    EN10305-2 E235 E355 Cold Drawn Welded Precision Steel Tubes DOM tube

     

    EN10305-2 Cold Drawn Welded Precision Steel Tubes DOM tubing E155,E195,E235,E275,E355 +C +LC +SR +A +N

    DOM is a process that is applied to tubing after it is initially constructed.It is refferred to as Seamless ,It can be said that do seamless process method on ERW tubes,So the tubes will have a high strength ,high quality .Material form E155 E195 E235 E275 E355 1020 1026 and so on .DOM tubing is commonly use in auto parts .

    aRm: tensile strength; ReH: upper yield strength; A: elongation after fracture
    b 1Mpa=1N/mm2
    c Depending on the degree of cold work in the finishing pass the yield strength may nearly be as high as the tensile strength.
    For calculation purposes the following relations are recommended:
    for delivery condition +C: ReH ≥0.8 Rm
    for delivery condition +LC: ReH ≥0.7 Rm
    d For calculation purposes the following relation is recommended:ReH≥0.5Rm

    Production Method:
    The cold drawn welded tube is produced by drawing ERW (electric resistance welded tube).During this process the sizing (wall thickness, inside and outside diameter), as well as weld integrity and surface finish is closely controlled to produce tube of the required size and mechanical property characteristics.

    Cold Drawn Precision Welded Steel Tube DOM Tube Stabilizer Automotive Parts
    Advantage (compare with seamless cold drawn tube)
    Better shape
    Improved quality surface
    Tight Excentricity and wall thickness tolerances (the eccentric
    Tube more safety
    Good toughness at low temperature
    USA Market: 90% of the cylinder in the USA market are produced with welded tubes
    Cost fix Lengths More Cheaper
