BOILER ERECTION • Column erection • Pressure part erection • Miscellaneous
COLUMN ERECTION • The boiler presently in use are hanging type. • The column are broken up during manufacture into several pieces and transported to site • Where it is pre assembled in two or three pieces and erected. • Utmost care is taken in the pre-assembly stage to maintain the matching of the of the column end faces and to achieve vertically well within the tolerance limit
COLUMN ERECTION
• Verticality is single most important factor and is given top priority • The maximum column verticality is 20mm. • Once the column erection is over up to the full height cross beams are placed securely over the column which supports the main boiler
COLUMN ERECTION
• In order to carry out this job special erection tool like cranes with extra long boom to carry heavy loads at that height are used. • After cross beam erection, entire structure structure is adequately braced to achieve sufficient strength.
