The steel pipe pressed bend is used to change the direction of run of pipe.Its advantage is can matach long distance transition requirements,so it is commonly that bends dimension according to customer design. usually,the bends consist of 3D,5D,7D even 12D series.A bend is simply a generic term in piping for an...
A spud barge, or jack up barge is a type of vessel which is capable of providing a solid work platform in offshore, inland and coastal construction operations. Each [spud" consists of a heavy-duty pipe or other fabricated cylindrical object, which is driven into the sea floor or river bottom for increased stability...
Dredger is a kind of high science and technology ship,and spud is the major structural part and throw away unit in the dredger.The design of spud is the key to design the dredger because of its complex force and high breakage rate. The spud is the most vulnerable structural member of the dredger, and the end of the...
