Tubular Steel Structure Cast Steel Node

Tubular Steel Structure Cast Steel Node    Product Description High strength cast steel nodes are often used in drilling rigs, offshore oil and gas projects, wind turbine foundations, the arch supports of large bridges, pipe racks in civil constructions and any other connections between large tubes.     Technical Parameter Great Wall node castings can exceed 3 meters in diameter and weigh over 100 tones. Special alloys offer ideal strength, toughness and weld ability. We work to tolerances of under ±1.5mm, which are at the physical limits of what can be achieved with castings of this size. Dimensions are verifiable by detailed 3D analysis of the finished piece.     Our Services We have full set of quality control system to guarantee best product quality. Depends on the products, we make different item testing plan, different manufacturing procedure and provide certified lab mechanical testing.     Company Information The factory covers an area of 50 acres,the total factory building area is 23800 m2 and model area is 9600m2.
