The weight of the tube per linear foot will vary based on the wall thickness and steel grade.
Steel Grades and Properties
Steel tubes are available in various grades, each with distinct properties:
- ASTM A500 Grade B: A commonly used grade for structural applications. It offers a good balance of strength and weldability.
- ASTM A501: Designed for cold-formed applications, this grade exhibits high tensile strength.
- ASTM A53 Grade B: A versatile grade suitable for general construction, mechanical tubing, and pressure piping.
- ASTM A106 Grade B: Specifically designed for high-temperature and high-pressure applications, this grade offers superior strength and creep resistance.
Applications
1 1/2 x 3 1/2 steel tubes find applications in various industries, including:
- Construction: Structural framing, handrails, support beams, and other structural components.
- Manufacturing: Machining, fabrication, and assembly of various products.
- Automotive: Frames, chassis, and other structural components.
- Agriculture: Farm equipment, fencing, and livestock enclosures.
- Industrial: Machinery parts, conveyors, and other industrial equipment.
Advantages
- Strength and Durability: Steel offers excellent strength and durability, making it suitable for structural and load-bearing applications.
