Treating Iron (Pup Joints)
Treating Iron is a kind of pressure pipe with hammer union end connection and flange end connection. Treating Iron can be made integral or weld type which end connection is welded to pipe. Cost of Intergal type is higher than welded type.
Hammer union end connection is designed to interchangable with weco wing union, including Fig.100, Fig.206, Fig. 207, Fig. 602, Fig. 1002, Fig. 1502, Fig. 2002, Fig. 2202 and etc.
Flange end connection is designed according to API 6A or ASME standard.
Working pressure of pup joint is from 2,000 psi to 20,000psi.
Manufacturing theory is according to API 16C.
