ASTM A519 Steel Pipe

ASTM A519 carbon and alloy steel mechanical tubing used in the mechanical tubing may be cast in ingots or may be strand cast.

The ASTM A519 steel pipe, often referred to as mechanical tubing, stands as a testament to engineering excellence.

Size range(mm):

Out diameter:10-324mm
Wall Tickness:1-30mm
Length:14000mm max

It is a seamless carbon and alloy steel mechanical tube used in a wide range of industrial applications where mechanical properties and durability are crucial. This remarkable pipe standard, defined by the American Society for Testing and Materials (ASTM), ensures that industries across the board can access high-quality, reliable tubing.

The steel used in the mechanical tubing may be cast in ingots or may be strand cast. When steel of different grades is sequentially strand cast, identification of the resultant transition material is required. The seamless tubing is a tubular product made without a welded seam. It is usually manufactured by hot working steel, and if necessary, by subsequently cold finishing the hot-worked tubular product to produce the desired shape, dimensions and properties.

The tubes shall be furnished in the following shapes: round, square, rectangular and special sections. Heat analysis shall be made to determine the percentages of the elements specified. If secondary melting processes are used, the heat analysis shall be obtained from one remelted ingot or the product of one remelted ingot of each primary melt. The tubing shall be coated with a film of oil before shaping to retard rust when specified This abstract is a brief summary of the referenced standard. 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. 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.

Quality and Testing:

ASTM A519 steel pipes are subjected to rigorous quality control measures, ensuring that they meet the specified mechanical and dimensional requirements. Various tests, including hardness, tensile, and impact tests, are conducted to guarantee their reliability.

What is ASTM A519?

ASTM A519 covers several grades of carbon and alloy steel seamless mechanical tubing. The standard is also acceptable in the manufacture of piping. It is manufactured by hot working and then cold finishing the steel into round, square, rectangle or special shapes.

Scope

ASTM A519 specification covers several frades of carbon and alloy steel seamless mechanical tubing.

1.1 The frades anr listed in Tables 1, 2, and 3. When welding is used for joining the weldable mechanical tube grades, the welding procedure shall be suitable for the frade, the condition of the components, and the intended service.

1.2 This specification covers both seamless hot-finished emchanical tubing and seamless cold-finished mechanical tubing in sizes up to and including 12 3/4 in.(322.8mm) outside diameter of rround tubes with wall thicknesses as required.

1.3 The tubes shall be furnished in the following shapes, as specified by the purchaser:round, square, rectagular, and special sections.

1.4 Supplementary requirements of an optional nature are provided and when desired shall be so stated in the order.
