2.WHAT IS A519 STEEL?

This specification covers several grades of carbon and alloy steel seamless mechanical pipe. When welding is used for joining the weldable mechanical tube grades, the welding procedure shall be suitable for the grade, the condition of the components, and the intended service.

2.This specification covers both seamless hot-finished mechanical pipeand seamless cold-finished mechanical pipein sizes up to and including 12 3⁄4 in. (323.8 mm) outside diameter for round tubes with wall thicknesses as required.

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

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

3.Characteristic Features of ASTM A 519 Pipes:

Tubes under ASTM A 519 specification can be round, square, rectangular, or spiral, depending on the client's demands.
Any pipe claiming to be an ASTM A 519-grade pipe must meet the specification requirements. This entails top-notch finishing devoid of laps, cracks, seams, and other forms of a defect.
This specification offers standards for hot finished and cold finished seamless pipes with an Outside Diameter (OD) up to 12 3/4 inches.
The steel used under this specification may be cast from ingots or be strand cast.
The permissible variation in the squareness tolerance of square/ rectangular pipeis achieved using the formula +/-b = c X 0.006.
Square or rectangular pipeunder ASTM A 519 specs are allowed a variation of 0.060 within 3 feet of the pipe.
Clients can specify the tubes to be coated with rust-resisting oil before shaping. If they so wish, the product can retain this coating well till the shipping process.
The Wall Thickness (WT) of ASTM A 519 pipeis between 2mm to 120mm.
These pipes/tubes typically have a bevelled or a plain end.
Tests like non-destructive quality tests, flaring tests, hardness tests, and tension tests are some examinations conducted to check the tube quality. Aside from these, this piping is also checked for cleanliness and hardenability.
