Hongrun's thick-walled large diameter pipes are our core competency production. These pipes are applied to equipment of thermal power plants which are more than 300MW, nuclear power, petroleum, chemical industry and connecting pipelines, etc.

The high forging ratio makes grains realigned to attain excellent strength. Well-type heat treatment furnace by precisely controlled parameter can achieve material mechanical properties as per customer’s requirement. Final machining provides required pipe geometry and size. The process used for making  seamless pipe soaking, punching, drawing and finally machining are the major processing steps.
