Headers collect and distribute steam or water from or to a series of smaller pipes or conduits. Manufactured from carbon or ferritic steel, these components typically match the grade of the connected piping systems. Unlike piping systems which are usually butt welded and bent, headers maintain a straight configuration.

The operational pressures and temperatures headers must withstand vary according to their connected components. Headers connected to economizers or water wall panels face less demanding material requirements than those connected to superheaters or reheaters.

Available in carbon steel to high-alloy ferritic steels (including T/P91 and T/P92), our headers accommodate diverse temperature and pressure needs, with sizes ranging from 88.9 mm to 406.4 mm.

Steam boiler pressure part headers with large diameter longitudinal welded pipes serve multiple functions including water wall headers, superheater headers, and economizer headers. These components perform critical roles in collecting, mixing, and redistributing working medium. Structurally, they are classified as either end cover type (end enclosure) or necking down type.
