中国石油网消息：9月15日，从宝石管业了解到，这个公司自主研发的“一种管端坡口钝边平整度修磨装置及方法”获得国家发明专利授权。这标志着其在超大口径管材制造及质量控制领域取得重要技术突破。

China Oil News: On September 15th, Gemstone Pipe Industry was informed that this company has obtained a national invention patent for its independently developed "A Device and Method for Polishing the Flatness of the Edge of the Pipe End Groove". This indicates that it has made an important technological breakthrough in the field of manufacturing and quality control of ultra-large diameter pipe materials.

长期以来，管端钝边加工精度不足不仅是制约超大口径管材制造的生产痛点，也是影响管道焊接施工质量及效率提升的突出难题。鉴于此，这个公司技术团队聚焦超大口径管材管端坡口加工关键工序，实施管端坡口钝边尺寸工艺优化，经过多轮试验调试、迭代改进及现场实测验证，研发出管端坡口钝边平整度修磨装置及配套工艺方法，有效解决了超大口径管材坡口钝边修磨精度控制难题，进一步提升了管材坡口加工质量及生产作业效率。

For a long time, the insufficient processing accuracy of the sharp edges at the pipe ends has not only been a major production pain point restricting the manufacturing of ultra-large diameter pipes, but also a prominent problem affecting the quality and efficiency improvement of pipeline welding construction. In view of this, the technical team of this company focused on the key process of pipe end groove processing for ultra-large diameter pipes, implemented the process optimization of the blunt edge size at the pipe ends, and through multiple rounds of trial and debugging, iterative improvement and on-site measurement verification, developed a pipe end groove blunt edge flatness grinding device and corresponding process methods. This effectively solved the problem of controlling the grinding accuracy of the blunt edges at the pipe ends of ultra-large diameter pipes, and further improved the processing quality of the pipe ends and the production efficiency.

目前，该装置及方法已完成13.56万吨管材的现场应用，实现了管端切斜、钝边尺寸的精准化修磨，从根源上解决了传统人工打磨存在的打磨不均匀、尺寸偏差大、表面毛刺残留等诸多生产问题，显著提升了管端加工的平整度、规整度与产品一致性。与此同时，有效避免了人工打磨产生的安全风险，消除了超大口径钢管切斜缺陷。

At present, this device and method have been applied on-site for 135,600 tons of pipe materials, achieving precise grinding of the pipe ends and the size of the blunt edges. This has fundamentally solved many production problems such as uneven grinding, large size deviations, and residual surface burrs that existed in traditional manual grinding. It has significantly improved the flatness, regularity and product consistency of the pipe end processing. At the same time, it effectively avoids the safety risks caused by manual grinding and eliminates the defect of pipe skew in large-diameter steel pipes.

下一步，宝石管业将继续加快推进专利技术的产业化落地及规模化应用，将技术优势转化为产品优势和服务优势，推动生产一线工艺迭代，助力施工现场提质增效。

Next, the Gem Tube Industry will continue to accelerate the industrialization implementation and large-scale application of its patented technologies. It will transform its technological advantages into product and service advantages, promote the iterative improvement of production processes at the front line, and help enhance the efficiency and quality of construction sites.
