Difference between galvanized pipe and seamless pipe

Below are some of the difference between galvanized pipe and seamless pipe.

  • Galvanized pipe is usually electroplated by zinc to prevent rusting. Galvanized steel pipe is lighter than seamless steel pipe and this allows for use in places that require light steel pipes like the balcony, seamless pipes are a little heavy and therefore not suitable for use.

  • Seamless steel pipes are much more expensive than the galvanized steel pipe more because of the thickness of it's walls.

  • Galvanized steel is durable and with the excellent quality, it can be used for a very long period of time. To enhance corrosion resistance and prolong life, hot dip galvanized welded steel pipe is normally used.

  • Differences in applications: Seamless steel pipe is widely used in pipeline, except for water, gas, oil, general low pressure fluid line pipe, also used as heating oil oil industry in particular, marine oil field oil well pipes, pipelines, chemical coking equipment, a condensate cooler, coal distillation of wash oil exchange Used pipe, and trestle piles, mine tunnel support frame with a pipe. Galvanized pipe generally is utilized to make make fences, fence, fence, balcony guardrail. Commonly used in municipal projects, roads, factories, schools, development zones, gardens, squares, residential and other places.

  • Differences in the Manufacturing process: Galvanized steel is usually galvanized with zinc for the purposes of rust management.They may be welded pipe or at times seamless.Seamless steel pipe manufacturing process means they are welded and seamless thus seamless steel pipe.

Products Processing

The manufacturing process and testing of our high quality galvanized seamless steel pipe is standard and the process ensures for high quality finished product. The main testing process include the following;

  • Bend test

Ensures that no crack shall occur in any portion of the test piece and no opening of the weld shall occur.

  • Hydrostatic test

Pipe to withstand a hydrostatic test without leakage through the weld seam or the pipe body. Hydrostatic tested provide the pipe sections used were successfully tested.

  • Flattening test

Acceptance criteria for flattening test shall be:

The test allows for the pipes to have less openings and welded parts are up to the needed diameter and that the sizes and other properties are upto the standards of a full galvanized seamless steel pipe specification.
