Description
Technical Field
The invention belongs to the technical field of plastic pipeline manufacturing equipment, and particularly relates to a nonmetal composite pipe flaring device.
Background
In the field of oil fields, the scaling and waxing phenomena of oil pipelines are very serious, and the consistency of the overall drift diameter of the pipelines is required to be ensured in order to reduce the adhesion of the scaling at the joints of the pipelines. But because the nominal pressure of pipelines in the oil field is higher, the pipelines can only be connected in a metal buckling mode to ensure the connection strength. However, the wall thickness of the metal crimping connector can cause the pipe system to shrink at the joint, so that dirt is easy to adhere to the joint. Therefore, the metal buckling joint at the end of the composite pipe needs to be subjected to pre-flaring treatment so as to ensure that the drift diameters of the pipeline systems are consistent. Although there are many types of existing flaring machines, the flaring principle is basically similar, and a flaring die is plugged into the end of a softened plastic pipe through a power system so as to achieve the flaring purpose. For example, patent No. CN201921130203.7 discloses a plastic pipe flaring device. This device is through heating plastic tubing, treats that tubular product softens the back and packs into the tubular product tip with the expansion body, because the expansion body external diameter is greater than the tubular product internal diameter to this reaches the purpose of plastic tubing flaring. In the flaring mode, because the flaring body is axially plugged into the pipeline, the end part of the pipe can bear an axial force, and the softened pipe is very easy to be pressed to form folds, so that the flaring quality is influenced; moreover, the flaring mode can only be applied to plastic solid-wall pipes and can not be applied to non-metal composite pipes such as steel wire reinforcement and the like. Because the composite pipe is generally divided into an inner layer, a reinforcing layer and an outer layer, the flaring method is very easy to cause the inner layer to be extruded and to shrink inwards to damage the pipe, and the reinforcing layer and the outer layer cannot achieve the purpose of flaring. And the existing flaring machine is generally heavier, and is inconvenient for construction sites and rush repairs.
