This specification covers square and rectangular tubing, manufactured with thesame stringent mill controls and quality assurance systems used to produce allSwepco tubular products. Welding machines, operators and procedures are A.S.M.E.code qualified.
Square and rectangular tubing in sizes through 12" outside dimension, up to 1/2"wall thickness is produced with a single longitudinal weld seam. Larger sizesand heavier wall thicknesses will have two weld seams.
Continuous lengths to 40 feet long are available.
The following conditions and tolerances apply to standard production material.However, tubing can be produced to applicable parts of A.S.T.M. A-500 (cold formedwelded and seamless carbon steel structural tubing) when requested.
The outside dimensions for square or rectangular
Outside Dimensional Tolerances Rectangular and Square Tubing
The above tolerances do not include an allowance for concavity or convexity. Allmeasurements will be taken at a point not less than 2" in from either end.
The chemical and mechanical properties of the finished tubing will equal or exceedthose of the raw material specified.
The outside corner radius will be no greater than three times the nominal wallthickness specified.
The maximum twist in each 3 feet, based on the greatest side dimension, will be as follows:
The straightness tolerance for any tube will not exceed an amount calculated using the following formula.
Each length of tubing shall be legibly marked with the name Swepco, size, grade of material and heat number.
