Welded Steel Pipe
EN 10210 Steel Pipe
EN 10210 is a european standard prepared for structural steel.
There are various grades that come under this standard like S235, S275, S355, S420, and S460. out of these, the commonly used grade is EN 10210 S355 grade.
This part of this european standard specifies technical delivery conditions for hot finished hollow sections of circular, square, rectangular or elliptical forms and applies to hollow sections formed hot, with or without subsequent heat treatment, or formed cold with subsequent heat treatment to obtain equivalent metallurgical conditions to those obtained in the hot formed product.
Out Diameter: 219-1422 mm ( 8"-56"), tolerance: ±1%
Wall Thickness: 9.53-140mm
Length: 6-11.8Meter
Surface: bare, black varnish or light oiled
Pipe End: Plain or Beveled (Can be Protected By Plastic Pipe Cap)
NDE: UT, ET or Hydraulic testing
Straightness: WT＜30mm, not more than 2mm per meter, WT≥30mm, not more than 3mm per meter
Others: According EN10210 standard

A. The deoxidation methods are designated as follows: FN = Rimming steel not permitted
FF = Fully killed steel containing nitrogen binding elements in amounts sufficient to bind available nitrogen
(e.g. min. 0,020 % total Al, or 0,015 % soluble Al).
B. It is permissible to exceed the specified values provided that for each increase of 0,001 % N the P max. content is also reduced by 0,005 %. The N content of the cast analysis, however, shall not be more than 0,012 %.
C. The maximum value for nitrogen does not apply if the chemical composition shows a minimum total Al content of 0,020 % with a
