ASTM A519, ASTM A519 Steel Pipe, Seamless steel pipes

ASTM A519 specification covers for several grades of carbon and alloy steel mechanical tubing, either hot-finished or cold-finished. 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

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.

【H】 Ceramic lined pipe

Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.

【H】 Cast basalt lined steel pipe

Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.

【H】 Ceramic Tile Lined Pipes

Ceramic tile lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe.

【H】 Rare earth alloy wear-resistant pipe

The material of the rare earth alloy wear-resistant pipe is ZG40CrMnMoNiSiRe, which is also the grade of rare earth alloy steel.

【H】 Tubes Erosion Shields

Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life.

【H】 ASTM A213 T91 Alloy Tube

The ASTM A213 T91 seamless tubes are primarily used for boiler, superheater, and heat-exchanger.
