Product Description
TORICH Carbon Steel Cold Drawn Welded Tube Precision Steel Pipe DOM Steel Tube
welded tube italy
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 .
Production Process:
Cold rolling by Cold pilger machine and Cold rolling machine
Size: 6-350mm
WT: 1.0-35mm
1. Standard:
EN10305-2 Cold Drawn Precision Seamless Steel Pipes
2. Steel Grade:
E155,E195,E235,E275,E355, other materials upon agreement with customers.

| a. Rm: tensile strength ; ReH: upper yield strength (but see 11.1); A: elongation. For symbols for the delivery condition see Table 1. | |||||||||||||
| b. 1 Mpa = 1 N/mm2 | |||||||||||||
| c. Depending on the degree of cold work in the finishing pass the yield strength may nearly be as high as the tensile strengths. 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 relations is recommended: ReH ≥0.5 Rm | |||||||||||||
| e. For tubes with outside diameter ≤ 30 mm and wall thickness≤ 3mm, the ReH minimum values are 10 Mpa lower than the values given in this Table. | |||||||||||||
3. Production method:
Cold drawn on the welded steel tubes, to reach high accuracy on the OD and WT tolerance
4. Packing:
In Hexagonal Bundles, with anti-rust oil protection, with seaworthy packing
5. Deliver condition:
1). +C No heat treatment after the final cold drawing process
2). +LC After the final heat treatment there is a suitable drawing pass
3). +SR After the final cold drawing process there is a stress relieve heat treatment in a controlled atmosphere
4). +A After the final cold drawing process the tubes are annealed in a controlled atmosphere
5). +N After the final cold drawing operation the tubes are normalized in a controlled atmosphere
