GB 50566-2010Code for installation and quality acceptance of metallurgical dedusting equipment (English PDF)

1.0.1

This Code is formulated with view to regulating the installation of metallurgical dedusting machinery and equipment engineering, unifying the construction quality acceptance criteria and safeguarding the engineering installation quality.

1.0.2

This Code is applicable to the installation and quality acceptance of dedusting machinery and equipment engineering in the coking plant, refractory plant, sintered plant, ironworks, steelworks, continuous casting plant, rolling plant and power plant in the metallurgical engineering construction.

1.0.3

The variety, specification and performance of raw materials, semi-finished products and finished products used for installation engineering of metallurgical dedusting machinery and equipment must comply with the relevant current standards of the nation, and it is strictly prohibited to use the products explicitly ordered by the State to be eliminated.

1.0.4

The installation and quality acceptance of metallurgical dedusting machinery and equipment shall not only meet this Code but also comply with those in the current relevant ones of the nation.
