To buy ASTM A519 seamless steel pipes means to purchase products made according to the standard applicable to a number of grades of mechanical pipes made of carbon or alloy steel, by hot rolling or cold deformation. In addition to round, products can have a square, rectangular or other special section.
Special properties
It is possible to order steel pipes in Ukraine, the production of which is regulated by the ASTM A519 standard, with an outer diameter of 10 to 324 millimeters, with a wall thickness of 1 to 30 millimeters.
In addition to high resistance to high pressure and significant temperatures, products of different brands are characterized by:
– minimum tensile strength from 331 to 855 megapascals;
– minimum strength according to Brinell 55 to 100 HB;
– minimum yield strength from 331 to 855 megapascals.
The price of ASTM A519 seamless steel pipes is slightly higher than that of seam products. But this is fully compensated by their high performance.
Areas of use
Products with different types of profile are widely used:
– in the construction industry;
– in mechanical engineering;
– for the formation of pipelines and gas pipelines.
