Expanded shells due to a visual form such as Turtle, hence the name. Has been called the shells are usually stretched network, or simply shells network. Net shape tensile steel is the most beautiful products. 

 Expanded shells specifications: pitch 2cm-6cm; net thickness of 1cm-2.5cm; Thickness 1mm-3mm. There are special requirements can be processed to order. 

 Expanded shells material: carbon steel, high temperature, corrosion-resistant special metals. 

 Steel shells network characteristics: network is a high temperature metal shells, special corrosion-resistant metal, stamping equipment assembled by a professional three-dimensional hexagonal network of interconnected hexagonal holes are easy to bend arc, welding in the shell After the wall, poured refractory aggregate, increase the service life several times, and refractory materials will not peel off, long service life. Generally used for wear-resistant material lining to enhance the capacity of the anchor with the lining material. 

 Steel shells are widely used in petrochemical large network installations, especially in favor of the catalyst of the device structure of the main equipment lining one of the major components, which can improve the lining of the wear resistance and strength, wear-resistant linings are used shells network reinforcement, general parts of carbon steel (A3F) shells network, such as the reactor and a secondary cyclone, U-tube regenerator flue, etc., high-temperature parts of the alloy (1Cr13) shells network, such as the regenerator and one, two cyclone, etc.. Shells network of 20 * 17.5 mm flat punch into a hexagonal lattice with fixed screw terminal board in the insulation. Also be used for construction, roads, bridges, steel bars used for
