    • The present invention relates to the flange structure of a drilling riser in order to continuously couple pipes constituting a drilling riser using fastening bolts. The flange structure of a drilling riser comprises: a flange body which is fixed to each end of a pipe and has a plate shape; multiple bolt slots which are formed at the edge of the flange body and have an opening and into which a fastening bolt is vertically inserted from the side of the flange body to be interlocked; and bolt holders which prevent the fastening bolts from escaping from the bolt slots. The bolt holder includes perpendicular slot which is perpendicular to the bolt slot and extended from one side of the bolt slot and in which the fastening bolt inserted into the bolt slot to be interlocked by moving in the circumferential direction. According to the present invention, fastening bolts are inserted into bolt slots from the side of a flange body and are interlocked with the bolt slots, thereby easily inserting fastening blots into a flange body, and, particularly, fastening bolts inserted into bolt slots are inserted into perpendicular slots perpendicular to the bolt slots and are interlocked with the perpendicular slots, thereby preventing the fastening bolts from escaping and coupling flanges firmly.

    • PURPOSE: A water sampling pipe is provided to ensure the accuracy of measurement and to facilitate water sampling by positioning a strainer in a fracture zone for pulling out only the casing to prevent the collapse of the fracture zone. CONSTITUTION: A water sampling pipe comprises a casing(100), a first joint(200), a second joint(300), and a strainer(400). The first joint is integrally installed in the lower end of the casing. The outer circumference of the first joint is formed with a hooking protrusion(230). The second joint is formed with a hooking groove in order to be attached to or detached from the lower end of the first joint by horizontally rotating. The strainer is positioned in a fracture zone due to the separation of the first and second joints when pulling out the casing after forming a tubular well.
    • 目的:提供一个取水管,以确保测量的准确性,并通过将过滤器放置在断裂区域中来方便取水,以便仅拉出外壳以防止断裂区的塌陷。 构成:取水管包括壳体(100),第一接头(200),第二接头(300)和过滤器(400)。 第一接头一体地安装在壳体的下端。 第一接头的外周形成有钩挂突起(230)。 第二接头形成有钩槽,以通过水平旋转而附接到第一接头的下端或从第一接头的下端分离。 由于在形成管状井之后拉出壳体时第一和第二接头的分离,过滤器被定位在断裂区域中。
