At present, plastic composite pipes used in the field of oil fields are all medium-high pressure pipes which are all connected by metal joints, and in actual operation, external buckling and pressing equipment is generally adopted, so that the equipment is large in size, heavy and complex in operation. From this, the oil field pipe job site all is basically in remote mountain deep mountain, and the topography is very complicated, and the erection equipment lightweight, the problem of simple operation nature is the primary consideration. Meanwhile, the adoption of external buckling and pressing equipment can lead to the great reduction of the drift diameter of the metal joint and lead to the metal joint always bearing great pulse stress. However, a small amount of connecting mechanisms adopting an internal expansion form are not eliminated, and although the connecting device is light and convenient, the connecting device has larger limitation and is only suitable for bonded and thin-walled composite pipes. In addition, the metal joint with the internal expansion amount smaller than 5mm adopts non-bonding type pipes for most high-pressure pipes in the oil field at present, the wall thickness is large, the buckling amount is large (7-10 mm), and only external buckling connection equipment can be adopted.
In summary, the metal joint and plastic composite pipe connection equipment in the market has single function, and can only solve the problems of difficult movement, complex operation, unreasonable drift diameter of the metal joint, small size, incapability of adapting to various high-pressure composite pipes, high manufacturing cost and the like due to the large size and difficulty in moving of one connection mode.
