Painting and packing specification of boiler
1 Scope
This standard specifies the painting and packing specification of finished boiler products.
This standard is applicable to the painting and packing of boiler products and their accessories (spare parts). Any special requirements for the painting and packing of product shall be stated in the order contract.
This standard may also be served as a reference for the painting and packing of organic heat carrier boilers and other boiler products.

3.1 General
3.1.1 Painting and packing shall be carried out after the boiler products are manufactured and inspected as acceptable.
3.1.2 The painting of boiler products is divided into two types: the painting of boiler steel structure components and the painting of boiler general components (other than steel structure components).
3.1.3 The boiler steel structure components include steel frame (column, beam, roof, vertical support, horizontal support, etc.), rigid beam, platform, escalator, railing, roof frame, etc. Painting of structural parts such as steel structures in front of, behind and on the side of furnace, steel structures between coal bunkers, denitration steel structures, dust collector steel structures, desulfurization island steel structure, elevator shaft steel structure and hanging device can be carried out with reference to that of steel structure components.
3.1.4 The painting according to this standard shall be economical and beautiful, and can guarantee the surface protection of the product for 6 months. If longer surface protection is required, it shall be negotiated between the supplier and the purchaser.
