Roundness diameter pipe should not exceed 1% of the respective ends of the diameter, and the tolerance of ± 3mm. Diameter pipe material execution SY/T5037, GB/T9711, GB/T8163, American Standard ASTM A106/A53 GRB, API 5L, APT5CT, ASTM A105, ASTM A234, ASTM A106, DIN German standards and customer requirements standard diameter pipe (size of the head) for a pipe at the pipe reducers. Forming process commonly used to necking repression, expanding repression or suppression of necking plus expanding on some of the specifications of the reducers may also be stamping. Necking / expanding forming necking diameter pipe forming process is the big end diameter pipe with a diameter equal to the tube into the mold, the tube axial direction through the suppression of concentric, eccentric reducer manufacturer the metal movement and contraction along the cavity forming. Depending on the size diameter pipe reducers, divided into one or more press-forming press forming. Concentric reducer reduced diameter forming forming is a schematic diagram of expanding the use of less than the diameter of the big end of the tube diameter pipe with an inner diameter of the die along the tube flaring forming. Expanding process is mainly to solve the larger diameter pipe reducer difficult situation by forming necking, and sometimes need to materials and products shaping the expanding and necking methods combined. In necking deformation or expanding the pressing process diameter pipe, adjustable according to different materials and conditions, determine the use of cold or hot. Typically, as far as possible cold, but many adjustable cause severe hardening in the case, the case of the wall thickness or partial thickness of the alloy material is preferably a hot press. Stamping steel as raw materials in addition to the use of outside diameter pipe, tube diameter on the part of the specifications can be adopted with steel stamping process for production. Stretching die shape inside diameter pipe used in reference to the size of the design surface, with the steel stamping die cutting after stretch forming. Concentric Reducer Description: concentric reducer manufacturing process easiest, with wall thickness of the tube as thick rough, expanding one end with an equal diameter or thickness of the tube as a rough, narrow end of the bore can be. Either flared or necking, is generally used to suppress mold. Current domestic commonly used to suppress progressive eccentric mold wholesale concentric eccentric reducer, eccentric reducer, eccentric reducer three or more carbon produced by this process concentric reducer prices, eccentric head end will produce serious gap from the inner wall of the tumor, uneven thickness and oval and so on. Press truncated truncated concentric reducer eccentric reducer instead of the resulting structure, oblique section because it is not a round face oval face, it will exist between the wrong end and straight edges, not completely phase problems. If a new pressing process, which is to suppress the mold with concentric concentric reducer, then pressed into a good concentric reducer eccentric mold is needed to suppress the integer eccentric reducer, its internal and external smooth surface, small head smooth, uniform thickness, roundness qualified, less raw materials used.
