In addition, the sandblasting machine has the following advantages that: the sandblasting machine has effects of other blasting ways, and provides good sandblasting effects after the actual production, the work efficiency is high, the processing cost is significantly reduced. With the actual production practices, the production output is increased by 40%, and the qualified rate of the product is improved by 5%.

Description

technical field [0001] The invention relates to a sand blasting machine, in particular to an online automatic pipe end thread sand blasting machine. Background technique [0002] In oil drilling, the use of seamless steel pipes with high strength, good toughness and high corrosion resistance has become a development trend. At present, the production of high-corrosion-resistant nickel-based steel pipes and chromium-containing steel pipes requires a relatively special treatment process, especially for the sandblasting treatment of the pipe end threads. The significance of the sandblasting treatment is to improve the physical properties of the pipe end threads of the steel pipes. In the past, sand blasting treatment required off-line processing, which caused quality problems of seamless steel pipe products and increased the cost of products. [0003] The research and application of special equipment for pipe end thread sandblasting and on-line automatic pipe end sandblasting m...
