Pipeline joint shot blasting machine (oil and gas pipeline joint sand blasting machine): it is a special equipment for sand blasting at the joint during the installation of oil and gas pipelines. When laying the oil pipeline (gas pipeline), the finished pipeline is shot blasted and treated with anti-corrosion treatment, and then transported to the installation site section by section. The field installation personnel weld the pipeline section by section, so that the quality of the weld treatment becomes the key to affect the quality of the whole transmission pipeline. The automatic weld sandblasting machine designed and developed by Qingdao friendship casting machine Co., Ltd. is very good This problem has been solved. Pipe joint shot peening machine: it has the advantages of high efficiency and no dead angle. It can eliminate the residual stress of the pipe joint weld, increase the surface roughness of the pipe, increase the adhesion of the anti-corrosion
