FAQ

Buyer Questions

Do you supply threaded pipes?

Yes, threading (BSPT/NPT) and grooved ends can be done locally before loading. Give us the end-connection type in your inquiry list.

Is the inside of the pipe galvanized too?

Hot-dip galvanized pipe is coated inside and outside. Pre-galvanized (zinc-coated strip) pipe is coated outside only — we will state clearly which type you are buying.
