Seamless Pipe Applications
Steel pipes are categorized into seamless steel pipes and welded steel pipes based on production technology. Seamless steel tubes are manufactured through hot rolled and cold drawn processes, with hot rolled pipes offering superior strength compared to cold drawn tubes.
Common applications include:
- Steam pipelines
- Gas pipelines
- Liquefied gas pipelines
- Natural gas pipelines
- Petroleum product pipelines
- Various other gas and liquid transmission pipelines
