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. 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.

Ratio of Wall Thickness to Outside Diameter. Specified Size, Outside Diameter, In. The average of maximum and minimum outside diameter readings should fall within the outside diameter tolerances as shown in this table.

If secondary melting processes are employed, the heat analysis shall be obtained from one remelted ingot or the product of one remelted ingot of each primary melt. Nominal Pipe Size Inches. Radii of Corners, max. Tensile Strength, min ksi MPa. 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.

Through a correct and complete marking of packaging will create the conditions to avoid misuse, accidents, wrong delivery, mass and volume losses and customs penalties. 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. Max Curvature in Total Lengths, in. Where ellipses … appear in this table, there is no requirement and analysis for the element need not be determined or reported.


Outside Diameter, Tolerance,B in. When steel of different grades is sequentially strand cast, identification of the resultant transition material is required.

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

It can also be used for structural applications; hollow pipe is far stiffer per unit weight than solid members. If determined by the dial indicator method, the values obtained will be approximately twice those determined by the straightedge feeler gage method.

This abstract is a brief summary of the referenced standard. Stainless Steel Seamless Tubes: An analysis of a51 heat of steel shall be made to determine the percentages of the elements specified. This specification covers seamless stainless tubing for use in mechanical applications where corrosion-resistant or high-temperature strength is needed.

ASTM A511 Seamless Stainless Steel Mechanical Tubing

Tolerances Hot Finished Round Table. Within the text, the SI units are shown in square brackets. The steel may be cast in ingots or may be strand cast.

Largest Specified Outside Dimension, Inches. 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.

Yield Strength min, ksi MPa. The straightness tolerance is 0. Subject to transport, duration and turnover can be wrapped in eg plastic jute fabric and is provided at the bundle ends and stop points with sheet metal bundled pipes. OD over 5 in.

A The usual procedure for measuring straightness is by means of a 3-ft 0. Seamless steel tubing is a tubular product made without a welded seam. A These tolerances apply to cut lengths up to and including 24 ft 7. The values stated in each system ast, not exact equivalents; therefore, each system shall be used independently of the other. Wenzhou Sunrise Import and Export Co. Referenced Documents purchase separately The a51 listed below are referenced within the subject standard but aetm not provided as a511 of the standard.


B The titanium content shall be not less than five times the carbon content and not more than 0. We warmly welcome you to buy the quality and durable steel products from our factory. A For small diameter or thin wall tubing or both, where many drawing passes are required, a maximum of 0.

ASTM A511, ASTM A554, ASTM A778

The grades covered are listed in Table 1 and Table 2. Tubes to be used as hollow bar shall be furnished in round shape. Specialty coatings, such as of PE, require padding to ensure that the protective layer is not damaged.

Small outside diameter tubes are defined as those under a 0. The grades covered are listed in Table 1Table 2and Table 3. For Wall Thickness, Given, in.

B 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. Tolerances — Diameter, Wall— Round Tubing. The tubes shall be made by a seamless process and by either cold working or hot working as specified.
