Description

ASTM A500 structural welded pipe

ASTM A500 standard specification for Cold-Formed Welded and Seamless Carbon Steel Structural Tubing in Rounds and Shapes

Manufacture process

ASTM A500 structural pipe is a welded pipe size pipe made of flat steel, formed by a roller system, and welded using resistance welding. The longitudinal butt joint of the welded pipe shall be welded over its entire thickness to ensure the structural design strength of the pipe section. Welded structural steel pipes are usually installed without removing internal flash.

Benefits of structural welded pipe

1. Strength: It has a high strength-to-weight ratio, excellent compression support characteristics and excellent torsional strength.

2. Appearance: In exposed applications, especially in the application of architectural exposed structural steel (AESS) in buildings, it provides the preferred visual opportunity for the design of buildings and other structures.

3. Uniformity: It has uniform size, shape, strength and tolerances, which makes its use completely predictable and is especially important for demanding OEM applications.

4. Easy to make: It can be easily bent, formed, stamped and drilled. The improvement of the connection design used to fix the structural pipe on itself or other structural materials also improves the ease of on-site manufacturing

5. Cost-effectiveness: Due to its high strength ratio, especially in A1085, it is cost-competitive with other structural materials. Through improved connection and fastening methods, it usually has a cost advantage.

6. Resistance: It is fire resistant and will not warp, twist, split, expand or shrink.

7. Consistency: It resists dry rot and mold.

*Applies to specified wall thicknesses (t) equal to or greater than 0.120". For lighter specified wall thicknesses, the minimum elongation values shall be calculated by the formula: % elongation in 2" = 56t+17.5, rounded to the nearest percent.
** Applies to specified wall thicknesses (t) equal to or greater than 0.180". For lighter specified wall thicknesses, the minimum elongation values shall be calculated by the formula: % elongation in 2" = 61t+12, rounded to the nearest percent.
*** Applies to specified wall thicknesses (t) equal to or greater than 0.120". For lighter specified wall thicknesses, the minimum elongation values shall be by agreement with the manufacturer.
