Therefore, impurities such as rust layers and oil stains on the inner wall of the spiral pipe can fall off more easily, the cleaning difficulty of the spiral pipe is lowered, all the bristles rotate to clean the inner wall of the spiral pipe, all the bristles make contact with a welding seam from the side portion, all the bristles are directly inserted into the welding seam on the inner wall of the spiral pipe, and the welding seam is cleaned more conveniently. And therefore, the cleaning effect on the spiral pipe is improved.

Guide plate with water cooling device

The utility model provides a guide plate with a water cooling device, which is characterized in that the structure of the existing guide plate for hot rolling of seamless steel pipes is improved, that is, a water cooling guide groove arranged along the rolling center line of the guide plate is arranged in a guide plate body; a water outlet hole which is vertically communicated with the water-cooling guide groove is formed in a rolling center line of the working surface of the guide plate body, and water-cooling guide pipes with different structures are arranged in the water-cooling guide groove; during rolling, circulating water cooling and lubrication are carried out between the guide plate and a seamless steel pipe red hot steel billet, so that the failure probability of oxidative wear, abrasive wear, hot cracks and the like of the guide plate at high temperature is greatly reduced, and the service life of the guide plate is greatly prolonged. Through actual working condition tests, the improved guide plate for the hot-rolled seamless steel pipe is very remarkable in anti-abrasion effect, the effect of rolling more than 3000 steel pipes can be achieved, the service life is more than 1.5 times that of an existing guide plate, therefore, the replacement period of the guide plate is prolonged, and the production cost is reduced.
