Seamless Pipes


DHT provide a large variety Seamless Pipe. Ideal for long life service, we ensure our offered range is well tested on various parameters of quality before their final dispatch at clients end. These are offered to the customers in various specifications at industry leading prices.

Seamless (SMLS) pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. As the manufacturing process does not include any welding, seamless pipes are perceived to be stronger and more reliable. Historically seamless pipe was regarded as withstanding pressure better than other types, and was often more easily available than welded pipe.
