EN10305-2 E215 E235 Welded Steel Pipe, Precision Cold Drawn Steel Pipe for Machinery
Description
EN10305-2 welded precision cold drawn steel tubes are manufactured from electric welded pre-tubes through cold drawing or other suitable processes. These tubes are designed for high-precision applications in the machinery and automotive sectors, offering excellent dimensional accuracy and surface quality. The absence of welds used for joining lengths of flat rolled strips prior to forming ensures superior structural integrity.
Size Range
Outside Diameter (O.D.): 10 – 89 mm
Wall Thickness (W.T.): 0.5 – 10 mm
Steel Grades
E195 (1.0034)
E235 (1.0308)
E275 (1.0225)
E355 (1.0580)
E215 (1.0212)
Manufacturing Process
ERW + DOM (Electric Resistance Welded + Drawn Over Mandrel)
Cold drawn from welded pre-tubes
No longitudinal weld seam joining prior to forming
Key Advantages
High concentricity and dimensional precision
Cost-effective alternative to seamless tubes
Consistent mechanical properties
Suitable for high-stress mechanical applications
