Description

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

Testing & Inspection

  • Tensile test
  • Flattening test
  • Drift expanding test
  • Dimensional inspection
  • Roughness measurement
  • Visual examination
  • Non-destructive testing
  • Leak-tightness testing

Competitive Advantages

  • High-quality raw material source
  • Prompt delivery according to purchase order and agreement
  • Strict compliance with EN10305-2 standards and customer specifications
  • Experienced export team with response within 24 hours
