AISI 904L Pipe Spools
SS 904L Pipe Spools are pre-welded flanged end pipes or fittings; ready for bolting and reducing the overall time frame for piping installation. 904L SS spools are fabricated using prime seamless or welded pipes welded with forged or plate machined flanges. 904L stainless steel spools are available from 3/8” NPS thru 24” NPS with different pressure class rated flanges.
Anand Steels is a manufacturer and supplier of SS 904L pipe and fittings spools; produced, tested and certified as required. We offer worldwide shipping by Sea or Air freight options.
