    Abstract: Embodiments of the present disclosure provide systems and methods for assembly of tubular joints which overcome the drawbacks and limitations of conventional joints. In certain embodiments, the tubular joints may comprise threaded joints used in oil exploration. Joints may be assembled using a combination of a) position control, b) specific production tolerances for thread parameters, and c) coatings applied on threaded areas of the joint. In further embodiments, the tubular joints may have no torque shoulder and/or metal to metal seals. In additional embodiments, the joints may be further assembled and disassembled several times without application of dope or grease and exhibit enhanced sealability. Beneficially, embodiments of the present disclosure may provide high tolerance, precisely assembled joints that provide improved performance (e.g., mechanical performance, sealability, corrosion resistance, lubrication) and reliability over non-premium connections without the expense associated with premium connections.

    Abstract translation: 本公开的实施例提供了用于组装管状接头的系统和方法，其克服了常规接头的缺陷和限制。 在某些实施例中，管状接头可以包括用于石油勘探中的螺纹接头。 接头可以使用以下组合进行组装：a）位置控制，b）螺纹参数的特定生产公差，以及c）施加在接头螺纹区域上的涂层。 在另外的实施例中，管状接头可以没有扭矩肩部和/或金属对金属密封件。 在另外的实施例中，可以将接头进一步组装和拆卸多次，而不施加涂料或油脂并显示出增强的密封性。 有利地，本公开的实施例可以提供高公差，精确组装的接头，其提供改进的性能（例如，机械性能，密封性，耐腐蚀性，润滑性）以及非优质连接的可靠性，而无需与高级连接相关联的费用。

    Abstract: There is provided a lubricant for hot plastic working, which contains 20 to 40 mass % of iron oxide and 10 to 30 mass % of sodium silicate, wherein impurities are 3 mass % or less, and the lubricant contains 40 to 60 mass % of water. By virtue of combined action of these components, the lubricant exhibits excellent lubricity and suppliability and does not adversely affect the corrosion resistance of product. The lubricant is suitably used for lubricating a guide shoe in piercing-rolling, for example, a high-Cr steel and achieves a great effect of preventing a seizure flaw from occurring on the outer surface of product by being applied directly to the outer surface of a workpiece just before piercing rolling, preferably, within one second before starting piercing rolling.
