The paper analyzes the problems of exploitation of pipe outlets for the oil and gas industry and describes the special design of the outlet’s vane, which allows to extend its service life. However, this special shape of the vane requires new manufacturing technologies. The paper lists the technical requirements for the finished model of the outlet and the method of its manufacture. Based on them, an analysis was carried out, and has been proposed the application of additive technologies for the manufacture of a steel pipe outlet with the vane, namely, the method of Selective Laser Melting (SLM). The advantages and particularities of the method’s application are described, as well as the stages of the manufacturing process for manufacturing an outlet with a special shape of the vane.

本文分析了石油和天然气行业管道出口的开采问题，并描述了出口叶片的特殊设计，可以延长其使用寿命。然而，这种特殊形状的叶片需要新的制造技术。文中列出了出口成品模型的技术要求及其制作方法。在此基础上进行了分析，提出了应用增材技术制造带叶片的钢管出口，即选择性激光熔化法（SLM）。描述了该方法应用的优点和特殊性，以及用于制造具有特殊叶片形状的出口的制造过程的各个阶段。
