Description

A two-half press-butt-welded fitting for a large-scale pipeline with a straight pipe section with a small head and a variable diameter

technical field

The utility model relates to a large-scale pipe fitting with a straight pipe section with variable diameters, in particular to a two-half pressed butt-welded pipe fitting with a straight pipe section with variable diameters for a large pipeline.

Background technique

At present, when processing large-diameter pipes with diameters of 800mm-5000mm and large-diameter small-diameter pipes with straight pipe fittings, it is necessary to pass through multi-stage molds and multiple processes to complete the overall blank extrusion molding, and then through welding and grinding. The overall mold Production requires a large amount of materials, high cost, a large amount of energy is consumed in the process of processing, the operation is complicated, the processing is difficult, the quality and effect of the processed products are poor, and the processing cost of the enterprise is increased; in view of the above reasons, a large-scale Two-half press-butt-weld fittings for pipes with straight pipe sections with reduced diameters.

Utility model content

The purpose of this utility model is to overcome the existing large-diameter pipe diameter 800mm-5000mm large-caliber small-diameter pipe mouth with straight pipe pipe fittings processing, it is necessary to pass through multi-stage molds and multiple processes to complete the overall blank extrusion molding , and then through welding and grinding, the overall mold making needs to consume a lot of materials, high cost, a lot of energy in the process of processing, complex operation, difficult processing, poor quality and effect of processed products; through reasonable design, provide A kind of two-half pressed butt-welded pipe fittings with straight pipe sections with different diameters. The utility model adopts a set of semicircular molds, which can be divided into two processings. Two semicircular pipe fittings are processed twice and then combined together. It is welded, easy to operate, reduces the production of multiple sets of molds, does not need to repeatedly move workpieces and multi-level processing procedures, saves energy and reduces consumption, greatly reduces processing costs, and ensures stable processing quality.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a two-half pressed butt-welded pipe fitting with a straight pipe section with variable diameter, which is composed of: a first piece of pipe fitting, a second piece of pipe fitting, a small-mouth straight pipe, a large-mouth pipe Consists of straight pipes and variable diameter pipes; the first piece of pipe fittings and the second piece of pipe fittings are respectively provided with small-mouth straight pipes, variable-diameter pipes, and large-mouth straight pipes;

The pipe walls of the first piece of pipe fittings and the second piece of pipe fittings are set in accordance with the small-mouth straight pipes, variable-diameter pipes, and large-mouth straight pipes;

Weld seams are set between the wall seams of the small-mouth straight pipes, variable-diameter pipes, and large-mouth straight pipes of the first piece of pipe fittings and the second piece of pipe fittings.

Beneficial effects: the utility model adopts a set of semicircular molds, which can be divided into two processings. Two semicircular pipe fittings are processed twice, and then welded together. The operation is simple, and the production of multiple sets of molds is reduced without repetition. Moving workpieces and multi-level processing procedures save energy and reduce consumption, greatly reduce processing costs, and ensure stable processing quality.
