Carbon steel pipes for ordinary piping are used widely, including in piping for steam, water, oil, gas, air and more.
Applications and Features
Our carbon steel pipes for ordinary piping are manufactured using electric resistance welding and are either black or galvanized.
These pipes can be used in piping for steam under relatively low pressure, water (excluding public water supply), oil, gas, air, and more.
Grooving corrosion-resistant electric resistance welded steel pipes (Super Seams) are needed for piping where corrosion is a concern. Contact us for details.
Chemical Composition and Mechanical Properties
- The No. 12 and No. 5 test pieces are taken form portions that do not include seams.
- Specifications do not apply regarding the elongation of tubes with a nominal diameter of 32A or less; they are only for record purposes. However, elongations may be stipulated on agreement between the receiving and delivering parties.
- The minimum elongation value when conducting the tensile test using the No. 12 test piece (tube axis direction) or the No. 5 test piece (tube radial direction) differs depending on the wall thickness classification.
D: Outer diameter of tube (mm)
Standard Dimensions / Mass and Dimensional Tolerances
The standard length of one pipe is 5,500 mm.
