Ratio of Wall Thickness to Outside Diameter. An analysis of each heat of steel shall be made to determine the percentages of the elements specified. When steel of different grades is sequentially strand cast, identification of the resultant transition material is required.

B For ovality values, the tolerance for average outside diameter at any one cross section does not exceed the outside diameter tolerance value wstm the applicable outside diameter. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

Ratio of Wall Thickness to Outside Diameter. If determined by the dial indicator method, the values obtained will be approximately twice those determined by the straightedge feeler gage method. Radii of Corners, max. Also see Footnote B. A These tolerances apply to cut lengths up to and including 24 feet.

Seamless steel tubing is a tubular product made without a welded seam. C The columbium plus tantalum content shall be not less than ten times the carbon content and not more than 1. Tubes to be used as hollow bar shall be furnished in round shape.

It is important to make sure that the strapping is very firm, so that the individual pipes can not move against each other and thereby suffer damage. It can also be used for structural applications; hollow pipe is far stiffer per unit weight than solid members.

Historical Version s – view previous versions of standard. Permissible Variations in Cut Length in. Therefore, the wall thickness can vary 15 percent over and under that specified, and the inside diameter is governed by both the outside diameter and wall thickness tolerances.

The tubes shall be made by a seamless process and by either cold working or hot working as specified. Within the text, the SI units are shown in square brackets.

ASTM A – 04 Standard Specification for Seamless Stainless Steel Mechanical Tubing

OD over 5 in. Nominal Pipe Size Inches.

The grades covered are listed in Table 1 and Table 2. You aatm contrast clearly with the package, usually it is applied in black color.

Specified Size, Outside Diameter, in. The steel may be cast in ingots or may be strand cast. B The titanium content shall be not less than five times the carbon content and not more than 0. It is usually manufactured by hot working steel and then cold finishing the hot-worked tubing to produce the desired shape, dimensions and properties All austenitic tubes shall be furnished in the annealed condition.

It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. A pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow — liquids and gases fluidsslurries, powders, masses of small solids.

Outside Diameter and Wall Thickness Tolerances. Twist In 3 ft. The average of maximum and minimum outside diameter readings ast fall within the outside diameter tolerances as shown in this table.
