DIN is a German institute for the standardization of various types of equipment in the piping system. The din 2448 grade is produced following all standards set by ASME, ASTM AISI, DIN, EN, GB, IS, and JIS. The pipes and tubes of this grade can be seamless, welded, fabricated, ERW, EFW, U bent, hollow, etc.
DIN 2448 pipe can be seamless, welded, ERW, EFW, fabricated, U bent, hollow or hydraulic in production type. The din 2448 st35 pipes range in dimensions according to the standards. The outer diameter of the welded pipes ranges from 5mm to 1219.2mm. The same dimensions apply for EFW pipes as well.
Replaced by EN 10210, the DIN 2448 Seamless Steel Tubes could be hot formed either with or minus the consequent heat treatment. Or these hollow pipes could be cold formed with the use of a subsequent heat treatment process in order to achieve metallurgical conditions equivalent to those components as those seen amongst hot formed products.
The DIN 2448 standard sets various specifications for manufacturing these pipes and tubes. This includes dimensions, conventional masses per unit length, and couplings in addition to weights. A din 2448 pipe is designed with superior strength and excellent mechanical properties. These pipes show high resistance against reducing acids and all forms of corrosion.
DIN 2448 Seamless Steel tubes
The form of both DIN 2448 Seamless and welded steel pipes could be either rectangle, square, elliptical or circular, depending on the order placed by the manufacturer. One of the materials used to produce pipes according to this standard is ST52. This material is a low alloy structural steel grade, which exhibits high strength. The material used to make Din 2448 ST52.3 steel pipe could be easily welded to other grades of weldable steel. Grades that have a capital letter S in their designation such as in DIN 2448 ST 52 Pipe, are considered to be well suited for applications involving structural applications. To improve the corrosion resistance property of the material, a buyer can choose to order a zinc galvanized version of ASME B36.1M Din 2448 seamless hot rolled steel tubes. A thick layer of zinc protects the material from atmospheric corrosion. The manufacturer is permitted to remove surface defects by the use of a grinding process. However, the thickness of the DIN 2448 EN 10210 Steel Pipe must not be lesser than the minimum allowable thickness keeping in accordance to standard EN 10210-2.
