Seamless Hot Rolled Steel Pipe , Carbon Steel Pipe Wall Thickness
18'' 457mm OD
Each one of our steel tubes is made of quality carbon steel through
a process known as hot rolling. We can build our hot rolled
seamless steel pipes in a variety of standards, including DIN, JID,
ASME and EN.
Not only do our carbon steel pipes have excellent chemical and
physical properties, but they are put through hydrostatic tests,
flanged, flattened, and expanded at both ends to check if the
strength, elasticity, and pressure resistance meet industry
standards.
1. Standards
ASME SA106 —— American Boiler and Pressure Vessel norms
ASME SA333 —— American Boiler and Pressure Vessel norms
ASME SA335 —— American Boiler and Pressure Vessel norms
DIN17175 —— German industry standards
EN10216-2 —— European pressure piping standards
2. Application
For the low and medium pressure boiler and steam header pipes; for
the high-pressure boiler and steam pipes, and the petrochemical
industry pipes.
