Example Embodiment

[0009] In the following, the present invention will be further described with embodiments in conjunction with the accompanying drawings.

[0010] A pair of self-locking sealing plugs 13, 18 are made of steel. One end of the plug 13 is in the shape of a flat-top bottle stopper. The outer diameter of the stopper body is slightly smaller than the inner diameter of the lined plastic pipe 12. The diameter of the flat cover of the stopper body is equal to the outer diameter of the steel pipe 11, and an axial through hole 21 is opened in the stopper body. The outer port of the axial through hole 21 is equipped with a self-closing quick connector 8 for inflation, and a pull ring 14 is provided on the inner end of the plug; the other end plug 18 is a straight plunger with a diameter slightly smaller than the inner diameter of the lined plastic pipe, outside the straight plunger The end is provided with a ring groove that matches with the semicircular snap ring 19. A pull ring 20 is provide...

Abstract

This invention relates to one medium heating steel tube plastic device, which comprises the following parts: sealing head on both ends of steel tube; charging structure; steel tube sending machine and heating device, wherein, the heating device adopts medium frequency induce heating coil; the said sealing head device is one pair of self-locking block with one end in plat cover shape and with hole in center and with self-sealed rap0id joint and with other end as column plug opened with semi-round card groove with two block ends connected through spring. This invention alters traditional large fuel strove heating device and complex gas cylinder sealed head device.

Description

technical field [0001] The invention relates to a processing device for a plastic-lined composite steel pipe. Background technique [0002] The existing plastic-lined steel pipe processing device is composed of a cylinder that seals the two ends of the steel pipe lined with plastic pipe by top pressure, an air charging device that pressurizes the plastic-lined steel pipe through the cylinder, a fuel heating furnace and a water spray cooling device. . The disadvantages of this processing device are that the structure is complex, the equipment is bulky, and the production efficiency is not high. Contents of the invention [0003] The purpose of the present invention is to provide a processing device with simple structure, small equipment volume, convenient operation and high production efficiency for the production of plastic lining of steel pipes. [0004] The technical solution to achieve the above purpose is: it includes the...
