PT Special Metals Indonesia supplies Titanium, Nickel Alloys and exotic metal flanges in sizes ranging from 1/2” to 24”. All flat face flanges are supplied with serrated spiral finish per ASME/ASTM B16.5. “Alloy pipe flanges” is catch-all term we use to refer material grades which are not as carbon or stainless. Most nickel alloy varieties will fall under this category (Titanium, Hastelloy, Inconel, Monel, Incoloy, etc)
Alloy name, UNS Number and flange type are the three requirements for manufacture of flanges and forged items to industry standards such as ASME B16.5 or non-standard dimensions as per end-user requirements. These alloys are primarily selected for use in high temperature and/or corrosive environments. We understand that special metal flanges are used in critical applications which need to withstand corrosive, harsh environment for many years.
Incoloy® alloys 800H and 800HT are utilized in high temperature services where resistance to creep and rupture is required.
