SAW pipes and ERW pipes are interchangable but SAW pipes have a higher diamater as compared to ERW pipes. ERW can be manufactured upto 24'' but SAW upto 100'' OD and are used for transportation of large amount of liquids. ERW are welded only longitudnally while saw pipes can be welded both longitudnally and spiral welded.

To manufacture seamless pipes in india the technology used are as follows

1. CPE technology - upto 7''OD
2. Plug mill technology - from 7'' OD to 14'' OD
3. High frequency induction welding for ERW pipes upto 21''OD
