(Total 12 Products for Steel Casting Bend)
Seamless elbow: elbow is a kind of pipe fitting used for turning of pipe. In the pipeline system used in all the pipe fittings, the largest proportion, about 80%. In general, different forming processes are selected for different materials or wall thicknesses. At present, the factory used seamless elbow forming...
Production process Welding elbow production process, if the long radius of the elbow, you must first select specifications, put forward the tube material. Spread ratio, through theoretical calculation, the general expansion rate of 35% - 33%, and push back. Short radius 219mm general expanding diameter rate of 50%....
Stamping elbow points cold stamping and hot stamping two kinds, usually based on the properties of materials and equipment selection of cold stamping or hot stamping.Cold extrusion bend forming process is the use of special elbow forming machine, tube into the outer mold, mold clamping, under the push of tube billet...
Products have special requirements are still in use. The stamping of the elbow is formed by using the tube blank equal to the outside diameter of the elbow.Before stamping, the tube blank is placed on the lower die, and the inner core and the end mould are filled in the tube blank, and the upper die downward movement...
Stamping elbow is the earliest application in mass production, the forming process of seamless elbow, at present, in the production of the elbow of the commonly used specifications has been hot pushingpipe method or other forming techniques of alternative, but in some specifications of elbow due to less number of...
Steel metal bending pipe fittings
Compared with the hot pushing process, stamping the appearance quality is inferior to the former; stamping elbow in the forming of arc in tension and other parts of excess metal is not the compensation, so outside the arc wall thickness reduction thin about 10%. However, due to the characteristics of the single piece...
The stamping die due to ensure the stamping part dimension and shape precision, and generally does not destroy the stamping parts of the surface quality, and die life is generally longer, so stamping quality stability and interchangeability good, has the characteristic of "identical". The advantages of the forming...
Steel pressed pipe bend fitting
The forming process of stamping elbow is complicated, and it needs to be welded according to different materials and uses, and is gradually formed under certain pressure. Stamping elbow molding need according to a certain process, strictly comply with the corresponding process, otherwise the production of stamping...
Steel pressed pipes bends fitting
The stamping generally without cutting scrap generated, material consumption is less, and does not need to other heating equipment, so it is a kind of material saving, energy saving and processing, stamping parts of the cost is low. The stamping process the size range is larger, more complex shape parts, such as a...
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...
Jet Hydraulic Pipes are useful for moving seabed soils for the burial of cables and pipelines and for installing instrument tubes and structural piles. Jetting is done by supplying pressurized water from a pump mounted on a surface-support platform. A variety of jetting mandrels and nozzles can be used, depending on...
The jet bend pipe is also called submerged arc welding spiral steel pipe. The main function is mainly used to clean the steel pipe conveying sediment, mud and other mixed debris. Aims: excavated harbor basin and approach channel, land reclamation epeirogenic to the construction of wharf, port and port-vicinity...
