ASTM A500 Structural Welded Pipe

ASTM A500 Structural Tube Product Introduction

ASTM A500 structural tube is a standard specification for cold-formed welded structural tubing, with a nominal diameter of circular tube. ASTM A500 is the most commonly used hollow structural profile specification in North America. Because ASTM A500 is a structural specification, circular hollow structural steel tubes manufactured according to this specification are suitable for structural applications and general building uses. A500 has stricter tolerances than A53, resulting in higher quality and less variability in A500 circular hollow structural steel tubes. Circular hollow structural steel tubes have excellent surface finish and are unpainted. A500B structural tubes are designed for applications requiring higher strength, tighter tolerances, and superior surface finish. This product is ideal for painted applications.

Manufacturing Process of Structural Pipes

ASTM A500 structural steel pipes are welded pipes made from flat rolled steel through roll forming and resistance welding. Longitudinal butt joints of the welded pipes should be welded along the pipe wall thickness to ensure the structural design strength of the pipe section. Internal burrs are typically not removed from welded structural steel pipes.

Advantages of ASTM A500 Structural Pipes

Strength: High-strength steel (HSS) offers an extremely high strength-to-weight ratio, excellent compressive strength, and torsional strength.

Appearance: In exposed applications, particularly in Exposed Structural Steel (AESS) applications in buildings, HSS provides an ideal visual effect for building and other structural designs.

Consistency: The consistency of HSS in dimensions, shape, strength, and tolerances makes its performance entirely predictable, which is especially important for demanding Original Equipment Manufacturer (OEM) applications.

Ease of Machining: HSS is easy to bend, form, punch, and drill. Improved connection designs make it easier to join HSS with other structural materials, further enhancing the ease of on-site machining.

Cost-Effectiveness: Due to its higher strength-to-weight ratio, especially A1085 HSS, HSS is cost-competitive with other structural materials. Improved connection and fastening methods often provide a cost advantage.

Fire Resistance: HSS is fire-resistant and will not deform, twist, crack, expand, or shrink. Stability: It is resistant to dry rot and mold.
