Specification covers for ASTM A519 seamless carbon steel tubing

TICO ASTM A519 seamless carbon steel tubing

ASTM A519 is a hollow section steel without surrounding seams, which is largely used for conveying fluid. This specification covers for several grades of carbon and alloy steel mechanical tubing, either hot-finished or cold-finished. According to the different shape of cross sectional, steel pipe can be divided into the round pipe and irregular tube. Under the conditions of the equal circumference, round pipe is the largest area and it can transport more fluid. In addition, when the circular cross section is subjected to internal or external radial pressure, the force is uniform. Therefore, the most steel pipe is round tube. Seamless steel tube is a tubular product without welded seams, which is usually manufactured by hot working steel. If necessary, the shape, size and performance of the tube are produced by subsequently cold finishing the hot-worked tubular product.

The ASTM A519 seamless carbon steel tube shall be furnished in the following shapes: round, square, rectangular and special sections. Percentage of elements can be determined by heat analysis. 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. A layer of O type membrane should be coated before tubing shaping to slow down the rust.

The following tips are reasons why our products are popular in home and abroad.

• Strict quality control
  From raw material to finished product, TICO ASTM A519 seamless pipes adopt the most advanced equipment under an integrated system and every process of production is under strict quality control.
• Pleasing surface finish
  The surface finish of TICO ASTM A519 seamless steel tube exactly meets customer requirements, which also meets the expected application specifications. Inherently excellent properties, adding the further improved heat treatment technology, thus obtain a pleasing surface texture.
• High dimensional accuracy
  In order to meet the strict standard of size precision, TICO tubular products especially focus on the production and detection of ASTM A519 dimensional tolerances. Excellent dimensional accuracy is the result of such efforts.
• Stable mechanical properties
  TICO tubular products make sure that products deliver exhibit consistent, uniform strength, work-ability and durability.
• Wide size availability
  Steel pipe and tubes are produced to a broad variety of specifications and in a wide range of sizes. TICO ASTM A519 seamless carbon steel tubing for such applications are available in what may be just about the widest ranges of types and sizes anywhere.
