Our range of Carbon steel welded pipes are widely acclaimed for their features such as high tensile strength, smooth internal finish and hardness. Designed with precision, these pipes are ideal for boilers, automobiles, ship building, nuclear power, transportation, petroleum plants and construction, the special specifications welded pipes can be processed according to user requirements. These Carbon steel welded pipes are generally developed for energy-related applications involving oil and gas drilling. Further, our range of Carbon steel welded pipes can be availed in different material and dimensional specifications as per specific application .

 

According to different welding methods the Carbon steel welded pipes can be divided into Electric arc welding pipes, the High frequency or Low frequency Electric Resistance Welded pipes ( ERW ), Longitudinal Submerged- Arc Welded pipes ( LSAW ) and Spiral Submerged- Arc Welded pipes ( SSAW ) etc.  

 

The Carbon steel welded pipes are mainly used for conveying water, sewage, gas, air, heating, steam , low-pressure fluid and other uses.
