Spiral Steel silo development over 100 years of history, from the riveting style warehouse, welding positions, prefabricated warehouses and Anyang Lipp Silo Engineering Co., Ltd. of West Germany (also fame Pu warehouse or spiral warehouse) onwards, until now WDCPO steel warehouse patented technology advocacy group technical points warehouses, steel silo development of more than 100 years of history, the first widely used in foreign countries, steel grain storage silos origin applied in the early 1900s, the late 1970s, in foreign food industry, steel silo replace almost any type of granary. Currently, the U.S. uses 95% of the barn silo. Our steel silo technology application and development in the food industry started late. 1982, Heilongjiang Province, Honghe Farm introduce galvanized corrugated sheets fabricated steel silo from the United States, is the emergence of the first modern steel silo base. 1980s, China's steel silo construction has achieved unprecedented development. Heilongjiang Province, the introduction of absorption Yingchun Machinery Factory fabricated steel silo full range of American technology, special equipment production lines, according to the foreign advanced technology, design software, production standards, in the digestion and absorption basis, the innovation and development, began mass production, production and installation of fabricated steel silo, the strength, performance, security steel silo has the reliability and steel silo as a large number of export products, it represents China today silo production, production, installation of international level, is steel silo production leader installed. Currently, steel silo to store granular, powder, grain, food, brewing, coal, building materials, industrial and agricultural areas, urban and environmental industries and other fields are widely used.

Fabricated steel silo production profile

CNOOC Bilu Nan Tong pier steel silo project

A steel tube assemblies fabricated steel silo short positions (Figure 2.1, Figure 2.2), it is the mechanical roll and molded into corrugated sheet metal punching, the electric torque wrench connected by high strength bolts made ​​of positions. Assembly warehouse wall corrugated, sheet generally use galvanized sheet, its thickness is generally 0.8 ~ 4.2mm, the current warehouse wall thickness up to 8.4 mm. Corrugated siding method mostly used roll process, by mechanical molding production lines into mass production, automated production line can produce all kinds of corrugated board. Advantage of the roll method is successive wave shape, internal stress can be eliminated, small resilient, better quality plate production, even a little thicker plates can also be molded in a molding machine assembly line sequence. Also forming units and uncoiling machine, leveling machine, conveyor roller and hydraulic length flying shear and other equipment can be directly processed into the required specifications Coil corrugated steel products.

Philips type steel silo

Lipp type steel silo, also known as spiral steel silo, as the name suggests, there is a warehouse body roll machine Bengbu BBCA railway grain warehouse interim library

Group spiral made​​. Currently Lipp silo is made ​​with spiral coil occlusion warehouse unit, warehouse unit volume include: unwinding machines, crimping machines, machine, triangle gin pole, electrical control. The current volume warehouse unit SM30 and SM40 are mainly two kinds of specifications. SM30 for silo diameter range: 3 to 8 meters, SM40 for silo diameters ranging from 6 to 18 m.
