DONGSHANG Stainless produces welded stainless steel elliptical tubing including elliptic and flat oval tubing two shapes, SS 203, 304/L, 316/L grades.
Mechanical tubing is a type tubing used for mechanical and structural applications, there are varieties of shapes and finishes for choosing, so mechanical tubing is wide used for wide applications。
Our production facilities provide full range of standard mechanical steel tubing sizes to meet customers need, we offer various shapes mechanical tube solutions for the most applications, for example, building / construction / architecture industries.
ASTM A554 Welded Mechanical Tubing
ASTM A554 is standard specification for welded stainless steel mechanical tubing, it defined the detailed requirements for tubing manufacturer, such as dimension, grade, forms, condition, tolerance.
Of course, mechanical tubing is not limited to ASTM A554 specification, other standards are available for special applications,
Stainless Steel Material
Stainless steel have high strength and perfect corrosion resistance, these properties make tubing durable, and not easy to damage, there are various finishes to be offered for different purpose, therefor, stainless steel a ideal material for mechanical and structural applications.
304 stainless steel is a common grade, 304L, 316L and other grades are used depending on applications.
Sizes and Dimensions
We offer a wide variety of sizes for tubing used in mechanical purpose, outside diameter ranges from 6 mm to 406.4 mm, minimum wall thickness is 0.51, these are common sizes for round tubing, special sizes tubing can be offered upon request in large quantity, like particular heavy wall and thin wall tubing.
Forms and Shapes
Beside round tube, we can also offer shaped tubes, such as square tubing, rectangular tubing, oval tubing, bending tubing.
Conditions and finishes
As welded is most common condition for mechanical tubing, tubing is welded without stress-relieving or annealing, generally, cold drawn and bead removed processes are not required, these conditions are main reasons why mechanical tubing is cost effective。
There are various stainless steel tubing finishes to opt, polishing finishing is usually required for ornamental and decorative purpose, common grit include #180, #320, #400 and mirror polishing.
