Hot Dip Galvanized Steel Pipes

HSL Hot Dip Galvanized (HDG) Steel Pipes & Tubes Manufactured by Harso Steels, are welded black steel tubes undergone the process of cleaning by the method of pickling and then dipped in boiling zinc bath under stringent controls in order to give an even Hot Dip Galvanised coating to both the external and internal surfaces with a minimum coating weight of 300g/m² making it applicable for use in various Domestic, Commercial & Industrial uses. HDG Steel Pipes & Tubes displays high corrosion resistance and is inert to various toxic and hazardous Fluids & Gases, for this reason it performs better under extreme conditions.

The standard end finish is a plain end. A variety of optional end finishes are available subject to enquiry. This includes roll grooved, shouldered and screwed on either one or both ends. Available as per IS 1239 / ASTM A53 / BS 1387

Persistent

Thru Perseverance

  • Hot Dip Galvanised finished products are perfect for jobs that require longer lasting protection against all weather and all conditions.
  • HDG is suitable for use in a wide range of pipe related applications.

Their main advantages are as follows:

  • Uniform distribution of steel around the circular provides for superior Mechanical resistance
  • Smooth surface of the Tube ensures no trappings of dirt and water, minimizing corrosion reaction possibilities.
  • Serves A leak-free Life of 15yrs.
  • Produced by Electric Resistance Welded (ERW) process
  • Fire resistance.
