Ductile iron is in the 50 s of the 20th century developed a kind of high strength cast iron material, its comprehensive performance is close to steel, it is based on its superior performance, has been successfully used in casting
some complex loading, requiring higher strength, toughness and abrasion resistance parts.
Ductile cast iron has been developed rapidly for behind of gray cast iron, cast iron material application is very extensive.
The so-called & other;
In steel & iron generation throughout;
, mainly refers to nodular cast iron.
Small make up today about the ductile iron pipes to to tell you about the matters need attention during installation.
A, water supply and gas transmission pipeline project should be in accordance with the design documents and construction drawing construction, ductile cast iron pipes, pipe fittings should comply with the relevant products of the current national standard (
Or the international current standards (
Regulation, and shall have the factory certificate, for domestic and drinking water pipeline, the material shall not be polluted water quality.
Water supply and gas transmission pipeline engineering construction, should follow the national and local relevant laws and regulations, project acceptance shall comply with the relevant national standards and norms.
Second, water supply and gas transmission pipeline project before construction should have clarificaiton design unit design, and investigation and study, to meet the need of construction master along pipeline information and data of the following: 1, the site topography and landforms, buildings, all kinds of pipes and other facilities;
2, engineering materials, hydrogeological, engineering and construction of water, drainage, power supply condition, etc. ;
3, engineering materials, construction machinery supply conditions;
4, in the construction or the shore in the surface water, should master the surface water hydrology and shipping information;
When construction in cold region, should master the surface water of freezing and ice data;
5, combination with the engineering characteristics and site conditions of other information and materials.
Three, to drainage should prepare the drainage construction design, construction drainage drainage should be considered not affect traffic, does not destroy roads, farmland, Banks and other buildings of the issues involved, and a series of drainage structure.
That is about the ductile iron pipes the matters need attention when installation, today small make up to you at this point we see you next time.
