按 API 标准规定,石油管制造厂对其石油管产品,在接箍内丝扣和管端外丝扣部分应附有内外丝扣保护环。保护环应能对管端或管接箍的丝扣及其端面起到保护作用。在库存、运输和经常搬运时保证丝扣不致被损坏。为了生产符合使用要求的油管保护环,我们制定了一套可行的保护环生产工艺,对一些通用设备加以改革,形成了一条油管钢保护环生产作业线。本文介绍了 According to API standards, oil pipe manufacturing plant for its oil pipe products, in the collar and the pipe end of the threaded part of the wire should be attached to the inner and outer threaded retaining ring. The guard ring should be able to protect the pipe end or the pipe thread and the end face of the pipe coupling. In the stock, transport and regular handling to ensure that the screw will not be damaged. In order to produce tubing protection rings that meet the requirements for use, we have developed a viable production line for the protection rings, reformed some general purpose equipment and formed a production line for tubing protection rings.
