Product Description
Reducing pipes, which are used to connect pipes of different diameters.
Reducer pipe refers to pipe fittings that connect pipe sections with different diameters in series in sequence. It is often used where there are multiple branch pipes along the way. The inlet ends of several single pipelines or series pipelines are gathered together, and the outlet ends are also connected to form a pipe network. It is used for pipeline projects with particularly large transmission volume or multiple expansions.
Because it is a closed loop connected by pipes of different diameters. It is mostly used in oil and gas gathering and transportation pipeline networks in oil and gas fields, urban water supply or gas distribution pipeline networks, etc. The conveying reliability is high. At each node of the pipe network, the outflow is equal to the inflow.
Reducer is generally divided into concentric reducer and eccentric reducer. When the projection of the two ports is concentric after the reducer is erected, it is called concentric reducer, and the projection of eccentric reducer It is a small circle that is tangent to the outer circle.
The materials of the reducer include stainless steel reducer, alloy steel reducer, reducer carbon steel, reducer 20 gauge steel, etc. The roundness of the reducer should not be greater than 1% of the outer diameter of the corresponding end, and the allowable deviation is ±3mm. The material of the reducer is in accordance with SY/T5037, GB/T9711, GB/T8163, American standard ASTMA106/A53GRB, API5L, APT5CT, ASTMA105, ASTMA234, ASTMA106, DIN German standard and customer requirements standard reducer (size head) is used A type of pipe fitting at the reduced diameter of the pipeline. The commonly used forming process is reducing diameter pressing, expanding diameter pressing or reducing diameter plus expanding diameter pressing, and stamping forming can also be used for reducing diameter pipes of certain specifications. The reducing forming process of reducing/expanding forming reducer is to put a tube blank with the same diameter as the large end of the reducer into a forming die, and press in the axial direction of the tube blank to make the metal move and move along the mold cavity. Shrink forming. According to the size of the reducing diameter of the reducer, it is divided into one-time press forming or multiple press forming. Diameter expansion forming is to use a tube blank smaller than the diameter of the large end of the reducing tube, and use an inner die to expand the diameter along the inner diameter of the tube blank. Diameter expansion technology mainly solves the problem that the diameter reducing pipe is not easy to be formed by reducing diameter. Sometimes according to the material and product forming needs, the method of expanding diameter and reducing diameter is combined and used. In the process of reduction or expansion deformation, cold pressing or hot pressing is determined according to different materials and diameter changes. Under normal circumstances, cold pressing should be used as much as possible, but hot pressing should be used for severe work hardening caused by multiple diameter changes, thicker walls or alloy steel materials. In addition to the use of steel pipes as raw materials for the production of reducing pipes, the stamping forming process can also be used to produce reducers of certain specifications using steel plate stamping forming processes. The shape of the punch used for drawing is designed with reference to the size of the inner surface of the reducer, and the blanked steel plate is punched and stretched by the punch.
The model range of various reducers of our company is Φ50mm-Φ2420mm.the pipe network, the outflow is equal to the inflow.
