boiler header spare part
Boiler Headers form an important part of all types of boilers.
Steam from the generating tubes is collected in headers which are
therefore always under pressure.The stubs of various sizes are very
carefully welded to the main body of the header to provide the
desired openings from the headers.
Natural gas industry Boiler Header can be made of alloy steel,
carbon steel or other kind of material as per the customer’s
requirements. It conforms to the standard of ASTM, EN, DIN, GB.
The manufacturing equipment is 30~185MN hydraulic press, the
forging ratio >3, the technical condition is in accordance with
the standard of ASTM, EN, DIN, GB.
