Frequently Asked Questions

Do you deliver outside Maharashtra?

Yes, we supply to industrial buyers across India from our Mumbai/Thane base.

Which standards do you supply against?

We supply against ASTM, ASME, API and IS standards depending on the product and grade required. Please share your specification and we will confirm availability.

What is the difference between seamless and ERW pipe?

Seamless pipe is manufactured without a weld seam, generally offering higher pressure ratings, while ERW (welded) pipe is manufactured by rolling and electric-resistance welding, and is typically more economical for lower-pressure applications.
