Carbon Steel Seamless Pipe




Steel India Co. is a manufacturer and supplier of Carbon Steel Pipes products for various uses. The carbon steel comprises of carbon and iron for the most part. Trace amounts of silicon, manganese and copper are allowed in different quantities depending on the grades. The Carbon Steel Seamless Pipes material therefore is stronger and is highly stress resistant. These properties make the pipes be applicable in heavy duty services. There are different methods and types of productions. The Carbon Steel Welded Pipes is produce through welding of lengthy sheets into pipess.

There is also the electric resistant welded Carbon Steel ERW Pipes which adds to the strength. There are different mechanical properties such as the pressure containment, which is governed by the schedules of the pipes. The Sch 40 Seamless Carbon Steel Pipes is made up of carbon and is seamless with less absolute roughness and has a schedule of 40. This means the pipes could be used with ease for installation, it is a medium range pressure rating and it is smooth. There are different polishes and finishes in the pipes as well. The Carbon Steel Black Pipes has no coating or finish. The High Carbon Steel cement lined pipes can be used to cover against corrosion. In some cases, low carbon versions such as the Low Carbon casing pipes are used to fight against corrosion to a certain level. Depending on the application requirement, we can supply you the right product. Please contact us with your inquiries.
