API 5L X70 Pipe

We are making carbon steel seamless pipes and stainless steel welded pipes in quality material which are durable in use and long lasting. These steel pipes are fruitfully supporting and playing the main part in the pipe fittings where liquid flow is made possible and effective.

API 5L X70 Pipe


We have advanced production line where we are producing various types and categories of carbon steel seamless and stainless steel products for general and commercial uses.
