Description

Stainless steel rectangular tube is a type of hollow long steel strip with a rectangular cross-section, so it is called a rectangular tube. It is widely used in scaffolding frame structures such as petroleum, natural gas, water, gas, steam, etc. In addition, when the bending and torsional strength are the same, it is lighter in weight, so it is also widely used in the manufacturing of mechanical parts and engineering structures. It is also commonly used for the production of various conventional weapons, barrels, shells, etc. Classification of stainless steel rectangular pipes: Square pipes are divided into two categories: seamless steel pipes and welded steel pipes (welded pipes). According to the shape of the cross-section, it can be divided into square and rectangular pipes. Circular steel pipes are widely used, but there are also some irregular steel pipes such as semicircles, hexagons, equilateral triangles, and octagons.

Dimensional Tolerances

Dimensional Tolerances
Outside Diameter:		Twist:	Maximum twist per 3 feet of length
Largest outside dimension	Outside tolerance including convexity and concavity	Longest outside dimension
up to 2 1/2"	±.020"	2" to 2 1/2"inclusive	.062"
over 21/2" to 31/2" inclusive	±.025"	over 21/2" to 4" inclusive	.075"
over 31/2" to 51/2" inclusive	±.030"	over 4" to 6" inclusive	.087"
over 51/2"	±1%	over 6" to 8" inclusive	100"
Tolerances include allowance for convexity or concavity. For rectangular sections, the tolerance calculated for the larger flat dimension shall also apply to the smaller flat dimension. This tolerance may be increased 50 percent when applied to the smaller dimension, if the ratio of cross sectional dimension is between 1.5 and 3, and 100 percent when the ratio exceeds 3.		over 8"	112"
		Straightness: Permissable variation shall be 1/8" times the number of feet of total length divided by 5:
		.125" x (total length) ÷ 5
Wall Thickness:		Squareness of Sides:
Maximum allowable variation	±10%	Adjacent sides may deviate from 90° by a tolerance of plus or minus 2 degrees maximum.
(wall thickness is to be measured at the center of the flat, exclusive of the weld area, and not at the corners)
Worner Radii:		Flash:
The radius of any outside corner shal not exceed three times the specified wall thickness		Structural tubing usually is supplied flash-in. The height of the flash will vary with the wall thickness of the tube.
