PUSHPAK ERW / CDW Precision Tubes are produced at our state- of- the- art manufacturing plant that has the capabilities to produce high quality tubes at low cost and with short lead times.


Our CDW Tubes are suitable for a wide variety of applications since they have several special characteristics such as:

PUSHPAK offering ERW/CDW Precision Tubes, which are widely used in making shock absorber, gas spring applications,
  • High precision dimensional tolerances.
  • Higher strength.
  • Controlled uniform mechanical properties.
  • Smooth surface finish - 0.2 Ra for cylinder bore quality.
  • Uniform sectional thickness.

Various steps in the manufacturing process accord our CDW tubes all the desired characteristics:
  • Annealing and Surface treatment of ERW tubes.
  • Cold swaging/push pointing operations for preparing pointed ends.
  • High precision close machined die to control outer diameter.
  • Plug placed coaxial with outer die to control inner diameter.
  • Annealing, straightening, 100 % eddy current testing ensure quality and fitness for required application.

    DIN 2391 St35 Pipes are low carbon steel pipes that are low cost and effective pipes. These are used in high pressure and high temperature services. Multi Metals (India) is a leading manufacturer and supplier of the DIN 2391 St35 Carbon Steel Seamless Pipes and other types of pipes in different grades, shapes and sizes. The material has carbon, silicon, manganese, phosphorus and sulfur.

    The DIN 2391 St 35 Nbk Seamless Tubes have 340MPa minimum yield strength and 470MPa minimum tensile strength. There are equivalent designations to the DIN 2391 St35 Gbk that can be used as well. These are used in applications that are dimensionally accurate and have smaller wall thicknesses. The applications of the
    St 35 Nbk DIN 2391 pipes are used in oil and gas, petrochemical, petroleum, oil refineries and other high heat and high pressure applications. The carbon steel pipes in general have high thermal conductivity and the DIN 2391 St35 High Precision Seamless Pipe can transfer heat very effectively.
