Precision Welded pipes

Cold drawn pipe tend to generate distortion, that is because the fitting is relatively thin, loading by extrusion was part of the deformation, then add cold drawn pipe in the shaking of the whole transport process, the led to the secondary damage, cause pipe squeezed flat.
It is not hard to see, resulting in cold drawn pipe squeezed in by the sake of Precision Welded pipes removing the destruction of human factors, mostly because of the loading of thick sequence distribution is not reliable, and the transport problems caused by, sometimes continue due to driver's bandage mediation tied the rope The reason caused. To manipulate a similar problem produce, must learn how to set the cold drawn pipe loading, all under normal conditions, the thick specifications shall first wall thickness on the bottom first, and in the middle of the mat under the block avoid shipping, metal material and metal material Material impact concentricity between the worse. To put cold drawing of thick wall tube in the above or in addition to put a region; And pick wood bound in the case of loading transport, in case to transport midway shaking and bending to raw materials. In addition, the rope tied Cases will be relatively compact, prevent lead to pipe damage, reduce unnecessary damage.
Cold rolled precision tube production and processing pipe generating set manufacturing feature is expected from the money into the production processed into finished products typically several times after cold deformation and cause cold work hardening, so all prepared ahead of time by several technological process and processing Change process, and having the features of reciprocating cycle system, so the process flow, production time is long, cost a lot of metal material, low productivity, high precision, both inside and outside surface bright and clean, no peeling, no crack, no pockmark.
Cold drawn pipe product features high precision cold drawn pipe tolerance size, product accuracy control + / - 0.05 mm; Good brightness; Inside and outside surface oxide layer, inner surface cleanliness. Cold drawn pipe comprehensive performance is good, can bear high pressure, cold bending, flaring, flattening is not craze,Not wrinkled skin, can do all kinds of complex deformation and mechanical processing. Application of stainless steel 304 pipes cold drawn pipe steel can be saved and improve processing efficiency, reduce machining process and equipment investment, can save cost and save machining time, greatly increased output and Material utilization, at the same time to improve product quality, reduce the cost.
Cold rolling process are: the basis of precision steel tube pipe materials, commonly used pipe materials for hot-rolled seamless steel tube manufactured goods or finishing pipe semi-finished products processing, extrusion tube and Precision steel tubes welded steel pipe; Pipe material are prepared ahead of time, including inspection, baling, pickling passivation, cleaning,in cleaning, drying, lubricants, etc.Cold drawn (cold and cold drawn); Manufactured goods manufactured goods conditioning with cast-rolling, straightening, sampling, cutting fore and aft, inspection (artificial service regularly check all sorts of flaw detection), suppression test, anointed with oil, packaging And into the library, etc.
