![]() This tube at the point of manufacture goes through a process where the internal weld bead is rolled. It is not suitable for applications requiring significant flaring, expanding or bending. AW tube has a higher yield point than annealed tube and is generally used for decorative applications or in mildly corrosive conditions. This tubing is produced direct off the continuous tube welding mill, using cold rolled stainless steel strip made to ASTM standards, with tube produced to commercial limits of straightness in standard or specific customer lengths. The tubular products system incorporates a comprehensive range of stainless steel fittings in the form of elbows, tees, reducers and flanges in various sizes, wall thickness, grades and finishes to suit tube dimensions and tolerances. Tube is usually annealed if extensive forming and bending is required, such as for bending or expanding. Stainless steel tube can be joined by welding, which facilitates rigidity in construction, or using mechanical fittings which enables dismantling for hygienic cleaning. Finishes are selected to suit application and aesthetic appeal. Unpolished has a 2B mill finish, standard polished is a finely grit polished finish and there is a finer buffed finish giving close to mirror appearance. It is usually manufactured by the processes of longitudinal welding, hot and cold drawing (seamless) or spiral welding.įinishes or appearance range from unpolished to highly polished. Tube is manufactured in round, square and rectangular sections in a variety of wall thicknesses. It is resistant to many forms of corrosion, has hygienic sterile properties, high quality aesthetic appeal and exceptional strength. Stainless steel tube is typically specified as OD (outside diameter) and WT (wall thickness) and mechanical properties of the base stainless steel material.

For lengths over 24ft, an additional over tolerance of 1/8 in. These tolerances apply to cut lengths up to an including 24 ft.Therefore the wall thickness can vary 15% over and under that specified, and the inside diameter is governed by both the outside diameter and wall thickness tolerances. For those tubes with inside diameter under 1/2 in (or under 5/8 in when the wall thickness is more then 20% of the outside diameter) which are not commonly drawn over a mandrel, A is not applicable.Therefore the wall thickness can vary 12 1/2% over and under that specified. Many tubes with wall thicknesses more then 25% of outside diameter or with wall thicknesses over 1 1/4 in.For Ovality values, the tolerance for average outside diameter at any one cross section does not exceed the outside diameter tolerance value for the applicable outside diameter. ![]() ![]() When the wall thickness is more then 20% of the outside diameter.) Are as shown in this table except that wall thickness tolerances are 10% over and under the specified wall thickness.
