Metal Bellows advanced technology

Prestressed corrugated metal pipe is galvanized (hot dip or cold plating) or galvanized (black belt) made of low-carbon steel by spiral folded seams, and for post-tensioned concrete structure in the prepared hole metal pipe. The tube structure is simple, easy indoor and outdoor construction site work, and the permeability, high pressure, strength, flexibility, to ensure construction quality. Culverts antiseptic spray corrugated steel pipe 1, grain pipe (board) is a thin-walled, corrugated tube shell lateral parts. It is both elastic properties have sealing properties, in force and torque for wave energy generated by the following axial, angular, lateral, and a good combination of displacement, sealing performance. 2, material: SS400 or Q235 hot rolled steel sheet; 3, material thickness: 2.0-2.7mm 4, according to the assembly in the form of classification: self-contained type, assembled type; 5, according to the import and export in the form of classification: orthogonal, oblique, straight mouth 7. The pipe joint connection in the form of classification; round, oval, arched, horseshoe-shaped, loop-shaped, pear-shaped, etc.:: inner flange and outer flange connections; oblique mouth 6, according to the channel cross section shape classification plates overlap, card Zhou connections. 8, diameter (span): 0.5-12m; 9, filling height: 0.5-60m; 10, ripple parameters: Macro (P) wave depth (D) (mm) 125 * 25,150 * 50,150 * 65,200 * 55,300 * 110,400 * 18,011, corrosion treatment: Hot-dip galvanizing> 63um; secondary preservative (usually by coating asphalt); 12, life:> 100 years. Practice has proved that, instead of using corrugated metal pipe culvert reinforced concrete culvert construction, in terms of the construction period, the construction cost and environmental significance and other aspects of its incomparable superiority, and with corrugated metal pipe culverts were culvert construction, can greatly improve the road driving comfort and safety, avoid road culvert "dislocation jumping" borrow conducive to resolving the issue northwest cold frost damage to concrete pipe culvert. http://www.sj77.cn/ http://www.kegujinshu.com/ http://www.guizi1.com/ http://www.guizi123.com/
